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...
