1. RRs >25 breaths /min

2. SpO2 < 93%

1. RRs >25 breaths/min

2. PaO2 / FiO2 ≤ 300 mmHg when the patients breathed oxygen at a flow rate > 10 l/min over 15 min

3. PaCO2 ≤ 45 mmHg

4. An absence of clinical history of underlying chronic respiratory failure

1. A need for oxygen greater than 6 L/min to maintain SpO2 > 95%

2. Symptoms of respiratory distress*

1. SpO2 ≤ 92% on air

2. RRs ≥22 breaths/min

  1. RRs respiratory rates, SpO 2 peripheral capillary oxygen saturation, PaO 2 arterial partial pressure of oxygen, FiO 2 fraction of the inspired oxygen, PaCO 2 partial pressure of arterial carbon dioxide, Min minute; *: tachypnea >30/min, intercostal recession, labored breathing, and/or dyspnea at rest
