|
Give the basic definition of "anesthesia"
|
Lack of sensation
|
|
List the anesthesia triad
|
Unconsciousness
analgesia muscle relaxation |
|
List the 6 essential parts of an anesthetic machine
|
Carrier gas source
pressure regulator flow meter oxygen flush valve vaporizer mounting bracket common gas outlet |
|
The oxygen flush vale releases a high flow of gas bypassing the vaporizer, how much does it release
|
35-75 L/min (varies by machine)
|
|
List the 3 carrier gases
|
Oxygen
mix of oxygen and nitrous oxide (entonox) medical air |
|
List the two main differences between the cylinders which N2O (nitrous oxide) and O2 (oxygen) are stored
|
N2O contains liquid and gas and the gauge does NOT indicate the volume left
O2 contains only gas phase and the gauge does indicate volume left |
|
List the 4 main safety features in an anesthetic machine
|
Color coding and labeling
pin index safety system Non-Interchangeable screw threat (NIST) Daimeter index safety system and quick connect (DISS) |
|
Describe and differentiate the High-Intermediate-Low pressure systems
|
High = from the cylinder (2000 psi) to the pressure regulator (50 psi)
Intermediate = pressure regulator (50psi) to the flow meter Low = flow meter to the patient / common gas outlet |
|
Describe what a "breathing system" is
|
A set of tubes connecting the patient to anesthetic machine
|
|
When on an anesthetic machine, a patients exhales gas will contain what
|
Oxygen
carbon dioxide anesthetic |
|
Describe the difference between an afferent and efferent reservoir system
|
It is determined by where the reservoir back is located; on either the afferent limb or the efferent limb
|
|
List the main types of a non-rebreathing system
|
Bain (Mapleson D)
Ayre's T Piece Jackson Rees (modification to the ayre's t piece) parallel lack and others... |
|
Which of these non-rebreathing systems can be used with anesthesia
|
All except the ayre's t piece - only used for ventilation with 100% oxygen
|
|
What is the ideal size of a reservoir bag
|
Big enough to hold 3-6 x the tidal volume
|
|
What is an APL / pop-off valve
What is air intake valve |
A valve build into the rebreathing system that limits pressure build up within the system and vents gas to the scavenging system
air intake valve allows air to draw in room air with no anesthetic |
