There are no physical exam findings specific to or [[pathognomonic]] of ARDS. The most notable physical exam findings tend to be those of the underlying illness or injury, as well as those of [[respiratory distress]], [[critical illness]], [[shock]], and [[end organ damage]].
There are no [[pathognomonic]] physical exam findings of ARDS. The most notable physical exam findings include [[respiratory distress]] as well as findings indicative of the underlying illness, [[injury]], [[shock]], and [[end organ damage]].


The first signs of ARDS typically present within 24 to 48 hours of the precipitating [[illness]] or [[injury]] and progress over the course of 1 to 2 weeks. The early clinical features of ARDS include:
==Physical Examination==
*[[Hypoxemia]] (a declining peripheral blood oxygen saturation [SpO<sub>2</sub>] on [[pulse oximetry]] or a declining partial pressure of oxygen (PaO<sub>2</sub>) on [[arterial blood gas]] analysis) requiring high concentrations of supplemental oxygen (i.e., a higher [[fraction of inspired oxygen]] (FIO<sub>2</sub>)) or positive pressure ventilation (i.e., a higher [[continuous positive airway pressure]] (CPAP) or a higher [[positive end-expiratory pressure]] (PEEP)) in order to maintain acceptable blood oxygenation
The physical exam findings of a patient with ARDS vary according to the underlying cause and typically develop within 24 to 48 hours of the precipitating [[illness]] or [[injury]] and progress over the course of 1 to 2 weeks. Common physical findings include:
*[[Tachypnea]]
*[[Dyspnea]]
*[[Tachycardia]]

Overview

There are no pathognomonic physical exam findings of ARDS. The most notable physical exam findings include respiratory distress as well as findings indicative of the underlying illness, injury, shock, and end organ damage.

Physical Examination

The physical exam findings of a patient with ARDS vary according to the underlying cause and typically develop within 24 to 48 hours of the precipitating illness or injury and progress over the course of 1 to 2 weeks. Common physical findings include:

Vital Signs

The presence of the following signs of shock or infection on physical examination are highly suggestive of ARDS:

Skin

Lungs

Heart

Extremities
