MIP
Also written as: MIP — Maximum Inspiratory Pressure
Maximum inspiratory pressure measurement that assesses respiratory muscle strength and readiness for extubation.
Full Definition
Maximum inspiratory pressure (MIP), also known as negative inspiratory force (NIF), is a measurement of the maximum pressure a patient can generate during inspiration against an occluded airway. This test evaluates inspiratory muscle strength and is commonly used to assess readiness for ventilator weaning and extubation. Normal MIP values are typically more negative than -60 cmH2O in healthy adults, while values greater than -20 cmH2O may indicate significant respiratory muscle weakness. Respiratory therapists perform MIP measurements as part of comprehensive weaning assessments, along with other parameters such as vital capacity and rapid shallow breathing index.
Usage
Usage note: Values are typically negative; more negative values indicate stronger inspiratory muscles.
In Context
- "The patient's MIP of -35 cmH2O suggests adequate inspiratory muscle strength for extubation consideration." — Weaning assessment report
- "Measure MIP daily during spontaneous breathing trials to monitor respiratory muscle recovery." — Ventilator weaning protocol
