Final answer:
CPR is an emergency technique used to manually compress the heart and maintain blood flow. Proper training is essential to perform CPR correctly and avoid injuries to the patient. CPR courses provide hands-on practice on a mannequin to ensure participants are certified and recertified.
Step-by-step explanation:
CPR stands for cardiopulmonary resuscitation, an emergency technique used to manually compress the heart and maintain blood flow when it has stopped. To perform CPR, you should first remove any barriers and then administer 30 chest compressions. By applying pressure to the sternum between the lines at T4 and T9, the blood within the heart will be squeezed out and circulated to vital organs.
It's important to note that proper training is essential for performing CPR correctly and avoiding injuries to the patient. CPR courses are widely available and provide hands-on practice of the compression technique on a mannequin, ensuring that participants are certified and recertified in its application.
