Effective chest wall compressions are essential to ensure a minimum of cerebral blood
flow during resuscitation, but manual compression maneuvers are not always
efficacious. The LUCAS system delivers chest wall compressions that comply with
international recommendations. Using transcranial Doppler ultrasound to measure
cerebral blood flow, we compared flow during the cardiopulmonary resuscitation of 6
patients before and after placement of the LUCAS device. Two of the patients in
cardiorespiratory arrest secondary to subarachnoid bleeding had no cerebral blood
flow with either manual or automated compressions. For the other 4 patients, cerebral
blood flow was better during the automated compressions from the LUCAS system.
