METHOD AND SYSTEM FOR NON-INVASIVE VENTILATORY SUPPORT

摘要

A method and apparatus for supplying regulated air to a patient requiring a respirator. An airflow amplifier is provided with increme digital control of an air gap providing compressed primary air to the amplifier. The compressed air induces and entrains ambient air, providing for a amplified flow of non-turbulent air to the patient. The combined flows are subjected to rapid and repetitive measurements of pressure and flow conditions, which measurements serve as feedback data for maintaining operation of the system under precise controls In various modes, the method and system of the invention provide for assistance of the patient's spontaneous breathing, which can be overridden by timing means, if the patient fails to breaths naturally for an excessive period. Passive air amplification provides for extremely quiet operation, allowing assisted patients to sleep effectively. The system is not only highly effective, but exceptionally economical to install and operate.
