Manufacturer Narrative
A purchase order (po) was sent to the customer and is currently pending the return of this documentation for shipment of a replacement coil cable kit. Therefore conclusion (#11) was selected as the investigation is not yet complete. The potential impact to a patient has been reviewed and the risk level has been assessed as medium (non-serious injury). The merge hemo user manual includes a guide on the communication between the pdm and the hemo monitor pc, equipment care guide, and tips on frequently asked questions. Per hemo-6373 merge hemo 10 user manual: (p. 54) communication: record station when a command is issued by touching or clicking an icon on the client pc, the hemo monitor pc responds. Physiologic monitoring is accomplished by these two computers joined via unique communication protocols. There are three icons on the bottom of the hemo monitor, left of the time display, that are displayed as visual indicators of system status. The patient name is displayed at the top of the screen and the day, date, and time are displayed at the bottom of the screen. (person) this icon appears to indicate communication between the hemo monitor pc and the patient data module (pdm). If there is a problem with any of the functions represented by the above three images, the icon color will switch to red. (p. 363) pdm 1. Check the physical condition of the pdm and its cleanliness. 2. Ensure that the calibration is current (according to the round sticker on bottom). If needed, order a replacement. Factory calibration is done before the unit is shipped. If the site requires the calibration of the unit to be checked, a transducer should be connected to a channel and 100 mmhg applied to the transducer with a mercury manometer. Ensure that it is within the ±1% tolerance that is allowed by the manufacturer. If the unit is outside of this specification, it should be returned. General: inspect overall physical condition of the system components, peripherals, and interconnecting cables. Perform any corrective actions required. (p. 365) problem: an application (the hemodynamics application or an external application) is frozen. Resolution: press ctrl+alt+delete and click task manager. Find application in the applications list and click end task. It may take several seconds for the task to be stopped. Restart application to resume.
 
Event Description
Merge hemodynamics displays, measures, and records physiological data from a human patient undergoing a cardiac catheterization procedure. The system comprises the patient data module and the merge hemodynamics hemo monitor pc. The two units are connected via a serial interface. All vital parameters and evaluations are registered and calculated in the patient data module. This data is then transmitted to the merge hemodynamics hemo monitor pc via the serial interface. All data can be shown and monitored on the merge hemodynamics hemo monitor pc. The customer contact reported that on (b)(6) 2018, the waveform monitor output (hemo monitor pc) was freezing for 3 seconds during electrocardiogram (ecg) monitoring in lab 5. During this time, the patient data module (pdm) started buzzing and the patient icon at bottom of screen started flashing (indicating an interruption in the communication between the hemo monitor pc to pdm). After a few seconds, the system recovered, the flashing person icon stopped alarming and waveform monitor unfroze. The biomedical engineer reset the pdm, as well as power cycled the hemo monitor pc. There was a three minute delay while the hemo monitor pc was rebooted and the case resumed immediately. There was no indication of patient harm as a result of this issue. However, with merge hemo being rebooted and not capturing physiological data, there is a potential for delay in treatment that could cause harm to the patient. (b)(4).
