Three different tidal volumes (Vt) were tested (500, 750, and 1000 mL) with HC and LC lung models, and the fresh gas flow rate was 1 L/min. To calculate the marginal propensity to consume, the change in consumption is divided by the change in income. If the value of (By) is higher, the total consumption value will increase. First, do the walking test (a detailed description of how to do this properly is in the section above). (760 47) x 0.21 = 149.7. Her smoking history would be recorded as:45 pack years, 53.
