“Preventing complications in the application of Non-Invasive Ventilation” Noninvasive ventilation (NIV) is using a ventilator support without administering an invasive artificial airway (endotracheal tube or tracheostomy tube). Noninvasive ventilation is used as a replacement for invasive ventilation. Complications of noninvasive ventilation include; Facial and nasal pressure injury and sores. This occurs due to the result of tight mask seals used to attain adequate inspiratory volumes. Pressure can be minimized by intermittent application of noninvasive ventilation, Scheduling breaks (30-90 min) to minimize effects of mask pressure. This can be prevented by balancing strap tension to minimize mask leaks without excessive mask pressures and covering vulnerable areas (erythematous points of contact) with protective dressings. Gastric distension can occur also. This can be avoided by limiting peak inspiratory pressures to less than 25 cm water, nasogastric tubes can be placed but can worsen leaks from the mask. Nasogastric tube also bypasses the lower esophageal sphincter and permits reflux. Dry mucous membranes and thick secretions is another complication. This is seen in patients with extended use of noninvasive ventilation. To prevent this from occurring, humidification for noninvasive ventilation devices should be provided along with daily oral care. Another complication that occurs is aspiration of gastric contents, especially if emesis occurs during noninvasive ventilation. To avoid this complication noninvasive ventilation shouldn’t be administered in patients with ongoing emesis or hematemesis. Complications of both noninvasive and invasive ventilation are Barotrauma and Hypotension. In Barotrauma (there is significantly less risk with noninvasive ventilation), and there is Hypotension, related to positive intrathoracic pressure which can be supported with
