How is Vital Capacity Measured |
Using a Spirometer |
|
|
Exhaled Tidal Volume Equation |
VT = VE/RR |
|
|
Minute Ventilation Equation |
VE = VT × RR |
|
|
Alveolar Ventilation Equation |
VA = (VT - VD) × RR |
|
|
Dead Space Value |
1 mL/lb |
|
|

CMV |
|
|
Improve Alveolar Ventilation |
Increased VT |
|
|
Kilos to Pounds |
Pounds = Kilos × 2.2 |
|
|
Mechanical Dead Space Meaning and Approximation |
Circuit Tubing Adds CO2 10 mL per inch of Tubing |
|
|
Anatomic Dead Space |
Amount of Inspired Tidal Volume That Does not Enter the Alveoli. Used to approximate alveolar ventilation. |
|
|
Anatomic Dead Space Approximation |
1 mL per lb of IBW |
|
|
Alveolar Deadspace |
Alveolar Ventilation with no Perfusion |
|
|
Physiologic Deadspace |
Sum of anatomic and alveolar Deadspace. Estimated by VD/VT ratio |
|
|
Dynamic Compliance |
Flow in Airways |
|
|
Dynamic Compliance Equation |
VT/(PIP - PEEP) |
|
|
Normal Dynamic Compliance |
30 - 40 mL/cmH2O |
|
|
Static Compliance |
Pressure in that is always in the lungs |
|
|
Static Compliance Equation |
VT/(Pplat - PEEP) |
|
|
Normal Static Compliance |
60 - 100 mL/cm H2O |
|
|
Decreased Compliance leads to |
Stiffer Lungs Higher Ventilation Pressures |
