Fisher and Paykel Healthcare AIRVO 2
Q: Does anyone have a PM procedure and what is the frequency of PM? Or, are you risking out or doing AEM?
A: I took a look at their website but could not find a service manual. The closest thing I could find to maintenance requirements is this:
- Controlled oxygen delivery (when required)
- Oxygen from a concentrator or cylinder can be added. An in-built ultrasonic analyzer requires no calibration, service or replacement.
If it were me, I would contact the vendor and ask about preventive maintenance.
A: Per the technical manual, “Arivo 2 humidifiers do NOT require routine servicing or calibration.” There is a performance check option, however; there’s no manufacturer requirement to carry out these checks on a routine basis as stated in the technical manual. This was also confirmed via email with F&P’s quality and regulatory specialist and we have that correspondence on file in case the no-service/PM strategy is questioned by surveyors. You may wish to do the same. In the meantime, I’ll send the technical manual to MedWrench’s admin for posting.
A: The manuals may be found online at bit.ly/3fAoXNt.
Toshiba Aquilion 64
Q: I started off with a gantry rotation error which led me to changing the rotation servo amp. After changing this, the gantry panel greyed out the bed in and out positions and would only go down just below 0 to 005 and not any lower. I did all couch calibrations on GTSA and that did not fix it. Does anyone have an idea of what could cause this issue?
A: I would check the KGTSP power board. There are a few relays on that board that can go bad. I’ve always replaced the board but you can try cleaning the relays.
A: Check the couch vertical encoder string and horizontal photodiode sensors. But, I also recommend checking KGTP’s power board. And since you replaced the GTS board and the battery make sure the “Zero Adjustment” was done properly.
Iris International StatSpin Express 4
Q: The service light is on.
A: The service light on indicates the drive system has reached a predetermined number of cycles and the drive should be replaced before it completely fails. Contact Ozark Biomedical, if I’m correct they will do rebuilds on these for a flat fee.
A: Yeah, there is a timer chip on the main board. Once it reaches the limit, the service light turns on. The motor replacement kit comes with a new chip. It’s not that expensive and it’s easy to replace. Having the motor rebuilt won’t get rid of the light; that chip needs to be replaced as well.
A: My name is David and I work for Ozark Biomedical. I would be happy to assist you in this issue.
It is important to emphasize that the cycle count limit is to require customers to inspect their drive assembly and replace their rotor assembly after a set number of runs. This limit was determined by the OEM, based upon the relative lifespan of the average StatSpin Express 4 rotor. Iris found the rotor for the Express 4 could develop stress cracks in the center plate or other components, resulting in vibrations and eventual complete failure during operation. I have personally worked on several StatSpin Express 4 units that have had their rotors fail during operation and can attest to the damage. I highly recommend customers consider the condition of their rotor before resetting the cycle limit.
To reset the cycle limit: Press and hold the “3 & 5” minute buttons simultaneously while powering on the unit, continuing to hold them for approximately 6-10 seconds. While doing this, the unit will produce multiple audible beeps. After awaiting the defined time, release the buttons and power cycle the unit. The cycle limit will have been reset.
Let me know if I can assist you further.
