Monitoring Ventilation Flashcards
What measurement of ventilation measures gas flow? (2)
Heat dissipation (heated wire anemometer)
Pressure gradient (pneumotachometer)
What’s this?
heated wire anemometer
What are possible sites for the respirometer?
Between the inspiratory valve and absorber
Behind the HME
Pt port
Between the PEEP and expiratory valve
After the expiratory valve closest to the vent.
Where is it common practice to place the respirometer?
Positions A and B
exhalation limb upstream
downstream of the unidirectional valve
Where is it common to locate pressure flow sensors?
BOTH positions B and D
What is indicated by the arrow?
Decreased compliance
What is indicated here?
gas leak distal to the flow of the sensor
might be deflated cuff or poorly seated LMA
What kind of loop and vent setting?
Pressure-volume loop
Pressure control vent. setting
What kind of loop and vent setting?
Flow volume loop
Pressure control vent
What’s this?
R wave envelope
What type of tubing absorbs water vapor?
nafion
