Use the following respiratory volumes to calculate the missing volumes. Tidal volume = 485 ml Inspiratory reserve volume = 3,110 ml Forced vital capacity = 4,672 ml Inspiratory capacity= Expiratory reserve volume = Minute respiratory volume (MRV) is the amount of air moved in and out of the lungs at rest during one minute. (It is similar to cardiac output which measures the amount of blood pumped in one minute). If the individual above has a breathing rate of 11 breaths per minute, what is his minute respiratory volume? ml/min The rest of this lab will focus on two individuals with respiratory problems. In diagnosing the patients you will be looking at: EVC total volume that can be forcefully expired from a maximum Inspiratory effort FEV Forced Expiratory Volume in One Second - this is the volume of air which can be forcibly exhaled from the lungs in the first second of a forced expiratory maneuver. It is expressed in liters. (You can see this illustrated on the chart on the first page.) FEV% (FEV:/FVC)- This number is the ratio of FEV; to FVC-it indicates what percentage of the total FVC was expelled from the lungs during the first second of forced exhalation.
