The principle of artificial respiration is to give oxygen artificially to replace the patient’s voluntary breathing when the patient’s heartbeat is apneic and life-threatening, so as to prevent irreversible and serious damage to vital organs due to lack of oxygen.
The principle of artificial respiration is to use external force to passively deliver fresh air to the lungs of apneic patients in order to temporarily maintain respiration and blood circulation, to ensure the supply of oxygen to vital organs, and to replace the patient’s voluntary respiration with artificial respiration.
If the patient’s heartbeat and respiration are suspended due to drowning, shock, cerebral hemorrhage and other various reasons, at this time the patient has lost the ability to breathe on his own, and if he is not resuscitated in time, it will result in irreversible damage to the patient’s brain and other vital organs and tissues of the human body in 4 to 6 minutes, causing serious consequences.
After the patient’s apnea, we should immediately remove the mouth and nose foreign body, make the airway open, at the same time as soon as possible artificial respiration. Oxygen is also available in the human body’s exhaled gas, which can be delivered to the patient to ensure the supply of oxygen to vital organs.
