FDA's MAUDE database holds 1,690 reports that name the brand "Ht70 Ventilator" (cbk nou), received between July 2011 and June 2026; the manufacturer given most often on reports is Newport Medical Instruments. Spellings of one product vary from report to report.
13 reports arrived in the 12 months to August 2026, down 73% from 48 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (62.3%), injury (36.7%) and death (0.6%); across all ventilator, continuous, facility use reports (product code CBK) death is recorded in 1.1% and malfunction in 91.8%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are device displays incorrect message (17.7%), device operates differently than expected (14.7%) and no flow (10.6%). The patient problems coded most often are no patient involvement, low oxygen saturation and ventilator dependent. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
