eFlow is an electronic nebulizer that makes a breathing treatment go faster. This is due to
“touchspray” technology that vibrates the liquid medicine to produce an aerosol. Inside the
eFlow is a stainless steel membrane that has thousands of tiny holes which make a fine mist that
is breathed in and out of your lungs. When the treatment is done, there will be no medicine left.
eFlow is a nebulizer and an air compressor all in one.
How do I put my eFlow Nebulizer together?
The eFlow nebulizer has several parts. The medicine reservoir is attached to the aerosol chamber
by a hinge. By gently pulling up on the tab of the reservoir you will release the aerosol chamber.
Gently touch the plastic outer ring of the aerosol head and press the two bendy plastic tabs on the
sides to insert it into the reservoir. Do not touch the metal part of the aerosol head. Next, press
the blue inspiratory valve into the groove on the aerosol chamber with the letters “VMQ” facing
the mouthpiece. Snap the nebulizer closed. The medicine cap has two parts: a cap and a seal.
Remove the seal from the cap using both hands with the ridges facing upwards; press down on
the center of the cap. To put the seal back, have the rubber valve facing up like a bowl. Line up
the four snap locks with the 4 prongs and push up into the cap.
What powers my nebulizer?
eFlow can be powered two ways:
1. The base or control unit contains 4 AA batteries to make it easy to carry with you.
2. It can also be plugged into AC Power. Remove the eFlow from the cradle and snap the
cord onto the rear underside of the eFlow. Slide the other end of the cord into the cradle
making contact with the metal power plate. Turn the eFlow on.
How do I do my treatment?
Before beginning the treatment, wash your hands with soap and warm water, or use anti-bacterial
hand gel, to reduce the risk of infection.
The medicine needs to be at room temperature. Place the nebulizer into the control unit as far as
it will go. Pour the medicine into the reservoir and close the medicine cap by lining up the tabs
with the slots in the reservoir. Turn the cap clockwise as far as it will go. Press and hold the
On/Off button for one second. Once you hear a beep and the light turns green, the eFlow is on.
Mist will appear from the mouthpiece. Close your lips around the mouthpiece and take slow
deep breaths in through your mouth. Hold the breath briefly on each inhale. Exhale slowly.
Hold the eFlow level. If the eFlow is tipped, it will sound two beeps and two green lights will
flash. The eFlow will shut off after 30 seconds but can be started again once the eFlow is level
and the start button pressed again.
How will I know when my treatment is done?
When all the medication has been inhaled the “treatment complete alarm” will sound. This is 2
beeps and 2 green lights. The eFlow will shut off by itself. If you must stop the treatment at any
point in time, press and hold the on/off button for one second. To begin again, press and hold the
on/off button for one second. After each treatment, take it apart for cleaning.
How do I clean eFlow?
The eFlow needs to be cleaned as soon as possible after every treatment with liquid soap. Do not
use “white” liquid soap such as Ivory® dish soap or antibacterial soaps as these may contain
additives that are harmful to eFlow.
1. Remove the medicine cap, cap seal, and mouthpiece.
2. Release the aerosol chamber by pulling up on the tab of the medicine reservoir.
3. Remove the aerosol head without touching the metal part and remove the inspiratory
4. Rinse all the pieces under running warm tap water for 10 seconds.
5. Rinse both sides of the aerosol head for 10 seconds on each side to prevent clogging and
make sure it is working.
6. Wash the aerosol head in soapy warm tap water separately to avoid other parts from
touching the metal part. Wash the other parts in the same water.
7. The final rinse is with sterile water and air dry on a clean lint free towel.
If you are using the Trio® or E-Rapid E-flow® devices for several different medicines, use
separate handsets for each medicine or different screens. If you do not have separate handsets,
repeat steps 1-4. If using the Altera E-flow®, use only with Cayston®.
How do I disinfect eFlow?
Always clean the eFlow first. Then disinfect using the cold or heat method below.
1. Control III
2. Soak in 3% hydrogen peroxide for 30 minutes. Make sure equipment is completely
3. Rinse all the parts well in sterile water. To make sterile water, boil your tap water for
5 minutes. Let the water cool. You can make up a gallon of water at a time, but only use
it once. Do not pour used water back into the gallon. Air-dry on a clean towel.
1. Electric steamer such as Nuk Quick ‘n Ready®
2. Do not microwave.
The control unit can be wiped down with a damp cloth. Avoid liquids on the inside of the
