When it comes to learning CPR, skip YouTube: A study published in the journal Emergency Medicine Australasia found only 11 percent of uploads is up to medical snuff.

Researchers searched the online video service for all videos tagged with CPR, cardiopulmonary resuscitation, BLS, and basic life support. They excluded any videos that were advertising ploys, off-topic, and posted before 2011. Using the International Liaison Committee on Resuscitation’s 2010 guidelines as a reference, researchers analyzed and rated how many videos properly demonstrated CPR. Since, you know, it is still the Internet.

They found a mere 11.5 percent of 209 CPR videos met health guidelines regardless of when they were uploaded. “Although well-designed videos can create awareness and be useful as tools in training, they can never replace hands-on instruction from a properly qualified health practitioner," Paul Middleton, study author and fellow of the Australasian College for Emergency Medicine and chair of the Australian Resuscitation Council NSW, said in a press release. "People wanting to learn CPR and BLS skills should seek out a properly accredited training course."

One such resource is the American Heart Association (AHA). The AHA reported 70 percent of Americans feel helpless during a cardiac emergency, but anyone can — and should — learn CPR, given four out of five cardiac arrests happen at home. Additionally, a study published in Circulation found people who view a correct CPR video are significantly more likely to attempt life-saving resuscitation.

The AHA recommends learning hands-only CPR because it doesn’t require giving mouth-to-mouth. All people have to do is dial 911, place the heel of one hand in the center of the recipient’s chest, and with their other hand on top of that one, pump hard and fast until the medics arrive.

Remember to pump at no less than 100 beats per minute (BPM). Or if you can’t, simply cue up the AHA’s “Save A Life” playlist on Spotify. Every song included is the required BPM, including tracks from Beyonce, Michael Jackson, and Justin Timberlake.

Hands-only CPR, according to the AHA, has been shown to be as effective as CPR involving mouth-to-mouth. Spotify now streams free for non-premium users, so really, there’s no excuse.
