Nif respiratory parameters
WebJul 1, 1996 · The spontaneous respiratory rate:tidal volume ratio (RVRi), negative inspiratory force (NIF), and spontaneous minute volume (V,) at the onset of weaning, and the RVR at 30 to 60 minutes of weaning (RVRBO) were measured. Weaning decisions were made by patients’ primary physicians independent of this study. WebStandard weaning criteria (SWC) evaluate respiratory muscle strength and endurance by using negative inspiratory force (NIF) and positive expiratory pressure (PEP). Another …
