Foundational Equations
| Ohm's Law | $\Delta P = FR = P_{aw} - P_{alv} = P_{pl} - PEEP_{total}$ |
|---|---|
| Equation of Motion | $P_{aw} = FR + \frac{V_{t}}{C} + PEEP_{total}$ |
| Compliance | $C = \frac{\Delta V}{\Delta P}$ |
| Natural Decay Equation | $V_i(t)= \frac{V_o}{e^{\frac{t}{RC}}} = \frac{V_o}{e^{\frac{t}{\tau}}}$ |
| Calculating $\Tau$, General Case | $ \tau = \frac{V_t}{F} \Bigg(\frac{PIP - P_{plt}}{P_{plt} - PEEP_{total}}\Bigg) $ |
| Calculating $\Tau$, Special Case* | $ \tau = -\frac{V_t}{F} $ |
*Assumes (1) no autoPEEP and (2) patient is passive.
