ANESTHESIA MACHINE VIDEO- PRINCIPLES: TEST 1
Patients undergoing general anesthesia are connected to an anesthesia machine for
what 2 purposes? - Answer -1) The delivery of Anesthetic Gases
2) Subsequent ventilation
Who's responsibility is it ensure proper functioning of anesthesia equipment in an
attempt to prevent injury and/or death and ensure maximum safety for the patient? -
Answer -The CRNA
Studies revealed that ______% of equipment problems involved the anesthesia
machine & breathing circuit, with failure to perform a pre-anesthetic check between
cases being the most common associated factor. - Answer -31%
What is the most effective prevention measure, that a CRNA can perform, which has
proven useful in detecting machine malfunctions? - Answer -A pre-operative prevention
checklist
T or F:
It is imperative that the CRNA understands and performs a daily anesthesia machine
check off in order to provide a safe and effective anesthetic. - Answer -True
The first thing a CRNA must do upon entering a room is check to make sure there is
proper emergency equipment available. What are these 2 items? - Answer -Emergency
equipment available: This includes an ambu bag and auxillary backup oxygen supply
that is not attached to the machine.
When should back-up auxiliary O2 supply be checked? - Answer -Daily
How much pressure should an O2 auxiliary tank contain? - Answer -1000 psi
If you are performing your auxiliary O2 tank check, as part of your anesthesia machine
check, at what psi should the tank be replaced? - Answer -Anything less than 1000 psi
After checking your proper emergency equipment what does the CRNA do next? -
Answer -Turn on the power to the anesthesia machine to see if it has power.
How long does the battery backup on an Anesthesia Machine last? - Answer -30
minutes in the event of a total power failure.
To make sure the battery backup alarm for the anesthesia machine is working properly
what does the CRNA do? - Answer -Dis-connect the machine from it's AC power
source which should be plugged into a red outlet.
Once the CRNA disconnects the anesthesia machine from AC power source what 2
things should they verify? - Answer -1) Visual verification of alarm
, 2) Auditory, that the machine alarms- This alarm is a high priority alarm
When battery back up is depleted, what 2 items discontinue on the machine delivery
system? - Answer -1) Volatile agent
2) N2O
What is essential to patient safety according to the ASA, AANA, APSF, & JACHO? -
Answer -An audible alarm on the Anesthesia Machine
The Anesthesia machine is divided into 3 pressure systems? Name the 3 pressure
systems - Answer -1) High Pressure System
2) Intermediate Pressure System
3) Low Pressure System
The CRNA first starts with the High Pressure System (HPS). The HPS receives gas
from __ ____________ at variable pressures. - Answer -"E" Cylinders
What is the flow of gas through the HPS starting with the Cylinder? Name all 5 in order -
Answer -1) Gas Cylinder
2) Hanger Yolk with Pin Index Safety System (PISS)
3) Unidirectional Check Valve
4) Pressure Gauges
5) First Stage Regulator
The hanger yolk located on the back of the Anesthesia Machine houses what 2
components of the High Pressure System? - Answer -1) Pin Index Safety System
2) Unidirectional Check Valve
The Unidirectional check valve, is a free floating valve that opens & closes with
____________. - Answer -Pressure
What valve allows the passage of gases into the Anesthesia Machine? - Answer -The
Unidirectional Valve
Located on the back of the Anesthesia Machine, the CRNA uses a wrench to verify
what PSI reading on a Bourdon Gauge for the O2 cylinder? - Answer -1000 PSI of
greater
If the pressure reading on the Bourdon Gauge is less than 1000 psi, what should the
CRNA do? - Answer -Obtain a new tank
