Lung volumes
-RV – after max expiration
-ERV – breathable after nl expiration (amt left after nl expiration – RV)
-TV – in/out w/ nl breathing
-IRV – max inspiration – TV
-VC – all but RV (breathable)…ERV+TV+IRV
-FRC – after nl expiration…RV+ERV
-IC – max breath…IRV+TV
-TLC – lung vol…RV+ERV+TV+IRV
Phys dead space
Vt*(PaCO2-PeCO2)/PaCO2
Dissolved O2
PO2*solubility
PaO2 factors
PAO2 (and thus PCO2, PIO2), A-a gradient
O2 content
O2binding*Sat + dissolved O2(PaO2?)
O2binding
maximal of O2 bound to Hb at 100% sat
Sat
%heme-sites bound by O2 on a given Hb
Hypoxia/O2 delivery
CO*O2content
Alveolar gas equation
PAO2 = PIO2 – PACO2/R
Collapsing pressure
2T/r
Surfactant fxn
Increase compliance
↓tension (↓collapsing pressure of alveoli)
Major site of airway resistance
Medium bronchioles
Models of perfusion-limited vs. diffusion limited
perfusion-limited – equilibrates early (limited by any dead space)
-N2O
-O2
diffusion-limited – never equilibrates
-CO
-O2 during exercise
Why HbF  left shift
Does not bind 2,3 BPG as well
3 forms of CO2 in blood
Dissolved
Bound to Hb
HCO3
4 changes w/ Exercise
↑ Ventilation
↑Pulm blood flow/Cardiac Output
Even V/Q
Unchanged PaO2/PaCO2
5 changes w/ High Altitude
↓PAO2 (<760?)
respiratory alkalosis
EPO  Hb
↑2,3 BPG
Pulm vasoconstriction ( ↑PA pressure  LVH)
