Cardiopulmonary resuscitation key points

Cardiopulmonary resuscitation (CPR), also known as cardiopulmonary resuscitation (CPR), is a mechanical device used to treat cardiac arrest. With the development and progress of science and technology, it is also constantly improved and perfected according to clinical needs. The instrument is suitable for patients with chest traumatic cardiac respiratory arrest, respiratory muscle weakness and respiratory depression under general anesthesia, especially for those with chest deformity, chest trauma, thoracic rib fracture, blood pneumothorax and other contrainditions for chest compressions. It is an ideal choice for cardiopulmonary resuscitation in contraindicated patients with chest compressions. It is an ideal measure after chest and rib fracture during CARDIopulmonary resuscitation. It is an ideal choice for emergency artificial respiration during cardiopulmonary resuscitation.

There is no way to predict when a sudden cardiac arrest will occur, but there are warning signs before the onset of a sudden cardiac arrest. These are called "three pains," chest pain, abdominal pain, and headache. On the premise of ensuring the safety of the surrounding environment, the key points to identify whether the fallen patient has cardiac arrest in advance are mainly "three stops", namely, stop of consciousness, stop of breathing and stop of heartbeat. Once cardiac arrest occurs, the typical manifestation is a sudden loss of consciousness. The patient may suddenly fall without any reason and should not shout. Then there are no signs of circulation (heartbeat), such as speech, vocalization, physical activity, and loss of pulse. The patient experiences breathing abnormalities, cessation of breathing, or near-death sighing breathing, which is hard sobbing breathing at long intervals. Usually, if the breathing stops (the chest does not rise or fall) or if it is abnormal for more than 5 seconds, we will consider cardiac arrest and should immediately start cardiopulmonary resuscitation (CPR).

Device press frequency: 100 times/min, 110 times/min, 120 times/min three gear adjustable. The pressing depth is 0-7cm, the actual pressing depth is > 5cm, the pressing depth can reach 7cm, visible, continuous jing can be adjusted. The ventilators range from 0 to 1500ml, and the ventilators can reach 1500ml. Ventilation time is adjustable for 1s, 1.5s and 2S. Fully automatic synchronously continuous pressing and breathing 30:2 mode, 15:2 mode; Press CCV mode continuously.

The equipment adopts electric pneumatic operating principle, piston type chest contact press, chest no load classic vertical press rather than binding extrusion structure, in line with the first aid guidelines. The double rigid fixed column of the compressors is marked to indicate the patient's actual chest thickness. The compressors are fixed with a double rigid column slide track, which can slide back and forth and move up and down to lock. The compressions can be quickly determined without moving the patient. The equal-height backplane is designed to facilitate the patient's head to recline and effectively open the airway. It has the function of ventilating voice prompt, and gives the buzzer prompt when pressing the number of times to count to 5. It has the function of automatic pressure relief when the input gas pressure is too high. When the input oxygen pressure is ≥ 0.7mpa, the pressure relief valve opens. The operating panel of equipment parameters is located below the patient to avoid the contamination of vomitus affecting the clinical rescue efficiency. The control panel interface of cardiopulmonary resuscitation apparatus adopts mechanical or touch-tone control panel with non-LIQUID crystal display, which can avoid blind sight under strong outdoor light and affect parameter setting.
