What is the normal negative inspiratory force?
Regarding this, what is a good NIF for extubation?
NIF of at least -30 cm H2O has been found predictive of extubation success in adults[76,77] and also in children as part of the CROP index[18,31] or as a stand-alone test under rigorous conditions with CO2 stimulation.
Also, what is NIF and vital capacity? A negative inspiratory force (NIF) of 30 cm H2O or less or a forced vital capacity (FVC) of 20ml/Kg are indicative of a myathenic crisis and airway compromise. Evidence of hypoxemia, poor respiratory effort, or CO2 retention is an indication for intubation and mechanical ventilation.
Also Know, what is a normal inspiratory pressure?
Normal adults can develop maximal inspiratory and expiratory pressures against an occluded airway in excess of -100 and 200 cm H2O, respectively. Occlusion pressures can be measured during crying in infants as young as one month of age.
What should I look for after extubation?
Post-Extubation Management If needed consider CPAP/BPAP for selected high-risk patients to avoid re-intubation. Ensure adequate secretion management, encourage coughing and deep breathing, maintain airway hydration and patent central airway. Use adequate bronchodilators as needed.
