How ARDS is diagnosed

There's no specific test to diagnose ARDS. A full assessment is needed to identify the underlying cause and rule out other conditions. This assessment is likely to include:

  • a physical examination
  • blood tests to measure the amount of oxygen in the blood and check for an infection
  • a pulse oximetry test where a sensor attached to the fingertip, ear or toe is used to measure how much oxygen the blood is absorbing
  • a chest X-ray and a computerised tomography (CT) scan to look for evidence of ARDS
  • an echocardiogram a type of ultrasound scan used to create a picture of the heart
