The investigation into the death of singer Giorgos Mazonakis is focusing on data recorded by the plasmapheresis machine, a technical trace that, according to Greek authorities, may clarify what happened at the clinic during the most critical minutes. From the first interruption of treatment to the emergency call, 49 minutes elapsed, a time gap expected to be central to the checks.
What the machine data show
According to the Hellenic Police investigation and information published by protothema.gr, the machine was activated at 14:14, but at that moment the blood exchange with the patient had not yet begun.
Preliminary data show that Mazonakis is believed to have arrived at the clinic at around 13:50-14:00. This time frame is being compared with testimony and other evidence to accurately reconstruct the chain of events.
The first alarm and the actual start of the procedure
The system’s first alarm was recorded at 14:23, just nine minutes after the machine was activated. According to investigators’ assessment, such a signal may be linked to problems in the tubing or to changes in the patient’s pressure, but these remain lines of inquiry and not official conclusions.
The actual blood exchange procedure began at 14:37. This exact time is considered a key element, as it marks the effective start of treatment and will be verified with camera footage, photographs, testimony and other electronic data.
Shutdown at 15:22 and the series of alarms
The most critical moment in the chronology was recorded at 15:22, when the machine stopped the blood exchange process. From that moment until 15:45, the system recorded three more alarms.
According to the data being examined by investigators, these alarms were accompanied by the absence of a heartbeat. This is one of the most sensitive points in the case file, as the investigation is trying to determine not only what the machine was signaling, but also what actions were carried out at the clinic during that interval.
The restart attempt and the delay until emergency services were called
At 15:45, according to the version under investigation, the machine was again given the command to start operating. However, the machine stopped almost immediately after the restart attempt.
Emergency services were called only at 16:11. This means that 49 minutes passed from the first interruption of treatment at 15:22 until the request for emergency help, a period during which the machine recorded repeated alarms and an unsuccessful restart.
Greek authorities are now comparing this digital chronology with the other evidence collected to understand when Mazonakis’s condition deteriorated and how the medical staff responded.
The main question remains the interval between the successive alarms and the emergency call, a time gap that could weigh heavily on the conclusions of the investigation.
