Advanced Respiratory Volumes and Capacities Quiz

Sample Question
What are 3 lung volumes that can't be measured by spirometry?

*These are RV(Residual Volume),FRC(Functional Residual capacity),TLC(Total Lung capacity).Key to understand all of these is understanding of WHY RV can't be measured and that is pretty simple, because Spirmotery measures how much air you can EXhale/INhale and how fast this processes can carry out, however it can NEVER exactly tell how much air is LEFT inside the lungs and remember that Residual Volume is the amount of air left in the lungs after MAXIMAL expiration.*Then just remember that RV is a component of FRC and TLC, or break down them too and it will make sense, look FRC is basically how much air is left int he lung after NORMAL expiration.(So basically residual volume that is there even with MAXIMAL expiratio+ Amount of air that can be breathed out AFTER Normal expiration which is known as ERV, so remember FRC=RV+ERV) , TLC basically is amount of gas in Lungs after MAXIMAL INspiration and involves RV,ERV,IRV(How much air you can breath in after NORMAL inspiration),TV(air that moves in to the lungs with quiet inspiration), so as you see TLC involves RV, so it is obvious that you can't calculate it with spirometry....Also you can think of TLC as The sum of FRC(RV+ERV) and Inspiratory Capacity(TV+IRV), because remember that TLC=RV+ERV+TV+IRV=FRC( same as:RV+ERV)+IC(same as :TV+IRV), so once again FRC can't be measured by spirometry thus TLC can't me measured by it either...FOR NOW at least Remember RV(Air in the lungs after MAXIMAL expiration),FRC(Volume of gas in the lungs after Normal expiration),TLC(Volume of gas in lungs after Maximal Inspiration) can NOT be measured by spirometry...
