Introduction

ImPulse™ Elite is an electronic oxygen conserving device (OCD) that provides convenience and mobility to patients with therapeutic oxygen needs. Designed and manufactured by AirSep Corporation, ImPulse Elite uses portable cylinders to provide patients with oxygen delivery at their prescribed dosages.

With this device, actual oxygen delivery to the patient occurs at or near the beginning of the breathing cycle when the patient starts to inhale.

Because ImPulse Elite does not deliver oxygen during exhalation, which accounts for approximately two-thirds of the breathing cycle, it wastes little or no oxygen. This differs greatly from conventional oxygen systems that deliver oxygen continuously. In addition, many patients are more comfortable with

oxygen conserving devices than continuous ow

systems because they have fewer problems with nasal

dehydration that can result from constant ow into the

nostrils.

Maximizing Delivery with ImPulse Elite

ImPulse Elite’s advanced electronics enable it to respond effectively to a patient’s respiratory cycle. ImPulse Elite senses the start of inhalation. Because only a small amount of oxygen is actually required to oxygenate the blood effectively, ImPulse Elite delivers

the precise amount when it is most benecial — at the

beginning of inhalation.

ImPulse Elite quickly delivers a pulse of oxygen compatible with your breathing rate and automatically

adjusts with any change in your breathing cycle —

depending on your prescribed oxygen requirement.

This method of oxygen delivery has been clinically

tested and determined to meet oxygen needs satised by comparable ow settings on continuous ow units

up to 6 lpm.

Initial Setup

As part of your initial set up with ImPulse Elite, your clinician may choose to assess your saturation level through pulse oximetry. This helps to ensure proper titration while using the oxygen conserving device.

Safety

ImPulse Elite meets applicable safety and environmental regulations. This assurance means

you can fully enjoy all the benets of this device.

However, with all electronic devices and applications that require oxygen, normal care and precautions must be followed.

Before you attempt to use this oxygen conserving device and a portable oxygen cylinder, read all warning and caution notes in this section of the manual. Contact your Equipment Provider should you have further questions.

Testing and Replacing Battery

ImPulse Elite requires just one 1.5 volt “D” size alkaline battery (Energizer recommended) for full operation. Battery life is dependent upon the predetermined unit settings, your breathing rate, and the length of daily ambulation time. Most patients experience 10–18 months of battery life. AirSep strongly recommends that you maintain a spare battery in your carrying case for replacement in this unit as necessary.

To install or replace the battery, follow the steps below:

1. Make sure the ON/OFF power switch is set to the OFF position. (It is not necessary to disconnect the cannula or remove the ImPulse

Elite from the cylinder, although you may nd

it easier to replace the battery within the battery

compartment door if the unit is rst removed

from the cylinder.)

2. If the unit is not connected to the cylinder, simply hold the unit with one hand while you press in and lift up on the battery compartment latch with your other hand. (Figure 7).

Figure 7

3. Insert a fully charged battery into the inside door of the battery compartment. Make sure the battery is properly positioned to match the correct positive and negative polarity markings (Figure 9).

“+”Positive Polarity

“-” Negative Polarity

Figure 9

To test the battery to ensure that there is proper power available to operate the unit:

1. Make sure there is a battery in the unit’s battery compartment and it is properly positioned to match the correct positive and negative polarity markings.

2. Make sure the ON/OFF power switch is set to the ON position.

3. Press and hold down rmly the center of the BAT. TEST button with your nger. (Figure

10.) (You can test the battery regardless of whether or not a cannula is connected to the oxygen outlet.)

If the unit is connected to the cylinder, steady the unit by grasping the neck of the cylinder just below the unit with one hand while you press in and lift up on the battery compartment latch with your other hand (Figure 8).

ImPulse Elite User Manual — 7

Turning On the Unit for Proper Oxygen Usage

Note: Do not use a mask with the ImPulse Elite unit. A mask may not conform to the face properly enough for the unit to fully sense inhalation.

Note: Do not use pediatric or low ﬂow cannulas with the ImPulse Elite unit as their smaller tubing diameters negatively affect delivery volumes.

6. Turn the cylinder valve slowly one full turn

counter-clockwise to begin oxygen ow.

7. Make sure the cylinder contents gauge on the ImPulse Elite unit registers within the green shaded/green zoned areas.

This indicates an adequate oxygen supply in the cylinder. (If the cylinder contents gauge indicates the red REFILL zone, the cylinder needs to be replaced.)

Note: Use ImPulse Elite during sleep only under the recommendation of a qualiﬁed clinician.

1. Check the energy level of the battery each time you use the unit.

Refer to “Testing and Replacing Battery” for step-by-step instructions.

2. Check the oxygen cylinder setup and the cylinder contents gauge.

If you need to change cylinders, which includes removal and reconnection of the ImPulse Elite unit, refer to Oxygen Cylinder Connection for step-by-step instructions.

