Acute respiratory distress syndrome (ARDS) is a widespread, inflammatory form of lung damage that manifests suddenly and may have several underlying causes. To lower the high mortality rate associated with ARDS, it is essential to identify it and treat it quickly.
- Patients with advancing dyspnea symptoms, an escalating need for oxygen, and alveolar infiltrates on chest imaging within 6 to 72 hours following a triggering event should be suspected of having ARDS.
- After 6 to 72 hours (or even up to a week) have passed since the triggering event, patients frequently report dyspnea and a decline in arterial oxygen saturation.
- Lab tests lack specificity. With or without a left shift, a complete blood count can reflect a variety of white blood cell counts (normal, increased, or lowered) (stress response).
