Comparison of Two Round Face Masks During Neonatal Resuscitation

We will use a Laerdal round mask (Laerdal, Stavanger, Norway) compared to a Fisher & Paykel (FP) (Fisher & Paykel Healthcare, Auckland, New Zealand) 'round' neonatal resuscitation mask. The two point top hold for Laerdal 'round' mask and the rim hold for the Fisher & Paykel mask. A Respiratory Function Monitor will be placed between the face mask and the ventilation device. It uses a small (dead space 1 mL) flow sensor to measure gas flow in and out of a face mask. This signal is automatically integrated to provide inspired and expired tidal volume. The difference equals the leak from the face mask. It also calculates respiratory rate and minute ventilation, measures spontaneous inspirations and ventilation pressures. The signals of airway flow, tidal volumes, airway pressure, inspired oxygen concentration, temperature, blood pressure, oxygen saturation, heart rate will be digitised and recorded at 200Hz using the Spectra physiological recording program (a customised neonatal respiratory physiology program). We will compare the % of mask leak within the two face masks.
