There are people with long standing health issues that include CHF, diabetes, hypertension and renal failure. Physicians currently use heart/lung machines on a patient during surgery. However, instances of being connected to equipment that are complex may put more strain on a heart that is already compromised due to heart disease or other illnesses that over time cause heart failure, this also includes being on a lot of medications. How can a more portable machine be used on a patient during surgery?
If a patient has a very weak heart, brain damage and death can occur if there is not enough oxygen
in the blood to travel to the brain. When using a ventricular assist device on a patient, when they are undergoing surgery on another part of the body other than the heart; may be the way to go because it does performs the hearts function, without the cumbersome effects of equipment that may induce pressure on a weakened heart. These types of machines should also be equipped with a saline ice or saline solution of dry ice to be pumped through to the heart in a stream of doses. Why? Because once this saline solution of dry ice is sent through to the heart it will cool the heart, during surgery or even when using the ventricular assist device without the need for surgery. Once the heart is cooled it needs less oxygen to function. The less oxygen a heart needs reduces the chance that the heart will be deprived or starved of oxygen. The saline ice or saline solution of dry ice can be very useful when used with the ventricular assist device because it can be used to preserve the heart function in an emergency situation if there is an equipment malfunction or if the battery is low and needs to be charged. This will prevent the heart and surrounding tissue and ultimately the brain from being damaged due to the need for oxygen.
Now there's a reason to be as cold as ice!
