Pulmonology Overview Flashcards
What is a normal Tidal Volume?
500mL (Normal quiet breathing)
What is a normal Inspiratory Reserve Volume?
3,000mL (Max Insp. Vol)
What is a normal ERV?
1,200mL (Max Expiratory Vol)
What is the amount of air known as that can be inhaled after the end of normal inspiration?
Inspiratory Capacity
3,500mL (Tidal + IRV)
What is the amount of air in the lungs at the end of a tidal volume breath known as?
Functional Residual Capacity
2,400mL (ERV + RV)
What is the maximum amount of air exhaled known as after a maximum inhalation?
Vital Capacity
4,700mL (IC + ERV)
What is the approximate volume which is left in the lungs after a maximal inspiration?
Total Lung Capacity
6,000mL (Vital Capacity + Residual Vol)
How much Residual Volume is left behind after a forced expiration?
1,200mL
Cannot be measured by spirometry
During inspiration what does the diaphragm do?
Contracts and pushes abdominal contents downwards.
Which finger is the plexor and which is the pleximeter when conducting percussion?
Plexor is the striking finger
Pleximeter is the finger being struck
Crackles and rales are commonly heard with what clinical conditions?
(Popping sound)
Pneumonia
Atelectasis
Heart Failure
Ronchi are commonly heard/associated with what clinical conditions?
(Almost a snoring like-blocked sound)
Cystic Fibrosis
Pneumonia
COPD
What are soft, low pitched sounds commonly heard during inspiration?
Vesicular breath sounds (expiratory phase is shorter than inspiratory)
What are breath sounds heard equally during inspiration and expiration?
Bronchovesicular
What are breath sounds which are louder and higher pitched; with expiratory sounds lasting longer than inspiratory?
Bronchial (longer expiratory phase)
