This suction mask (SM) reduced leak in a manikin model,3 but failed in some infants when tested in a clinical trial.4 We hypothesised that in these infants, leak around the SM allowed inspiratory flow to be diverted away from the airway opening towards the suction tubing.To test our hypothesis, we administered positive pressure ventilation with the SM in different positions, intentionally causing minimal and large leak. A modified baby manikin (Laerdal, Stavanger, Norway) was used3 with one flow sensor (FS1) between a Neopuff (Fisher & Paykel Healthcare, Auckland, New Zealand) and the SM and a second flow sensor (FS2) within the suction tubing (figure 1A).
