Ventilatory Capacity Flashcards
A measure of the expansion of the lung
Lung compliance
The ratio of driving pressure to the rate of the airflow in the airways
Airway resistance
The energy expended to inhale and exhale a breathing gas
Work of breathing
What is the formula for minute volume?
Frequency(f) x Tidal Volume(VT)
You can measure minute volume by using what respiratory equipment
Respirometer
Normal value for miniute volume
5-10 lpm
What 3 things can be obtained from a respirometer
Minute volume, frequency, average tidal volume
What is the formular for finding the tidal volume
Minute volume/frequency
What two things can be used to minimize factors that effect readings
Lightweight spinning elements and Lubricant
Turbinometers are not effected by what 4 things
- Turbulence
- Gas composition
- Temperature
- Water Vapor
Turbinometers are not used to measure what two things
Forced Vital Capacity(FVC)
Peak Expiratory Flow Reserve(PEFR)
The minimal airflow needed to start turbine turning is
2-3 LPM
The maximum airflow not to be exceeded is how much LPM
200-300 LPM
