When you’re diving, help isn’t always just a phone call away. Whether on a boat, at a remote dive site, or underwater, knowing CPR and First Aid can make a life-saving difference.
Understanding CPR and First Aid Do’s & Don’ts helps divers respond quickly, protect their buddies, and handle emergencies with confidence above and below the surface.
The Importance of Learning CPR and First Aid in Scuba Diving
In scuba diving, emergencies can happen far from medical help. Learning CPR and First Aid provides scuba divers the needed skills to act fast, protect their dive buddies, and manage critical situations until professional help arrives. When you learn CPR and First Aid, this reflects on your dives:
- Increases safety in the water.
- Helps prevent further injury.
- First aid saves lives.

CPR and First Aid Do’s
These simple best practices help divers respond calmly, act correctly, and give effective care when it becomes the difference between life and death.
Ask for Permission: Good Samaritan Laws Require Consent
Many countries have Good Samaritan laws that legaly protect bystanders who step in to give life-saving assistance. To qualify for protection, the rescuer should ask for consent—if the person can’t respond, consent is assumed.
Turn An Unconscious Person Onto Their Side: Unless You Think There May Be a Neck Or Spine Injury
Turn the victim on their side to prevent them from choking on fluids (like blood or vomit) that may collect in their airway.
Replace a Knocked-out Tooth: It’s a Priority to Protect the Root
If the patient is still breathing and communicating, put the tooth back in its socket. In case of having a dirty tooth, rinse it in a gentle way and try not to touch the root as you can. Avoid putting the tooth in water (because this can damage the root).
If the tooth failed to stay in its socket, put it in the mouth of the patient, or in a glass of milk. It is highly recommended in this case to ride the patient to emergency dental care within 30 minutes.
Enroll in a Hands-on CPR Course: It isn’t Enough to Get an Online-only Training
Just like lifting weights or dribbling a ball, CPR is also a physical skill. Good technique is important, and an experienced local instructor can provide you with useful tips and guidance.
Take First Aid And Cpr Refresher Training: We All Forget Things Over Time
Everyone, including doctors and nurses, must take s refresher training to refresh their CPR skills every couple of years. Your EFR instructor can give you a reference card, but in emergencies, wouldn’t you want your life-saving skills ready without thinking?

CPR and First Aid Don’ts
Knowing CPR and First Aid don’ts is just as important as knowing the right steps in CPR and first aid. These bad acts include:
Don’t Give Aid Immediately: Call Emergency Services First
It takes around 7-14 minutes for emergency medical services to arrive at the scene of accident. Make sure trained professionals are on the way before assisting.
Avoid Bending Your Elbows When Performing Cpr: This Saves Precious Energy
Performing CPR using only the muscles of your arm is exhausting. Keep your arms straight to engage the muscles of your back and shoulder, this also leverage your body weight. Recruiting more muscles enhances your ability to perform chest compressions in a correct way, in addition to improving endurance.
Don’t Rock Back And Forth While Doing Chest Compressions—It Tires You Out And Reduces Effectiveness
Providing life-saving chest compressions in a proper way isn’t difficult, but it can tire you out. During your CPR class, you’ll practice on a mannequin which is specially designed for such training and receive tips from your instructor on how to conserve energy.
