| Consider the following statements about Biomedical Technologies. |
| 1. Balloon pump technique is used, when the pumping action of the cardiac ventricle temporarily become too poor to maintain effective profusion of tissues and organs with blood and need support. |
| 2. Electrocardiography is a valuable non-intensive tool for imaging heart and surrounding structures. |
| 3. Cryopreservation technique involves the use of tissues taken from humans and other animals for the purpose of reconstructive surgery. |
| Which of the statements given above are correct? |
A) 1 and 2
B) 1 and 3
C) 2 and 3
D) All of these
Correct Answer: D
Solution :
[d] Biomedical Technologies bridge the medical and engineering techniques providing an overall enhancement of healthcare. Balloon pump supports the ventricles by increasing the blood supply to the heart muscles and making it easier for the ventricle to pump. The balloon pump is an instrument, which is used to assist the heart for hours and days, till the patients own heart remains its normal function. Electrocardiograph can be quite helpful in establishing a specific diagnosis and estimating the severity of various cardiac diseases. ECG is also used to evaluate cardiac chamber size, wall thickness etc. In cryopreservation, cornea transplantation has been done with great success. It is for this reason that cornea can be preserved easily. Cryopreservation of vital organs like kidney, liver and heart are highly complicated and may evoke immune rejection.
