Appendix B: Using Pressurized
and/or Anesthetic Gases
The VentElite was designed to operate utilizing gas sources of atmospheric pressure. When
pressurized, constant flow devices are used with the VentElite (such as regulators, flowmeters,
and house gas supplies) measures must be taken to ensure no damage is done to the unit.
We recommend the use of our connection kit when using a high pressure gas source with the
VentElite, or any of our ventilators. The connection kit prevents the buildup of pressure from
constant flow devices such as those referenced above. Below is a schematic of the connection
kit. The appropriately sized connection kit for the VentElite is the 73-4872 connection kit.
