Utilization of Airway Pressure Release Ventilation as a Rescue Strategy in COVID-19 Patients: A Retrospective Analysis.

Background: Airway Pressure Release Ventilation (APRV) is a pressure controlled intermittent mandatory mode of ventilation characterized by prolonged inspiratory time and high mean airway pressure. Several studies have demonstrated that APRV can improve oxygenation and lung recruitment in patients with Acute Respiratory Distress Syndrome (ARDS). Although most patients with COVID-19 meet the Berlin criteria for ARDS, hypoxic respiratory failure due to COVID-19 may differ from traditional ARDS as patients often present with severe, refractory hypoxemia and significant variation in respiratory system compliance.

An atypical presentation of pulmonary sequestration.

Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract and is commonly complicated by recurrent infections and presents with respiratory failure. We report an atypical clinical presentation of postprandial abdominal pain and cramps in a patient with intralobar PS.
