PISS is at the
cylinder valves (pin index safety system)
what does the check valve of the hanger yoke do
minimizes transfilling (unidirectional flow)
what pressure system are ventilator power inlet in
int
what pressure system are pipeline inlet in?
int
what pressure system are pressure gauges in
int
what pressure system are flow meter valves
int
what pressure system are oxygen pressure-failure devices
int
what pressure system are oxygen second state regulator
int
what pressure system is the oxygen flush valve in
int
5 tasks of oxygen in the AGM
proceeds to the fresh gas flowmeters, piers the oxygen flush, activates the fail safe device, activates oxygen low-pressure alarm, compresses the bellows of mechanical ventilators
what kind of valve is the O2 flush valve
ball and spring
what does the first stage regulator do
high system to int. cylinder pressure decreased to 40-50 PSI
what does the second stage regulator do
intermediate to low. 40-50 to 16.
what kind of valves are the regulators
diaphragm
First and Second stage regulators that reduce the pressure from high to intermediate to low
what system are flow meter tubes in
low
what system are vaporizers in
low
what system are check valves in
low
valve between vaporizers and common gas outlet
what system is the common gas outlet in
low
hypoxic guard
nitrous oxide/ oxygen porportioning system
thorpe tube has the largest diameter at the
top
where is the free floating valves found
DISS and hanger yoke systems
free floating valve opens with
pressure, and closes with pressure
variable bypass vaporizers
one part goes thru system, some o2 goes thru without picking up gas
what happens if the inspiratory valve sticks open
the exp volume will exhaust thru the insp limb and ETCO2 will be elevated. pt is rebreathing CO2
what happens if exp valve sticks open
patient gets lower tidal volumes , hypoxic. due to the path of least resistance, the inspired volume will not enter the ETT but instead will bypass and exhaust the exp limb
tightening the APL valve will ____ the pressure
increase
APL valve function
adjusts the limit of pressure in the pt circuit and rebreathing bag
do the fail safes check pressure or flow
pressure. if theres a pipeline crossover the pt can get the wrong gas
(ball and spring valve?)
oxygen pressure failure device
shuts off and or porportionately reduces n20 flow if o2 pressure drops below 20
hypoxia prevention safety device
proportioning device, prevents you from setting a hypoxic mixture with the flow control valves. limits n20 flow to 3 times o2 flow.
Th oxygen flush valve delivers oxygen to pt at ____L/min
35-75L/min
may cause barotrauma
(pressurized at 40-50 PSI)
