Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure VentilationNoninvasive positive pressure ventilation (NPPV) has been shown to be an effective modality for the treatment of chronic respiratory failure in patients with severe restrictive ventilatory disorders’ and in selected patients with chronic obstructive pulmonary diseases.

In addition, several recent studies have shown that NPPV may be an effective treatment for acute respiratory failure. In some patients, however, NPPV has limited efficacy because of significant problems with mask or mouth leaks, the development of facial pressure sores related to the mask, and feelings of claustrophobia.’ Moreover, the requirement for frequent nurse and respiratory therapist intervention to adjust the mask so as to prevent excessive leaking, or ensure patient comfort, limits the application of NPPV in treating patients with acute respiratory failure so.

Recently, we have had the opportunity to use a new prototypical type of face mask (Total face mask, Respironics, Monroeville, Pa) that covers the whole anterior surface of the face and delivers effective ventilation via the nasal and oral routes. This mask has a more extensive patient-mask interface and does not obstruct the patient’s field of vision.

Our purpose in this study was to compare the short-term effect of NPPV delivered via this total face mask (TFM) to nasal (N) and nasal-oral (NO) masks, on ventilatory variables, gas exchange, dyspnea, mouth and mask leaks, and patient comfort with the mask. In addition, we wanted to determine the long-term efficacy of daily nocturnal NPPV via the TFM on gas exchange and functional status after several weeks.

Herein, we discuss the effectiveness of NPPV with this TFM in the treatment of patients with chronic respiratory failure. All patients were admitted to the Ventilator Rehabilitation Unit at Temple University Hospital, Philadelphia, for evaluation and treatment of chronic respiratory failure. This noninvasive respiratory care unit evaluates patients for noninvasive mechanical ventilation, instructs patients in the use of respiratory equipment, provides whole body and respiratory muscle reconditioning, and coordinates continuing outpatient follow-up.
