INTRODUCTION The CYPRESS OXYPneumatic oxygen conserver includes a combination of a lowpressure regulator and an oxygen conserver, designed for use with a cylinder as an ambulatory oxygen system. It is capable of delivering a precise amount of supplemental oxygen at the optimal point in the breathing cycle. The CYPRESS conserver greatly increases the efficiency in the delivery of oxygen, maximizing the beneficial effects and eliminating unnecessary oxygen waste. When we breathe, approximately one-third of the time is spent inhaling and two-thirds exhaling. As a result, oxygen delivered by continuous flow is wasted during exhalation. By eliminating oxygen flow during exhalation, a two-thirds savings is possible. Additionally, the oxygen available during the very first part of inhalation contributes most to meeting oxygen needs. The CYPRESS conserver takes advantage of these facts to provide maximum efficiency in the delivery of oxygen. This device is designed to be an integral component of a lightweight, long-lasting ambulatory oxygen system.

ASSEMBLY AND USE • Make certain that your hands are free of oil, grease, and other contaminants. • Inspect the unit to ensure that it has the appropriate viton (or equivalent) gasket, in good working condition, attached to the inlet nozzle. • Secure the cylinder in an upright position. • Inspect the valve of the cylinder and the CYPRESS conserver to ensure they are free of contaminants. If any indication of damage or contamination is detected, DO NOT use the equipment and contact your Home Care Provider. WARNING: Use ONLY a manufacturer specified gasket. An incorrect gasket may not be oxygen compatible or may cause an oxygen leak, creating an increased fire risk. NON-PORTABLE USE: The CYPRESS conserver is designed to extend the life of portable oxygen supplies when away from the primary source. While the CYPRESS conserver may be used with stationary oxygen sources, the unit should be used only while awake and reasonably attentive. The CYPRESS conserver is not intended for use while asleep because, in the unlikely event of operational malfunction or dislodging of the cannula, the user could be unaware and not make the necessary corrections.

ASSEMBLY AND USE INSTALLING THE SYSTEM (CGA 870 Models): STEP 1: Loosen the cylinder adjustment knob. STEP 2: Lower the CYPRESS conserver over any post valve cylinder with the alignment pins toward the holes on the cylinder neck [see Fig. D]. STEP 3: Line the two pins and gasket with the corresponding holes on the cylinder post valve.

* NOTE: Cylinder adjustment knob

ASSEMBLY AND USE OPERATING INSTRUCTIONS: STEP 1: Make sure that the CYPRESS conserver is set to the “OFF” position before opening the cylinder valve. STEP 2: To reduce the risk of rapid oxygen recompression and fire, open the cylinder valve slowly and completely so the pressure gauge moves slowly as it indicates the cylinder pressure. STEP 3: Listen for leaks. If a leak is present, close the cylinder valve, check the CGA seal, and reinstall. If the leak persists, DO NOT USE THE FIGURE F EQUIPMENT. Contact your Home Care Provider for repair. View of the CYPRESS STEP 4: Check the CYPRESS oxygen pressure gauge to verify the cylinder selector switch pressure. STEP 5: Select the setting on the CYPRESS conserver to the appropriate delivery setting [See Fig. F]. STEP 6: Ensure that the vent hole [see Figs. A & B, pg. 6] on the side of the unit is not obstructed. STEP 7: As with any nasal cannula, place the nasal cannula into position with the prongs in the nostrils and begin breathing. The CYPRESS conserver will now start to deliver oxygen. The amount of oxygen delivered per pulse is determined by the setting. A sound may be heard each time the unit delivers a pulse of oxygen. Adequate oxygenization will be achieved because of the precise time in the breathing cycle in which the pulse of oxygen is delivered.

*

NOTE: To help prevent possible damage to the unit and to maintain its cleanliness, keep the CYPRESS conserver in a carrying bag designed for use with your CYPRESS model.

STEP 8: When finished using the system, close the oxygen supply cylinder valve and continue breathing through the nasal cannula until no further oxygen is detected. STEP 9: Remove the nasal cannula and turn the selector switch to the "O" (off) position. STEP 10: When not in use, store in a clean, dry location.

OXYGEN CYLINDER DURATION Because the total delivery of oxygen via the CYPRESS conserver is related to the breathing rates, it is user adaptive in that the total oxygen delivered per minute will automatically adjust with user need, as expressed by increased or decreased breathing rates. For example, at all settings, twice as much oxygen per minute will be delivered if one breathes twenty (20) times per minute as compared with ten (10) times per minute. Tables 1 and 2 below can be used as a guide. TABLE 1 CYPRESS Models 511, 511WG, 523
