Final answer:
The weaning parameter for Negative Inspiratory Force (NIF) is a measure of the strength of a person's inspiratory muscles. It is used to assess the ability of an individual to generate negative pressure during inspiration.
Step-by-step explanation:
The weaning parameter for Negative Inspiratory Force (NIF) is a measure of the strength of a person's inspiratory muscles. It is used to assess the ability of an individual to generate negative pressure during inspiration. NIF is commonly measured by having the person inhale forcefully against a blocked airway, and the maximum negative pressure achieved is recorded.
