Lecture 4C Flashcards
What 3 things can a diagnostic spirometry help do?
- Distinguish between different types of lung diseases
- Determine the severity of functional impairment
- Monitor the treatment of a lung disorder
What is Diagnostic Spirometry?
A tool for the measurement of the breathing capacity of the lungs
What is Incentive Spirometry?
A method of encouraging voluntary deep breathing by providing visual feedback about inspiratory volume
Incentive Spirometry reduces what risks?
- Atelectasis
2. Pulmonary consolidation
What is the tidal volume?
The amount of air that moves into and out of the airways with each inspiration and expiration during normal quiet breathing
- Usually around 500 mL
What is minute ventilation
Total volume of air taken in by the body during 1 minute
MV=TV x RR
What is the Anatomical Dead Space?
The portion of the tidal volume that remains in the nose, pharynx, larynx, trachea, bronchi and terminal bronchioles
- The portion of air that does not participate in gas exchange
What is Alveolar Ventilation
Total volume of air that reaches the sites of gas exchange during 1 minute
AV = (TV-ADS) x RR
What is Inspiratory Reserve volume
Amount of air you can inspire above your normal tidal volume
What is Expiratory Reserve Volume?
The amount of air you can expire above your normal tidal volume
What is the Residual Volume?
The amount of air the remains in the respiratory system after a forced expiration
What is the Functional Residual Capacity
the sum of the residual volume and expiratory reserve volume
What is Inspiratory Capacity
The sum of the tidal volume and IRV
What is the vital capacity?
The sum of tidal volume, IRV, and ERV
