CPR - hands only is now okay

Heart attack? Need to do CPR? Hands only is okay

The new cardiopulmonary resuscitation (CPR) guidelines ideally look for pressing on the person's chest and skipping or delaying the mouth-to-mouth breaths.

If you do not have the training then the hands-only portion is at least as effective in the first few minutes after cardiac arrest as the usual CPR and is way better than doing nothing at all.

So if you don't know how to do the standard CPR or you are not comfortable putting your mouth on someone else's then do the hands-only version.

Call 911 right away. Someone can give you quick and easy instruction on just dong the chest compressions.

Pumping the chest before giving breaths is also recommended for newborns and children.

There is updated recommendations for first aid, including how bystanders should treat snake bites, jellyfish stings, and allergic shock.

The two groups now recommend putting a pressure bandage on any venomous snake bite rather than using suction, which may worsen the wound and is unlikely to remove much venom.

Apply vinegar and follow with hot water to help with jellyfish stings by neutralizing the venom and reducing pain, the guidelines say.

The treatment recommended for allergic shock, called anaphylaxis, is to give an epinephrine injection from a prescribed auto-injector. If help is delayed and the victim doesn't respond "after a few minutes," a second injection can be given.
