Negative inspiratory force definition
WebNegative 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 H 2 O, 100% of the weaning attempts are expected to fail. b. With an NIF >20 cm H 2 O, 60% of the weaning attempts are expected to succeed. c. WebBedside spirometry (negative inspiratory force and forced vital capacity) is an accurate bedside measure of a patient's readiness to wean. Fluoroscopic examination of the diaphragm and phrenic nerve conduction studies were not helpful in determining weaning potential in ventilator-dependent patients with cervical spine injury.
