Task: Sentence Composition
Input (English): The news story does not mention costs, but a discussion of cost is relatively unimportant in the context of this story. The article says that CPR in any form "may double the rate of survival from cardiac rest." According to a spokesperson for the American Heart Association, this means that “we can save tens of thousands of lives.”  Later in the story the spokesperson is reported as saying that when more people use CPR in cities such as Seattle, survival rates have jumped to as high as 30%. An AHA scientific statement says cities such as Seattle have reported survival of “more than 15%.” It adds that hands-only CPR and other changes (e.g. dispatcher-assisted "telephone" CPR) could save "thousands of additional lives" every year." This mix of relative and absolute estimates suggest there is surely some real benefit to increasing the use of CPR, but the precise amount of that benefit remains a bit fuzzy. The news article explains that when CPR is performed with chest compressions only (without mouth-to-mouth resuscitation) the main harm is rib fractures induced by energetic chest thumping. Although the story mentions that "3 major studies published last year" provide evidence to support the new AHA recommendations on CPR, it fails to discuss the quality of this evidence. The studies comparing survival after bystanders’ use of hand-only vs. standard CPR are necessarily observational. The story could have explained the possible limitation of such studies. The article explains that a tiny minority of people who need CPR actually receive it. It also reassures readers that untrained bystanders can perform CPR and potentially save lives. The story does not exaggerate the problem of untreated cardiac arrest. The article cites three sources, two of them associated with the American Heart Association (which developed the new guidelines) and one an apparently independent expert who supports the guidelines. The article discusses hands-only and mouth-to-mouth resuscitation, and explains that these are used while bystanders await other options—usually treatment by emergency medical personnel and/or automated external defibrillator and, ultimately, hospital medical staff. The news article makes it clear that virtually anyone can perform hands-only cardiopulmonary resuscitation (CPR). It requires no devices or drugs. The major barrier to treatment appears to be fear–of harm to the victim or rescuer, and/or and fear of failing to perform CPR correctly. The article points out that CPR has been taught in first-aid classes for more than 40 years. There is no evidence that the story relied solely or largely on a press release.
Output (English): Hands-only CPR greatly increases survival odds
