Cpr quality assessment accounting for pause aspect

Abstract

Devices, systems, software and methods for CPR quality assessment. Patient data is received, derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. In some embodiments, a penalty value can be determined for at least one of the pauses, from at least one control factor unrelated to a constant linear dependence on the pause duration. An indicative value can be derived from the penalty value. In some embodiments, at least some of the pauses are classified in one or more pause groups, depending on how well they meet one or more classification criteria. The indicative value can be derived for one of the pause groups. The indicative value can be output, and / or an alarm can be emitted if it exceeds a threshold. CPR quality assessment can be improved in real time, and provide feedback for training.

In normal operation, the heart pumps blood through the various parts of the body. Sometimes the heart malfunctions, in which case it can beat irregularly, or not at all. The cardiac rhythm is then generally called an arrhythmia. Some types of arrhythmia may result in inadequate blood flow, thus reducing the amount of blood pumped to the various parts of the body. Some arrhythmias may even re...

AI Technical Summary

Benefits of technology

The patent text explains a new way to assess the quality of CPR chest compressions in real-time. This method takes into account the pauses that can occur during CPR and how harmful they can be to the patient. By doing so, rescuers can make better decisions in the moment and improve their performance for the next patient. Additionally, post-event analysis can also provide useful feedback for rescuers to improve their skills.

Problems solved by technology

Some types of arrhythmia may result in inadequate blood flow, thus reducing the amount of blood pumped to the various parts of the body.

In a SCA, the heart fails to pump blood effectively and, if not treated, death can occur.

When that happens, the heart does not pump enough blood to deliver enough oxygen to the vital organs.

A challenge with defibrillation is that the electrical shock must be administered very soon after the onset of VF.

That aspect is the answer to “for how much time were chest compressions actually being done while the patient needed them?” While that is true, a problem remains that interruptions in the chest compressions are not properly accounted for.
