Anesthesia gas
Terms
undefined, object
copy deck
- inorder for the vaporizer to work
- oxygen flowmeter must be on
- direct, indirect
- types of vaporizers
- one way valve
- inhalation flutter valve/tubing and exhalation flutter valve/tubing
- a green tank/white, compressed gas, has a pin index and pressure gauge
- oxygen tank
- 13 #
- empty tank weighs
- a breathing circuit that constantly reuses oxygen and anesthetic gas, removes carbon dioxide ad recycles exhaled gases
- rebreathing (circle systems)
- If oxygen flow rate too low, oxygen tank empty, reservoir bag too small, pop off valve open too much then
- under filled bag
- on top of CO2 absorber, indicates pressure in airways and lungs
- pressure manometer
- 5 #
- weigt f liquid/gas component
- psi x .3 =
- # liters of oxygen in tank
- has a level window, fill port, measures the % of anesthesia gas mixed with the oxygen as it passes out
- vaporizer
- prevents atelectasis, flushes out CO2, use CPR, perform every 5 min during long procedures
- bagging patient
- liquid--> vapor
- oxygen flows by it
- If oxygen flow rate too high, or reservoir bag is too large, or pop off valve is not open enough then
- bag is over filled
- 100-200 psi
- this is when you change oxygen tanks
- contains soda lime, has a moisture relief valve
- carbon dioxide absorber cannister
- disposes exhaled gases
- scavenger
- allows oxygen to by-pass vaporizer, oxygen goes to rebreathing bag then to the patient
- oxygen flush valve
- 18 #
- full tank weighs
- endotracheal tube cuff not inflated properly, endotrach tube too small in diameter, tube not in trachea
- decreased movement of bag
- this indicates how many liters/minutes of oxygen are flowing to the animal
- oxygen flowmeter
- removes carbon dioxide
- absorber canister
- < 500 psi
- change nitrous oxide tank
- breathing circuit that doesn't rebreath gases (made for patients <15 #
- non-rebreathing
- used so only the correct sized cylinder will ft into the yoke
- pin indexed
- store and delivers oxygen, vaporizes liquid anesthesia and mixes wiht oxygen, and removes exhaled gases
- functions of the anesthesia gas machine
- very precise, adjusts for oxygen flowrate, fewer mistakes. (out of circuit)
- Direct vaporizer
- indicates the psi present in a tank
- pressure gauge
- causes injury to lung alveoli
- over fill of bag
- allows waste gases to leave the system and enter the scavenger system
- pop off valve
- soda lime + carbone dioxide =
- heat and color change to purple
- tubing that connects to the endotracheal tube
- Y-piece
- capacity of 1-2 liters, stores gases, easier to breathe from reservoir, allows patient to be bagged, and respiratory monitoring
- reservoir bag
- full oxygen tank has how many liters
- 2200 psi x .3 = 660 liters
- 2200 psi
- "E" cylinder holds-
- a blue tank, not seen often, pressure gauge measures gas portion not liquid portion
- nitrous oxide tank
- non-rebreathing, rebreathing
- 2 types of breathing circuits are
- gives pressure relief to the system, allows waste gases to leave the system and enter the scavenger system, close to bag animal; then reopen
- pop off valve
