In the presence of a high-flow device, what should be checked if a patient is showing signs of hypoxia?

When a patient shows signs of hypoxia while using a high-flow device, checking the oxygen source pressure is critical. High-flow devices deliver a precise amount of oxygen to the patient and function optimally when the source pressure is sufficient. If the source pressure is inadequate, the device may not deliver the required flow of oxygen, potentially leading to hypoxia.

Ensuring the oxygen source pressure is adequate confirms that the high-flow device can perform effectively and meet the patient's oxygen needs. Low pressure might indicate an issue with the oxygen supply, such as an empty tank or malfunctioning equipment, which would hinder oxygen delivery and could directly cause or worsen hypoxia.

While other factors such as the ventilator battery status, the patient's breathing pattern, and the fit and seal of the mask are important in managing a patient's respiratory needs, they are secondary to ensuring that there is an adequate source of oxygen pressure when hypoxia presents itself in a high-flow device context. If the source pressure is inadequate, correcting that issue takes precedence before addressing other potential problems.
