The 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, or tracheotomy tube.
The Demand Resuscitation 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 Demand/Resuscitator Valve provides an accurate constant flow rate of 40 lpm to help prevent gastric inflation, as recommended by the AHA. It is also available with a minimum flow rate setting of 160 lpm.
- Maximum cylinder use … flow rate of 40 lpm is maintained at cylinder pressures between 500-2200 psig (3447 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; valve may also be chemically disinfected
- Compact, lightweight and durable … will withstand corrosive materials and harsh weather conditions
