Cough Assist Machine
The cough assist machine copies a natural
cough. It slowly sends a large volume of air
to your lungs, like a normal deep breath
when you breathe in (positive pressure).
Then it quickly reverses the flow of air and
mucus (negative pressure). The cough assist
machine makes your cough more effective.
It helps your airways stay clear, to decrease
the chance of respiratory infections.
Getting Started
We will help you to set up the machine and
teach you to make needed changes. You may
start with lower pressures to get comfortable
with the therapy. You should know that the
lower pressures may not be effective.
A cough machine breath is made up of an
inhale time, exhale time, and a pause time.
A normal treatment is 4 sets of 5 breaths.
You may do more or less cough sets. It
depends on how well you are clearing
mucus. Between each sequence you may rest
for 20-30 seconds or more. This resting time
gives your caretaker time to remove mucus
in your mouth and nose.
How do I adjust the phases of breathing?
Each phase of breathing is set so that you
can get the air in and out of your lungs with
comfort and have a pause time to keep
coughing, if needed.
1. Set the inhale time knob at 1 second.
2. Set the exhale time knob at 1 second.
3. Set the pause time knob at 1-2
seconds.
4. Set the inhale flow knob at the 3
squiggly arrows (full flow).
How do I use the cough assist machine?
•Before you start the treatment, wash
your hands with soap and warm
water or use anti-bacterial hand gel.
This decreases the risk of infection.
•Check to make sure the inspiratory
(positive) and expiratory (negative)
pressures are set. Start at +20/-20 and
slowly increase to +40/-40, or as
instructed by your provider.
•Test the machine by taking off the
face mask or mouthpiece from the
tubing. Hold the tubing firmly
against a flat surface.
•Turn on the machine.
•Set the manual/auto switch to auto.
The unit will then cycle from the
positive to negative pressure and
back to zero for the pause on its own.
•Put the mask or mouthpiece tightly
on your face or in your mouth so that
no air leaks out. If you use a
mouthpiece you may need to use a
nose clip to prevent air leakage.
•As you breathe in, the machine will
help by giving a big breath of air.
This breath will end at the time set
on your machine.
•As you breathe out, the machine will
help by sucking the air and mucus
out. This helps your cough be much
stronger and remove mucus.
•Keep taking a set of 4-6 breaths from
the cough machine. Rest for 20-30
seconds. Cough out mucus that may
have loosened up.
•A well-fitting, soft seal mask is best
for less leakage. You may need to
support your head from behind
during breaths to help keep your

airway open. Firm pressure may be
needed.
•If you have a cuffed tracheostomy
tube, inflate the cuff during the
treatment.
How do I change the pressures?
You may change the pressures with help
from your provider. If you need to lower the
pressures, tell your provider.
•Remove the face mask or
mouthpiece. Hold the tubing firmly
against a tight surface.
•Turn on the machine.
•Turn the pressure knob to reach the
inhale and exhale pressures you
want. Turn the inhale pressure knob
to fine tune the inhale pressure set.
How do I adjust the flow?
If you feel there is too much air flow coming
from the machine when you take a breath in,
you can turn down the inhale flow.
•Set the inhale flow knob at the one
squiggly arrow (decreased flow).
How do I clean my equipment?
•Wash your hands.
•Take off the mouthpiece and wash in
dish soap (Ivory, Joy, etc.) and hot
water. Do not wash with your dishes.
•Rinse with hot tap water.
•Air dry on a clean towel until your
next treatment.
•The bacteria filter on the machine
cannot be washed. Replace it when it
is blocked with mucus or trapped
moisture.
•Unplug the device and wipe the
outside surface with a clean cloth
dampened with water and one of
these cleaners:
oMild detergent
o70% isopropyl alcohol
•Replace the mask if it becomes torn
or if you can no longer keep a good
seal.
The mouthpiece must be cleaned after
every treatment. If you use a mask, clean at
least two times a week or more often if
visibly soiled.
Controls on the Cough Assist Machine
•Power switch: ‘I’ symbol means on.
‘O’ symbol means off.
•Inhale: sets how long the positive
pressure is blowing air into the lungs.
•Exhale: sets how long the negative
pressure is sucking air out of the
lungs.
•Pause: sets the time between the last
negative pressure and next positive
pressure.
•Inhale flow: sets the amount of flow
needed during breathing in. There are
two settings: “full”or “reduced”. If
“reduced”flow is used, there is less
pressure.
•Inhale pressure/pressure: turn to
set inhale pressures.
•Manual/Auto: controls whether you
want the machine to switch between
pressures on its own, or you want to
do it by hand.
•Manual control: allows you to
toggle between inhale and exhale
when you are using the manual
setting.
