Boyle's law
|
PV = constant

|
|
Minute ventilation
|
Minute vent = f * tidal volume
|
|
|
Alveolar ventilation (1)
|
= (tidal volume - dead space volume) * f
|
|
|
Alveolar ventilation (2)
|
= 863 * (vent rate CO2 / PACO2)
note: PACO2 ~~ PaCO2 |
|
|
Restate Alveolar ventilation eq
|
= 863 * Vol CO2/min / PACO2
|
|
|
Alveolar gas equation
|
PA(O2) = PI(CO2) - (PA(CO2)/R)
Where PICO2 is generally around 147 Where R is generally arouns .8 But where R = Vent rate CO2/Vent rate O2 |
