Perhaps one of the most valuable pieces of medical equipment to own is the defibrillator. air purifier motor
Defibrillation is the treatment for life-threatening cardiac
arrhythmia. In fact, many schools and universities are now installing
this equipment in their buildings in order to save lives. Owning this
piece of equipment is something that everyone should consider,
especially if there is a history of heart disease in one's family.
Defibrillators
administer a therapeutic amount of electric current to the involved
heart tissue. The electrical shock depolarizes the heart muscle. This
stops the abnormal heartbeat. After the irregularity has been ended, the
human body's natural pacemaker restarts the normal heart beat pattern.
Many
kinds of defibrillators are marketed today. These include implanted and
external defibrillators. These machine tend to be simple to use, so
that bystanders without medical training can employ them during an
emergency. Indeed, these defibrillators must be used quickly, because
there is very little time in which the patient's cardiac rhythm can be
restored before irreversible damage is done.
These devices were
discovered in 1889, when two physiologists from Switzerland discovered
that small electrical shocks could induce ventricular fibrillation in
dogs, and that subsequent charges would reverse the condition. It was
almost 50 years later that the experiment proceeded on humans.
The
technology of medical defibrillators has advanced significantly since
their first introduction. Originally, the machines were much more bulky
and relied on alternating current to supply the electrical shock. Today,
the machines rely on direct current, which allows for the smaller size,
and also requires less energy to operate. The machines are even small
enough now that they are portable, and can be transported and used in
ambulances.
The waveform of the traditional defibrillator is also
changed as an impact of technology. When the defibrillator machine was
first invented, electrical charge was applied in the Lown waveform.
Until the truncated waveform was shown equally effective which required
lower energy to deliver the current, the traditional standard was used.
It
is necessary to possess and know the operational technique of a medical
heart machine if I or my family have a history of heart disease. It
would be very sad if our dear one's life is lost by not having a medical
heart machine that could be used at the time of cardiac arrhythmia.
Several people are using these machines at home as the prices have
reduced to safe guard their families.
