Spirometry Flashcards
Define and abreviate Spirometry, Vital Capicity, Forced Expiratory Volume in 1 Second, Peak Flow. Select information required to calculate the predicted values. Explain procedure for preforming spirometry.
Measures the amount of air exhaled and how long it takes to exhale.
Spirometry
When a person takes in as deep a breath as possible and exhales as much air as can possibly be squeezed out.
- total amount of air.
Vital Capacity
VC
Vital Capicity
FVC
Forced Vital Capacity
When the patient exhales forcefully, as hard and as fast as they can.
Forced Vital Capacity
PF
Peak Flow
The flow rate at the moment that the air is going fastest during exhalation
Peak Flow
MMEF
Mid-Maximal Expiratory Flow Rate
The rate of flow during expiration betweenthe first 1/4 and the last 1/4 of air exhaled.
Mid-Maximal Expiratory Flow Rate
What are the factors that determine the predicted values
Race
Age
Sex
Height
When instructing a patient with proper placement of the mouth piece, what instructions are you going to give?
- Behind the teeth
- On top of the tongue
When obeserving the patient what are you looking for?
- Air escaping the nose?
- Mouth piece being used properly?
- Is the patient working hard?
- Did the patient take in a deep breath before exhaling?
- Cheek Action
How many efforts are required for a valid spirometry test?
3
Each effort much be with in what percentage of the others to be considered valid?
5%
In order for the FVC to be considered within normal limits it has to be within what percent of the predicted values?
20%
