FIELD: medicine.
SUBSTANCE: group of inventions includes a system and method for providing feedback regarding chest compressions in cardiopulmonary resuscitation, an automated resuscitation device, machine-readable information storage media. System comprises a measuring unit, a processor, an indicator unit, a sensor for registering depth of chest compressions and a display for displaying a signal indicating depth of compressions. Automated resuscitation device comprises a chest compression device, system for providing feedback regarding chest wall compressions and a processor. Arterial blood pressure of the patient is obtained for a time period while cardiopulmonary resuscitation is being performed. Blood pressure cardiopulmonary resuscitation quality indicator is calculated. Cardiopulmonary resuscitation quality indicator is compared with a quality criterion determined as a threshold of the target interval. Low quality indication signal is transmitted, if the blood pressure cardiopulmonary resuscitation quality indicator is outside a quality criterion or a high quality indication signal is transmitted, if the blood pressure cardiopulmonary resuscitation quality indicator fulfills the quality criterion. Depth of compression of cardiopulmonary resuscitation is registered and a signal indicating depth of compression is displayed. Necessity of performing a step up and a step down of compression depth relative to a previously determined optimal compression depth is indicated. New optimal compression depth is selected based on the three cardiopulmonary resuscitation quality indicators obtained as the depth with the highest blood pressure cardiopulmonary resuscitation quality indicator value or as the smallest depth with a blood pressure cardiopulmonary resuscitation quality indicator at the cardiopulmonary resuscitation quality indicator value that exceeds a target blood cardiopulmonary resuscitation quality indicator value.
EFFECT: group of inventions permits optimal cardiopulmonary resuscitation of a patient by using blood pressure characteristics as a cardiopulmonary resuscitation quality indicator.
