HFNO in Pneumonia Patients Presenting With Acute Hypoxemic Respiratory Failure

"High-flow nasal cannula device was utilized. Humidifier temperature was set at 37°C via large-bore bi-nasal prongs, and inspired oxygen (FiO2) was adjusted to maintain oxygen saturation by pulse oximetry (SpO2) ≥ 90%.The flow was initially set at 10 L/min and titrated upward in 5 L/min steps until patients experienced discomfort.~Patient will be evaluated every 8 hours and discontinued the device for eating, drinking and coughing up secretion and returned back to the device for 72 hours."

Patients initiated NIV; Inspiratory positive airway pressure (IPAP) was initiated at 10-12 cmH2O, and expiratory positive airway pressure (EPAP) started at 4-5 cmH2O. FIO2 was adjusted to maintain SpO2 ≥ 90%. The same protocol as done in HFNC, patient will be evaluated every 8 hours and discontinued the device and returned back to the device for re- evaluation within 72 hours
