How Biomedical Informatics have Helped the Diseased and Ailing

Thanks
to the advances made by Biomedical scientists using informatics, millions of
people who are having ailments that earlier were not treatable, or not having a quality
of life after disablement, are finding their lives better, because of this new
topic Biomedical informatics.

The
field of Biomedical informatics is as yet vast open, and knows no boundaries.
Yet, within what has become known, and what has been tried, many people who
were disabled, and immovable, such as those with neural failures, and unable to
move their torsos below their waists, can now use wheel chairs which are fitted
with computing devices, and controlled by the people by a wireless or a
microphone near their mouth to make the wheelchair move in the direction they
want.

Those
who have had angina, a form of a heart attack, but less so, with dead tissue
surrounding the heart muscle, which sends weak, instead of the normal strong
signals to the heart, have had pacemakers installed which converts the weak, or
even nonexistent electrical  signals to
the heart to keep it beating!

Take
another example. We all know about kidney malfunctions. What is a dialysis
machine? The human body itself used to flush the kidneys on their own, and
maintain the kidneys in proper shape for excreting the wastes of the human
body. When they failed, death was a certainty. 
But today, having studied the kidney functioning, biomedical informatics
helped engineer the dialysis machine, which a kidney patient uses in the
hospital and returns after specific periods of time. Agreed that it is not
failsafe or fail proof as yet, but still hope has been given to the patient and
the family.

One
more example is that of replacing certain malfunctioning parts of the heart. A
heart attack in the previous or earlier century was a certainty for either
being bedridden, or certain death. That too has been brought into the core
function of biomedical informatics which helped engineer the heart lung
machine, by which the surgeons could operate upon the heart, and correct or
install new valves where they required replacement, and also use non open
surgeries like angiography, by introducing scopes in very less than hair-thin
tubes with clippers and lights and use a monitor to see where they were going,
and removing plaque or other material deposited inside the arteries and veins
of the heart!

There
are neural limbs available by which even those who suffered complete detachment
of their hands, or other limbs and had them reattached and are now functioning
nearly normally.  How? This is again
because of the knowledge that became available through the use of biomedical
informatics, which in turn led to prosthetic engineering.

There
are many more examples. It only requires search and awareness. Behind all this
is bioinformatics or better worded biomedical informatics.
