• #1 Acute Respiratory Distress Syndrome: Diagnosis and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2012/0215/p352.html

  Acute respiratory distress syndrome manifests as rapidly progressive dyspnea, tachypnea, and hypoxemia. Diagnostic criteria include acute onset, profound hypoxemia, bilateral pulmonary infiltrates, and the absence of left atrial hypertension. […] The American-European Consensus Conference (AECC) has published diagnostic criteria for ARDS: acute onset; ratio of partial pressure of arterial oxygen to fraction of inspired oxygen (PaO2/FiO2) of 200 or less, regardless of positive end-expiratory pressure; bilateral infiltrates seen on frontal chest radiograph; and pulmonary artery wedge pressure of 18 mm Hg or less when measured, or no clinical evidence of left atrial hypertension. […] Because pneumonia is a leading cause of ARDS, distinguishing patients with uncomplicated pneumonia from those who have pneumonia complicated by ARDS presents a greater diagnostic challenge. In general, a patient with uncomplicated pneumonia may have signs of systemic and pulmonary inflammation (i.e., fever, chills, fatigue, sputum production, pleuritic chest pain, and localized or multifocal infiltrates); accompanying hypoxia should respond to oxygen administration. If hypoxia does not correct with oxygen administration, ARDS should be suspected and confirmed based on AECC diagnostic criteria.

  Acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by poor oxygenation and non-compliant or „stiff” lungs. […] ARDS is an acute disorder that starts within seven days of the inciting event and is characterized by bilateral lung infiltrates and severe progressive hypoxemia in the absence of any evidence of cardiogenic pulmonary edema. According to the Berlin definition, ARDS is defined by acute onset, bilateral lung infiltrates on chest radiography or CT scan of a non-cardiac origin, and a PaO2/FiO2 ratio of less than 300 mm Hg. […] The diagnosis of ARDS is based on the following criteria: acute onset, bilateral lung infiltrates on chest radiography or CT scan (who are of non-cardiac origin), and a PaO2/FiO2 ratio of less than 300 mm Hg. It is further sub-classified into mild (PaO2/FiO2 200 mm Hg, but 300 mm Hg), moderate (PaO2/FiO2 100 mm Hg, but 200 mm Hg), and severe (PaO2/FiO2 100 mm Hg) subtypes.

  https://emedicine.medscape.com/article/165139-overview

  Acute respiratory distress syndrome (ARDS) is recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. Initially, the American-European Consensus Conference (AECC) defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patients arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. […] This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. ARDS is defined by timing (within 1 week of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on at least 5 cm of H2O end expiratory pressure. The three categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 100).

  Acute respiratory distress syndrome (ARDS) is a non-cardiogenic pulmonary oedema and diffuse lung inflammation syndrome that often complicates critical illness. The clinical definition of ARDS was updated in 2024 to include both intubated and non-intubated patients and to allow diagnosis of ARDS in resource-limited settings. Diagnosis of ARDS is based on fulfilling three criteria: […] Acute onset (within 1 week) […] Bilateral opacities on chest radiography or computed tomography (CT), or bilateral B lines and/or consolidations on ultrasound not fully explained by effusions, atelectasis, or nodules/masses […] PaO/FiO (arterial to inspired oxygen) ratio of 300 or SpO2/FiO2 (pulse oximetric saturation to inspired oxygen) ratio of 315. […] If no risk factors for ARDS are present, then acute pulmonary oedema as a result of heart failure should be ruled out.

  There’s no specific test for ARDS. Healthcare professionals base the diagnosis on physical exams, chest X-rays and oxygen levels. It’s also important to rule out other diseases and conditions, such as certain heart problems that can lead to similar symptoms. […] A chest X-ray can show which parts of your lungs, and how much of the lungs, have fluid in them and whether your heart has gotten bigger. Another test called a CT scan combines X-ray images taken from many directions and creates cross-sectional views of internal organs. CT scans can give detailed information about the structures within the heart and lungs. […] A test using blood from an artery can measure your oxygen level. Other types of blood tests can check for symptoms of infection or other medical conditions. If your healthcare professional thinks that you have a lung infection, secretions from your airway may be tested to find the cause of the infection.

