Stroller/Sprint Introduction The liquid oxygen system includes a stationary unit and the Stroller/Sprint, which provides supplementary oxygen as prescribed by your physician. This POI contains the instructions for using the Stroller/Sprint. Refer to the POI supplied with the stationary unit for its operation. The Liberator is the larger container and is intended for stationary use. You may take oxygen directly from the Liberator. The unit is filled by your health care provider. The Stroller/Sprint provides an ambulatory source of oxygen for an extended period of time. They are filled from the Liberator.

Stroller/Sprint • Do not use or store your unit in an area where combustible materials such as oils, greases, aerosol sprays, lotions or solvents are present.

Warning Information Read this page carefully before using your unit.

• Keep your unit in a well-ventilated area.

• The unit contains liquid oxygen which is extremely cold; almost 300 degrees below zero Fahrenheit. Exposure to such a low temperature can cause severe frostbite.

• In the event of an accidental tip-over, immediately but cautiously return unit into an upright position. If any liquid oxygen is escaping, leave the area immediately and call your health care provider.

• Liquid and gaseous oxygen, though nonflammable, cause other materials to burn faster than normal. This hazard, along with the low temperature of liquid oxygen, warrants certain safety precautions.

• Do not touch the frosted parts of any unit. • Do not store or operate the Stroller/Sprint coupled to the stationary unit.

• Do not smoke while operating unit. • Do not use or store your unit within five feet of electrical appliances, especially stoves, heaters, toasters, and hair dryers.

Stroller/Sprint b. If your connector is Cryo2: Rotate Stroller/Sprint until you feel the connectors engage. Then, carefully and firmly, rotate the Stroller/Sprint counterclockwise ( ) while pressing downward.

To Fill the Top Fill Stroller/Sprint 1. Clean the fill connectors on both the stationary and the Stroller/Spirit with a clean, dry, lint-free cloth. Caution: The fill connectors must be dry, because moisture can cause your Stroller/Sprint and stationary unit to freeze together.

c. If the connector is a Penox, Life-Ox, or Lincare: Rotate Stroller/Sprint until you feel the connector engage. Then, carefully and firmly, rotate the Stroller/Sprint clockwise ( ) while pressing downward.

2. Make sure the flow control is in the off (0) position.

Note: Continued on step 6 (page 10).

3. Position the fill connector in the upright position over the stationary unit’s connector.

Step 3 4. a. If your connector is a push-on: Lower the Stroller/Sprint unit on to the stationary until you feel the connector engage. Step 4a 8

Stroller/Sprint To Fill the Side Fill Stroller/Sprint 1. Clean the fill connectors on both the stationary and the Stroller/Sprint with a clean, dry, lint-free cloth. Caution: The fill connectors must be dry, because moisture can cause your Stroller/Sprint and stationary unit to freeze together.

2. Make sure the flow control is in the off (0) position

Step 3

3. Make the Stroller/Sprint fill connector in the upright position to the stationary connector. 4. Rotate the Spirit counterclockwise ( ) until you feel the pin and slot engage. 5. Carefully and firmly rotate the Stroller/Sprint back to the upright position. Now the units are locked together. Note: Continued on step 6.

Step 4 9

Step 5

Stroller/Sprint Note: Closing the valve after a nearly continuous stream of liquid is discharging fills the Stroller/Sprint most completely, but wastes some liquid oxygen.

Note: For push-on style connector, hold the unit in place throughout the fill.

6. Open the vent valve to begin filling your Stroller/Sprint. You should hear some oxygen escaping; do not worry. The hissing sound you hear is perfectly normal. Note: Liquid level gauge readings are most accurate 30 seconds or more after the Stroller/Sprint is filled.

7. You may also see vapor around the connection. This is normal and is due to the great difference in temperature between the liquid oxygen and the warm air surrounding the units. 8. When the unit is full, close the vent valve. You can tell that the unit is full when the hissing sound changes in tone, and some liquid comes out of the vent line. Step 6 10

Stroller/Sprint Closing the valve at the first sign of liquid discharge does not fill the Stroller/Sprint as completely, but saves liquid oxygen.

