The device may be used in weaning trials of spontaneous breathing, or in conjunction with ventilator assistive modes of all types. Used in conjunction with a plurality of ventilators the device may signal the ventilator to assist if the patient's attempts to breathe fall below predetermined safe levels of ventilation. The device may also be used to prompt patients in acute respiratory failure in correct breathing patterns for proper use of non-invasive ventilator assistance in order to prevent the need for invasive intubation.

[ What is claimed is:] [1.]1. A method for monitoring a respiratory patient to evaluate and train the patient for respiratory ventilator weaning, comprising:measuring the patient's respiration air volume during a series of spontaneous breathing cycles for establishing patient respiration parameters;establishing a visual patient inspiration and expiration breathing pattern comprising determined tidal volume, respiratory rate, inspiration to expiration time ratio, end inspiration and end expiration breath hold times, and inspiration and expiration waveforms;evaluating patient respiration performance data during a further series of spontaneous breathing cycles and comparing said respiration performance to the established visual patient inspiration and expiration breathing patterns;sensing substantial deviation from the established respiratory pattern by error limits;providing an actuation signal in response to sensed deviation; andproviding ventilator operation for assisted respiration in response to the actuation signal.
