Puritan Bennett 840 Ventilator

8 Apr 2011
Ventilator failure due to a quality issue (a batch problem) in the Power Supply Unit.  

You may have encountered Ventilator Failure with the screening showing "Device Alert" and the event logs registering an error code of VN0016. Covidien informed that the failure was due to a quality issue with its PCB C04 in its PSU module ((Supplier is Tamura (Taiyo Yuden)) which relates to the 12V supply. The 12V rail was fluctuating at approximately 11.5V when it should have been a constant 12V. It further isolates the problem to a defective R30, 500 ohms potentiometer.

  7. My husband and I have been married for about 7 yrs now. We were happily married with two kids, a boy and a girl. 3 months ago, I started to notice some strange behavior from him and a few weeks later I found out that my husband is seeing someone. He started coming home late from work, he hardly cared about me or the kids anymore, Sometimes he goes out and doesn't even come back home for about 2-3 days. I did all I could to rectify this problem but all to no avail. I became very worried and needed help. As I was browsing through the Internet one day, I came across a website that suggested that Dr OKU can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and he did a spell for me. Two days later, my husband came to me and apologized for the wrongs he did and promised never to do it again. Ever since then, everything has returned back to normal. My family and I are living together happily again.. All thanks to Dr OKU. If you need a spell caster that can cast a spell that truly works, I suggest you contact him. He will not disappoint you. This is his Email: (okutemple@gmail.com) or WhatsApp him (+2348163425519)

Nature will continue to bless you Dr Zico more abundantly for the good work you are doing in peoples life by curing them from different type of diseases. I will keep on testifying about your good work. I was living with diabetes type 1, 6 months ago and my doctor told me that there is no cure. I did not believe him and i kept my faith up hoping that one day i will be cured from this horrible disease. One day i saw a post on diabetes forum about a herbal doctor called Dr Zico on how he cured people from diseases with his root and herbs and i quickly contacted Dr Zico on his email and explained my problem to him and he told me not to worry that he is going to cure me and truly he prepared the herbal medicine and sent it to me through UPS and gave me instructions on how to take it. After three weeks of taken the herbal medicine , i went to my doctor for checkup and my diabetes result show Negative and my doctor told me that there is no trace of diabetes in my body and the diabetes is completely gone. If You are out there with any form of sickness or problem,you can also be cured from any type of diseases by contacting Dr Zico on his Email: zicoherbalhome@gmail.com
