SAFETY
NCCD is only to be used by trained personnel with competence
in CPR and with experience in handling of pressurised gas.
Incorrect use may cause injury to the paent and user.
Use of NCCD can increase ppO2 and atmospheric pressure in
closed systems.
Do not use oxygen (>22%), or gas mixture with a O2 content
over 22% as supply gas.
Make sure not to stretch or pull hoses [6+7] to and from the
hand control unit [4].
Do not compress the hand control unit [4-5] while connecng
gas. The NCCD piston foot [3] can move and cause a pinching
hazard. Apply NCCD before gas is connected.
Incorrect positioning will reduce quality of compressions and
may cause injury to the patient.
MALFUNCTION
If proper applicaon and use of NCCD is not possible,
start manual CPR immediately.
Recommended checks and acons when possible:
1. Verify 10 bar supply pressure.
2. Check unit for damage or loose couplings.
3. Tell us about your experience: [email protected]
Please include NCCD serial number (SN08…..), found
on the back of the piston house [1], with correspondence.

4
USE OF NCCD
NCCD is only to be used when CPR is initiated on adult
patients, and only by personnel that have sufficient CPR
training.
NCCD is not to be used if trauma is suspected or during
pregnancy.
Your gas outlet connection needs to be Hanson 600 series, ¼“
female coupling. If your gas connection is of a different model,
please contact NUI.
Do not modify the NCCD in any way.
Do not use NCCD if the case seal is broken or missing. Does not
apply to the training units.
The NCCD will function while submerged in water.

If proper application and use of NCCD is not possible,
start manual CPR immediately.

PRECAUTIONS
Maximum tension on pressurised hoses and ngs: 5 kg (49 N).
Max. distance [6] from paent to hand control unit [4-5]: 100 cm.
Maximum distance from paent to gas outlet [6+7] : 300 cm.
Maximum distance from paent to gas outlet using extension
hose [6+7+13]: 450 cm.
When connecng the NCCD QC [8] to gas outlet, make sure the
pressure release handle [5] is not compressed.
NCCD is to be used with pressurised HeliOx as drive gas at depth.
Compressed air can be used at surface. Use of air as drive gas can
signicantly limit the NCCD funconality in a hyperbaric
environment.
NCCD can be used along with debrillator pads from an AED.
Make sure to place the pads under the NCCD chest belt.
Aer use:
Aer use, make sure to disconnect the NCCD from the gas outlet,
and execute a couple of compressions to bleed o pressure from
the system. Be aware of pinching hazard.

A. Undress the paent’s upper body.
Cut clothes using included scissors [14] if needed.
B. Apply NCCD as instructed
on the following pages.
Image show NCCD applied.
APPLICATION OF NCCD

7
1. OPEN NCCD CASE
Break sealing. It requires 6 kg of force.
2. TAKE OUT NCCD
Remove the NCCD with chest belt [9] (black) from the
case. The belt is pre-aached to the right side of the
boom plate [2].
APPLICATION OF NCCD

8
3. BELT UNDER PATIENT CHEST
Place chest belt centered under
the paent’s back, posterior in
the middle of the back, between
the shoulder blades.
4. PLACE NCCD ON THE
PATIENT’S CHEST
Place the NCCD compression unit
1-3 on paent chest so that
the piston foot 3 is located
where your hands would have
been placed during manual CPR.
Make sure not to place the piston
foot to far down towards the
p of the sternum or too high up
on the chest. This could cause
injury to the paent or/and
cause insucient compressions.

5. FASTEN BELT
a) Thread chest belt through slot
in the boom plate 2
b) Tighten the belt so the
compression unit is secured
on the chest.
Fasten the Velcro 10, and make
sure it’s rmly fastened on both
sides. Use red markings 11 to
center the belt.
c) Adjust both sides if necessary.
Conrm that the NCCD is rmly
applied to the paent’s chest.
The NCCD shall not compress
the chest by applicaon.
Conrm correct placement of the
piston foot [3] according to the
hand placement used when
you are preforming manual CPR.

NCCD can provide sucient
compressions when the
paent is in a vercal posion
when the NCCD is secured by the
adjustable support strap 2.
Remove clothes from the paent
upper body, and fasten the NCCD,
skin ght around the chest (do not
compress the chest with the belt).
a) Remove the adjustable support
strap 2 from the package, and
hang it around the paent neck.
b) Aach the carabiner hooks to
the slots in the NCCD plate 2 as
shown in image b) and c).
The strap length and tension needs
to be adjusted so that it supports
the NCCD, not causing an angle
(perpendicular to paent frontal
plane), or causing a rotaon of
the NCCD.
c) Verify that the adjustable strap
is aached as shown in the image.

6. CONFIRM PRESSURE and ppO2
NCCD runs on pressurised gas.
Conrm 10 bar “over ambient” gas drive pressure.
Conrm that gas supply has approx. the same ppO2 as
compartment atmosphere.
7. CONNECT TO GAS
Locate quick connector (QC) [8] for gas connecon. Insert male QC
on NCCD into gas outlet female QC (as you would a BIBS mask).
USE OF NCCD

12
8. START COMPRESSIONS
Locate NCCD hand control unit [4]. Hold it as shown in the
illustraon. You might nd it necessary to hold the control unit
with both hands.
Compress handle all the way in and release it all the way out.
Conrm that piston is compressing the chest according to CPR
requirements. Repeat and connue preforming chest
compressions in accordance with current CPR protocol.
Not fully compressing and releasing the handle on the control
unit will cause insuccient chest compressions. Strive to
complete full compressions og decompressions using as much
me to compress the handle
as to release the handle on
the control unit.
