Brief summary
To quickly assess the patient's cardiac function and structure through ultrasound
Detailed description
Monitor the peripheral arterial pulse and flow velocity, monitor the patient's lung and diaphragm muscle movement, monitor the patient's optic nerve sheath and cerebral blood flow, observe the morphology and blood flow of the liver and kidney and other parenchymal organs, Comprehensive evaluation of patient resuscitation quality. For patients with cardiac arrest undergoing Cardio Pulmonary Resuscitation (CPR), the above monitoring was completed by ultrasound, and compared with the parameters obtained by end-expiratory carbon dioxide (ETCO2) and compression feedback device, to evaluate the feasibility of ultrasound to evaluate the quality of CPR. After the reliability evaluation was completed, parameters were further used to guide CPR quality improvement through ultrasound, end-expiratory carbon dioxide (ETCO2), and compression feedback device.
Interventions
DIAGNOSTIC_TESTUltrasound
Every time checking pulse, evaluate the carotid artery compressibility and blood flow of peripheral arteries by ultrasound，compared with EtCO2.
