Lucas has shown to significantly improve quality and increase consistency of compressions compared to manual CPR, both at the scene, during ambulance or helicopter transportation, as well as in the cath lab setting.
In pre-hospital use, at the scene and during transportation. Lucas has shown to significantly increase chest compression fractions to around 90% compared to manual CPR.
Lucas has shown to improve blood flow to the brain compared to manual CPR in pre-hospital patients (60% increase as measured by Doppler).
These findings are consistant with results from experimental studies. In addition, brain circulation as measured by cerebral oximetry during prolonged Lucas compressions has shown values exceeding previously published values during manual CPR. Both human and experimental studies have shown that Lucas can produce coronary perfusion pressures of over 15mmHg during prolonged CPR, better than manual CPR.
Lucas has shown to significantly increase EtCO2 levels, compared to manual CPR in a prehospital, controlled clinical study as well as in experimental studies.
