Study Of The Use OfNoninvasive Positive Pressure Ventilation In Patients With Acute Respiratory Failure In Intensive Care Units

Abstract

Acute hpoxemic respiratory failure (AHRF) is characterized by severe hypoxemia that is relatively refractory to oxygen therapy, it results I from processes that cause alveolar collapse or filling. In contrast, acute ventilatory failure is characterized by the inability of a failing ventilatory pump to provide a level of alveolar ventilation sufficient to meet the required metabolic demands.

Mechanical ventilation has been successful 111 supporting ventilation 111 patients with acute respiratory failure, however, conventional intubation and mechanical ventilation are not optimal for patient comfort and ancillary care.

For purposes of improving comfort without physical and psychological trauma associated with tracheal intubation, ventilatory support can be administered through a tight-fitting nasal or full face mask "noninvasive positive pressure ventilation (NIPPY)". NIPPY is defined as the delivery of mechanically assisted breaths without placement of artificial airway such as endotracheal or tracheostomy tube.

The ann of the present study was to evaluate the effects of mask continuous positive airway pressure (CPAP) on gas exchange and breathing pattern in patients with ARF as an alternative to intubation and mechanical ventilation.
