Maximal inspiratory pressure (MIP) MIP, also known as negative inspiratory force (NIF) , is the maximum pressure that can be generated against an occluded airway beginning at functional residual capacity (FRC). It is a marker of respiratory muscle function and strength.aximum inspiratory pressure is an important and noninvasive index of diaphragm strength and an independent tool for diagnosing many illnesses. Typical maximum inspiratory pressures in adult males can be estimated from the equation, M IP = 142 - (1.03 x Age) cmH 2 O, where age is in years.
