Noninvasive positive pressure ventilation, also called noninvasive ventilation (NIV), is delivered through a noninvasive device, such as a full-face mask. Unlike the systems for invasive ventilation, which is delivered through an endotracheal or tracheostomy tube, the NIV delivery system is not a closed system, and so it leaks. The size of the leak affects the tidal volume delivered and the ability of the patient to trigger the machine into inspiration or cycle the machine into expiration. The acceptable leak for most systems is less than 35% of the peak inspiratory flow (leakage may be expressed as a percentage or as liters per minute).

Objective: Discomfort and noncompliance with noninvasive ventilation (NIV) interfaces are obstacles to NIV success. Total face masks (TFMs) are considered to be a very comfortable NIV interface. However, due to their large internal volume and consequent increased CO2 rebreathing, their orifices allow proximal leaks to enhance CO2 elimination. The ventilators used in the ICU might not adequately compensate for such leakage. In this study, we attempted to determine whether ICU ventilators in NIV mode are suitable for use with a leaky TFM. Methods: This was a bench study carried out in a university research laboratory. Eight ICU ventilators equipped with NIV mode and one NIV ventilator were connected to a TFM with major leaks. All were tested at two positive end-expiratory pressure (PEEP) levels and three pressure support levels. The variables analyzed were ventilation trigger, cycling off, total leak, and pressurization. Results: Of the eight ICU ventilators tested, four did not work (autotriggering or inappropriate turning off due to misdetection of disconnection); three worked with some problems (low PEEP or high cycling delay); and one worked properly. Conclusions: The majority of the ICU ventilators tested were not suitable for NIV with a leaky TFM.
