When I found the Human Anatomy Course by Dr James Ross, I realized that I had found a very comprehensive, but simple and easy to understand anatomy and physiology course. What impressed me further was all the bonus material that came with the course. The bonus includes a comprehensive module on nursing and paramedic care. In this post I want to highlight some of the facts that I have learned from the Cardiopulmonary Resuscitation course (CPR) for health care professionals included in this module. Please be aware that this is not a medical site and that the aim of this website is only to give insight into the CPR course as presented by Dr James Ross in his Human Anatomy Course.
The term Cardiopulmonary Resuscitation can be broken down into the words cardio meaning heart, pulmonary which refers to the lung and resuscitation which means bringing a person who appear to be dead (clinical death) back to consciousness. Therefore during CPR, heart function (blood circulation) and lung function (breathing) are restored. Cardiopulmonary Resuscitation is an emergency procedure and the objective of CPR is to maintain circulation and breathing until emergency medical help arrives.
Cardiac arrest (sudden death) is the sudden and unexpected cessation of pulse and blood circulation. The main cause is myocardial infarction or heart attack. Other causes include drowning, electrical shock, poisoning, drug reaction, suffocation, smoke inhalation, choking, anaphylactic shock and trauma.
Cardiac arrest can lead to clinical death which occurs as soon as a person’s heart stops beating or they stop breathing resulting in a loss of consciousness. On the other hand biological death is non-reversible and normally occurs within 6 to 10 minutes after clinical death if efforts to restore respiration and heartbeat are not performed. CPR is used to reverse clinical death and prevent biological death usually outside of a hospital environment.
CPR really consists of two main activities namely performing rescue breathing and administering external chest compressions. These two activities are aimed at getting oxygenated blood to body cells before they die. Before rescue breathing can be performed the rescuer has to make sure that the airways are open and if required clear an upper airway obstruction.
As per Dr James Ross’s, Human Anatomy Course the following is a summary of the CPR procedures:
- Check for responsiveness and spinal injury.
- Call for help and place the casualty on their back on a hard surface.
- Open the airways.
- Check breathing (look, listen, feel).
- Give two breaths.
- Check carotid pulse.
- Locate compression site.
- Administer CPR cycles.
- Check for spontaneous breathing after every 4 CPR cycles, about every minute.
- Continue CPR, checking for spontaneous breathing and heartbeat every minute.
- Evacuate the casualty.
It is important to learn CPR in a practical environment, but I found it very useful to brush up on my skills by working through this course and being reminded what is important when you find yourself in an emergency situation and have to act fast.
So, if you are looking for a human anatomy & physiology course, a comprehensive nursing course or paramedic course, check out Dr James Ross’s Human Anatomy Course online. It will teach you everything you need to know about anatomy and physiology in a simple and easy way and as a bonus it will give you a detailed guide with pictures and diagrams to learn or practice you CPR skills.