3. Make sure the PULSE FLOW / CONTINUOUS FLOW switch is moved completely right (for

pulse ow setting).

4. Set the ON/OFF switch to the ON position.

All three lights illuminate for less than 1 second. The ImPulse Elite unit automatically calibrates and reaches sensitivity within approximately 15 seconds. Then the green light shuts off, and the unit emits a short burst of oxygen. This indicates ImPulse Elite is ready for use.

5. Connect your cannula to the oxygen outlet. (You may use up to a 25 ft [7.5 m] cannula, if desired.) (Figure 11.)

Listen for gas leaks coming from the ImPulse Elite and oxygen cylinder. If you hear a leak, turn off the cylinder valve and refer to the Troubleshooting Guide on page 11.

8. Position the nasal cannula with the prongs inserted into your nostrils.

9. Set the ow selector between 1 and 6 depending

on your prescribed dosage (Figure 12).

Figure 12

Turning Off the Unit

1. Turn the oxygen cylinder valve fully clockwise

to stop oxygen ow.

2. Set the ON/OFF power switch on the ImPulse Elite unit to the OFF position.

Note: If you do not set the unit’s ON/OFF power switch to OFF when the unit is not in use, the alarm sounds until the battery fully discharges.

discharged battery in unit.

Switching to Continuous Flow

If your unit is equipped with a continuous ow switch:

For very short time periods, this PULSE FLOW/ CONTINUOUS FLOW switch at the base of the unit can be moved completely left for CONTINUOUS FLOW to force the oxygen conserving unit to perform

as a continuous ow unit (Figure 13).

Figure 13

A typical use for the CONTINUOUS FLOW setting occurs when the battery can no longer provide power.

This setting provides 2 lpm of continuous ow

oxygen.

Before setting ImPulse Elite to CONTINUOUS FLOW, make sure you set the ON/OFF power switch to the OFF position to preserve battery life as this is a manual override and no audible or visual alarm indicators are available in this “temporary” setting.

CAUTION: The continuous ﬂow setting uses substantially more oxygen than the normally used pulse ﬂow setting. Make sure

the cylinder contents gauge is observed often when operating the unit as a continuous ﬂow device.

Removing/Replacing the Cylinder

To easily remove the ImPulse Elite unit from a cylinder:

1. Close the oxygen cylinder valve by rotating the valve completely clockwise.

2. Press the BAT. TEST button OR temporarily set the PULSE FLOW/CONTINUOUS FLOW switch to the CONTINUOUS FLOW setting until no oxygen can be heard venting from the unit.

3. Turn the unit’s securing knob counterclockwise to lift the unit off the cylinder.

ImPulse Elite as a Portable Unit

The ImPulse Elite unit and its accessories are light weight and portable. This means that ImPulse Elite can go virtually anywhere you go.

CAUTION: Do not expose the device to, or submerge it in, water.

CAUTION: Do not expose the device to extreme temperatures.

The universal-style carrying case, as shown in Figure 14, can be used with the unit. During use, ImPulse Elite should remain in your carrying case. This ensures added protection for the unit and allows discreet use. Simply check periodically to ensure that your cannula connection is secure and that the cylinder shutoff valve remains in the open position (one full turn counterclockwise) to enable oxygen

ow.

Figure 14

Proper Care & Maintenance

Each time you use the ImPulse Elite, check the following as described on page 8; 1.) battery level,

2.) cylinder contents, 3.) pulse ow / continuous ow setting, 4.) the green pulse light shuts off in

approximately 15 seconds after turning on switch, 5.) listen for gas leaks coming from the ImPulse Elite and oxygen cylinder. For any failure, refer to the Troubleshooting Guide on page 11.

Keep the ImPulse Elite clean and free from moisture, dust, and extreme temperatures. To help prevent possible damage to the unit, keep ImPulse Elite in its carrying case.

Clean the unit periodically by wiping with a lint-free cloth. Pay special attention to the oxygen outlet for the cannula connection to make sure it remains free of dust, water, etc. Do not expose or submerge the ImPulse Elite device in water.

We recommend using a one-part bleach to 99 parts water solution or using Fantastik® spray cleaner as a safe cleaner for the ImPulse Elite’s outer housing.

A list of undesirable chemical cleaning agents includes, but is not limited to the following, according to the plastic manufacturer: alcohol and alcohol-based products (isopropyl alcohol), concentrated chlorinebased products (Ethylene Chloride), and oil-based products (Pine-Sol, Lestoil). These are NOT to be used to clean the plastic housing on the ImPulse Elite OCD. These chemicals and the cleaners that contain them will crystallize the plastic and break down the plastic’s molecular properties.

Replace the disposable cannula periodically following normal usage. Additional supplies are available from your Equipment Provider or AirSep.

10 — MN092-1 D

Return empty oxygen cylinders to your supplier for replacement. Remove the unit from the empty cylinder before returning the cylinder to your supplier.
