Abstract：It is well known that anesthesia machine is the most important life-support and first-aid equipment in the operation process.
To ensure the normal operation of anesthesia machine, we should not only understand its working principle and common troubleshooting
methods, but also do related preventive maintenance. The working principle and basic structure of Ohmeda 7100 anesthesia
machine were described in this paper. Then the preventive maintenance methods of medical equipment were summarized by analyzing
the causes of failure alarm such as low tide volume, high tide volume, and leakage of patient loop, which could provide some
reference for the peer maintenance.
