Step-by-step explanation:
The most common critical incidents in anesthesia are primarily due to medication errors, equipment failure, and anesthetic gas leaks. Medication errors can occur when the wrong drug is administered or the wrong dose is given. Equipment failure can include malfunctions or errors in the anesthesia machine, such as improper delivery of anesthetic gases or failure to monitor patient and machine parameters. Anesthetic gas leaks can pose a risk to both patients and healthcare professionals if they are exposed to high concentrations of the gas.
