|Treatment of ARF||Period of care and resolution of the disorder that caused respiratory failure and prompted mechanical ventilation|
|Suspicion||The point at which the clinician suspects the patient may be ready to begin the weaning process|
|Assessing readiness to wean||Daily testing of physiological measures of readiness for weaning (MIP, fR/VT) to determine probability of weaning success|
|Spontaneous breathing trial||Assessment of the patient's ability to breathe spontaneously|
|Extubation||Removal of the endotracheal tube|
|Reintubation||Replacement of the endotracheal tube for patients who are unable to sustain spontaneous ventilation|
ARF: acute respiratory failure, MIP: maximal inspiratory pressure, fR/VT: respiratory frequency to tidal volume ratio (rapid shallow breathing index).
