– L471 Bag Refill Valve (No Hose or Fittings)
The LSP Bag Valve L471 Refill Valve makes it possible for bag / mask resuscitators to easily and quickly deliver 100% oxygen to the patient on a consistent basis.
The LSP Bag Refill Valve is a demand valve with adapter allowing it to connect into the filling port of a bag valve mask resuscitator for the purpose of providing a high-flow (up to 200 litres/min) source of concentrated oxygen.
The significant difference between the LSP Bag Refill Valve and currently used bag / mask resuscitator reservoir systems is that the bag refill valve will conserve gas which conventional reservoir systems tend to waste. It will approximately DOUBLE the working duration of any oxygen cylinder when compared to using a BVM reservoir system receiving oxygen continuously at 15 litres per minute.
In addition the first vital ventilations of the patient will be very close to 100% oxygen as opposed to a reservoir system which typically slowly builds towards a concentration of between 60 to 90% oxygen. An excellent clinical advantage when those first few seconds to oxygenate the patient are vital.
In early 2004 Laerdal changed their BVM design. A new rear inlet valve assembly is now being utilised. This has caused many problems with bag refill valves and can no longer be used on the new Laerdal BVM.
Laerdal has recognised this and has made available the earlier style of rear inlet valve which must be used in place of the later version.