  Lung ultrasonography (LUS) is invaluable for diagnosing and managing adult respiratory distress syndrome (ARDS) because it is non-invasive, bedside, and widely available in both high- and low-resource settings. This article summarizes the technique and utility of LUS in ARDS patients. […] The Kigali modification of the Berlin definition first proposed LUS criteria for ARDS, specifically designed for limited resource settings where access to imaging and ventilators is scarce. With the Kigali modification, bilateral B-lines or consolidations on LUS were allowed to fulfil the imaging criteria for ARDS. In comparison to the gold standard computed tomography (CT) in high-resource settings, these criteria proved to be highly sensitive but with low to moderate specificity. […] A useful development is the LUS-ARDS score, a data-driven and externally validated method based on LUS-scores from both the left and right lungs combined with the identification of an abnormal pleural line in the antero-lateral regions. This method involves more complexity than the Kigali modification, but exhibits higher accuracy in diagnosing and excluding ARDS.

• #1 Acute Respiratory Distress Syndrome (ARDS)

  https://my.clevelandclinic.org/health/diseases/15283-acute-respiratory-distress-syndrome-ards

  Acute respiratory distress syndrome (ARDS) is a lung injury that happens when fluids build up in small air sacs (alveoli) in your lungs. ARDS prevents your lungs from filling up with air and causes dangerously low oxygen levels in your blood (hypoxia). Healthcare providers typically diagnose a person as having mild, moderate or severe respiratory distress syndrome. They determine that level by comparing the level of oxygen in your blood with the amount of oxygen that needs to be given to achieve a healthy blood oxygen level. […] Healthcare providers diagnose ARDS based on a physical exam and the results of several tests. Since the symptoms of ARDS are similar to chronic lung or heart conditions, your provider may need to rule out other causes. […] A healthcare provider may order a combination of tests, including: Chest X-ray to measure fluid in your lungs. A blood test to measure oxygen levels in your blood and determine the severity of ARDS. Echocardiogram (ultrasound of your heart) to evaluate heart function. Electrocardiogram (or EKG) to measure your hearts electrical activity. A fingertip sensor (pulse oximetry) for constant monitoring of oxygen levels. A computed tomography (CT) scan to provide more detailed information about your lungs. Sampling of secretions from your airways to find the cause of an infection.

  The level of oxygen in the blood can be measured without taking a blood sample by using a sensor placed on a finger or an earlobea procedure called pulse oximetry. […] The level of oxygen (along with carbon dioxide) in the blood can also be measured by analyzing a blood sample taken from an artery (arterial blood gas measurement). […] Chest x-rays show fluid in spaces that should be filled with air. Further tests may be needed to ensure that heart failure is not the cause of the problem.

  Because the symptoms of ARDS are like those of certain heart problems, your healthcare professional may recommend heart tests such as: Electrocardiogram. This painless test, which also is known as an ECG, tracks the electrical activity in your heart. During the test, a healthcare professional attaches several wired sensors to your body. […] Echocardiogram. This test uses sound waves to create pictures of the heart. It shows how blood moves through the heart chambers and heart valves, and whether there are changes in the structures of your heart.

• #1 ARDS Diagnosis May Be Underrecognized, Good Treatment Options Exist < Yale School of Medicine

  Acute Respiratory Distress Syndrome (ARDS) has been defined in a variety of different ways, explained Moss. Importantly, it is a syndrome and that means that we define it based on clinical criteria. In 2012, the Berlin definition was created to streamline the diagnosis. […] How well do physicians do with identifying the disease? Moss cited a 2016 JAMA study which showed that ARDS is common in intensive care units (ICU) around the world, and almost 25% of patients on mechanical ventilation will meet criteria for ARDS. The disease is underrecognized by physicians and healthcare professionals. Of the patients with ARDS, only 60% had documentation in their chart that they actually had ARDS. […] We now have specific ways of treating ARDS, and if you are not recognizing ARDS, you arent treating people in the right way, said Moss.

