Machine checkout Flashcards
review for Machine Midterm. This information is from ICP "Anesthesia Machine Checkout" powerpoint.
Why do we verify backup ventilation equipment is available and which step is this in our checkout?
if machine fails, AMBU bag is only way to continue positive pressure ventilation
Why do we check Oxygen cylinder supply
The Oxygen cylinder is your backup supply if the pipeline supply fails
Why do we turn the oxygen cylinder off immediately after turning it on
1, prevent silent depletion
2. set off low 02 alarm if pipeline fails
What pressure should the gauge read for central pipeline supply?
around 50 psi
In order to check the low pressure system (on machines that aren’t fully automated) what must we confirm?
that the machine is off (prevent a false positive leak)
how exactly does the low pressure leak check work?
creates vacuum to see if there are cracks in the flow meter tubes or vaporizers
what is the purpose of the hypoxid guard mechanism on the flow meters?
prevents Fi02 from becoming less that 25% when nitrogen is turned on
What is the purpose of calibrating the O2 sensor?
ability to monitor gas mixture O2 concentration being delivered. Prevent hypoxic scenarios
What is the purpose of circuit leak check?
confirm no leaks in the breathing circuit
How can you measure the amount of leak in the breathing circuit?
turn gas (O2 or air) on, increase until pressure gauge stops moving.
What pressure should you hold to test the circuit?
greater than 30 cmH20
Why do we test the ventilator system?
- ensure it works
2. insure inspiratory and expiratory valves work
What is the result of a stuck expiratory valve?
increase pressure in the patients lungs
What is the result of a stuck inspiratory valve?
increase pressure in the machine
