Abstract

A method for assessing volume responsiveness and medical equipment, the medical equipment comprising a respiratory assistance device (110) for providing breathing support to a patient, a first sensor (120) and a processor (140) for collecting physiological parameters of the patient , when volume responsiveness assessment is required, the processor controls the ventilation parameter to switch to the second ventilation parameter that can increase the variability of the patient’s intrathoracic pressure, and then at least uses the parameter variability measured under the second ventilation parameter that can reflect the patient’s heartbeat Assess the patient for fluid responsiveness. Because the second ventilation parameter can increase the variability of the patient's intrathoracic pressure, so that the variability of the parameters that can reflect the patient's heartbeat used to assess volume responsiveness increases, so it is possible to more accurately assess the patient's ability to respond to increased volume loading. No volume responsiveness.

Description

technical field [0001] The invention relates to a medical device, in particular to a volume responsiveness evaluation method. Background technique [0002] In the life monitoring of patients, hemodynamic parameters (such as blood specific viscosity, erythrocyte electrophoresis, erythrocyte sedimentation rate, fibrinolytic system function, etc.) may need to be monitored according to the patient's condition. When the hemodynamic parameters are unstable The first treatment option to consider is volume resuscitation, which stabilizes the patient's hemodynamic parameters by increasing the volume load to increase cardiac output. Volume load, also known as cardiac preload, refers to the load experienced by the heart muscle before it contracts, that is, the volume load or pressure on the ventricle during end-diastole. In clinical practice, volume responsiveness is usually used to measure whether an increase in volume load will cause a corresponding increase in cardiac output. [0...
