Normal reference ranges expressed as the lower limit of normal

Male MIP reference = 120 – (0.41 × age)	Male MIP LLN = 62 – (0.15 × age)
Male MEP reference = 174 – (0.83 × age)	Male MEP LLN = 117 – (0.83 × age)
Female MIP reference = 108 – (0.61 × age)	Female MIP LLN = 62 – (0.50 × age)
Female MEP reference = 131 – (0.86 × age)	Female MEP LLN = 95 – (0.57 × age)

MIP: maximal inspiratory pressure; LLN: lower limit of normal; MEP: maximal expiratory pressure.
