We need to purchase a new blood gas machine as the one we currently have in use (Radiometer Copenhagen) becomes more and more unreliable. Which machines do people use in their units and what advantages/disadvantages do this machines have?

Thanks!

i would prefer Roche company (very accurate and measure all parameters?

The question to answer is --- What are you expecting from the machine?

Do you just want pH, PCO2 ?

Are do you also want MetHb? --- this is very important if you use inhaled Nitric Oxide in your unit

Also do you want Hb , electrolytes ?

The most important is how is the after sales maintenance and availability of the buffer solutions//calibrating gases/ cleaning solutions?

I would not recommend any single company, because that would be biased. All the ones out there, with quality accreditation and international presence have excellent products. The product which you will buy will be based on your requirements, the ease of use and maintenance. It is also a good practice to inquire with your colleagues in hospitals nearby to their experience with their blood gas machines and any complaints that they have. Some companies have excellent after sales service in some areas but weak in others. As blood gas machines require constant servicing and constant care, I strongly recommend a company which has a strong presence in your area and also has a good reputation in your locality.

Hope that helps !

in our level2 unit we use ISTAT from Abbott (http://www.abbottpointofcare.com/)

Works well for level2 requirements.

For more heavy use, I'd advice that a more stationary machine.

Good points by @JACK, a good service programme is essential for a stationary machine used heavily.
