Overview
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.
Physical Examination
Vitals
ARDS may present with signs of shock or infection:
- Temperature (Temp, T): Hyperpyrexia ≥ 38 oC or 100.4 oF) or low temperature < 36 oC or 96.8 oF
- Blood pressure (BP): inappropriately low, with a low mean arterial pressure (MAP)
- Heart rate (HR): rapid (tachycardia > 100 beats/minute), normal, or slow (bradycardia < 60 beats/minute)
- Respiratory rate (RR): Tachypnea > 20 breaths/minute or bradypnea < 12 breaths/minute
- Peripheral capillary oxygen saturation (SpO2): low (< 90% on ambient air or a fraction of inspired oxygen, [FIO2] of 21% at sea level)
Physical Examination
The physical exam findings of a patient with ARDS vary according to the underlying cause, however, some commonly observed findings include:
- Respiratory distress (difficulty breathing)
- Cyanosis due to poor oxygenation or pallor due to poor perfusion
- Tachycardia or bradycardia on heart auscultation
- Coarse breath sounds, rhonchi, crackles, or decreased breath sounds on lung auscultation
- Cool extremities or reduced peripheral pulses due to poor perfusion
