  • Valor7: I could have worded that better, we talked details, options, the pros and cons of each, in  order to arrive at the best ballot language to present to the voters. Hope that makes this clearer.

  • Valor7: Yes and no. We talked details and options until we were blue in the face but I never heardbring it over, it was always the time was not right for the issue to pass. Glad to see the time in now right and I for one shall vote yes on the ballot. I would urge all others to do the sameour county is busting at the seams crimewise and no matter how many bad guys we send off there always seems to someone to replace them. The Sheriff's Office needs the help.

Chest presses, not breaths, help CPR By MARILYNN MARCHIONE, AP Medical Writer
1 hour, 10 minutes ago
 


Chest compression not mouth-to-mouth resuscitation seems to be the key in helping someone recover from cardiac arrest, according to new research that further bolsters advice from heart experts.

A study in Japan showed that people were more likely to recover without brain damage if rescuers focused on chest compressions rather than rescue breaths, and some experts advised dropping the mouth-to-mouth part of CPR altogether. The study was published in Friday's issue of the medical journal The Lancet.

More than a year ago, the        American Heart Association revised CPR guidelines to put more emphasis on chest presses, urging 30 instead of 15 for every two breaths given. Stopping chest compressions to blow air into the lungs of someone who is unresponsive detracts from the more important task of keeping blood moving to provide oxygen and nourishment to the brain and heart.

Another big advantage to dropping the rescue breaths: It could make bystanders more willing to provide CPR in the first place. Many are unwilling to do the mouth-to-mouth part and become flummoxed and fearful of getting the ratio right in an emergency.

Sudden cardiac arrest when the heart suddenly stops beating can occur after a heart attack or as a result of electrocution or near-drowning. It's most often caused by an abnormal heart rhythm. The person experiencing it collapses, is unresponsive to gentle shaking and stops normal breathing.

In the new study, researchers led by Dr Ken Nagao of Surugadai Nihon University Hospital in Tokyo analyzed 4,068 adult patients who had cardiac arrest witnessed by bystanders. Of those, 439 received chest compressions only from bystanders, and 712 received conventional CPR compressions and breaths.

Any CPR attempt improved survival odds. However, 22 percent of those who received just chest compressions survived with good neurological function compared with only 10 percent of those who received combination CPR.

"Eliminating the need for mouth-to-mouth ventilation will dramatically increase the occurrence of bystander-initiated resuscitation efforts and will increase survival," Dr. Gordon Ewy, a cardiologist at the University of Arizona College of Medicine in Tucson, writes in an accompanying editorial.

A big caveat: The combination CPR in the Japanese study was given according to the old guidelines of 15 presses for every two breaths, not the 30 presses recommended now.

The American Heart Association said the study supports a focus on chest presses, but the association does not expect its advice to change. It recommends that bystanders provide compression-only CPR if they are "unwilling or unable" to do mouth-to-mouth breathing at the same time and for emergency dispatchers to give instructions on that.

The association wants to see survival results from programs that use compression-only CPR for cardiac arrest.

"It is important to note that victims of cardiac arrest from non-cardiac causes, like near-drowning or electrocution, and almost all victims of pediatric cardiac arrest benefit from a combination of rescue breathing and chest compressions," a heart association statement says.

More than 300,000 Americans die from cardiac arrest each year. About 75 percent to 80 percent of all cardiac arrests outside a hospital happen at home, and effective CPR can double a victim's chance of survival.

Roughly 9 out of 10 cardiac arrest victims die before they get to the hospital partly because they don't get CPR.

I just called Paula Wyatt, one of our first responders but she isn't home at the moment.  I left a message on her machine asking her to call me back and let me know.  I will post as soon as I hear from her.

Rick, that is for laypersons. Not trained medical people. Laypersons frequently hesitate to do mouth-to-mouth and they do not have the equipment we have to breathe for an person not breathing. So studies show that chest compressions will help. But this is temporary and not ideal. Most people without a lot of training cannot do adequate ventilation anyway. They can't tolerate the things in the way, vomit, saliva and so on. So they rarely move any air in anyhow. They do not know how to open the airway and clear it and maintain adequate ventilation. That is not the case with us, we place tubes in, use a bag-valve-mask, etc. and breathe for the person.

I agree, but also, if the only thing you can do is chest compressions, then do it. I once knew an 80 year old wife whose husband had a heart attack. She put him in the car and drove him to the hospital. The entire time driving she was "beating" on his chest, calling him names and telling him that he's not supposed to die. When they got to the ER they revived him fully but they said that if she hadn't been beating on his chest, his heart would have stopped completely and he would have died.

I'm not sure however why, "22 percent of those who received just chest compressions survived with good neurological function compared with only 10 percent of those who received combination CPR". Your body needs oxygen, your blood needs oxygen otherwise it can't survive.
