Chest compressions are the most important part of cardiopulmonary resuscitation. It involves pressing the heart below the sternum and pushing oxygen and nutrients to the core organs of the body. When performing chest compressions, make sure to put your hands in the right position to ensure that the compression can achieve the maximum effect.
Artificial respiration is another important part, which includes injecting air into the patient's lungs through mouth-to-mouth or mouth-to-mouth manner. This helps to maintain the patient's respiratory function in the case of cardiac arrest. When performing artificial respiration, make sure that the head is in the correct position to avoid any situation that hinders breathing.
Candidates need to prove that they have mastered these skills when taking the CPR training exam. Exams usually include simulations of chest compressions and artificial respiration to ensure that candidates can correctly perform these skills in real emergencies. In addition, the exam also includes relevant theoretical knowledge and emergency procedures to ensure that candidates know how to take correct actions in an emergency.
In short, cardiopulmonary resuscitation is a very important skill and can save lives. Everyone should learn these skills in order to take action in an emergency. The CPR training exam is an important step to ensure that everyone has mastered these skills.
