Electronic vrs mechanical Flashcards
For a mechanical turbine respirometer do not turn off suddenly if flow exceeds
150 lpm
The flow range for a mechanical vein turbine respirometer is
3-300 lpm
If a mechanical respirometer reads 1.9 liters where is the liter needle and the milliliter needle
Liter needle almost at 2
Milliliter needle will be on 9
Respirometers are for inhalation or exhalation only
Exhalation
What is needed for a respirometer setup for a patient
one way valve
2 common methods to measure respiratory muscle strength
Vital capacity (VC)and
Negative inspiratory Force(NIV)
Pressure equals
Force/Unit area=pressure
What are the 3 devices to measure lung gas pressure
- Gravity dependent fluid manometers
- Mechanical aneroid manometers
- Electromechanical transducers
Pressure transducers are usually attached by tubing to what
the site where pressure is measured
For the tubing that attaches to a pressure transducer it should be what
As short and as rigid as possible
What pressure measuring device is most used in respiratory care
Mechanical aneroid Manometers
