Pregunta 1
Respuesta
-
Tidal volume is the amount of air inhaled with a normal breath from the resting level - about 500 ml
-
IRV - The max amount of additional air that can be inhaled beyond the tidal volume
-
ERV - the max amount of air that can be exhaled following a normal exhalation from the resting level
-
Residual volume - the amount of air that remains after a normal expiration
-
1,2,3 are correct
-
all are correct
Pregunta 2

Pregunta 3
Pregunta

Pregunta 4
Pregunta
Regarding FRC all are true except
Respuesta
-
Is what remains after a normal breath
-
FRC can be measured by spirometry
-
FRC increases with age
-
FRC decreases with lying down
Pregunta 5
Pregunta
With age all of the following are true except?
Respuesta
-
Increased RV
-
Increased FRC
-
Increased VC
-
None of the above
Pregunta 6
Pregunta
Lying down decreases FRC, VC is unchanged because of increased IRV

Pregunta 14
Pregunta
Methacholine challenge test differentiates between bronchial asthma and the other obstructive lung diseases like chronic bronchitis and emphysema
Pregunta 15
Pregunta
All of the following are restrictive lung diseases except?
Respuesta
-
Intrinsic lung diseases like interstitial fibrosis of lung or pneumonia
-
Extrinsic lung diseases that mechanically compress the lungs and limit their expansion
-
Neuromuscular diseases of the respiratory muscles
-
none of the above
Pregunta 16
Respuesta
-
Can be measured by Gas dilution method

Or by body plethysmography
-
Gas dilution method under estimates trapped gas
-
if TLC pleth/TLC gas dilution is > 1,2 trapped gas is present
-
all of the above are correct
Pregunta 17
Pregunta
Diffusing capacity (Dl CO)
Respuesta
-
Decreased in emphysema (obstructive lung disease)
-
decreased in interstitial lung disease (restrictive lung disease)
-
Increased in asthma (obstructive lung disease) - due to increased blood flow to lung
-
used to distinguish between intrinsic lung disease from extrinsic lung disease
-
all of the above are correct
