Pulmonary Function test

Question 1

A noninvasive test that provide measurable feedback about the function of the lungs.

Answer 1

Pulmunary Function test

Question 2

PFT can diagnose lung disease, measure the severity of the lung problems, check to see how well treatment for a lung disease is working.

Answer 2

True

Question 3

Answer 3

Tidal volume (VT) (500ml)

Question 4

Answer 4

Ispiratory reserve volume (IRV) (3100 ml)

Question 5

Maximum volume of air taht can be exhaled from the resting end-expiratory level. Ilang ml?

Answer 5

Expiratory Reserve Volume (ERV) (1200 ml)

Question 6

Answer 6

Residual volume (RV) (1200ml)

Question 7

Maximum amount of air taht can be inhaled from the normal exhalation. Ilang ml?

Answer 7

Inspiratory Capacity (IC) (IC=VT+IRV) 3600ml

Question 8

Amount of air that remains in the lungs after a resting tidal exhalation. Ilang ml?

Answer 8

Functional residual capacity (FRC) (FRC=ERV+RV) 2400ml

Question 9

Maximum amount of air that can be exhaled after a maximal inhalation. Ilang ml?

Answer 9

Vital capacity (VC) (VC=IRV+VT+ERV) 4800ml

Question 10

Answer 10

Total Lung Capacity (TLC) (TLC=IRC+VT+ERV+RV) or (TLC=IC+FRC) 6000ml

Question 11

Doctor may order this tests if

Answer 11

Question 14

The most commonly prescribed pulmonary function test. It measures the amount of air that you can breath in and out and how quickly you exhale air.

Answer 14

Spirometry

Question 15

This test is used to assess the amount of air that is actually inhaled and the amount of air that remains in the lungs after exhalation.

Answer 15

Body Plethysmography

Question 16

This test measures how well oxygen is transported from the lungs to your bloodstream.

Answer 16

Lung diffusion capacity

Question 17

This test measures both lungs and heart function.

Answer 17

Cardiopulmonary exercise stress test

Question 18

Measures the severity of a lung disease by requiring the patient to inhale a medication that increases narrowing of the airway.

Answer 18

Bronchial provocation test
