Respiratory Physiology Lab Flashcards
Respiratory Rate (RR)
Breaths/min
Inspiratory Reserve Volume (IRV)
Maximum volume of air that can be inhaled after a normal respiration
Expiratory Reserve Volume (ERV)
Maximal volume of air that can be expelled from the lungs after normal respiration.
Residual Volume (RV)
The amount of air that remains in the lungs after exhaling, can only be predicted, not measured.
Inspiratory Capacity (IC)
IC= VT + IRV . The amount of air that can be inhaled after a normal expiration
Expiratory Capacity (EC)
EC= VT + ERV .
Vital Capacity (VC)
Maximum amount of air a person can expel from the lungs after a maximum inhalation.
Functional Residual Capacity (FRC)
The volume of air present in the lungs at the end of passive expiration.
Forced Vital Capacity (FVC)
The amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.
Forced Expired Volume in one second (FEV1)
The amount of air you can forcefully blow out of your lungs in one second. Important measurement in people with diseased lungs because it shows lung capacity. (also a way to assess airway resistance).
Lung Volumes and capacities (lab procedure)
Examined the respiratory cycle and measured changes in flow and volume.
Pulmonary Function Tests (lab procedure)
Measured parameters of forced expiration that are used in evaluating pulmonary function.
Simulating an airway restriction (lab procedure)
Simulated an airway restriction
Purpose of LabTutor
displays data graphically and enables data analysis.
Spirometry
Measuring of breath. Common in pulmonary function test. Measures volume, flow (rate) , assesses state of lungs and airways (fibrosis, COPD)
