Figure 1. The CPAP Concentrator
Oxygen concentrators are machines that extract nitrogen from atmospheric air, resulting in an
output of almost pure oxygen. CPAP is continuous positive airway pressure, which can assist
children with severe respiratory distress. The bubble-CPAP concentrator delivers both oxygen and
continuous positive airway pressure, the level of which depends on the distance the tubing is
under the water in the bottle.

Setting Up the Bubble-CPAP Concentrator
Follow the steps below to use the bubble-CPAP concentrator:
1. Position the concentrator so that it is at least 30 cm away from walls or curtains, so that the
inlet opening at the back is not obstructed.
2. Plug the power cord into the mains electricity supply, and turn on the concentrator.
3. Switch on the concentrator (switch on the console). A yellow light should turn on and remain
lit for a few minutes (usually within 10 minutes) until the concentration of the gas supplied
reaches and exceeds 85± 3% O₂. The yellow light should then turn off after this time, showing
that the concentrator is running correctly.
4. Fill the bottle to the level indicated with boiled water that has been allowed to cool, and screw
the lid back on.
5. Connect the inspiratory limb of the circuit to the main gas outlet.
6. Connect the expiratory limb of the circuit to the bottle.
7. Dial up the level of CPAP required: start at 7 cmH2O (see figure below)

within the securement
line indicator
9. Dial the flows of air and oxygen required to see a constant stream of bubbles in the water.
Start with 5 L/min of oxygen and 5 L/min of air. Check and record the flows dialled and the
oxygen concentration this provides. A total flow of 10 L/min is sufficient in most cases to
deliver CPAP, which you can see by continuous bubbling in the bottle.
10. Check the child for signs of respiratory distress, check the SpO2, and check if there are bubbles
in the bottle.
a. If the SpO2 is below 90% or the child has severe respiratory distress, first increase
the CPAP level to 8 or 10cmH20 and then, if no response the oxygen flow meter to
as much as 8 L/min.
b. If there are not continuous bubbles, check the nasal prongs are attached properly,
and reposition them so they fit snugly inside the nostrils.
c. If there are still not continuous bubbles, check for leaks along the circuit, and adjust
the oxygen or air flows according to the chart below.

Trialling patients off CPAP and when to stop CPAP
At least once each day, children in the ward who are clinically stable (have no emergency signs and
SpO2 >90%) should be disconnected from CPAP for 10–15 minutes, and carefully examined for
changes in clinical signs and SpO2, to assess whether supplemental oxygen and CPAP is still
required. Trials off CPAP are best done first thing in the morning, when there is likely to be
adequate staff to observe the child throughout the day. If trials off CPAP are started in the late
afternoon, low staff numbers overnight and the oxygen desaturation that sometimes occurs
during sleep mean that there is a risk of hypoxaemia developing unrecognized overnight.
Children who have an SpO2 <90% while still on CPAP or who are unstable or very unwell should
not be given trials on room air.
Before a trial off CPAP, the SpO2 should be checked to determine if the trial is safe
(i.e. SpO2 >90%). The child should then be disconnected from the oxygen source and observed
carefully to avoid any adverse complications of hypoxaemia. If severe hypoxaemia (SpO2 <80%),
apnoea or severe respiratory distress occurs, children should be immediately restarted on oxygen.
Some children will become hypoxaemic very rapidly when they are taken off oxygen, and this is a
marker of very severe disease and a high risk of death. Parents and nursing staff should be advised
to watch the child to see if he/she develops cyanosis or severe respiratory distress.

If the SpO2 is 90% or more after a trial on room air, they should remain off oxygen and the SpO2
should be rechecked after one hour, as late desaturation can sometimes occur.
If the SpO2 on room air is <90% or there is severe respiratory distress they should go back on
CPAP.
Any child who appears to deteriorate clinically should have their SpO2 checked to determine
whether they need oxygen. Children with acute respiratory disease should not be discharged until
their SpO2 has been stable at 90% or more while breathing room air for at least 24 hours, until
danger signs have resolved, and until appropriate home treatment can be organized.
Cleaning of the Circuit Tubing and Bottle
This is essential to reduce the risk of cross-infection. This should be done after every patient has
used the CPAP, and weekly if the same child is on CPAP for over a week. A spare circuit is essential
to replace the one that is being cleaned without interruption to the child’s treatment.
The CPAP circuit (inspiratory and expiratory limb, bottle and lid and connections) must be
thoroughly cleaned as follows:
1. Wipe off any gross soiling. Clean first with detergent (soap) to remove gross contamination
(e.g. blood, sputum);
2. Rinse with water that has been boiled and allowed to cool to tepid. Let it dry
3. Disinfect before re-using.
• Staff cleaning the equipment must wear protective clothing to avoid splash exposure or
contact with dirty equipment: wear apron, gloves and glasses.
• Good ventilation of the area is needed where you are cleaning the equipment
What You Need:
• Soap for initial clean
• Disinfectant solution: (sodium hypochlorite 0.05% or household bleach, diluted to
0.05% hypochlorite. The household bleach bottle will indicate its strength, dilution is
essential)
• Sink or buckets to clean equipment
• Brush to clean both inside and outside of circuit. All brushes and cleaning implements
must be properly cleaned after use – soap water and drip dry
• Gown or waterproof apron, mask and water-proof gloves
• Drying rack

How to Wash and Disinfect
1. Wash hands
2. Prepare detergent (soapy water) and disinfectant solution wearing personal protective
equipment (PPE): gown or impermeable apron as a minimum, eye protection and
surgical mask for bleach solution
3. Wash first in soapy water, to remove blood and respiratory secretions. In clean sink or
bucket brush the equipment under water to prevent splash and ensure all visible soiling
is removed, rinse with water that has been boiled but allowed to cool to tepid
4. Let dry
5. Wash next in diluted bleach or disinfectant. Bleach needs one hour of soaking. Soak all
items together, do not keep putting one in and taking one out. Once used bleach
should not be re-used or kept in storage, discard after use.
6. Rinse with water that has been boiled and cooled to tepid (rinse also inside, for
example, using a sterile syringe), let it drip dry over the sink, do not leave it coiled on
the sink.
7. Remove all protective gear (apron, gloves, mask) and wash hands thoroughly
8. Check that there is no pooled water in the circuit. Store the circuit and bottle in a clean
plastic bag (labeled and dated). Store in the dry and clean area (separate from a soiled
equipment area)
Routine Cleaning and Maintenance of the CPAP-Concentrator
Each week the oxygen concentrator will require approximately 30 minutes of attention.
Concentrators have a large particulate filter over the air inlet opening (usually at the back of
freestanding or portable models). This filter stops dust and other airborne particles from entering
the unit. The filter should be removed and cleaned in warm soapy water, completely dried with an
absorbent towel and replaced. Have a spare dry filter to replace with so there are minimal
interruptions to the concentrator function.
The exterior of the oxygen concentrator should be cleaned with a mild disinfecting cleaning agent
or a diluted solution of bleach (usually 5.25% sodium hypochlorite). A solution in the range of
1:100 to 1:10 of bleach to water can be used effectively. Allow the solution to remain on the
surface for 10 minutes and then rinse off and dry.
