Final answer:
If a child collapses with no breathing and no pulse, start CPR immediately, ensuring proper technique and hand placement between lines at T4 and T9, and performing at a rate of 100 compressions per minute.
Step-by-step explanation:
When you witness the collapse of a child and confirm they have no breathing and no pulse, the next step is to start CPR immediately. It is critical to act swiftly as irreversible brain damage and death of neurons occur within minutes of the loss of blood flow. High-quality chest compressions should be performed with proper hand positioning on the sternum between the lines at T4 and T9 and at a rate of 100 compressions per minute. Training in CPR technique is highly valuable and courses are often available through various organizations.
If you witness the collapse of a child and you are the only rescuer without a mobile phone, your next step should be to start CPR immediately.
CPR, or cardiopulmonary resuscitation, is a life-saving technique that can maintain the flow of blood until the heart resumes beating. By applying pressure to the sternum, the blood within the heart can be squeezed out and circulated throughout the body.
It is important to remember that CPR is time-sensitive, as irreversible damage and death of neurons can occur within minutes of a loss of blood flow. Therefore, it is crucial to begin CPR as soon as possible.
