The LSP Elder Demand/Resuscitator Valve is designed to provide 100% oxygen to a breathing or non-breathing patient in an emergency situation. The valve is designed for use with a mask, endotracheal tube, tracheotomy tube or esophageal airway.

The Elder Demand/Resuscitator Valve complies with AHA guidelines recommending that 100% oxygen be given to victims of a heart attack and/or smoke inhalation. The valve can be used in conjunction with a portable oxygen cylinder equipped with a pressure regulator or with a central oxygen source. The valve operates on a regulated oxygen supply of 40-60 psig (275 to 413 kPa) and reduces this pressure to a physiologically acceptable level with a pressure limit of 60±5 cm H2O. This prevents excessive buildup of intrapulmonary pressures and over-inflation of the lungs.

The slight negative pressure created by a spontaneously breathing patient’s inspiratory effort triggers the valve from a non-flow state to a flowing state. The greater the inspiratory effort, the higher the flow. When the inspiratory effort stops, the flow stops. The non-breathing valve permits it to be used as a resuscitator in combination with a manually operated button located on top of the valve.

The Elder Demand/Resuscitator Valve provides an accurate constant flow rate of 40 lpm to help prevent gastric inflation, as recommended by the AHA.


  • 40 lpm Flow Rate (restricted flow): As required in demand mode, 0-40 lpm at 50 psig (344 kPa); in resuscitation mode, a constant flow of 40 lpm at 50 psig (344 kPa)
  • 160 lpm Flow Rate: As required in demand mode, 0-160 lpm at 40 psig (275 kPa); in resuscitation mode, a constant flow of 160 lpm at 40 psig (275 kPa)
  • Delivery Pressure: 60±5 cm H2O unless otherwise indicated on the demand valve
  • Crack Pressure: -1.0 in. H2O (-2.54 cm H2O)
  • Supply Pressure: 50 psig (344 kPa)
  • Operating Temperature: -30° F to 125° F (-34.4 C to 51.7 C)
  • Storage Temperature: -40° F to 160° F (-40 C to 71.1 C)
  • Inlet Fitting: standard 1/8" NPT female
  • Filter: 2 micron sintered stainless steel
  • Outlet: 22 mm outside diameter x 15 mm inside diameter
  • Materials: housings and plastic parts - Valox, polyester; polysulfone; moving and adjusting parts - stainless steel; fasteners - steel, brass and aluminum, all plated for corrosion resistance; rubber parts (except oxygen hose) - silicone


  • Maximum cylinder use – flow rate of 40 lpm is maintained at cylinder pressures between 200-2200 psig (1378 to 15168 kPa), allowing for complete use of cylinder contents
  • Easy to clean and service – valve obstruction may be removed during resuscitation with minimal interruption, and may also be chemically disinfected
  • Compact, lightweight and durable – will withstand corrosive materials and harsh weather conditions
