What Is The Specific Method Of First Aid On Site When An Electric Shock Occurs

1. Immediate Power Disconnection: The First Priority in Rescue

Key Methods for Power Disconnection

• Use Power Switches/Plugs: If a main power switch or plug is nearby, turn off the switch or unplug the device to cut power. Note: Standard light switches (e.g., pull-cord switches) only disconnect one wire and may not target the live (phase) wire—never assume power is fully 切断 using such switches, as emphasized in CHH Power’s safety manuals.
• Insulated Object Separation: If the victim is in direct contact with a live wire and switches are unavailable, use non-conductive tools (e.g., wooden sticks, bamboo poles, or insulated gloves—standard in CHH Power’s on-site first-aid kits) to push the wire away from the victim.
• Insulated Tool Cutting: For inaccessible switches, use insulated tools (e.g., electrician’s pliers with insulated handles, wooden-handled axes) to cut the live wire.

Critical Safety Notes (CHH Power Emergency Standards)

• Prevent Secondary Injury: After disconnection, the victim’s muscles will relax, potentially causing falls—especially at heights. CHH Power requires rescuers to stabilize the victim during disconnection to avoid fractures or head injuries.
• Rescuer Safety: Always use insulated equipment to avoid becoming a secondary victim. CHH Power’s on-site safety audits regularly check the condition of insulated tools to ensure reliability.

2. Rapid Assessment: Simple Diagnosis for Post-Shock Conditions

Step 1: Move the Victim to a Safe Location

Step 2: Check Vital Signs

• Respiration: Observe chest/abdominal movement; place a hand near the victim’s nostrils to feel airflow. Absence of movement or airflow indicates respiratory arrest.
• Pulse & Heartbeat: Palpate the carotid artery (neck) or femoral artery (groin)—these superficial large arteries are easy to feel. A pulse confirms a heartbeat. For further verification, listen for heart sounds over the precordial area (chest center).
• Pupil Reaction: The pupil acts as a brain function indicator. In normal states, pupils adjust to light; in apparent death, severe brain hypoxia causes fixed, dilated pupils (unresponsive to light).

3. Targeted Treatment Based on Assessment Results

• Conscious but Fatigued: Victims may experience dizziness, palpitations, cold sweats, or nausea. CHH Power advises immediate on-site rest to reduce cardiac strain. For severe symptoms, arrange safe transport to a medical facility with continuous monitoring.
• Unconscious but with Breathing/Heartbeat: Keep the victim supine in a well-ventilated area; maintain warmth and closely monitor vital signs. Prepare for artificial respiration or chest compressions if their condition deteriorates. Notify emergency services immediately and transport via stretcher, with ongoing checks for sudden apparent death.
• In Apparent Death: Initiate emergency resuscitation at once:
  • Cardiac Arrest Only: Perform external chest compressions to maintain blood circulation.
  • Respiratory Arrest Only: Administer mouth-to-mouth artificial respiration (detailed below).
  • Both Arrests: Combine chest compressions and artificial respiration. Continue resuscitation without interruption—even during transport to the hospital—until breathing and heartbeat are restored. CHH Power’s training stresses that stopping rescue prematurely is a leading cause of preventable death in such cases.

4. Mouth-to-Mouth Artificial Respiration: CHH Power’s Recommended Technique

1. Prepare the Victim: Lay them supine; untie collars and loosen clothing. Turn their head to the side, open their mouth, and remove dentures, blood clots, or vomit to clear the airway—critical for avoiding obstruction, per CHH Power’s guidelines.
2. Position the Head: Kneel beside the victim. Use one hand to pinch their nose shut (preventing air leakage) and press their forehead to tilt the head back. Place the other hand under their neck to lift the head, ensuring the tongue does not block the airway.
3. Administer Air: Take a deep breath, seal your mouth over the victim’s mouth (or nostrils if the mouth is inaccessible), and blow air gently. Observe if the chest rises—this confirms effective airflow.
4. Allow Exhalation: After blowing, turn your head away and release the hand pinching the nose. Let air escape naturally from the victim’s lungs; watch for chest deflation and listen for exhalation sounds.
5. Repeat Rhythmically: Perform 12 breaths per minute (one breath every 5 seconds), maintaining a steady pace until the victim regains spontaneous breathing.
