Have you heard of an alternative technique to standard cardiopulmonary resuscitation (CPR)?  The alternative method is for chest compressions only (and at a rate of 100 per minute)  without pausing to administer mouth-to-mouth breathing to the victim.  A new emphasis is showing up in many places for this simpler method.

Arguments for the growing support for the alternative method center upon the greater likelihood for bystanders to assist than with the more complicated standard CPR method.  The relative simplicity and lack of oral contact are probably factors in this.  Too, some proponents of the alternative method cite greater effectiveness because chest compressions are not cyclically interrupted for administration of mouth-to-mouth breathing.

The RV Service Net’s April 2010 Bulletin included an article by the same title as this notice.  The hot link to the YouTube video’s URL was lost in the printing.  This is a clear dramatization of administering rapid continuous chest compression as an alternative to standard CPR,  http://www.youtube.com/watch?v=E5huVSebZpM

The Science Daily website provides a nice overview of the issues in this release,  http://www.sciencedaily.com/releases/2009/11/091115191015.htm

The American Heart Association has issued a statement endorsing the hands only cpr alternative method,  http://americanheart.mediaroom.com/index.php?s=43&item=377

The American Red Cross supports the hands only cpr alternative method, http://www.redcross.org/portal/site/en/menuitem.94aae335470e233f6cf911df43181aa0/?vgnextoid=bd39244b6949b110VgnVCM10000089f0870aRCRD

American Heart Association (AHA) and American Red Cross (ARC) BOTH state the different CPR technique is not a replacement for standard CPR.  Standard CPR should be administered by personnel properly trained and who are prepared for and comfortable with administering mouth-to-mouth breathing.

AHA and ARC recommend continuous chest compression is advised for bystanders who are not trained in standard CPR, or anyone not comfortable with administering mouth-to-mouth breathing during CPR.  And they both recommend everyone obtaining training in CPR.

If you see someone collapse and they are not responsive, AHA, ARC, and Mayo Clinic all clearly state you should administer either the simpler hands only CPR or standard CPR, according to your training.

Even if you are not trained, at least administer the hands only CPR, with continuous chest compressions at a rate of 100 compressions per minute.  You may save a life.

I picked up these numbers today while investigating info on tuning my father-in-laws cb antenna.  The author probably has good basis for his report and provides an interesting comparison of antenna length to power.  While we were at AES in Orlando a couple of months ago during our Club’s Ham-A-Rally I was shopping some antennas. The sales hams in the store told me the obvious, length makes a difference.

Here are some numbers from an article entitled, “<How does an antenna size affect my CB radio?” to paint the picture a little more precisely:

• If you put 4 watts into a four-foot antenna, you will get the same power out of that antenna as if you were putting 2 watts into a 102-inch whip.

• If you put 4 watts into a 3-foot antenna you will get the same power out as if you wre putting about 1.5 watts into a 102-inch whip.

• If you put 4 watts into a 7.5 inch antenna on a hand held CB, it would put out as much power as a third of a watt into a 102-whip.

• If you put 4 watts into a 102-inch whip antenna, it is the same output as if you put 11 watts into a 3-foot whip.

• If you put 4 watts into a 102-inch whip antenna,, it is the same as if you put 14 watts into a 28-inch antenna.

• If you put 4 watts into a 102-inch whip antenna, it is the same as if you put 54 watts into a 7.5 antenna.
