- The primary goal of an anesthesia equipment quality assurance program
Show answer
Ensuring consistent, safe equipment function to prevent patient harm- A preventive maintenance schedule is designed to
Show answer
Service equipment at regular intervals to catch problems before they cause failure- A key component of an operating room fire safety protocol
Show answer
Managing the fire triangle by controlling oxidizers, ignition sources, and fuel- The three elements of the operating room fire triangle
Show answer
An oxidizer, an ignition source, and fuel- A common oxidizer contributing to operating room fires
Show answer
Supplemental oxygen or nitrous oxide- A common ignition source in operating room fires
Show answer
Electrocautery devices or lasers- Waste anesthetic gas (WAG) scavenging systems exist to
Show answer
Remove excess anesthetic gases from the operating room to protect staff from chronic exposure- OSHA-recommended exposure limits for waste anesthetic gases aim to reduce staff risk of
Show answer
Chronic occupational exposure effects, such as reproductive and neurologic concerns- A negative pressure leak test on the anesthesia machine checks for
Show answer
Leaks in the low-pressure system between the flow control valves and the common gas outlet- A pipeline gas supply pressure alarm typically triggers when pressure falls below
Show answer
Approximately 45 psi- Color coding for medical gas cylinders in the United States assigns which color to oxygen
Show answer
Green- The diameter index safety system (DISS) and pin index safety system exist to
Show answer
Prevent accidental connection of the wrong medical gas to equipment or cylinders- A key safety reason to check the oxygen fail-safe (pressure sensor shutoff) system
Show answer
It cuts off other gas flow if oxygen supply pressure drops, preventing delivery of a hypoxic mixture- The purpose of an oxygen analyzer on the anesthesia machine's inspiratory limb
Show answer
Continuously verifying the actual delivered oxygen concentration to prevent a hypoxic gas mixture- A root cause analysis after an anesthesia-related adverse event aims to
Show answer
Identify underlying system failures rather than assign individual blame, to prevent recurrence
