초록 ▼

The system and method for flow triggering pressure supported ventilation include a source of a predetermined, preinspiratory, constant flow of breathing gas to a patient, one or more flow sensors for measuring the rate of gas flow in a flow path communicating with the patient, means for determining when inhalation from the flow path has occurred, and means for generating pressure support in the delivered gas flow in response to inhalation by the patient, means to terminate pressure support when inspiratory phase concludes, and means to reestablish the predetermined, preinspiratory, continuous flow of breathing prior to the patient\s next inspiratory effort. A plurality of individual gas sources preferably provide a controlled mixture of breathing gas. In combination with pressure support to the patient during the inspiration effort, the flow triggering strategy of the invention offers significant improvements in providing breath support to patients having weakened respiratory capabilities.

대표청구항 ▼

A method of triggering pressure supported ventilation to a patient supplied with breathing gas from a ventilation system having a source of breathing gas, a patient breathing attachment, an exhalation valve, and a functionally open ventilation flow path in fluid communication with said source of breathing gas, said patient breathing attachment, and said exhalation valve, said ventilation flow path including flow sensor means for measuring flow rate of said breathing gas from said source of breathing gas to said patient and for measuring flow rate of said breathing gas from said patient breathing attachment to said exhalation valve, the steps of the method comprising: setting a predetermined threshold value; setting a preinspiratory, predetermined continuous rate of flow; delivering breathing gas from said source to said patient breathing attachment at said preinspiratory, predetermined continuous rate of flow; measuring said flow rate of breathing gas from said source of breathing gas to said patient breathing attachment to determine a gas supply flow rate; measuring said flow rate of breathing gas from said patient breathing attachment to said exhalation valve to determine an exiting gas flow rate; determining patient inspiratory effort in said flow path by a) comparing said gas supply flow rate with said exiting gas flow rate and b) determining a flow rate difference due to inhalation, thereby indicating the patient\s inspiratory effort; generating pressure support in said breathing gas delivered from said source to said patient when said flow rate difference due to inhalation exceeds said predetermined threshold value; determining the beginning of the patient\s exhalation cycle; reducing the gas supply flow rate for a predetermined period of time at the beginning of said exhalation cycle; and restoring delivery of said breathing gas from said source to said patient breathing attachment at said preinspiratory, predetermined continuous rate of flow before a next patient inspiratory effort.
