INTRODUCTION TO YOUR HELiOS OXYGEN SYSTEM Your HELiOS Oxygen System is designed to store and deliver oxygen at a prescribed rate. The system consists of two units: the Portable and the Reservoir. The Portable can be supplied with oxygen for you to breathe in two ways. First, you may fill the Portable with liquid oxygen so you can be free to move about your home or leave your home for extended periods. Second, you can connect the Portable to the Reservoir. The Portable may be used with either a standard HELiOS Reservoir or a HELiOS Universal Reservoir. The HELiOS Universal Reservoir can also be used to fill Puritan Bennett Companion® portables. Refer to the Companion portable operating instructions for procedures to properly fill the Companion portable. The HELiOS System was designed to maximize your freedom of movement. You can fill the Portable with liquid oxygen every day to use as far from the Reservoir as you desire. When you are in your home and not moving about, such as in the evening or while you are sleeping, you may connect the Portable to the Reservoir with an oxygen supply line. When the Portable is connected to the Reservoir in this manner, the oxygen you breathe is supplied by the Reservoir unit. Your oxygen supplier (e.g. home care provider) must refill your Reservoir unit periodically depending upon your rate of oxygen use.

HOW TO USE YOUR HELiOS OXYGEN SYSTEM Filling the Portable Unit Fill the HELiOS Portable unit from the Reservoir as follows:

WARNING •

•

Using a dry cloth that is clean, wipe the fill connector dry on both the Reservoir and Portable units before filling to prevent freezing and possible equipment failure. Extreme cold hazard. Do not press or disturb the plastic poppet in the center of the fill connector on the Reservoir. This will cause a release of liquid oxygen from the fill connector.

1.

Check the contents indicator on the Reservoir by pressing the blue button to ensure there is enough liquid oxygen for filling purposes. If the yellow light comes on, you may proceed with filling the Portable, but you should inform your oxygen supply company.

2.

Using a dry cloth that is clean, wipe the male fill connector on the Reservoir and female fill connector on the Portable.

3.

Position the HELiOS Portable over the recessed area in the top of the Reservoir. (Figure 1).

701641 Rev. E

4.

Carefully lower the Portable into place, ensuring that the fill connectors are properly aligned.

5.

Place one or both hands on top of the Portable and press straight down directly over the fill connector , being careful not to depress the release button on the Reservoir when engaging (Figure 2). This will lower the Portable unit approximately 3/8 inch (10 mm). Continue to apply downward force to ensure the fill connectors remain engaged.

6.

While holding the Portable unit in the fill position, pull down and hold the vent valve lever in the open position (90° from the normal “off” position) (Figure 2). A hissing noise should be noticeable. During filling, maintain a slight downward force on the unit with one hand to keep the unit steady and maintain proper filling position.

NOTE: Fill time is usually between 25 and 60 seconds when the Portable is empty. The amount of time to fill the unit depends on the amount of oxygen remaining in the Portable.

WARNING Do not leave the HELiOS Portable unattended during the filling operation.

7.

When you notice a change in the sound of venting gas followed by a dense, white vapor forming around the Reservoir cover, close the Portable vent valve by returning the vent lever to the upright position.

CAUTION If the vent valve fails to close and the hissing continues, remove the Portable unit by depressing the Portable release button on the Reservoir unit. The Portable will stop venting 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. An alternate source of oxygen, such as a flow control valve attached to the Reservoir, can be used if needed. NOTE: For shorter planned use times, you can partially fill the Portable by closing the vent valve sooner than normal. The Portable will then be lighter to carry.

8.

Disengage the Portable from the Reservoir unit by holding the carrying handle and depressing the release button (Figure 3). Always hold the Portable unit with at least one hand when attempting to disengage it.

NOTE: If the units will not disengage easily, they may have become frozen. DO NOT USE FORCE. Simply allow a few minutes for the frozen parts to warm, then disengage the Portable when the ice has melted. 701641 Rev. E

11

WARNING • If a minor liquid oxygen leak from the Reservoir fill connector occurs when you disengage the Portable, re-engage and disengage the unit to help dislodge any ice or other obstruction. If the liquid oxygen leak persists, notify your oxygen supplier. • If a major liquid oxygen leak from the Reservoir fill connector occurs when you disengage the Portable unit (that is, a steady stream of liquid oxygen), stay away from the unit and immediately notify your oxygen supplier. NOTE: Immediately after filling, you may hear a slight hiss from the Portable. This is normal and will stop after a few minutes.

9.

Check the oxygen contents indicator to make sure the Portable unit is filled to the desired level. The amount of liquid oxygen contained in the Portable is measured by an internal scale that is built into the unit. To operate the contents indicator: (1) lift the HELiOS Portable unit by the contents indicator strap, (2) push the bottom backside of the unit so that it is straight up and down and (3) observe the green bar that displays the liquid oxygen contents level inside the clear window (Figure 4).

