Description

Manual Demand ValveThe 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 psi (275 to 413 kPa) and reduces this pressure to a physiologically acceptable level with a pressure limit

 

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 psi (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.

 Key Features

  • Maximum cylinder use … flow rate of 40 lpm is maintained at cylinder pressures between 500-2200 psi (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

Appearances Can Be Deceiving. Perfect Size
Color: Gold Triple Huggie
When I opened the package I was shocked at how tiny these appeared and my immediate thought was to return them without even trying them on. That would have been a mistake. I did order them because they were a smaller version of this look and I wanted them to look elegant and sophisticated rather than making a bigger statement. Well, that is exactly what I got. The gold color is very nice and once I decided to put one on, and got it through my chubby earlobe, it was absolutely perfect and the look I was going for. I have larger ear lobes and they still hang down enough for some movement rather than just cupping my earlobe like a true cuff. If you want this style with a more minimalist and elegant look, these are your earrings. I highly recommend them and be sure to try them on before you make a decision.

Tarnish quickly
Color: Gold Triple Huggie, Color: Gold Triple Huggie
Cute just wish they were better quality, they tarnished both on the part inside my ear and not as visibly but also on the outside, def not as shiny. I’ve had them for almost 2 months or so and the inside of my ear is turning green/ black. Like I need to use an alcohol wipe and qtip to clean the ear hole. Ive worn them almost always but I don’t wear them when I wash my hair. I wear them during my only body showers and also have in gym so maybe steam or sweat has added to moisture that tarnished it but I’m disappointed at how quick they tarnished.
