Official Title: Prospective Study on the Possible Effects of High-Flow Heated and Humidified Nasal Oxygen Therapy (HFNO) on Gastric Distension
Brief Summary: High Flow Heated and Humidified Nasal Oxygen therapy (HFNO) has been increasingly used in emergency medicine to assist patients with short term respiratory failure and to provide adequate oxygen to the body prior to intubation. Gastric distension which is the bloating of the stomach due to air being pumped into it is a concern for anesthesiologists as it increases the risk of nausea and vomiting during surgery (aspiration). The objective of this study is use an ultrasound machine to measure the volume of fluid in the stomach before and after HFNO is used in a standard clinical manner.
