What is a normal NIF?

The NIF test is measuring the strength of the diaphragm muscle itself. The average vital capacity for adults not affected by ALS is between 80 – 120%, and a normal NIF is a reading greater than -60 on the pressure meter.

What does a negative NIF mean?

Negative inspiratory force (NIF) is a relatively easy bedside test to measure respiratory muscle function and can easily be performed every half hour to hour in difficult cases. Normal is usually greater than 60 cm water. If the NIF is dropping or nears 20 cm water, respiratory support needs to be available.

What is NIF on ventilator?
