    Attached are the updated Beacon and GFG manuals stating CO calibration is acceptable every 6 months..  Below is the response from DNV after after we challenged the ruling and provided these docs.. 

    DNV HC NOTE:   DNV  HC has accepted the challenge and evidence for this Finding; however at the time of the survey supporting information was not presented to the surveyor to verify compliance to avoid the nonconformity. In line with the NIAHO Accreditation Process consistent with the expectations of CMS, all nonconformances identified during the survey will be cited.  Given the information provided, this finding(s) will be closed and be assessed for continual compliance at the next annual survey.

    Thanks for the information. It's odd though, I just received an email a few weeks ago from GFG confirming they recommend monthly calibration. They didn't mention this new or updated procedure at all. 

    Attached is what I was given.

    So they give some caveats in this manual regarding when the calibration interval can be moved out to every 6 months.  

    The calibration interval can be extended to 6 months (maximum), when these requirements can be met:

    1. The monitors are in a controlled environment

    2. The monitors are in good working condition

    3. The CO sensor is replaced every two (2) years

    The Beacon Medaes manual also listed a few instances in which calibration must be performed at more frequent than 6 month intervals:

    * Recalibration of the CO transmitter is required prior to 6 months if any of the following conditions exist:

    • Last Calibration date cannot be verified or is unknown

    • Sensor Overexposed to target or interfering gases • Instrument has been subjected to misue or abuse

    • Sensor have been newly replaced or instrument has received any type of servicing

    • Whenever sensor response is in question

    So if you are a hospital facility with the ABL-4021 monitor it would seem you can push calibrations out to every 6 months provided you replace the sensor every 2 years, and meet the conditions in the Beacon Medaes manual (provided it is a Beacon Medaes med air system).  At least that is my takeaway

    One other note, most newer systems are now utilizing the 4035-22 CO transmitter if they are using GFG for CO monitoring purposes.  Has there been any feedback if this same 6 month interval change applies to the little blue puck that we see on most system built within the past 5-7 years?

    Rocky, thank you for posting that letter, I received a copy of that awhile back as well from GFG.  The 4035-22 transmitter manual doesn't list an interval at which it must be calibrated, so GFG provided that catch all letter to address their product line at large was my understanding.

    I spoke to GFG a few years back asking for the calibration interval on the 4035 and they told me "verbally" it was the same sensor as the 4021 (just different connection point wires vs pins) and the calibration frequencies are the same.
