Human Performance 15 16:55 Lung Volumes Vital Capacity (VC) – volume of air expired > max inspiration Residual Lung Volume (RLV) – air remaining > max expiration Total Lung Capacity – TLC = VC+RLV. Ratio for a young person up to 30… is  80% 20% respectively. Height is the most important. Long capacity stays the same with old people. Diseases: Restrictivity.   Emphysema lower VC. Obstructive diseases  within 3 sec you get 90% of volume (normal value) someone with a disease it  would be less. COPD (Chronic Obstructive Pulmonary Disease)  Breathing and Volumes: V(e) (L/Min) = Tidal Volume(L/B) X RR (b/min)

Unformatted text preview: o At rest 10L/min. o Ex: if V(e)=10 and RR is 10 then TV is 1! o Ex: TV=.5 , RR = 20 Anatomical Dead Space (ADS) no gas exchange occurs in that area. o V(Change LV)=V(e)-(ADSXRR) o ADS~=1lb wt = 1ml DS Ex: Given V(e) 10 and ADS=.2 and RR=10 then 10-2=8, then 10-(.2X20), 10-4=6 o PDS=ADS+Unused Alveoli, for healthy people they PDS and ADS are the same. PDS>ADS, thats when people die. Maximal Exercise o V(e) = TV X RR, 50% of VC X 50b/m, lets VC=4 then predicting Nasal Expanders 16:55 16:55...
