Demand Oxygen Valve: Essential for Specific Situations

1. Introduction to the Demand Oxygen Valve

Unique Oxygen System:

The demand oxygen valve differs from standard oxygen kits and is commonly found in specialized emergency ambulances.
It's also utilized in the scuba diving world for providing 100% oxygen to individuals wearing masks, especially crucial in scuba diving accidents.

2. Components of the Demand Oxygen Valve

Key Parts:

Main True Fit Mask (Various Sizes): Ensures a secure seal around the mouth and nose, easy to take on and off.
Regulator: Automatically adjusts oxygen flow based on the user's breathing rate.
Manual Triggered Valve: Allows manual oxygen delivery when needed, useful during CPR.
Piping: Oxygen-rated white tubing.
Main Regulator with Oxygen Level Gauge: Monitors remaining oxygen supply.
Continuous Oxygen Port: Compatible with various oxygen delivery devices like pocket masks, non-rebreather masks, and nasal cannulas.
Additional Demand Valve Connection: Offers flexibility to add extra demand valves.
Flow Rate Adjustment Knob: Allows oxygen flow rates of up to 25 litres per minute, higher than standard oxygen cylinders.

3. Pin Index System

Secure Cylinder Attachment:

The Pin Index System ensures a secure connection between the demand oxygen valve and the oxygen tank.
It features two pins and a main oxygen feed, aligning with corresponding holes on the cylinder.
Proper alignment and secure tightening are essential for safe operation.
This system is crucial as it enables the demand for a higher volume of oxygen than standard medical-grade cylinders can provide.
