Theory- 4 :- First Aid & Artificial Respiration

1. First Aid Essentials in Hardware Labs

First Aid is the immediate medical assistance provided to an injured individual before professional medical help arrives. In hardware and networking environments, common hazards include electrical shocks, thermal burns, and cuts from sharp chassis edges.

The "3 Cs" Action Plan

1. CHECK: Ensure the area is safe from live currents before touching the victim.
2. CALL: Contact emergency services (108/112) immediately.
3. CARE: Administer first aid or CPR based on the victim's condition.

Essential Kit Items

• Antiseptic: Betadine / Savlon
• Burn Ointment: Burnol / Silverex
• Dressings: Sterile gauze, cotton, adhesive tape
• Tools: Bandage scissors, tweezers, gloves

2. Electric Shock Response Workflow

Electric Shock Emergency Flowchart

1. ACCIDENT: Victim in contact with live current

🢃

2. ISOLATE: Turn off Main Switch OR use a dry wood/plastic pole to push wire away. Never touch with bare hands!

3. ASSESS: Check for Breathing and Pulse

🢃

✔ BREATHING NORMAL:
• Place in recovery position (on side)
• Loosen tight clothing
• Keep warm & await help

✘ NOT BREATHING / NO PULSE:
• Start CPR / Artificial Respiration immediately!
• Brain damage starts in 4–6 mins without oxygen.

3. CPR & Artificial Respiration Steps

Method	How to Perform	Best Used For
Mouth-to-Mouth	Tilt head, pinch nose, blow into mouth until chest rises (10–12 breaths/min).	Standard direct method for non-breathing victims.
Holger-Nielsen	Lay face down. Press shoulder blades to exhale; pull elbows up to inhale.	When mouth/face has severe burns or chemicals.
CPR	Compress chest 2 inches deep at 100–120 bpm. Ratio: 30 Compressions : 2 Breaths.	When both breathing and pulse have stopped.

Quick Key Takeaways

• Isolate current first: Never touch a victim connected to a live wire.
• Act in 3 Minutes: Brain damage occurs rapidly without oxygen.
• CPR Ratio: 30 Chest Compressions to 2 Rescue Breaths.
