This disclosure relates to systems and methods for monitoring sedated patients that are receiving supplemental oxygen flows. A method of monitoring a patient's breathing while sedated includes identifying an end expiratory pause in the patient's breathing pattern and obtaining a first respiratory signal corresponding to a nasal pressure of a patient. The method may also include delivering a pulse of high-flow oxygen during the end expiratory pause at a rate of about 30 liters-per-minute (L / min) and delivering the pulse of high-flow oxygen during the end expiratory pause for less than 0.5 seconds. The method may further include measuring a peak nasal pressure and a peak oxygen flow and synthesizing a second respiratory signal. The second respiratory signal may correspond to the peak nasal pressure and the peak oxygen flow, and may be normalized for the patient. The method may additionally include determining the patient's breathing pattern, rate, or frequency.

An extracorporeal membrane oxygenation (ECMO) system for infusing blood with oxygen and for removing carbon dioxide from blood includes an outlet from the oxygen line to share oxygen from the oxygen source as between the system and a nasal cannula or other supplemental oxygen device. The ECMO system may alternatively or in addition capture oxygen-rich exhaust as a by-product of the process. This captured oxygen-rich exhaust would be recycled and shared with a nasal cannula or other supplemental oxygen device. The recycled oxygen-rich exhaust is not only richer in oxygen than air, but also warm and moist which may benefit patients beyond cold and dry oxygen from a direct oxygen source.
