Question | Answer |
Physiologic Dead Space | Vd = Vt X (PAco2 - PEco2)/PAco2 |
minute ventilation | Tv X bpm |
Alveolar ventilation | (Tv-Deadspace) x bpm |
Dead Space | Vt X (PAco2-PEco2 / PAco2) |
Normal value of FEV1/FVC | 0.8 |
Total Lung Capacity | Sum of all 4 lung volumes |
compliance | volume/pressure |
Airflow | Q=P/R |
Poiseuille's law | R= 8nl/(pi)r4 |
Asthma FEV | decreased |
COPD FEV1 | decreased |
Fibrosis FEV | slightly decreased |
Asma FVC | slightly decreased |
COPD FVC | slightlly decreased |
Fibrosis FVC | Greatly decreased |
FEV1/FVC asthma | decreased |
COPD FEV/FVC | drecreased |
Fibrosis FEV/FVC | normal or increased |
FRC asthma | increased |
FRC COPD | increased |
FRC Fibrosis | decreased |
Partial Pressure | Total Pressure X Fractional gas concentration |
Fractional Gas concentration of O2 | 0.21 |
partial pressure of h2o | 47 mmHg |
Partial pressure of Po2 in trachea | 150 |
PO2 of dry air | 160 |
Po2 of alvolar air | 100 |
PO2 of arterial blood | 100 |
PO2 of venous blood | 40 |
Pco2 of arterial blood | 40 |
Pco2 of venous blood | 46 |
Pco2 of dry inspired air | 0 |
O2 percentage in air | 21 |
CO2 percentage in air | 0.03 |
Percentage of N2 | 79% |
Pulmonary Vascular Resistance | (Pa – Pv)/flow rate |
The laboratory provides the following report on arterial blood from a patient: PCO2 32 mmHg, pH 7.25, HCO3- concentration 25 mmol/liter. | pH = 6.1 + log [HCO3-]/[CO2] = 6.1 + log (25/0.03 x 32) |
alveolar gas equation | PAO2 = PIO2 – (PACO2/R) |