• #1 Advances in Biomarkers for Diagnosis and Treatment of ARDS

  https://www.mdpi.com/2075-4418/13/21/3296

  Acute respiratory distress syndrome (ARDS) is a common and fatal disease, characterized by lung inflammation, edema, poor oxygenation, and the need for mechanical ventilation, or even extracorporeal membrane oxygenation if the patient is unresponsive to routine treatment. In this review, we aim to explore advances in biomarkers for the diagnosis and treatment of ARDS. […] The use of biomarkers is pivotal in diagnosing, predicting the course, and treating ARDS. They can be used to distinguish between different types of conditions, evaluate their severity, and track the effectiveness of treatment. […] The classification of the biomarkers discussed in this review is presented in Figure 1. […] The progress made in recognizing ARDS biomarkers affords us a wider viewpoint into the disease’s pathophysiology, diagnosis, and therapy.

[…] The problem is that sometimes it can be difficult to recognize, so we are desperate for new tools for ARDS detection and monitoring. […] Clinical diagnosis is based on the Berlin ARDS clinical criteria, which is imprecise in application, and there currently are no established biomarkers to support ARDS diagnosis. […] There is a significant unmet clinical need for early, rapid, and accurate ARDS diagnosis, as well as clinical trajectory monitoring of ARDS to ensure resolution with treatment.

• #1 A structured diagnostic algorithm for patients with ARDS | Critical Care | Full Text

  https://ccforum.biomedcentral.com/articles/10.1186/s13054-023-04368-y

  Patients admitted to the intensive care unit (ICU) with acute respiratory failure frequently fulfil the criteria for acute respiratory distress syndrome (ARDS). The diagnosis is based on radiological, physiological, and clinical criteria described in the Berlin definition. […] The diagnosis of ARDS is largely based on hypoxic respiratory failure and the detection of pulmonary edema, from which hydrostatic cardiogenic pulmonary edema must be excluded. It is therefore essential that false positive results are excluded as much as possible by means of non-invasive imaging. Ultrasound of the lungs is superior to chest X-ray for detecting and ruling out pleural effusion. […] The presence of ARDS should trigger both a standardized set of evidence-based interventions (e.g., lung protective ventilation, restrictive fluid therapy) and, importantly, an investigation into the cause of the pulmonary injury.

  Your doctor will diagnose acute respiratory distress syndrome (ARDS) based on your medical history, a physical exam, and test results. ARDS can be difficult to diagnose and is often mistaken for another condition, so it is important to know your symptoms. […] To help diagnose ARDS, your doctor may ask you about any medical conditions or recent events that could be considered risk factors. […] Your doctor will examine you for signs of ARDS. […] To diagnose ARDS, your doctor may have you undergo some of the following tests and procedures. […] Blood tests measure the oxygen level in your blood, using a sample of blood taken from an artery. A low blood oxygen level might be a sign of ARDS. […] Lung imaging tests, such as a chest X-ray or computerized tomography (CT) scan, create detailed images of your lungs. […] Bronchoscopy can diagnose a lung problem when there is no clear cause of your ARDS.

  https://www.esicm.org/article-review-lung-safe-24h-ards-icm-2018/

  ARDS is persistently associated with unacceptably high mortality approximately 40%. Berlin definition criteria for defining ARDS are highly sensitive but, show limited specificity leading to a heterogeneous patient group potentially with false positives. LUNG SAFE SIESTA network studies highlighted that 24hrs after diagnosis a significant proportion of ARDS had resolved. […] Nearly 24% of these ARDS patients resolved (came out of Berlin definition criteria) whereas 76% persisted to fulfil ARDS diagnostic Berlin criteria on day 2. […] Severe ARDS identified at day 2 substantially increased mortality from 43% to 57% on day 2. […] Overall mortality was associated with higher PIP, lower PEEP, lower P:F ratios, age and respiratory SOFA scores. […] The concept of persistent ARDS and the notion that reclassification may improve specificity is very useful. […] The findings suggest fulfilment of Berlin ARDS criteria at day 2 may be more robust and a potentially useful secondary definition. […] This work also refreshes the debate regarding the utility of current ARDS definitions.

