Answer

In general, use endotracheal intubation and mechanical ventilation when patients with CPE remain hypoxic despite maximal noninvasive supplemental oxygenation, when patients have evidence of impending respiratory failure (eg, lethargy, fatigue, diaphoresis, worsening anxiety), or when patients are hemodynamically unstable (eg, hypotensive, severely tachycardic).

Mechanical ventilation maximizes myocardial oxygen delivery and ventilation. Positive end-expiratory pressure is generally recommended to increase alveolar patency and to enhance oxygen delivery and carbon dioxide exchange.
