Machine
The most common circuit disconnection site
What is the Y piece
Safer Bellow type
What is Ascending (standing) bellows are considered safer than descending (also known as hanging) bellows. In the event of a circuit disconnect, ascending bellows will fail to rise whereas descending bellows will continue to descend due to gravity and ascend during the inspiratory phase.
BONUS!!!!!!
Take your 100 points and choose another square! Yay you!
This test is performed by closing the pop-off valve, occluding the y-piece, and evaluating for a drop in pressure after pressurizing the circuit to 30 cm H2O using the flush valve.
What is the leak test
This Mapleson circuit is best for spontaneously ventilation
What is Mapleson A
This is a common cause of a vaporizer leak
What is a loose filler cap
Miller RD. Miller's Anesthesia. 8th ed. Philadelphia, PA: Elsevier Saunders; 2015:808.
During this time the oxygen flush valve is contraindicated
What is inspiration during mechanical ventilation
The o2 flush control valve at a rate of 35-75 L/min and 50 psig can cause barotrauma. It shouldn't be used when there is no outlet for excess gas pressure to escape. Avoid during inspiratory phase of mechanical ventilation when the inspiratory valve is open to the patient but there is no vent for gases to escape.
This is the result of a bellows leak in an oxygen driven ventilator
What is increased PIP & FiO2
These 2 alarms are triggered by a change in circuit pressure
What are the disconnect/low pressure alarm and high pressure alarm
100 grams of CO2 absorbant will eliminate this amount of CO2
What is 26 L
This is a danger of Desflurane and a desiccated CO2 absorber
What is carbon monoxide
This gas flowmeter is positioned last in the anesthesia machine
What is the O2 flowmeter
These items are eliminated from the circuit when in vent mode
What are the reservoir bag and APL valve
This test evaluates the anesthesia machine from the flow control valves to the common gas outlet
What is the low-pressure circuit leak test
This is the amount Scavenging systems limit halogenated agents in the OR to
What is 2 ppm
In a circle circuit, this determines the amount of gas that is rebreathed
What is the FGF rate
This safety mechanism exists on the pipeline inlet of the anesthesia machine
What is the diameter index safety system (DISS)- to prevent connection of a gas line to the wrong connector on the machine
In synchronized intermittent mandatory ventilation (SIMV), the CRNA is responsible for setting these
What are the Vt and RR
These components ensure gas can not reverse flow
What are unidirectional valves
This airway item is used to prevent dehydrated mucosa, altered ciliary function, dry/hard secretions, atelectasis and loss of body heat
What is a heat and moisture exchanger (HME)
Daily Double!
Circuit leak test
This is the only machine safety device downstream from the flowmeters
What is the oxygen monitor
The fail-safe valve, proportioning system, and the O2 supply alarm are upstream from the flowmeters.
This is the most effective way the CRNA can avoid a fire during sedation (MAC) for a surgery above the nipple line
What is Keep oxygen below 30%
In this mechanical ventilation mode, the CRNA controls the Vt and RR
What is volume control ventilation
The cylinder pressure gauge is this type of gauge
What is Bourdon gauge
