Criteria for effective cardiopulmonary resuscitation

Cardiopulmonary resuscitation operation is correct, mainly depends on the usual strict training, master the correct method. To judge whether resuscitation is effective or not, cardiopulmonary resuscitation experts say the following aspects can be considered comprehensively:

1. When pupil resuscitation is effective, visible pupil shrinks by big, appear to light reflex. Such as pupil 7LA small become larger, fixed, corneal opacity. That means recovery is ineffective.

2. Bread (lips) resuscitation was effective, with visible complexion and/or lips changing from hair to ruddy; If the patient's bread turns gray, the test indicates that resuscitation is not effective.

3. When the carotid pulse presses the wind effectively, you can feel a pulse every time you press. If you stop pressing, the pulse will disappear, so you should continue to press the heart. If the pulse still beats after stopping pressing, the patient's heart has resumed. Square effect pressure, dE pressure can be measured at 60/40 cofferhg during pressing.

4. Conscious recovery is effective, visible patient has eye movement, eyelash reflex and reflex to light appear, even hands and feet began to twitch, muscle tension increased.

5. Spontaneous breathing shows that resuscitation is effective, but if breathing is still weak, mouth-to-mouth breathing or other respiratory support should be continued.

Cardiopulmonary resuscitation (CPR) simulator operation practice has well simulated the CPR rescue process:

1, open the airway will simulate people lie lie on your back, operation, operation of two fingers pinched nose with one hand, another hand into the neck or chin lift head thrown back and horizontal form 70 ~ 90 degree Angle, display the neck airway open the green light is lit up, according to instructions in order to form the airway open, facilitate artificial blowing, ventilation of the airway.

2, correct, wrong manual qigong can prompt; First of all, artificial mouth-to-mouth blowing (for example, in the on-site rescue, some patients can be closed and their upper and lower teeth are tightly bitten, so mouth-to-nose blowing cannot be carried out, mouth to nose blowing can be adopted, while the mouth of the simulated person is long open. If mouth-to-nose blowing is operated, the simulated person's mouth must be sealed by hand for mouth-to-nose blowing).

(1) The correct air blowing into the tidal volume reaches 500mL ~600ml, and the feedback of the correct air blowing information on the display is shown as the green indicator light. (2) The wrong mouth-to-mouth blowing, the way of blowing in is too fast or the amount of wet air is too large, exceeding 700 ml, causing the gas to enter the stomach, the red indicator light of the stomach on the monitor will be on, and there will be a "drip" alarm. (3) If the incoming tidal volume is less than 500ml, the feedback of insufficient air volume information will be shown by the yellow indicator light on the monitor, and there will be an alarm prompt of "drop". (4) If the incoming tidal volume is greater than 600ml to 700ml, the feedback of excessive air volume will be shown by the red indicator light on the display road, and there will be two sound alarms of "drip, drip".

3, right and wrong artificial compression function tip (a) location: first of all find out chest place two fingers on the sternum incised trace sternum is central (or chest chest xiphoid process up two fingers in the middle of nipple attachment level) for the correct pressure zone, arms crossed together, the simulated chest compressions arm is perpendicular to the area, for chest compressions. The pressing position is correct and the pressing area on the monitor is indicated by the green light. The pressing position is wrong and the pressing area on the monitor will turn into red indicating light with a "drop" alarm.

(2) pressing intensity :(1) the correct chest external pressing depth is 5cm, and the correct pressing intensity information on the monitor is reflected by the green indicator light. (2) Wrong pressing intensity. The pressing depth on the display is less than 4cm. The feedback of insufficient pressing is shown as yellow indicator light with an alarm indicating "drop". (3) The wrong pressing intensity and depth is more than 5cm. If the press is too heavy on the display, the feedback will be shown by the red indicator light, and there will be two sound alarms of "drip, drip".
