Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
To gentle inflate an infants lung the clinical team put a face mask around your baby's mouth and nose. The clinical team tries to achieve a good seal between the face and the mask. A problem of mask ventilation is that air can escape between the mask and the face (what we call mask leak). Currently, two different types of facemasks ("Laerdal mask" or "Fisher \& Paykel mask") are routinely used in the delivery room at The Royal Alexandra Hospital.
The purpose of this study is to find out if one facemask is leaking less between the face and the mask.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
