1. A 2-min recording showing periodic breathing, stable delivered pressure, and fluctuating oxygen saturation in a premature neonate supported by nasal intermittent mandatory ventilation (IMV) with a set peak inspiratory pressure of 20 cm H2O and a respiratory rate of 20 inflations per minute.
A 2-min recording showing periodic breathing, stable delivered pressure, and fluctuating oxygen saturation in a premature neonate supported by nasal intermittent mandatory ventilation (IMV) with a set peak inspiratory pressure of 20 cm H2O and a respiratory rate of 20 inflations per minute. The loss of end-expiratory lung volume, denoted by the decrease in the respiratory impedance pneumography (RIP) sum trace at the onset of apnea suggests central apnea with an open glottis. Based on the absence of chest-wall excursions during apnea, nasal IMV did not sufficiently augment tidal volume, despite the use of a chin strap. (Adapted from Reference 37, with permission.)‏