  Acute respiratory distress syndrome (ARDS) is defined by the acute onset of bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence of cardiogenic pulmonary edema. Workup includes selected laboratory tests, diagnostic imaging, hemodynamic monitoring, and bronchoscopy. ARDS is a clinical diagnosis, and no specific laboratory abnormalities are noted beyond the expected disturbances in gas exchange and radiographic findings. […] When an extra-pulmonary etiology is suspected, patients should be given a COVID test. If pneumonia is suspected, sputum culture, respiratory mutiplex polymerase chain reaction (PCR), antigen tests, and blood cultures are required for diagnosis. […] In ARDS, if the partial pressure of oxygen in the patients arterial blood (PaO2) is divided by the fraction of oxygen in the inspired air (FiO2), the result is 300 or less. For patients breathing 100% oxygen, this means that the PaO2 is less than 300.

  Acute respiratory distress syndrome (ARDS) is a critical, non-cardiogenic pulmonary edema, instigated by various intra-pulmonary (e.g., pneumonia, aspiration) or extra-pulmonary factors (e.g., sepsis, acute pancreatitis, trauma). It results in severe hypoxemia, reduced lung compliance, increased arteriovenous shunting, and increased physiological dead space. […] Notably, although ARDS is a common disease in the ICUs, clinician awareness of ARDS is still limited, with approximately 40% of ARDS cases undiagnosed, indicating a potential underestimation of ARDS incidence. […] The newly introduced definition of ARDS expands its diagnostic criteria, permitting SpO2/FiO2315 and SpO297% (SpO2/FiO2 becomes invalid when SpO297%) as benchmarks for hypoxemia.

• #2 Biomarkers for the acute respiratory distress syndrome: how to make the diagnosis more precise

  https://atm.amegroups.org/article/view/15708/html

  The acute respiratory distress syndrome (ARDS) is an acute inflammatory process of the lung caused by a direct or indirect insult to the alveolar-capillary membrane. Currently, ARDS is diagnosed based on a combination of clinical and physiological variables. […] The lack of a specific biomarker for ARDS is arguably one of the most important obstacles to progress in developing novel treatments for ARDS. […] ARDS cannot be diagnosed by a single laboratory test. Since no specific ARDS biomarker has yet been described, it is likely that the incidence of what we currently consider to be ARDS is overestimated, since patients with transient or persistent hypoxemic respiratory failure from other diseases accompanied with bilateral pulmonary infiltrates could be erroneously diagnosed as having ARDS.

  Acute respiratory distress syndrome (ARDS) is noncardiogenic pulmonary edema that manifests as rapidly progressive dyspnea, tachypnea, and hypoxemia. Diagnostic criteria include onset within one week of a known insult or new or worsening respiratory symptoms, profound hypoxemia, bilateral pulmonary opacities on radiography, and inability to explain respiratory failure by cardiac failure or fluid overload. […] The Berlin criteria used for the diagnosis of ARDS in adults. These criteria are based on timing of symptom onset (within one week of known clinical insult or new or worsening respiratory symptoms); bilateral opacities on chest imaging that are not fully explained by effusions, lobar or lung collapse, or nodules; the likely source of pulmonary edema (respiratory failure not fully explained by cardiac failure or fluid overload); and oxygenation as measured by the ratio of partial pressure of arterial oxygen (Pao2) to fraction of inspired oxygen (Fio2). ARDS is classified as mild, moderate, or severe based on the following criteria: […] Mild: 200 mm Hg Pao2/Fio2 ratio 300 mm Hg with positive end-expiratory pressure (PEEP) or continuous positive airway pressure 5 cm H2O. […] Moderate: 100 mm Hg Pao2/Fio2 ratio 200 mm Hg with PEEP 5 cm H2O. […] Severe: Pao2/Fio2 ratio 100 mm Hg with PEEP 5 cm H2O.

  Acute respiratory distress syndrome (ARDS) is a common and devastating condition which can affect all adult patients – eg, medical, surgical and obstetric patients. It occurs when non-cardiogenic pulmonary oedema (secondary to acute damage to the alveoli) leads to acute respiratory failure. […] The Berlin criteria are used for the diagnosis of ARDS in adults. […] According to the Berlin definition, ARDS is an acute form of diffuse lung injury occurring in patients with a predisposing risk factor, meeting the following criteria: Onset within one week of a known clinical insult or new/worsening respiratory symptoms. Presence of bilateral opacities on CXR, not fully explained by effusion, lobar/lung collapse, or nodules. Diagnosis of respiratory failure not fully explained by cardiac failure or fluid overload. Presence of hypoxaemia, as defined by a specific threshold of the PaO2/FiO2 ratio measured with a minimum requirement of positive end-expiratory pressure (PEEP) 5 cm H2O.

