![]() #OXY MAXIMUM ACTION RAPID TREATMENT 3 IN 1 TREATMENT PADS TRIAL# ![]() HFNC washes out nasopharyngeal dead space, improves oxygenation, decreases the work of breathing and respiratory rate, generates a low level of positive airway pressure, and provides heated and humidified gas to promote secretion clearance. The HFNC can deliver a continuous flow of gas between 20 and 60 L/min and offers many physiologic advantages that other oxygen delivery systems do not. The high flow rate makes breathing more efficient because it washes out the dead space. Dead space does not participate in gas exchange and contains a high fraction of carbon dioxide and low fraction of oxygen that is normally re-breathed. ![]() When a patient is in distress, the wash out of dead space makes breathing more efficient because it significantly decreases the amount of re-breathed carbon dioxide and acts as a continuous reservoir of new gas. #OXY MAXIMUM ACTION RAPID TREATMENT 3 IN 1 TREATMENT PADS TRIAL#.
