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

Efficacy of a New Full Face Mask for Noninvasive Positive Pressure Ventilation: CommentIn addition, there are two small bore orifices in the superior aspect of the mask to act as exhalation valves. In patients discharged home from the hospital with the mask, oxygen was administered by a compressed gas source to ensure gas flow if electrical failure would occur.

Moreover, all masks were equipped with quick release straps to ensure immediate removal if needed. All of our patients were awake and alert, were able to provide their own self-care, and were knowledgeable about the benefits and potential hazards of using a TFM. We followed the above-stated recommendations and found in all patients while using this mask a reduction in the sense of dyspnea, a lowering in the arterial carbon dioxide, and an improvement in their functional status. No complications during short- or long-term use at home were observed in our patients, and the above recommendations for use are strongly encouraged asthma inhalers.

Other complications such as eye irritation and gastric distention would be expected to be more common during noninvasive ventilation with the TFM. However, eye irritation and gastric distention were not observed in any subject and may further reflect an improvement in patient ventilator synchrony with the use of a more comfortable mask.
Although NPPV via N, oral, or NO routes has been shown to be effective in improving ventilatory status in patients with acute or chronic respiratory failure, these therapies are limited by being labor intensive. When noninvasive ventilation is applied to critically ill patients with acute respiratory failure, mask leaks, patient communication, and patient comfort necessitate constant nursing and/or respiratory therapy intervention for mask repositioning and patient monitoring.

Chevrolet and colleagues reported that patients with COPD receiving NPPV required 90 to 100 percent of one ICU nurse’s time to provide emotional support, give direct personal care, and adjust the face mask. These constant demands on nursing care and mask repositioning limit the broad application of this technique for patients in acute respiratory failure. A face mask that is more comfortable for the patient but requires less adjustment to minimize mask or mouth leaks could substantially reduce the labor intensiveness of NPPV.