NOTE: Do not try to overfill the Portable. Once you hear the change in the sound of venting gas and see the cloud of white vapor, the unit is full. Continuing the fill process will not put any more oxygen in the Portable. Overfilling may cause drops of liquid oxygen to spray from the bottom of the Portable.

NOTE: After each fill, do not try to refill the Portable again for at least 30 minutes. This will prevent the possibility of the unit wasting oxygen and prevent the vent valve from potentially freezing.

NOTE: The number of times that you have to fill up or “top off” your HELiOS Portable depends on which of the 11 settings is prescribed by your doctor and the frequency of your breath rate. On average, a setting of 2 lasts about 8 to 10 hours. However, the actual time may vary depending on your particular circumstances.

NOTE: You may also fill the HELiOS Portable from Puritan-Bennett Companion C21, C31, C41 Stationary or Companion Low Loss C31LL units.

Breathing From the Portable Unit In order to breathe from your HELiOS Portable, you must do so through a duallumen nasal cannula. The nasal cannula has two connections at the Portable. One connection is used to sense when you inhale, the other connection is used to supply oxygen into your nose as you inhale. Connect a dual-lumen cannula to your Portable as follows: 1.

Attach both ends of dual-lumen cannula to the Portable as shown below. Either end of the dual-lumen cannula may be attached to either connector on the Portable (Figure 5).

2.

Turn the flow control knob on the top of the Portable clockwise to the setting prescribed by your physician (Figure 6). The flow setting value should be clearly readable in the center of the window. The Portable unit will not deliver oxygen to you if the flow control knob is set between flow settings.

14

701641 Rev. E

When your Portable unit is set to 1 or above, oxygen will be delivered only while you inhale. You should notice a small pulse at the beginning of each breath. Oxygen is delivered during this pulse, and continues as long as you inhale. Oxygen flow stops when you stop inhaling. It is normal for the device to occasionally skip a breath or to pulse twice in one breath. When your portable unit is set below 1, oxygen is delivered continuously at the rate displayed on the flow control knob. For example, the .5 setting delivers continuous flow oxygen at .5 L/min. The table below shows approximate use times for your Portable unit after it has been completely filled. The table below was constructed using a breathing pattern that is typical for oxygen patients. Your use time may vary substantially from the use time listed below. You should learn through experience how long the Portable unit will last under your circumstances. The table below of approximate use times is correct even though in some cases it doesn't seem logical. For example, the .75 setting doesn't last as long as the 1 setting because the .75 setting is continuous flow and the 1 setting is demand flow. Also, the 1 setting doesn't last twice as long as the 2 setting because of unique properties of liquid oxygen. Approximate Use Time of a Full Portable Unit. YOUR USE TIME MAY VARY. Flow Control Knob Setting 0 .12 .25 .5 .75 1 1.5 2 2.5 3 3.5 4

CAUTION You must use a dual-lumen cannula of 7 foot length or shorter (see page 28) to insure proper oxygen delivery from the Portable unit. Make sure both connections of the dual-lumen cannula are firmly attached to the Portable Oxygen Outlet and Sensor connectors.

3.

With the tips of the cannula pointing downward and toward you, place the two tips into your nostrils. Run the tubing over your ears and then slide the sleeve up under your chin until the cannula feels comfortable (Figure 7). Then breathe normally.

NOTE: Make sure that the tips remain in your nostrils and do not slide to one side.

NOTE: Ocassionally water droplets caused by exhaled humidity may accumulate in the cannula. This may disrupt the operation of the oxygen conserving device. If this happens, replace the moist cannula with a dry one. Allow the moist cannula to dry before using it again.

NOTE: Currently, there are two dual lumen cannula designs available for use with the HELiOS. One cannula provides sensing and delivery of oxygen in each nostril. This is the best one to use when experiencing a blocked nasal passage. The other provides oxygen from one side and senses when to provide oxygen on the other. Also, the tips are slightly smaller and softer.

4.

The contents indicator will show approximately how much liquid oxygen remains in the unit. To ensure you have enough oxygen to meet your needs, check the indicator periodically. Hold the unit by the strap and push the bottom backside of the unit until it is straight up and down to read contents (Figure 8). When checking the contents, it is important to remove any carry accessories and to make sure your nasal cannula is not pulling on the Portable.

Positioning of Portable Unit During Use

WARNING Always keep the Portable in one of the following positions: upright, flat on its back or any position in between. Your HELiOS Portable was designed to operate in a variety of positions for your convenience. It is important to always keep the portable in one of these positions or oxygen may escape. This will shorten the time you can be away from home. Your HELiOS Portable is designed to work when sitting upright, when laying flat on it’s back or anywhere in between. The unit should not be placed on its front, on its edge or with the handle lower than bottom of the unit. Figure 9 shows typical situations and how the Portable should be positioned. Figure 10 shows unacceptable positions.
