ECD feedback
Weil SCC ™ - The first mechanical chest compressor device to deliver
real-time data feedback. ECD (Effective Compression Depth) enables
assessment of depth and effectiveness of compressions.
ERC/UK Resuscitation guidelines recommend the depth of chest
compressions should be 5 cm, also compressions should be
uninterupted and compression-ventilation (CV) ratio of 30:2 is used.
Weil SCC™ provides instant feedback for:
•
•
•
•
Effective Compression Depth
Compression Duration
Compression Frequency
Compression Mode
“The recommended depth of compression is at least 5 cm (not more than 6 cm) and the rate is at least 100
compressions min (not more than 120 min). Allow the chest to completely recoil in-between each compression”.
ERC/UK Resuscitation Guidelines
Intelligent data analysis
Weil SCC™ - PC software provides data storage for up to 10,000 patient
records including;
•
•
•
•
Effective Compression Depth
Compression Duration
Compression Frequency
Compression Mode
All data can be transmitted via WiFi or Bluetooth to PC.
The dedicated software enables data synchronisation and data analysis
for assessment by clinicians.
“Rescuers begin CPR if the victim is unconscious or unresponsive and not breathing normally (ignoring occasional
gasps). A single compression-ventilation (CV) ratio of 30:2 is used by the single rescuer of an adult or child (excluding
newborn) out of hospital, and for all adult CPR”.

3D Compression Technology
High Efficiency - Less Traumatic
3D Compression technology combines ‘both’ cardiac and thoracic pump theory. The patent is owned by Weil Institute of Critical
Care Medicine (fig a).
External Exertion Pressure
Internal Thoracic Pressure
Lateral Released Pressure
fig a. patent - US 7060041 B1
fig b. 3D Compression theory
In addition to vertical chest compression between sternum (chest bone) and spine, the torso restraint is placed underneath
and around the patient to firmly secure the compressor on the patient; this allows compression of the whole chest cavity to
promote instant blood circulation. Resulting in highly effective three dimensional chest compression (fig b). Research studies
have confirmed that 3D chest compression technology can shorten the compression cycle and the number of electrical shocks.
Importantly using Weil SCC™ technology minimises rib fractures and neuro deficit. Weil SCC™ technology is non-invasive,
improves hemodynamic efficacy during CPR and is the closest method to resemble the heart’s 3D pumping action.

Technology advances....
Within emergency medicine there is a requirement for high quality CPR. There are known limitations with manual
CPR; but the emergence of technologies in recent years started to address the requirements to improve
CPR and deliver new chest compression technology, to improve blood flow whilst performing CPR.
The main objective being to revive the patient and improve blood flow to the heart and brain.
3rd Generation Technology
3rd Generation mechanical chest compression technology:
3D Compression
Cardiac and Thoracic Pump Theory
External Exertion Pressure
Internal Thoracic Pressure
‘3D Compression’ - 100% of the chest cavity is enclosed with
the torso restraint. In addition it provides multi-point
compression, the whole chest cavity is compressed
to simulate heart pump function
Lateral Released Pressure
2nd Generation Technology
2nd Generation mechanical chest compression technology:
Load Distributing Band Compression
Thoracic Pump Theory
External Exertion Pressure
Internal Thoracic Pressure
Lateral Released Pressure
‘Load Distributing Band Compression’ - major step forward
from single point compression, it squeezes a wide area
of the chest (50%) with multi point compression
spreading out the force of compression
1st Generation Technology
1st Generation mechanical chest compression technology:
Single Point Compression
Cardiac Pump Theory
External Exertion Pressure
Internal Thoracic Pressure
Lateral Released Pressure
‘Single Point Compression’ - simulates hands-only
compression, single point compression, high impact force

Portable, Easy to use and Rapid application
Rapid application for treatment of sudden
cardiac arrest patients, apply immediate
manual CPR, followed by effective continuous
uninterrupted mechanical chest compression
•
•
•

“It is well documented that interruptions in chest compression are common and are associated with a reduced
chance of survival. The ‘perfect’ solution is to deliver continuous compressions whilst giving ventilation
independently”.

“There is increased emphasis on the importance of minimally-interrupted high-quality chest compressions throughout any ALS intervention: chest compressions are paused briefly only to allow specific
interventions”.
