The formula to calculate Peak Flow is:
\[ PF = (H \times 5.3) - 433 \]
Where:
Peak Flow (PF) is a measure of how quickly a person can exhale air from their lungs. It is commonly used in respiratory health to monitor conditions such as asthma. The Peak Flow value is calculated based on the person's height, as taller individuals generally have larger lung capacities.
Let's assume the following value:
Using the formula:
\[ PF = (170 \times 5.3) - 433 = 470 \text{ L/min} \]
The Peak Flow (PF) is 470 L/min.
