Abstract
Provided are a method for controlling an oxygen provider and a portable device. The method includes: acquiring measurement data at a patient side; determining an oxygen demand volume and an output pattern of an oxygen provider based on the acquired measurement data and a desired oxygen fraction ratio; and controlling the oxygen provider with the oxygen demand volume and the output pattern. With the method or device for controlling an oxygen provider, oxygen with an amount that actually needed by a patient is provided to produce the blended gas to be delivered to the patient, and the blended gas delivered to the patient are regulated according to the output pattern to guarantee the blended gas is delivered in synchronization with the inspiration of the patient, so that a therapeutic effect is achieved with a lower oxygen consumption amount.
