    THE EXCESSIVE CONDENSATION FROM THE DEVICE WAS CONFIRMED BY ACTUAL TESTING OF THE DISPOSABLE DEVICE. THE EXCESSIVE CONDENSATION EXITING THE DEVICE WAS TRACED TO AN INTERACTION BETWEEN AIR AND THE WATER PATH WITHIN THE DEVICE'S DISPOSABLE HUMIDIFICATION CARTRIDGE. EXAMINATION OF THE HUMIDIFICATION CARTRIDGE REVEALED SIGNS OF HUMIDIFICATION MEMBRANE DISCOLORATION. FROM VAPOTHERM'S PRIOR INVESTIGATIONS THIS DISCOLORATION IS AN INDICATION OF DETERIORATION OF THE MEMBRANE WHICH COULD LEAD TO SUBSEQUENT LEAKING. THE CAREGIVER HAD MENTIONED THAT THE PATIENT WAS BEING TREATED FOR LONG TERM ON THE DEVICE BEFORE THIS ISSUE OCCURRED. BASED ON OUR PAST EXPERIENCE THE MEMBRANE DETERIORATION COULD BE DUE TO THE FOLLOWING FACTORS: 1. PROLONGED USE OF THE DEVICE BEYOND THE RECOMMENDED LIFESPAN OF THE DISPOSABLE HUMIDIFICATION CARTRIDGE. THE QUALIFIED USE LIFE OF THE DISPOSABLE IS 30 DAYS. 2. USE OF NON-INHALATION-GRADE WATER IN THE DISPOSABLE CARTRIDGE. WE ARE WORKING WITH THE USER FACILITY TO UNDERSTAND THE SPECIFIC USE CASE SCENARIO. WE CONTINUE INVESTIGATING THIS COMPLAINT TO DETERMINE ROOT CAUSE. VAPOTHERM CONTINUES TO INVESTIGATE THIS ISSUE AND IN THE MEANTIME, WE ARE TRACKING AND TRENDING THIS ISSUE TO MONITOR OCCURRENCE. THIS IS CURRENTLY AN ISOLATED OCCURRENCE OF THIS ISSUE WITH NO OTHER SIMILAR INCIDENTS IN THE PAST 12 MONTHS (THE PERIOD OF LOOK BACK). RISK ASSESSMENT RESULTS: THIS IS AN ISOLATED INCIDENT INVOLVING THE VAPOTHERM PRECISION FLOW DEVICE. THERE HAVE BEEN NO OTHER SIMILAR COMPLAINTS RESULTING IN PATIENT INJURY FROM THIS LOT OR ANY OTHER LOT OF DISPOSABLES WITHIN THE PAST 12 MONTHS, FROM AUGUST 2023 TO JULY 2024 (THE PERIOD OF LOOK BACK). DURING THIS PERIOD, VAPOTHERM HAS SHIPPED HUNDREDS OF THOUSANDS OF DISPOSABLES WORLDWIDE, WITH TENS OF THOUSANDS SHIPPED IN THE UK. PER RISK MANAGEMENT PROCEDURES IN PLACE AND THE HAZARD ANALYSIS FOR THIS DEVICE, THE OCCURRENCE OF THIS ISSUE IS LESS THAN 0.005% IN THE UK AND LESS THAN 0.0005% WORLDWIDE. THIS PUTS THE OCCURRENCE IN THE 'IMPROBABLE' CATEGORY. THE HARM ASSOCIATED WITH THIS ISSUE HAS THE SEVERITY OF 'SERIOUS'. THE OVERALL RISK BASED ON THE SEVERITY OF SERIOUS AND THE OCCURRENCE OF IMPROBABLE IS R1. THE DEVICE CONTINUES TO MEET RISK MANAGEMENT EXPECTATIONS REGARDING THE POTENTIAL FOR 'INGRESS OF WATER IN THE PATIENT AIR PATHWAY.' THE LIKELIHOOD OF PATIENT INJURY REMAINS LOW FOR THE FOLLOWING REASONS: 1.THE VAPOTHERM PRECISION FLOW DELIVERS THERAPY VIA A NASAL CANNULA IN AN OPEN SYSTEM. 2.THE INSTRUCTIONS FOR USE ADVISE REGULAR OBSERVATION OF THE PATIENT AND PATIENT INTERFACE FOR EXCESS WATER TO REDUCE THE RISK OF ASPIRATION OF CONDENSED WATER FROM THE BREATHING CIRCUIT. IF WATER IS DETECTED, THE PATIENT INTERFACE SHOULD BE PROMPTLY REMOVED. 3.CLINICIAN'S ARE FAMILIAR WITH MONITORING FOR RAIN OUT/CONDENSATE, AND EXCESS WATER IS EASILY VISIBLE, AS WAS THE CASE IN THIS INSTANCE. 4.THE INSTRUCTIONS FOR USE EMPHASIZE THE NEED FOR ADDITIONAL PATIENT MONITORING, INCLUDING PULSE OXIMETRY, DURING DEVICE OPERATION. 5.THE DISPOSABLE DEVICES ARE QUALIFIED FOR USE FOR 30 DAYS. RISK ASSESSMENT IS DOCUMENTED IN THE DEVICE'S HAZARD ANALYSIS, WHICH IS REGULARLY MAINTAINED THE EXCESSIVE CONDENSATION EXITING THE DEVICE WAS POTENTIALLY DUE TO MISUSE OF THE DEVICE. VAPOTHERM CONTINUES TO INVESTIGATE TO CONFIRM ROOT CAUSE. VAPOTHERM WILL TRACK AND TREND SIMILAR INCIDENCES AND ENSURE DEVICES CONTINUE PERFORMING WITHIN THE EXPECTATIONS OF RISK MANAGEMENT. SUBMISSION OF THIS MEDICAL DEVICE REPORT AND THE FDA'S RELEASE OF THAT INFORMATION IS NOT AN ADMISSION THAT PRODUCT, USER FACILITY, DISTRIBUTOR, MANUFACTURER, OR MEDICAL PERSONNEL CAUSED OR CONTRIBUTED TO THE EVENT.
