Equipment & Devices
Required first-aid equipment at facilities
- AED
- Cervical collars (paediatric and adult)
- Water-rescue immobilisation board
- Vacuum splints, Kramer splints
- Pocket mask, BVM (adult and paediatric)
- Oxygen cylinder + flow regulator
- Mechanical aspirator
- OPAs sizes 2, 3, 4
- O₂ masks (simple, with reservoir for adults and children)
- Nasal cannula
- Suction catheters
- Bandages, gauze, splints, foils, rescue scissors
Oxygen — duration calculation
Time (min) = (cylinder pressure − safety pressure 15 bar) × volume / flow rate (L/min)
Oxygen delivery devices
- NASAL CANNULA: 1–6 L/min → up to ~40% O₂. Only if patient breathes through nose effectively.
- SIMPLE MASK: 4–10 L/min → 35–60% O₂
- MASK WITH RESERVOIR: 10–15 L/min → 60–95% O₂. Reservoir bag must stay at least half full.
- BVM with O₂ reservoir: 10–15 L/min during ventilation
O₂ safety
- Cylinder on solid base, protected
- NEVER use lubricants on O₂ equipment
- NEVER near open flame
- Regular service of cylinders and valves
Pocket mask
Plastic mask with one-way valve and filter. Place over nose and mouth. Pinch with thumbs and index, three remaining fingers under jaw to keep airway open. 1-second breaths via mouthpiece, watch chest rise. Can connect O₂ at 15 L/min.
Bag-valve-mask (BVM)
- Choose mask size: adult #5 (small adult #3-4), child #2, infant #1
- BVM size: adult 1500–2000 ml, child 1000 ml, infant 500 ml
- Mask grip: thumb + index forming a "C", three fingers under jaw to lift it
- Squeeze bag for 1 second — chest rises
- O₂ at 10–15 L/min via reservoir attachment
- Common errors: poor mask seal, incorrect airway position, wrong tidal volume
Oropharyngeal airway (OPA)
- Size: from corner of mouth to the angle of the jaw, OR earlobe to corner of mouth
- Insert with concave side toward the palate, then ROTATE 180° as you advance
- For children/infants: do NOT rotate — use a tongue depressor and insert directly with concave down
- Remove if gag reflex returns
- Useful for unresponsive trauma patients where head-tilt is contraindicated
AED — automated external defibrillator
- Two types: automatic (delivers shock automatically) and semi-automatic (you press the shock button)
- Pad placement: right side under collarbone + left mid-axillary line
- Alternative: front-back if pads might touch (small chest, pacemaker)
- Dry the chest before pad placement
- Do not place over breasts, stickers, or pacemaker
- Paediatric pads / paediatric mode for under 8s
- After "shock advised": "Everyone clear!" → press button → resume CPR immediately
Pulse oximeter
Clip-on sensor on a finger. Normal SpO₂: above 94%. Chronic lung disease patients: 88–92% may be normal. Inaccurate readings if skin is cold, wet, dirty, damaged, or poor circulation.
Cervical collar
- Sized: distance from lower side of neck to lower edge of chin in neutral position
- Always TWO rescuers: one holds C-spine manually, the other sizes and applies
- Place rear part first, then front under chin, fasten the strap
- Patient must be able to breathe, speak, open mouth normally
- A cervical collar is NEVER enough alone — always combined with backboard
Water immobilisation board
Buoyant; concave upper surface; coloured straps; for spinal patient extraction from water and as a long board on land. Length 183 cm, max 182 kg.
