dalton's law
✓ Pair = Po2 + Pn2 + Pco2 + Par
henry's law
✓ C = alphaP
✓ the concentration/amount of a dissolved gas is a function of the gas's Pp and solubility
coefficient
partial pressure calculation
✓ Pgas = Fgas * Patm
inspired partial pressure
✓ Pi,o2 = Fo2 * (Patm - Ph2o)
✓ air conditioning during inhalation: adds warmth and moisture to the gas --> water gets
evaporated in the mucosa, generating a water pressure which decreases the atmospheric
pressure
✓ at 37C, Ph2o= 47 mmHg
alveolar partial pressure

✓ PA = Pi,o2 - Po2 = 150 mmHg - 50 mmHg = 100 mmHg
✓ Pi,o2 = Fo2 * (Patm-Ph2o) = .21(760-47) = 150 mmHg
✓ Po2 = Pa,co2/RQ = 40 mmHg/0.8 = 50 mmHg
✓
✓ how much oxygen is diffusing out of the alveoli
fick's equation
✓ V = ((PA-Pb)*A*D/)T OR V/A = ((PA-Pb)*D/)T
✓ V = flow rate
✓ PA-Pb = pressure gradient
✓ A = surface area
✓ D = diffusion coefficient
✓ T = thickness/distance
✓ V/A = net rate of particles moving through A; flux
✓ (PA-Pb)/T = change in P over a distance
✓ D*A/T = diffusion capacity, D(L)
fibrosis and fick's equation
✓ smoke cannot be destroyed by macrophages --> production of collagen -->
collagen/scar tissue on the alveoli --> increase in T --> decrease in gas exchange
emphysema and fick's equation
