WHAT IS A CABG?

What is a CABG?
CABG stands for Coronary Artery Bypass Graft.
It is not a virtual cabbage. CABG (pronounced cabbage)
is a surgical procedure done to improve the heart's
circulation in a patient with CAD (coronary artery
disease)

How is a CABG done?
A blood vessel (an artery or vein) is taken from
another part of the body and used to reroute blood
 (bypass the blocked vessel) to the heart. An artery
or vein from the leg or chest is typically used.

What are some common symptoms of CAD?
Patients who have severe CAD will experience
symptoms such as:
- Chest pain
- Shortness of breath
- Dizziness
- Hypotension

Why do these symptoms occur?
This is due to a lack of blood flow in the blood
vessels caused by a clot or plaque. The decrease
in blood supply results in insufficient oxygen to
the heart muscle.


 
Scenario: Tim was brought to the ER in respiratory distress.
He has a previous history of MI and CHF. He also had a
CABG done 1 year ago. Some of the tests that have been
 ordered for him include an ABG, EKG, and chest x-ray.

The Electrical Conduction System of the heart

The SA (sinoatrial) node is the pacemaker of the 
heart and is part of the electrical conduction system.
It is located in the upper part of the right atrium.
When the SA node fires, the right and left atria
contract simultaneously and blood is forced into
the right and left ventricles.

 Scenario: Jim was admitted to the medical floor, with
complaints of abdominal pain. The nurse arrives at his
bedside and finds him unresponsive. She presses the code
button, to alert the code team. She then begins CPR.

What does CPR mean? 

CPR means Cardiopulmonary resuscitation. When the
heart stops beating and there is no circulation of blood
throughout the body, CPR is initiated.

Lack of blood supply to the brain and vital organs,
may permanent damage if left untreated. Above,
medical personnel are being given instructions
about the correct techniques to use when doing CPR.
