Final answer:
If the anesthesia machine alarms hypoxic gas mixture, the next steps include manually ventilating the patient with 100 percent oxygen and troubleshooting the machine to identify the cause.
Step-by-step explanation:
If the anesthesia machine alarms that a hypoxic gas mixture is being delivered, there are several next steps to ensure patient safety. The first step is to disconnect the patient from the anesthesia machine and manually ventilate the patient using a bag-valve mask with 100 percent oxygen. This will provide the patient with the necessary oxygen and prevent further delivery of the hypoxic gas mixture. Additionally, the anesthesia professional should troubleshoot the machine to identify the cause of the hypoxic gas delivery, such as a malfunctioning oxygen flowmeter or a disconnected oxygen supply.
