new YORK (Reuters Health) – when a patient performs a
cardiac arrest in a hospital, doctors and nurses him
do cardiopulmonary resuscitation (CPR), which includes compressions
chest that they need to be sufficiently deep as
to carry blood from the heart to the rest of the body.
But if the rescuer is of short stature and the victim is
in the hospital bed, a problem arises: is difficult you can
achieve the necessary height to press the chest
correctly the chest, by what the rescuer should depend on
the force of the upper part of the body to be able to
perform them.
Sounds logical to offer rescuers a step
is a useful tool.
However, equip all hospital beds with a
step would require an expenditure, as believed Dr. Dana P.
Edelson, author of doctor of the University of Chicago Center
a new study principal.
So that hospitals would need to first know if
the use of steps would improve the quality of the maneuvers of
RCP.
Then, the team of Edelson asked 50 professionals
of its Center, all trained in CPR, which conducted the
chest compressions on a mannequin. Each made series of
two minutes standing on the floor of the room and then
on a step of 23 centimeters (cm) in height.
The mannequin had a sensor that recorded the depth of
compressions and other characteristics to determine the
quality CPR.
Published in the journal Resuscitation, the team that the
best results with the step were registered with the
rescue workers of less than 1.70 m tall. On average, the
depth of his thrusts grew 1 cm, suggesting that
rescuers of stature “would gain a great benefit”
If used a step.
On the other hand, the depth of compressions of the
highest rescuers increased only two tenths of a
centimeter due to overwork in the inclination of the body.
Between two compressions, the rescuer should secede as
enough of the patient’s body to the chest “rewind”
and the heart to pump blood, said again
Edelson. A person high stop at a step costs it more
carry his weight backwards.
“The effect of the inclination of the body surprised us a
“”
short”, said Edelson.
Based on these results, the team believes that it would be
“reasonable” than rescuers with less than 1.70 meter of
height using a step. Regardless of that, Edelson
recalled that they should always lower the hospital bed.
Given that the trial was conducted with Dummies, it is unknown if
the use of steps would save lives. But the authors
ensure that the depth of chest compressions is the
that matters.
During a cardiac, arrest the heart stops pumping blood
to the rest of the body. Often, this happens by a disorder of the
beats known as ventricular fibrillation.
CPR chest compressions allow the blood
and oxygen continue circulating around the body; but the only
way that the heart back to pump without help is with the
use of a defibrillator or certain drugs.
Even so, cardiac arrest often fatal: barely survives
about 17 percent of hospital patients to
suffer.
