@nbrcboardexamssolution: Negative Inspiratory Force (NIF)—also referred to as Maximal Inspiratory Pressure (MIP)—is a foundational clinical metric used to evaluate overall respiratory muscle strength, particularly diaphragmatic function. It measures the maximum amount of negative pressure a patient can generate during a forceful inhalation against an occluded airway.
