Additional Manufacturer Narrative
For g4: pma/510(k): premarket submission number not available/not released.The customer's complaint that the autopulse nxt platform (sn (b)(6)) could not be used because the pin got jammed was confirmed during the functional testing and the archive data review.Although the reported complaint of pins got jammed was not exactly replicated, the nxt platform could not be operated because spools move out of position (not at home) and prevent the user from connecting the pin into the spool shaft.The archive data indicated no significant discrepancies.There were multiple on/off sessions recorded around the event date, but no compressions were delivered, confirming the reported complaint.Preliminary functional testing could not be performed due to the spool in the guard port being not reached to install the band pins because the spools moved out of position, confirming the reported complaint.The spools were returned to the home position to address the reported complaint.The platform was tested using the mztf (medium zoll test fixture) and operated for 10 minutes with no faults or errors being detected.The autopulse platform functioned appropriately and performed as intended.Following service, the autopulse nxt platform passed the final tests without issues.Historical complaints were reviewed for service information related to the reported complaint, and there was no previous history of complaints reported for the autopulse nxt platform with sn (b)(6).The death was not related to the autopulse device.The autopulse is used as an adjunct to manual cpr, adjunctive use only indication is prominently displayed on device labels and in the device manual.The benefit of using the autopulse is that it in part substitutes mechanical compressions for the physical labor of manual chest compressions when effective manual cpr is not possible.If the autopulse did not start or unexpectedly stops compressions, rescuer should revert to manual cpr, which is the standard of care.The autopulse is intended to be used as an adjunct to manual cpr on adult patients.In case of stoppage of autopulse the trained user reverts to manual cpr.The transition from autopulse to manual cpr by trained users is similar to the time necessary for rescuer rotation and presents the same workflow as manual cpr.Hence, based on available information, the patients' outcome was not negatively impacted by the interruptions when compared to standard of care manual cpr.According to multiple studies, out-of-hospital cardiac arrest (ohca) is considered one of the leading causes of death in industrialized nations, with a significant number of deaths occurring outside of a hospital setting, making it a major public health concern; this information is supported by research from the cdc, studies on global mortality rates, and data from various cardiac arrest registries.Survival to hospital discharge after non-traumatic emergency medical services-treated cardiac arrest with any first recorded rhythm was around 10% for patients of any age (mozaffarian, circulation, 2016; ebiomedicine 2023).Death is an expected outcome for ohca.
