VD/VT

In medicine, the ratio of physiologic dead space over tidal volume (V_D/V_T) is a routine measurement, expressing the ratio of dead-space ventilation (V_D) to tidal ventilation (V_T), as in physiologic research or the care of patients with respiratory disease.^[1]

Equation

\frac{V_{D}}{V_{T}} = \frac{P_{a} C O_{2} - P_{E} C O_{2}}{P_{a} C O_{2}}
