    (B)(4). METHOD: ONE OF THE COMPLAINT MR290V VENTED AUTOFEED HUMIDIFICATION CHAMBERS WAS RETURNED TO FISHER & PAYKEL HEALTHCARE IN (B)(4) AND WAS VISUALLY INSPECTED. RESULTS: VISUAL INSPECTION REVEALED THAT THERE WAS A BREAK IN THE FEEDSET TUBING AT THE CONNECTION TO THE CHAMBER. THE SURFACE OF THE BREAK WAS ROUGH (NOT SMOOTHLY CUT). A LOT CHECK REVEALED NO OTHER COMPLAINTS OF THIS NATURE FOR LOT NUMBER 120822. CONCLUSION: THE DAMAGE APPEARED TO BE CAUSED BY THE TUBE BEING PULLED AWAY FROM THE CHAMBER, POSSIBLY DUE TO THE FEEDSET BEING CAUGHT OR UNDER TENSION. THIS IS EVIDENCED BY THE ROUGH BREAK. WE HAVE CONDUCTED EXTENSIVE TESTING OF THE MR290 CHAMBER, WITH PARTICULAR EMPHASIS ON FEEDSET BREAKS. SIGNIFICANTLY WE HAVE NOT BEEN ABLE TO REPLICATE FAILURE OF THE FEEDSET TUBE AT THE CHAMBER DOME IN ANY OF OUR TESTING. THE SPECIFICATION FOR THE CHAMBER REQUIRES THAT THE FEEDSET TUBE SHOULD HAVE A BREAKING STRAIN OF 30 NEWTONS. DURING PRODUCTION, PULL TESTING OF THE FEEDSET STRENGTH AT BOTH SPIKE AND DOME END IS PERFORMED EVERY HOUR ON MR290 CHAMBERS FROM EACH PRODUCTION LINE. ADDITIONALLY, ALL CHAMBERS ARE PRESSURE TESTED BEFORE THEY LEAVE THE PRODUCTION LINE AND ANY HOLES OR LEAKS IN THE FEEDSET ARE IDENTIFIED DURING THIS PROCESS. CHAMBERS THAT FAIL ANY OF THESE TESTS ARE DISCARDED. THIS SUGGESTS THAT THE DAMAGE OCCURRED AFTER THE SUBJECT MR290 WAS RELEASED FOR DISTRIBUTION. THE USER INSTRUCTIONS WHICH ACCOMPANY THE MR290 CHAMBER STATE THE FOLLOWING: "SET APPROPRIATE VENTILATOR ALARM." "PERFORM A PRESSURE AND LEAK TEST ON THE BREATHING SYSTEM AND CHECK FOR OCCLUSIONS BEFORE CONNECTING TO A PATIENT." (B)(4).
