In smaller establishments, there may not be the availability of ‘clinical’ analysers.
If the local analyser is broken, the lab should be able to offer at least a minimal service as backup.
One should also consider the cross-infection risk of carrying “dirty” A&E samples into a pristine clean ITU or SCBU environment.
Our ITU and SCBU will not allow any outsiders into their departments’ analysers, and outsiders do not have user access codes.
Most of us now have air tubes and a small study we did between lab (via tube) and ITU only showed discrepancy in pO2 if
there was any sign of a bubble in the sample.
We have 5 machines outposted, but the folks on ITU and SCBU pulled the cross-infection card when in-comers kept blocking their machines, particularly SCBU
and foetal scalp samples when maternity was already blocked with foetal scalp.
A&E followed suit after malfunction of their analyser after visits from in-comers.
An analyser in the laboratory at least means there is always one working in the hospital.
There are publications identifying blood gas analysers as a residual source of infection. (Thank you Google)

Subject: Re: Blood gas acceptance criteria
What are the reasons (organisational or other) for having a blood gas analyser in the laboratory rather than in a clinical area? Are there any advantages?

Hi collective brain,
What criteria do people use to accept or reject samples for blood gas analysis?
Are criteria such as
1) analysis
within 30 minutes of collection
2) absence
of any air bubbles
3) rejecting
samples sent to the lab by pneumatic tube systems (or not reporting PaO2)
strictly adhered to?
Many thanks in advance for responses – I will collate and repost.
