40-50 psi

pipeline inlet, pressure gauges

Question 8

Free Floating Valves

Answer 8

prevents leaks, moves in direction of flow

found in hanger yoke system

Question 9

Ball & Spring Valves

Answer 9

like oxygen flush valve

Question 10

Oxygen Flush Valve

Answer 10

“oh shit” valve
delivers oxygen at 35-75 L/min
risk for barotrauma

Question 11

Diaphragm Valve

Answer 11

1st stage regulator

2nd stage regulator

Question 12

Low Pressure System

Answer 12

16 psi

flow meter tube, vaporizers

Question 13

Proportioning Systems

Answer 13

prevent hypoxic delivery of gases

Question 14

Copper Kettle

Answer 14

most basic vaporizer, not still in use

Question 15

Open System

Answer 15

no mask on face

limited use, good for peds

Question 16

Semi-Open System

Answer 16

mask on face (mapelson)
room air and anesthetic
carbon dioxide will accumulate under mask
ex.) bain circuit

Question 17

Pethick’s Test

Answer 17

Tests bain circuit
if bag deflates –> inner tubing intact (valsalva)
if bag inflates –> inner tube damaged

Question 18

Semi-Closed System

Answer 18

mask on face
no room air inspired
has pop off valve
>20cm = override esophageal sphincter

Question 19

Closed System

Answer 19

rebreathing of all gases

Question 20

Degredation of inhaled anesthetics produces

Answer 20

compound A
carbon monoxide
fire & extreme heat

Question 21

Hydrophobic HME

Answer 21

membrane

Question 22

Hygroscopic HME

Answer 22

foam
wet –> may increase resistance
overall more effective of the HME’s

Question 23

VCV

Answer 23

Volume Controlled Ventilation
constant volume
pressure changes
good for paralyzed with good compliance

Question 24

PCV

Answer 24

Pressure Controlled Ventillation
constant inspiratory pressure
variable volume delivery

Question 25

PSV

Answer 25

Pressure Support Ventilation
detects inspiratory effort and augments spontaneous breaths
-can also set expiratory PEEP

Question 26

SIMV

Answer 26

Synchronized Intermittent Mandatory Ventilation

VCV or PCV + PSV
