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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The correlation between return of spontaneous circulation rate and peripheral blood flow through study completion, an average of 1 hour.
Time Frame: through study completion, an average of 1 hour.

For patients with cardiac arrest undergoing CPR, Peripheral arterial blood flow monitoring was completed by ultrasound, and compared with treturn of spontaneous circulation rate .

Bilateral carotid blood flow velocity:

  1. Peak systolic velocity, PSV, cm/s
  2. End diastolic velocity, EDV,cm/s
  3. Resistance index, RI
  4. Pulsatility index, PI Bilateral femoral artery blood flow velocity

1) Peak systolic velocity, PSV, cm/s 2) End diastolic velocity, EDV,cm/s 3) Resistance index, RI 4) Pulsatility index, P
through study completion, an average of 1 hour.
