Tone,
I will speak to our estates manager when I get back on Monday to find out whether any further pharmacy inspections were carried out. (I am assuming everything was done in accordance with HTM2020.)

Do you want to put money on that ?

I've spoken to Estates staff who think that air is piped round the hospital just to drive tools ! They seem to think that if it isn't Oxygen, then it isn't given to a patient !

Thanks you all. Our Pharmacist is principally responsible for medical gases and has been involved and is very helpful. We immediately started to run our vents off bottled Air and there was much lugging of G size cylinders. We added an extra HME filter to the inspiratory limb of the patient circuit and Microbiology took samples of the fluid coming through the air lines. (They didn't grow anything). Our AP-authorised person- was around commissioning the new site and was able to offer plenty of advice about the gas system. After the compressor was repaired, they flushed the system for some time to get the humidity down. However, the clinicians are still nervous about what may be left inside the vents and the risk to already compromised ICU patients. The Public Health labs at Colindale have recommended a strip down and we await the manufacturers price with interest. In the meantime we are still running those vents with extra HME filters (a fairly cheap precaution). Of course the Medical Gas system is provided and run by our PFI partner and there may be some contractual argy bargy. I will keep you up to date with the outcome.

You have to replaced filter dryer imeadiately otherwise all ventilator will be defective the pressure sensor its self.
for the anasthesia machine will disturb the flow sensor measurement and alarm will sound everytime or will defect the flow sensor who's using thermal platinum wire such as Drager flow sensor ( spirolog nor spirolife sensor ).

And here we all are ... still waiting, John.
