Figure.. Respiratory Parameters in the Individual Patients Before, During, and After Noninvasive Ventilation in the Prone Position
The graphs represent trends of respiratory parameters in the individual patient at the 3 time points. Before pronation: immediately before initiating noninvasive ventilation (NIV) while the patient was still in the supine position. During pronation: after 1 hour of receiving NIV treatment while the patient was in the prone position. After pronation: 1 hour after NIV treatment stopped when the patient was in the supine position. A, Peripheral oxygen saturation (Spo2), P < .001 between before and during pronation, P < .004 between before and after pronation. B, Arterial partial pressure of oxygen (Pao2) to inspired oxygen fraction (Fio2), P < .001 between before and during pronation, P < .004 between before and after pronation. C, Respiratory rate P < .001 between before and during pronation, P < .001 between before and after pronation.
