To keep your patients safe, it's important to frequently test your veterinary anesthesia machine. Leaks in the system can result in an inadequate amount of oxygen or anesthetic reaching the patient, which can be dangerous. You'll also need to ensure that your machine is correctly removing carbon dioxide from the exhaled air before it's recirculated. This procedure should be done before every operation — it doesn't take long to test your machine.
Not being able to hear what people are saying to you is not only frustrating to you, but also to the people who have to keep repeating themselves. You may not even realize how much you are missing or how many times you say "I'm sorry, what?" You may think that people are talking softer or you were just not paying attention. If you find yourself turning up the volume on the television or radio, it might be time to consider that the problems you are having when conversing with others is your hearing.
