Description
Supplemental oxygen is often given to awake, sedated patients in order to decrease the frequency and depth of oxygen desaturation caused by periods of respiratory depression and airway obstruction. The Anesthesia Patient Safety Foundation has expressed that postoperative opioid-induced respiratory depression remains a serious patient safety risk associated with significant adverse events. Operating room fires are another preventable adverse event associated with constant flow oxygen with approximately 100 operating room fires occurring per year. Patient discomfort is another concern associated with conventional supplemental oxygen delivery. We have developed an intelligent supplemental oxygen flowmeter that only gives oxygen at the start of inspiration and at low flows for a brief period during the expiratory pause. The prototype determines respiration rate (RR) and inspiratory effort by measuring intranasal pressure through a cannula port. In order to compare our device to conventional oxygen delivery, we designed a study comparing fire safety and patient comfort between conventional constant flow and intermittent pulsed flow.
