Anesthesia Machine
This part of the anesthesia machine removes CO₂ from the breathing circuit.
Soda lime canister
This is the first drawer you check and contains emergency medications.
The top drawer
This should always be placed under the patient’s head in the supine position.
headrest/foam donut
Before starting a case, you always perform this check to ensure your machine is functional.
machine leak test
This is the most commonly used inhalation agent for general anesthesia today
sevoflurane
This safety feature ensures oxygen is always the last gas to fail.
fail-safe system
This item in the cart is essential for securing an airway and comes in sizes from newborn to adult.
endotracheal tube
You place this monitor first because it gives an immediate vital sign
pulse oximeter
You should verify that oxygen flow is set at this minimum level during pre-anesthesia checks.
200–500 mL/min
This gas makes your voice sound funny and is sometimes called “laughing gas.”
nitrous oxide
These devices precisely control the concentration of anesthetic gases delivered to the patient.
vaporizers
These blades, usually found in the cart, come in straight and curved varieties
laryngoscope blades
This IV gauge is typically preferred for general anesthesia cases
18-gauge
The alarms you must always confirm are on before a case.
high-pressure and low-pressure alarms
This color corresponds to oxygen tanks in the U.S.
Green
This gauge tells you how much oxygen is left in the tank.
Pressure gauge
You should always ensure this suction device is set up and ready before induction
Yankauer
Before induction, you must confirm these two IV items are primed and ready.
IV tubing and fluids
This step involves confirming backup oxygen is available
checking the O₂ E-cylinder
This early anesthetic agent was discovered partly by accident during “ether frolics.”
diethyl ether
This system prevents the patient from rebreating exhaled gases by separating inhalation and exhalation pathways.
circle breathing system
This emergency tool in the cart can temporarily provide respirations if the anesthesia machine fails.
Ambu bag (BVM)
This pre-oxygenation time helps delay desaturation during apnea
3–5 minutes
Checking this device ensures proper delivery of fresh gas flow into the breathing circuit.
common gas outlet
The first public demonstration of anesthesia occurred in this year at Massachusetts General Hospital
1846
