ABSTRACT
A prototype facemask interface was developed to help improve patient comfort
during non-invasive positive pressure ventilation. The prototype design includes a
flexible fabric “skirt” which is attached to the frame of a standard facemask. The
interface adapts easily to the contours of the face and provides increased contact
area with the skin. The performance of the prototype facemask was compared to the
performance of a standard facemask using a manikin. Air pressure and volume
airflow through the masks were controlled. ...
