CPR courses are designed to prepare individuals with basic skills necessary for life-saving treatment, and they are available at different locations.
Step-by-step explanation:
Proper training in CPR is essential to perform immediate life-saving treatment. CPR, or cardiopulmonary resuscitation, is a proven technique that can sustain life until professional medical help arrives. It involves manually compressing the chest to circulate blood and oxygen to vital organs. To ensure safety, CPR courses are offered by various organizations such as the American Red Cross and hospitals. These courses train individuals in the proper technique to avoid causing harm to the patient, such as broken ribs or damage to the liver.
