Anesthesia Machines Quiz! MCQ Trivia

Anaesthesia machines quiz MCQ trivia! These machines are also called the anaesthesia workstations and borrow from the foundations made by Henry Boyle. These machines have the ability to induce sleep where a patient or animal will not feel any pain as they undergo surgical procedures. How good are you when it comes to using these machines on patients and solving some of the issues they have? This quiz will help you find out!
