Heart Valve

• You have four heart valves in your body. A heart valve normally allows blood to flow in only one direction through the heart.

• The artificial heart valve is a device implanted in the heart of a patient with heart valvular disease.

• When one of your heart valves malfunctions, there will be no choice but to replace it with an artificial heart valve.

ECG• The machine that records the patient’s

heart abnormalities and problems is called an electrocardiograph.

• An ECG is a medical test that detects heart abnormalities and problems by measuring the activity generated by the heart as it contracts.

• This machine records the electrical activity of the heart muscle and displays this data as a trace on a screen or on paper, to be interpreted by the medical practitioner.

• Doctors would recommend an ECG for patients who may be at risk of heart disease because of their family genes, of heart disease, or because they smoke, high cholesterol or high blood pressure.

Artificial Blood

• Artificial blood is a blood substitute, a substance used to mimic and fulfill some functions of biological blood.

• They are usually in the oxygen-carrying sense.

• They aim for a quick blood transfusion which is transferring blood from one person into another.

• The main categories of such oxygen-carrying blood substitutes are hemoglobin based oxygen carriers and perfluorocarbon-based oxygen carriers (PFBOCs).[1]

Unfortunately, oxygen transport has been very difficult to reproduce.
