Preoxygenation is critical prior to intubation, especially in the emergency department (ED), where this reservoir of oxygen can help mitigate unexpected hurdles encountered during intubation. There are a number of different techniques available for providing oxygen to patients before intubation, including non-rebreather masks and bag-valve-masks (BVMs), with or without concurrent use of a nasal cannula. To compare the effectiveness of these techniques, researchers measured fractional expired oxygen (FeO2) concentration in 30 healthy ED staff volunteers after 3 minutes of tidal volume breathing with an anesthesia circuit and with combinations of the devices, in random order.
Mean FeO2 levels achieved with the anesthesia circuit (81%) and with…
