Cardiac Arrest Clinical Trial
In this study, we want to find out whether the recognition of cardiac arrest using a smart watch is feasible or not. If this idea is possible, the recognition of cardiac arrest using the smart watch is easy and fast to the witness, like a general person. By using the smart watch, the emergency response system for cardiac arrest and the bystander CPR or BLS is beginning earlier than using conventional cardiac arrest recognition method in field.
In Korea, an out-of-hospital cardiac arrest (OHCA) was occurred twenty thousand person per
year, and among them sixty percent was occurred in their home. We already knew that a
survivor rate and neurological outcome of OHCA patient has a close relation with initial
emergency management in field, like a bystander cardiopulmonary resuscitation (CPR), Basic
Life Support (BLS), etc. However, in Korea, a witness almost did not the bystander CPR or
BLS in field until highly trained rescuers arrived there. So, total survivor rate is just
2.4 % irrespective of neurologic outcome in Korea.
Generally, in Korea, a beginning of the bystander CPR progress throughout dispatcher's
instruction of emergency response system. This system for OHCA patient activate only when
the witness recognize cardiac arrest and call the emergency response system. Therefore,
cardiac arrest recognition by the witness is very important.
However, a conventional recognition of cardiac arrest in field is often difficult, because
there are no monitoring devices, healthcare providers. The conventional recognition method
of cardiac arrest is that it is firstly to check mental status, secondly check pulse on
patient's carotid artery and self-respiration. This method is too difficult for the witness,
especially general persons. Even, it is difficult for an emergency physicians, too.
Consequentially, the recognition of cardiac arrest by the witness is generally delayed, a
golden-time is running out until highly trained rescuers arrive there. An average arrival
time of highly trained rescuers is eight to ten minutes. A hypoxic brain damage is begin
from four minutes after cardiac arrest. As a result, this delayed time is already passed
four minutes after cardiac arrest. So, the survivor rate and the neurologic outcome are not
good enough.
In this study, we want to find out whether the recognition of cardiac arrest using a smart
watch is feasible or not. If this idea is possible, the recognition of cardiac arrest using
the smart watch is easy and fast to the witness, like a general person. By using the smart
watch, the emergency response system for cardiac arrest and the bystander CPR or BLS is
beginning earlier than using conventional cardiac arrest recognition method in field.
