what does a heart-lung machine do for caval-pulmonary artey anastomosis
People can live for minutes after their heart stops. The risks of severe and permanent brain and tissue damage increase the longer the heart remains stopped, but it can be successfully retsarted if the right treatment is used.
A defibrillator is a machine commonly used by health care professionals (e.g. EMT, nurses, Doctors, etc.). This machine is used in order to shock a humans heart back into a regular rhythm. The way your heart works is that you have small nodes of cells called pacemakers sending electrical pulses to your cardiac muscles that tell your heart when to pump blood. When these electrical pulses stop, your heart stops beating. When this happens, a defibrillator is used to shock the heart muscles and the pacemakers back into action. If the heart stops beating (asystole), chemicals may be administered to "restart" the heart. A defibrillator is used when the heart is beating, but irregular (arrhythmia). The shock causes all of the cardiac muscle cells to contract at the same time. This usually corrects the irregular heart beat. The way this is achieved is by rubbing the two panels of the defibrillator together to create an adequate electrical current, then the doctor or fireman will shout "clear" so that no humans other than the patient are shocked (electrical current through the body) or electrocuted (killed by shocking).
You can image the heart using: echocardiogram, Magnetic Resonance Image, Computer Tomography Scanning
it is used to change directions
When a machine stops, its kinetic energy is converted into other forms of energy such as thermal energy or sound energy due to friction and other factors. Essentially, the kinetic energy is dissipated and transformed into different forms as the machine comes to a halt.
Electric shocks can be given in certain types of heart-attacks. When the heart has trouble beating it gets what is called fibrillation. The electric device that stops that is called a defibrillator because it shocks the heart into beating normally.
To put it simply, an Automated External Defibrillator(AED) is a machine used by rescuers that sends an electrical current through the heart to "reset" the heart beat.
The heart is not considered a simple machine; it is an organ that functions as a pump to circulate blood throughout the body. Simple machines are typically mechanical devices that can be used to make work easier, like levers or pulleys.

Potassium chloride is commonly used in lethal injections as it stops the heart by disrupting the balance of potassium ions in the body.
