Reservoir virtually eliminates oxygen evaporative losses both in standby mode and when supplying gaseous oxygen to a patient The Reservoir is available in two models that are nearly identical with the exception of the liquid oxygen storage capacity The H 46 holds 110 pounds of liquid oxygen while the H 36 holds 85 pounds of liquid oxygen Figure 1 HELiOS H 46 and H 36 Reservoir Units The Reservoir uses the popular Puritan Bennett top fill connector and is compatible with Puritan Bennett Companion filling equipment vent wrench transfer hose assembly source tank The Reservoir requires a minimum 24 psig 166 kPa saturated liquid oxygen to operate and may be filled using standard or fast fill techniques Section 6 0 A standard integral pressure indicator on the unit helps the filling technician maintain proper liquid oxygen saturation pressure during the fill An electronic contents indicator uses reliable differential pressure based level sensing technology to provide accurate and easy to read liquid oxygen contents indication The 9 volt battery powered contents indicator incorpo rates high visibility LEDs for indicating liquid oxygen contents LEDs also warn of low battery and low contents conditions HELiOS Reservoir Reference Guide 1 The Reservoir provides 22 psig 152 kPa gaseous oxygen at up to 10 L min continuous flow through a Diameter Index Safety System DISS connection Oxygen outlet pressure is regulated at 22 psig