Warning: Do not operate Stroller/Sprint while attached to the stationary unit. Warning: Should the leakage be excessive to the point that a stream of liquid is present, leave the area and call your health care provider immediately.

9. For the push-on style connectors, push the release button down until the units separate. For all other connectors rotate the unit until it separates from the stationary unit. Caution: Check liquid level gauge only after the vent valve is closed. Caution: If the Stroller/Sprint does not separate easily, do not use force. The units may be frozen together. Wait until the units warm up - then they’ll separate easily. Do not touch any frosted parts. Should there be any liquid leakage from the stationary unit or Stroller/Sprint after separation, reattach the Stroller/Sprint immediately. Again separate the units. If the problem persists, leave units coupled and call your health care provider.

11

Caution: If the Stroller/Sprint is being refilled immediately after a period of use, fill it, and then wait 10 minutes after filling with the FCV set at zero for the pressure to stabilize. Then operate as normal. Warning: Liquid or cold gaseous oxygen can frostbite the skin. Oxygen will result in increased fire hazard. Portable Release Button (push-on style only)

Stroller/Sprint Caution: Always turn the flow control knob off (0) when not in use.

Operating Instructions 1. Push the cannula breathing tube firmly on to the oxygen tube connector. 2. Adjust your cannula breathing tube to the proper position so that you will be able to breathe the oxygen comfortably. 3. Turn the flow control knob on top of the Stroller/Sprint clockwise until the prescribed flow rate (numeral) is visible in the knob “window” and a positive detent is felt. Warning: Out-of-specification oxygen flow will result if the flow control knob is set between flow rates.

4. You should be receiving oxygen now. To stop flow of oxygen, turn the flow control knob counterclockwise to the off (0) position.

*Cannula is not included 12

Stroller/Sprint 6a. To verify the level of liquid oxygen in the unit with the electronic liquid level gauge: • Depress the push button (liquid level switch) on top of the unit for two seconds minimum. Read across the top of the light bar to indicate contents level. Caution: The Stroller/Sprint is empty if only the last segment of the light bar is lit.

• If the Low Battery indicator lights up when the button is depressed, notify your health care provider.

GEN 3 Gauge

Note: The Stroller/Sprint will continue to supply oxygen even if the Low Battery Indicator lights up, as long as there is liquid oxygen in the unit.

GEN 4 Gauge 14

Stroller/Sprint 6b. To verify the level of liquid oxygen in unit with the mechanical liquid level gauge: • Support the unit, by the fabric strap, directly above the black contents indicator spring scale chamber. • Allow the unit to stabilize (i.e. not bounce up and down), then read the exposed colored scale for approximate liquid oxygen contents. Note: If the unit is empty, only the red colored band of the scale will be exposed. If this is the case, the unit must be filled prior to use.

7. Under certain environmental conditions, with continuous use, and especially with the portable not being moved, it may develop excessive frost around the vaporizer coil and on the case. You may reduce this frost by tapping the unit and/or wiping any accumulated frost off the case. 15

Stroller/Sprint 8. After the unit is empty and has warmed up to room temperature, remove any moisture from the condensation cup:

• Remove the pad from the cup and wring out any absorbed moisture. Allow the pad to dry completely before replacing it in the cup.

• Tilt the unit to one side. Grasp the knob at the center of the condensation cup (at the bottom of the unit) and pull straight out. This will release the cup.

Note: If heavily soiled, the pad can be machine washed (with bleach to disinfect).

• To replace the cup, center it over the round opening at the bottom of the unit and press the knob in one click to engage the cup and then a second click to lock the cup in place. Note: If the knob will not push in and engage the cup, hold the cup and pull the knob out until it clicks into the open position. Now replace the cup as previously described.
