The Idea is to Answer this Question in Under 10 Seconds If u can do this then u r prepared Well in Pulmonary Physio.
A pulmonologist is testing a patient's lung volumes and capacities using simple spirometry.
Which of the following lung volumes or capacities cannot be measured directly using this technique?
A. Expiratory reserve volume
B. Functional residual capacity
C. Inspiratory reserve volume
D. Tidal volume
E. Vital capacity

& tatola lung capacity becuz it includes residual vol

The correct answer is B.
The functional residual capacity is the amount of air left in the lungs after a normal expiration. Because this volume cannot be expired in its entirety, it cannot be measured by spirometry. Essentially, lung volume that contains the residual volume, which is the amount of air remaining after maximal expiration (e.g., functional residual capacity and total lung capacity), cannot be measured by spirometry. These volumes can be determined using helium dilution techniques coupled with spirometry or body plethysmography.
The expiratory reserve volume (choice A) is the volume of air that can be expired after expiration of a tidal volume.
The inspiratory reserve volume (choice C) is the volume of air that can be inspired after inspiration of a tidal volume.
Tidal volume (choice D) is the amount of air inspired or expired with each normal breath.
Vital capacity (choice E) is the volume of air expired after a maximal inspiration.

ROFLMAO !!!!!!!!!!!!!!!!!!!
Buddy first of all go to the top of the thread I said Pulmonary Physio. Secondly believe me the people who have answered have already given the test and gotten their scores. Now you have answered it you will be pretty soon giving it also.
Cheer Mate.

In summary,
Residual Volume is the culprit here - cannot be measured by spirometry
and since RV is a part of Functional Residual Capacity and Total lung capacity - they cannot be measured too.
So get this by heart - 3 volumes cannot be measured by spirometry - RV, FRC and TLC
(will save time in exam)

God gave up on us long ago man!!! He is hyperventilating not knowing what to do with all these super-intelligent USMLE aspirants.
(just a joke! didn't mean to offend any pious ones out there, apologies if i did)

No.
Actually God is watching 2 of His beings going at it. The USMLE test makers, who make the test passing odds more tough and USMLE aspirants who give the test and beat the odds.
He is marveling at His Creation.
While Angel Gaberiel is saying "Boss you have created too many nerds here. They are losing the essence of living life"
The Devil responds " Well thats y i m there for. Party Time "
God ( in a very commanding voice). " Well, I know they can overcome the Odds I have given them. They are provided with everything they need. All they need to do is figure out how."
This is my take or attempt at humor..... Will try to make it funnier.
