what are the nurse's responsibilities for diagnostic test for respiratory functions?
- explain to pt. what is going to happen
- get pt ready for exam
- may need to hold meds
-
what are the types of pulmonary function test?
- tidal volume (TV)
- residual volume (RV)
- vital compacity (VC)
- Inspiratory compacity (IC)
- forced expiratory volume (FEV)

what is the tidal volume test
volume of air with each inspiration

what is the residual volume test?
also called reserve volume
volume of air remaining in the lungs at the end of maximum expiration
-
what does the vital compacity test tell?
volume of air that can be expelled after maximum inspiration
-
what does the inspiratory capacity test tell?
maximum volume of air inhaled after normal expirations
-
what does the forced expiratory volume tell?
volume of expelled within first second of vital compacity
