Changing gas flow during neonatal resuscitation: A manikin study

Abstract

Introduction: When using a T-piece device, resuscitators may try to improve airway pressures by increasing gas flow instead of correcting face mask position. Aim: To measure the effects of changing gas flow during positive pressure ventilation (PPV) on peak inspiratory pressure (PIP), positive end expiratory pressure (PEEP), expiratory tidal volume (V Te) and mask leak. Methods: Using a Neopuff T-piece device, 20 neonatal staff members delivered PPV to a modified, leak-free manikin. Resuscitation parameters were recorded. Study A: PPV for 4min at PIP 30cm H 2O and PEEP 5cm H 2O. Each minute gas flow was increased (5, 8, 10, and 15L/min). PIP and PEEP settings were unchanged. Study B: same pr..
