Table 3 High-altitude ARDS severity grades [1].

	Mild	Moderate	Severe
Oxygenation	200 mmHg× (barometric pressure/760)^a	100 mmHg× (barometric pressure/760)^a	PaO/FiO ≤100 mmHg ×(barometric pressure/760) with PEEP ≥5 cmHO^a
ARDS – Acute respiratory distress syndrome; CPAP – continuous positive airway pressure; FiO – fraction of inspired oxygen; PaO – partial pressure of arterial oxygen; PEEP – positive end-expiratory pressure. ^a This may be delivered noninvasively in the mild acute respiratory distress syndrome group.
