What is a NIF on the lung?
Negative Inspiratory Force (NIF): is the maximum pressure that is generated against an occluded airway after a. maximum inspiration. • Helps assess inspiratory muscle function or diaphragmatic force.
What is a normal NIF value?
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 NIF measure?
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 NIF and FVC?
4. Forced vital capacity (FVC) and negative inspiratory force (NIF) are the gold standards for monitoring respiratory muscle strength.
What is a good NIF for extubation?
An NIF ≤–25 cm H2O predicts spontaneous breathing trial success, and an NIF ≤–26 cm H2O predicts suc- cessful extubation. lated using the formula for the cross-sectional study , and, based on a study by Thille et al. , the proportion of extuba- tion success was 80%.
How is NIF calculated?
Negative inspiratory force (NIF) is measured by asking the patient to inhale as forcefully as possible and measuring the maximum negative pressure generated. a. With an NIF<20 cm H2O, 100% of the weaning attempts are expected to fail.
Is a NIF of 30 good?
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).

What NIF to Extubate?
An NIF ≤–25 cm H2O predicts spontaneous breathing trial success, and an NIF ≤–26 cm H2O predicts suc- cessful extubation.

What is NIF in ICU?
NIF, also known as negative inspiratory pressure or maximal inspiratory pressure, is a commonly used clinical parameter to assess extubation readiness by assessing diaphragmatic strength during the inspiratory phase.
