Final answer:
The amount of air inhaled can be calculated using the formula Volume Change = Compliance x Pressure Change. Substituting the given values, we find that the volume change is -0.5 L.
Step-by-step explanation:
To calculate the amount of air inhaled, we can use the formula:
Volume Change = Compliance × Pressure Change
Given that the compliance is 0.25 L/cm H2O and the pressure changes from -5 cm H2O to -7 cm H2O, we can substitute the values into the formula:
Volume Change = 0.25 L/cm H2O × (-7 cm H2O - -5 cm H2O)
Simplifying the equation, we get:
Volume Change = 0.25 L/cm H2O × -2 cm H2O
Therefore, the volume change, which represents the amount of air inhaled, is -0.5 L.
