Scuba diving, while a rewarding experience, carries inherent risks. One of the most serious emergencies is encountering an unconscious diver. Responding effectively requires immediate action, a calm demeanor, and a thorough understanding of appropriate first aid procedures. This article details the crucial steps to take when faced with this critical situation. Remember, prioritizing the diver's safety and seeking professional medical assistance are paramount.

Assessing the Situation: The First Critical Steps

Before initiating any first aid, ensure your own safety. If the environment is hazardous (strong currents, poor visibility, dangerous marine life), prioritize your safety and summon help before approaching the unconscious diver. Once you've secured a safe approach, perform a quick assessment:

1. Check Responsiveness:

Gently shake the diver and loudly shout their name. Look for any response, even the slightest movement. This determines the level of urgency and guides your subsequent actions.

2. Check for Breathing and Pulse:

If there's no response, immediately check for breathing. Look, listen, and feel for breaths for no more than 10 seconds. Simultaneously, check for a pulse at the carotid artery (neck) or femoral artery (groin). Absence of breathing or a pulse indicates cardiac arrest, requiring immediate CPR.

3. Assess the Scene:

Observe the environment for clues that might explain the unconsciousness, such as:

• Obvious injuries: Cuts, bruises, or bleeding.
• Equipment malfunction: A broken regulator, empty air tank, or entangled equipment.
• Water conditions: Strong currents, cold water, or hazardous marine life.
• Depth of unconsciousness: Was the diver deep when they lost consciousness? This might indicate decompression sickness.

Documenting these observations is crucial for medical professionals.

Initiating Rescue Breathing and CPR:

If the diver is not breathing or has no pulse, begin CPR immediately. The survival rate decreases significantly with each passing minute without CPR.

1. Rescue Breathing:

If there is no pulse, but the diver is breathing shallowly or irregularly, begin rescue breathing. This involves giving breaths to help maintain oxygen levels in the blood.

• Head-tilt-chin-lift maneuver: Carefully tilt the diver's head back and lift their chin to open their airway.
• Mouth-to-mouth or mouth-to-mask resuscitation: Give rescue breaths, ensuring a visible chest rise with each breath.

2. Chest Compressions:

If there's no pulse, combine rescue breathing with chest compressions to perform CPR. The current recommended technique emphasizes chest compressions as the priority. The compression rate should be 100-120 per minute, with a depth of at least 2 inches (5 cm). Continue CPR until:

• Professional medical help arrives.
• The diver shows signs of recovery (breathing spontaneously and regaining consciousness).
• You are physically exhausted and need to be relieved.

Considering Spinal Injury:

Always assume a potential spinal injury. Unconsciousness following a diving accident can indicate trauma to the spinal cord. Improper handling can worsen the injury, leading to paralysis or death.

1. Stabilization Techniques:

Before moving the diver, carefully stabilize their neck and spine. Use manual stabilization, or if available, an appropriate backboard and cervical collar. Moving the diver should only be undertaken by trained personnel capable of maintaining spinal alignment.

2. Gentle Handling:

When moving the diver, use a method that minimizes spinal movement. Multiple rescuers should work in coordination to maintain a consistent spine alignment throughout the entire process. In water, this is extremely challenging and requires specialized training and equipment.

Addressing Specific Conditions:

The cause of unconsciousness can influence subsequent first aid actions. Consider these possibilities:

1. Drowning:

If the unconsciousness is related to drowning (water inhalation), focus on clearing the airway and performing rescue breathing and CPR.

2. Decompression Sickness (DCS):

If the diver was at significant depth before losing consciousness, DCS should be suspected. DCS, also known as "the bends," involves the formation of gas bubbles in the blood and tissues. Treatment involves recompression in a hyperbaric chamber. Do not attempt to treat DCS yourself. Your primary focus should be providing basic life support and quickly contacting emergency medical services, emphasizing the possibility of decompression sickness.

3. Air Embolism:

This is a serious condition where air bubbles enter the bloodstream, usually from a rapid ascent. Symptoms may include chest pain, shortness of breath, and unconsciousness. Air embolism is a life-threatening emergency requiring immediate medical attention and hyperbaric treatment.

4. Carbon Monoxide Poisoning:

This can occur if the diver breathes in exhaust fumes from a boat or other source. Symptoms might include headache, dizziness, nausea, and unconsciousness. Provide fresh air and immediate medical attention.

5. Cardiac Arrest:

This requires immediate CPR and defibrillation if available.

Post-Rescue Procedures:

Once basic life support is provided or the diver regains consciousness, continue to monitor vital signs and provide appropriate care. This includes:

• Maintaining body temperature: Prevent hypothermia by covering the diver with blankets or clothing.
• Monitoring breathing and pulse: Regularly check for changes in vital signs.
• Providing oxygen: If available, administer oxygen to aid recovery.
• Continuing spinal stabilization: Maintain spinal alignment if a spinal injury is suspected.
• Transporting the diver: Safely transport the diver to a medical facility using appropriate methods.

The Role of the Dive Buddy:

The dive buddy system is crucial for diver safety. In case of an emergency, the buddy plays a vital role in:

• Immediate assistance: Providing support, initiating rescue breathing, and summoning help.
• Assessment of the situation: Determining the potential cause of the unconsciousness and relaying information to emergency responders.
• Safe retrieval of the diver: Helping bring the unconscious diver to the surface using appropriate techniques and equipment.
• Maintaining communication: Relaying information to emergency responders and any shore-based support.

Regular dive buddy training is essential for effective emergency response.

Conclusion:

Responding to an unconscious scuba diver requires swift action, precise techniques, and a calm approach. This article outlines the crucial steps involved. However, formal first aid and CPR training are absolutely essential for anyone involved in scuba diving. This knowledge enables safe and effective rescue procedures, greatly improving the chances of survival for the unconscious diver. Remember, prevention is key. Always practice safe diving habits, maintain proper equipment, and be mindful of the risks involved. A proactive approach, coupled with comprehensive training, is the best way to ensure the safety and well-being of all divers. Prioritize safety, seek professional help immediately, and remember that quick and decisive actions can mean the difference between life and death.
