Introduction

A liquid oxygen system is designed to provide sup- plementary oxygen as prescribed by a physician. Your liquid oxygen system includes a HELiOS portable unit and a stationary reservoir. The reser- voir is the larger container that is used to fill your HELiOS portable. This user manual contains only the instructions for using the HELiOS portable. Re- fer to the user manual supplied with your reservoir unit for information on its operation.
HELiOS portable liquid oxygen units are designed to be an ambulatory source of oxygen for an extended period of time. They are filled with liquid oxygen from a reservoir unit with a compatible fill connector. HELiOS portables are available in two different sizes.
The H300 Plus is primarily a conserving device and holds 0.38 Liters of liquid oxygen. It provides demand (pulse) flow settings 1-4, and limited low dose continuous flow settings at 0.75 LPM and below only. The H850 Marathon can be used as a conserving or continuous flow device and holds 0.84 liters of liquid oxygen. It provides continuous flow from 1-6 LPM and demand flow on settings of 1-4.

Fill Connector Compatibility

The H300 and H850 can be filled from any CAIRE top-fill (TF) reservoir that has a CAIRE-style male fill connector. The compatible male and female connections for the HELiOS portable units are shown here.

CAIRE male (reservoir) and female (H300/H850) fill connectors

Dual Lumen Cannula

In order to breathe from your H300 or H850, you must do so through a dual lumen nasal cannula. This type of cannula has two connections to the portable unit. One connection is used to detect when you inhale, and the other connection is used to deliver oxygen to your nose.
A single lumen cannula cannot be used on the H300/H850. Your breath through the cannula pro- vides the force necessary to open the flow control valve and deliver oxygen. You must use a dual lumen cannula and inhale through your nose on ALL flow settings to ensure that oxygen is properly delivered.

Note: Oxygen will only be delivered through the top cannula barb.

Dual lumen nasal cannula operation: Oxygen is delivered through
top port. Breath is detected through bottom port.

Note: To Equipment Provider: The following oxygen administration accessories are recommended for use with the HELiOS:

Nasal Cannula: CAIRE Part Number 6-778057-00
Firebreak: CAIRE Part Number 21126636 A firebreak is recommended for use with any cannula.
CAIRE offers a firebreak intended to be used in conjunction with the oxygen The firebreak is a thermal fuse to stop the flow of gas in the event that the downstream cannula or oxygen tub- ing is ignited and burns to the firebreak. It is placed in-line with the nasal cannula or oxygen tubing between the patient and the oxygen outlet of the HELiOS. For proper use of the firebreak, always refer to the manufacturer’s instructions (included with each firebreak kit).
For any additional recommended accessories, please see the Accessories Catalog (PN ML- LOX0010) available on caireinc.com.

Operating Instructions – Filling

Clean the fill connectors on the H300/H850 and the reservoir with a clean, dry, lint-free cloth.
WARNING: THE FILL CONNECTORS MUST BE CLEAN AND DRY WITH A LINT-FREE CLOTH ON BOTH THE STATIONARY AND PORTABLE UNITS TO PREVENT FREEZING AND POSSIBLE EQUIPMENT FAILURE. WARNING: DO NOT DEPRESS OR DISTURB THE POPPET ON THE FILL CONNECTOR WHEN DRYING IT. THIS CAN CAUSE LEAKAGE OF LIQUID OXYGEN.
Turn the flow control knob on the H300/H850 to the off (“0”) position.
Hold the H300/H850 with both hands and position its fill connector over the reservoir fill connector.
Lower the portable onto the reservoir until you feel the connectors engage.
Place one hand on top of the H300/H850 and apply a constant downward force.
Open the vent valve by pulling downward on the vent valve lever to begin the filling process. You will hear a hissing sound that is perfectly normal.
You may see vapor around the fill connection. This is normal due to the great difference in temperature between the liquid oxygen and the warm surrounding air.
Maintain a downward force on the H300/H850 with one hand during the entire filling process and keep the vent valve lever open with the other hand.
Approximately 20-30 seconds into the fill, close and re-open the vent valve one or more times. This will prevent the valve from freezing open.
The unit is full when the hissing sound changes in tone and a dense white vapor is seen coming from under the shroud of the reservoir. When this is observed, close the vent valve by raising
the vent valve lever. This will terminate the fill.
Hold the handle on the H300/H850 and push the release button on the reservoir until the portable separates (release button varies by model
Check the contents indicator to verify that the unit is full.

WARNING: DO NOT LEAVE UNIT UNATTENDED WHILE FILLING.
WARNING: DO NOT OPERATE THE H300/H850 WHILE ATTACHED TO THE RESERVOIR UNIT.

WARNING: SHOULD LEAKAGE BE EXCESSIVE TO THE POINT THAT A STREAM OF LIQUID IS PRES- ENT, LEAVE THE AREA AND CALL YOUR HEALTH CARE PROVIDER IMMEDIATELY.
WARNING: IF LARGE AMOUNTS OF VAPOR ARE ISSUING FROM THE UNITS DURING FILLING, STOP FILLING, LEAVE THE ROOM AND CALL YOUR HEALTH CARE PROVIDER.
WARNING: IF PROLONGED HISSING IS HEARD, STOP USE AND CONTACT YOUR HEALTH CARE PROVIDER IMMEDIATELY
WARNING: IF THE H300/H850 DOES NOT SEPA- RATE EASILY, DO NOT USE FORCE. THE UNITS MAY BE FROZEN TOGETHER. LEAVE THE UNITS CONNECTED AND WAIT UNTIL THEY WARM UP

– THEN THEY WILL SEPARATE EASILY. DO NOT TOUCH ANY FROSTED PARTS.

