Diagnostic Criteria for Acute Respiratory Distress Syndrome

In this article, we will discuss about Diagnostic Criteria for Acute Respiratory Distress Syndrome. So, let’s get started.

Diagnostic Criteria

Acute respiratory distress syndrome is defined as an acute hypoxic respiratory failure characterized by extensive bilateral pulmonary infiltrates, rapid onset dyspnea, refractory hypoxemia, decreased lung compliance, and respiratory failure.

It is considered a medical emergency and carries a high mortality rate (40-60%).

Following are the diagnostic criteria  for ARDS:

1. Impaired oxygenation PaO2/FiO2 ratio <200 mmHg (mild (200-300 mmHg, moderate 100-200 mmHg, and severe <100 mmHg by Berlin definition)

2. Normal pulmonary capillary wedge pressure (PCWP) <18 mm with normal left atrial pressure.

3. Chest x-ray showing diffuse bilateral lung infiltrates.

Diagnosis of ARDS

In this article, we will discuss about the diagnosis of ARDS. So, let’s get started.

According to the American-European Consensus Conference, the diagnostic criteria of ARDS is:-

Acute onset of dyspnea, tachypnea, and hypoxemia.

Profound hypoxemia and absence of left atrial hypertension

Chest radiography revealing bilateral lung infiltration

PaO2/FiO2 equivalent or less than 200 regardless of positive end-expiratory pressure

Pulmonary artery wedge pressure of 18 mmHg or less.

Table for management of ARDS is given below:-