  In a new report posted online in the American Journal of Respiratory and Critical Care Medicine, a global consensus conference of 32 critical care experts with broad international representation and from diverse backgrounds has proposed a new definition of acute respiratory distress syndrome (ARDS). […] The report, which builds on the 2012 Berlin Definition of ARDS, will be published Jan. 1, 2024 in the American Thoracic Society’s AJRCCM. […] Leaders in the field saw the need for an expanded definition due to new research and developments in the diagnosis and treatment of ARDS such as: […] Expanded use of pulse oximetry in place of measurement of arterial blood gases (oxygen and carbon dioxide, which are measured through a blood draw). Recent clinical trials in ARDS have used SpO2/FIO2 (as measured by pulse oximetry) for patient selection and ARDS patients diagnosed using pulse oximetry measurement have similar outcomes to those diagnosed using arterial gas measurement. […] As an alternative to arterial blood gas measurements, use arterial oxygen tension (SpO2/FIO2), as measured with pulse oximetry, for ARDS diagnosis and assessment of severity if SpO2 is less than or equal to 97 percent. This measurement will help identify hypoxemia earlier, making trials and early interventions with non-intubated patients more feasible. […] The new definition will likely enhance recognition of ARDS in many patients at an earlier stage of their respiratory failure, when interventions are more likely to succeed, said Dr. Matthay.

  Acute respiratory distress syndrome (ARDS) is a lung injury that happens when fluids build up in small air sacs (alveoli) in your lungs. ARDS prevents your lungs from filling up with air and causes dangerously low oxygen levels in your blood (hypoxia). Healthcare providers typically diagnose a person as having mild, moderate or severe respiratory distress syndrome. They determine that level by comparing the level of oxygen in your blood with the amount of oxygen that needs to be given to achieve a healthy blood oxygen level. […] Healthcare providers diagnose ARDS based on a physical exam and the results of several tests. Since the symptoms of ARDS are similar to chronic lung or heart conditions, your provider may need to rule out other causes. […] A healthcare provider may order a combination of tests, including: Chest X-ray to measure fluid in your lungs. A blood test to measure oxygen levels in your blood and determine the severity of ARDS. Echocardiogram (ultrasound of your heart) to evaluate heart function. Electrocardiogram (or EKG) to measure your hearts electrical activity. A fingertip sensor (pulse oximetry) for constant monitoring of oxygen levels. A computed tomography (CT) scan to provide more detailed information about your lungs. Sampling of secretions from your airways to find the cause of an infection.

  Acute respiratory distress syndrome (ARDS) is a noncardiogenic pulmonary edema and diffuse lung inflammation syndrome that often complicates critical illness. The clinical definition of ARDS was updated in 2024 to include both intubated and nonintubated patients and to allow diagnosis of ARDS in resource-limited settings. Diagnosis of ARDS is based on fulfilling three criteria: […] Acute onset (within 1 week) […] Bilateral opacities on chest radiography or computed tomography (CT), or bilateral B lines and/or consolidations on ultrasound not fully explained by effusions, atelectasis, or nodules/masses […] PaO/FiO (arterial to inspired oxygen) ratio of 300 or SpO2/FiO2 (pulse oximetric saturation to inspired oxygen) ratio of 315. If no risk factors for ARDS are present, then acute pulmonary edema as a result of heart failure should be ruled out.

  Blood gas tests show low oxygen levels in the blood. Sometimes the CO2 level will be low because the patient is hyperventilating to maintain their oxygen level. This test indicates how well the lungs are working. […] Sputum samples look at the substance that is coughed up to help identify the infection. Sputum, also called phlegm, contains white blood cells, dead cells, foreign debris thats inhaled, bacteria and other immune cells. […] Computerized tomography (CT) scans take cross section images of the area around the heart and lungs to identify possible sources of acute respiratory distress syndrome.