Caution: Should there be any liquid leakage from the portable after separating the units, , set the H300/H850 aside, ensuring it remains vertical, leave the room, and call your health care provider immediately.

Caution: Should there be any liquid leakage from the reservoir after separating the units, open windows in the room, leave the room im- mediately, and call your health care provider.
Caution: Check the liquid level only after the vent valve is closed.
Caution: If the H300/H850 is being refilled immediately after a period of use, fill it, and then wait approximately one (1) hour after fill- ing with the flow control knob set to off (“0”) for the pressure to stabilize. Then operate as normal.

NOTE: If the HELiOS portable is warm or has not been filled recently, it may take approximately 90 seconds to fill an H300 or approximately four (4) minutes to fill an H850.

Operating Instructions – Breathing From the Portable

Attach both ends of a dual-lumen cannula to the connection ports on the H300/H850. Either end of the cannula may be attached to either connection port on the portable.
Position the nasal cannula properly on your face so that you will be able to breathe comfortably.
Turn the flow control knob until the setting prescribed by your physician is fully visible in the window on top of the H300/H850.
Breathe normally, inhaling through your nose. Oxygen delivery will not begin until you inhale through the nasal cannula.
NOTE: If the unit is on a demand (pulse) setting, you will notice a small pulse at the beginning of each inhalation. Oxygen is delivered during this pulse, and continues as long as you inhale. Oxygen flow stops when you stop inhaling.
NOTE: If the unit is in continuous flow, the H300/ H850 will deliver a steady stream of oxygen. You must continue to breathe through the nasal cannula normally to continue receiving continuous flow.
Note: Due to the possibility of excessive moisture/ ice build up it is recommended that the H300/ H850 remain idle for 1 hour after use to decrease moisture buildup
You should be receiving oxygen flow now. Verify that you feel oxygen delivery.
Use the duration charts available at www.CAIREmedical.com as a guideline to determine the length of time the H300/H850 will operate.
Under certain conditions (especially continuous use when the portable is not moved) the H300/ H850 may develop frost on the case. You may reduce this frost by wiping any accumulated frost off the case.
To stop the flow of oxygen, turn the flow control knob to the off (0) position.

NOTE: Do not open the vent valve during normal operation.
NOTE: The H300/H850 may be operated in an upright position, flat on its back, or any position in between these two locations.

Operating Instructions – Level Verification

Lift the H300/H850 by the contents indicator strap.
Push the bottom backside of the unit forward until it is straight up and down.
Observe the green bar in the contents indicator window. The window is completely filled with the green bar when the unit is full of liquid oxygen.

The following information is intended to help you troubleshoot and solve simple operational problems that you may experience when using your HELiOS Portable.

The Portable makes a hissing sound.
• Hissing can occur to maintain the correct operating pressure within the Portable. It is most likely to hiss after filling or when the position of the Portable is changed. Hissing can last for approximately 10 minutes after filling. Additionally, it can occur when the flow control valve is at a low setting.
The Portable does not pulse after filling.
• If during the filling process, the Portable is disengaged with the vent valve lever down, pressure may be reduced within the Portable causing a delay in the conserving device function. It may require as much as 60 minutes to restore adequate pressure for accurate oxygen flow. Additionally, improper filling or lower than normal operating pressure in the Reservoir will contribute to the unit not pulsing.
3. The Portable stops pulsing during use.
Ensure that both connections of the dual lumen cannula are firmly attached to the Oxygen Outlet and Sensor connectors.
• Change the cannula if water droplets are present from humidified exhaled gas. Replacing the cannula with a dry one enhances the ability of the Portable to pulse.
• Ensure that the cannula is not kinked.
• Ensure that the cannula tips remain in your nostrils and do not slide to one side.
• Ensure that there is oxygen in the Portable.
• With the cannula on, close your mouth and breathe only through your nose to verify that the Portable has stopped pulsing.
The Portable does not fill.
• Verify that there is oxygen in the Reservoir.
• Ensure that the Portable and Reservoir fill connectors are fully engaged throughout the filling process.
The Portable vent valve does not close properly at the end of the filling process.
• If the vent valve fails to close and the hissing sound and oxygen vapor cloud continue, carefully remove the Portable by depressingthe release button on the Reservoir. Ventingfrom the bottom of the Portable will stop in
a few minutes. Allow the unit to warm until you can close the vent valve. The Portable may require as much as 60 minutes to restore adequate pressure for accurate oxygen flow.
If needed, use an alternate source of oxygen such as a flow control valve attached to the Reservoir.
The Portable does not disengage easily from the Reservoir after filling.
• The Portable and Reservoir fill connectors may have become frozen. DO NOT USE FORCE. Allow a few minutes for the frozen parts to warm, then disengage the Portable
when the ice has melted. To prevent the units from freezing together, always wipe the male fill connector on the Reservoir and the female fill connector on the Portable with a clean, dry cloth before filling.
