What is normal negative inspiratory pressure?
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 a good NIF score?
An NIF ≤–25 cm H2O predicts spontaneous breathing trial success, and an NIF ≤–26 cm H2O predicts suc- cessful extubation.
What is a NIF ventilator?
Negative Inspiratory Force is a measurement of respiratory muscle strength and ventilator reserve. NIF is one of several clinical indicators that are often used to assess a patient’s ability to be successfully “weaned” and liberated from mechanical ventilation.
What is the meaning of NIF?
|NIF||Negative Inspiratory Force|

What is NIF program?
The Neighborhood Initiatives Fund (NIF) Program is intended to assist nonprofits (including government agencies) and community-based organizations with neighborhood-scale projects in commercial corridors.
What is NIF and vital capacity?
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.
How do you do a NIF test on vent?
To measure NIF: • Select Menu > Lung Mechanics >NIF. Set NIF Time. Use the Trim Knob to select a NIF time up to 30 seconds. Instruct the patient to fully exhale.
What is NIF ventilator weaning?
It has been established that a NIF ≥-20 or -25cm H2O is adequate to initiate ventilatory weaning; With a NIF>-30cm H2O, there is a 93% chance of successful weaning [20,21], and on the contrary, with a NIF of >-15 or >-10cm H2O, patients are unable to breathe on their own (twenty-one).
Is a NIF of 30 good?
An NIF value less than –30 cm H2O is the criterion for starting the mechanical ventilator weaning process [2,10].