  ARDS is persistently associated with unacceptably high mortality approximately 40%. Berlin definition criteria for defining ARDS are highly sensitive but, show limited specificity leading to a heterogeneous patient group potentially with false positives. LUNG SAFE SIESTA network studies highlighted that 24hrs after diagnosis a significant proportion of ARDS had resolved. […] Nearly 24% of these ARDS patients resolved (came out of Berlin definition criteria) whereas 76% persisted to fulfil ARDS diagnostic Berlin criteria on day 2. […] Severe ARDS identified at day 2 substantially increased mortality from 43% to 57% on day 2. […] Overall mortality was associated with higher PIP, lower PEEP, lower P:F ratios, age and respiratory SOFA scores. […] The concept of persistent ARDS and the notion that reclassification may improve specificity is very useful. […] The findings suggest fulfilment of Berlin ARDS criteria at day 2 may be more robust and a potentially useful secondary definition. […] This work also refreshes the debate regarding the utility of current ARDS definitions.

• #3 Biomarkers for the acute respiratory distress syndrome: how to make the diagnosis more precise

  https://atm.amegroups.org/article/view/15708/html

  The lack of a specific biomarker for ARDS is arguably one of the main obstacles in the diagnosis and successful treatment of this syndrome. […] An ideal biological marker should provide information for identification of patients at risk for ARDS and with different ARDS phenotypes during the progression of lung injury. […] It is anticipated that using biomarkers for defining or stratifying subsets of ARDS patients that could benefit from a given therapy will have a major effect on both clinical practice and the development of new diagnostic tools and drugs. […] Despite major advances and developments in the last five decades with respect to the definition and management of ARDS, our understanding of the mechanistic underpinnings of ARDS is still in its infancy. […] The absence of a validated biomarker to define, diagnose, monitor responsiveness to therapy or predict prognosis of ARDS has limited progress in the field. […] Many candidate biomarkers have been investigated, but at the time of writing this review, a single, clear biomarker that is specific for ARDS has proven difficult to find. […] It is plausible that the best prediction approach will likely combine clinical predictors with several biomarkers.

  Diagnosing ARDS typically involves a combination of clinical evaluation, medical history review, physical examination, and various tests. Here’s an overview of the diagnostic process: […] The healthcare provider will ask about symptoms such as shortness of breath, rapid breathing, and low oxygen levels. They’ll also inquire about any underlying conditions or recent events that may have triggered ARDS, such as pneumonia, sepsis, trauma, or aspiration. […] The doctor will listen to the lungs with a stethoscope to detect abnormal breath sounds such as crackles and diminished breath sounds, which are common findings in ARDS. […] Blood tests are done to assess oxygen levels, carbon dioxide levels, and other markers of inflammation or organ dysfunction. […] The diagnosis of ARDS is based on specific criteria, including the degree of hypoxemia (low oxygen levels), bilateral infiltrates on chest imaging, absence of heart failure as the primary cause, and certain physiological criteria related to respiratory function.

  To exclude cardiogenic pulmonary edema, it may be helpful to obtain a plasma B-type natriuretic peptide (BNP) value and echocardiogram. A BNP level of less than 100 pg/mL in a patient with bilateral infiltrates and hypoxemia favors the diagnosis of ARDS rather than cardiogenic pulmonary edema. […] ARDS is defined by the presence of bilateral pulmonary infiltrates. The infiltrates may be diffuse and symmetric or asymmetric, especially if superimposed upon preexisting lung disease or if the insult causing ARDS was a pulmonary process, such as aspiration or lung contusion. […] In general, clinical evaluation and routine chest radiography are sufficient in patients with ARDS. However, computed tomography (CT) scanning may be indicated in some situations. […] As part of the workup, patients with ARDS should undergo two-dimensional echocardiography for the purpose of screening.

  Conventional mechanical ventilation in ARDS previously focused on normalizing arterial blood gas values. It is clear that ventilating with lower tidal volumes reduces mortality. […] PEEP improves oxygenation in ARDS by increasing the volume of aerated lung through alveolar recruitment, permitting the use of a lower FIO2. […] The best indicator of alveolar overdistention is measurement of a plateau pressure through an end-inspiratory hold maneuver; plateau pressure should be checked every 4 hours and after each change in PEEP or tidal volume. […] The optimal level of PEEP and the way to identify it have been debated. […] Mortality in ARDS was very high (40 to 60%) but has declined in recent years to 25 to 40% (1), probably because of improvements in mechanical ventilation and in treatment of sepsis.
