    摘要: Provided is a congestive heart failure therapy device that applies a positive pressure within an optimal range depending on the condition of a congestive heart failure (CHF) patient. Provided is a positive pressure therapy device for congestive heart failure patients, comprising: a pressure raising unit configured to raise the pressure of air, or a gas mixture of air and other gases, to a positive pressure; an introducing unit configured to introduce the air or the gas mixture set to a positive pressure into the airways of the patient; and a blood oxygen level measurement unit configured to measure the blood oxygen level of the patient, a blood flow rate measuring unit configured to measure a blood flow rate of the patient, or a cardiac output measuring unit configured to measure a cardiac output of the patient. A control unit monitors the blood oxygen level, the blood flow rate or the cardiac output and, if the value thereof is less than or equal to a fixed value, the control unit determines that the positive pressure being applied is not suitable and controls the pressure raising unit to change the positive pressure value. By controlling the pressure raising unit while monitoring the blood oxygen level, the blood flow rate or the cardiac output, the positive pressure can be applied within an optimal range based on the preload state of the congestive heart failure patient.
