iSTAT ABGs and INR

Two topics that I probably should split.
We currently are using the iSTAT for Chem 8+ for after hour specimens or back up for general chemistry. We are very pleased with this test on iSTAT.
We are considering adding ABGs because our volume is extremely low and the desktop analyzers are all too expensive for us to continue using-entirely too much waste. Hopefully the cartridge expiration dates with iSTAT won't be too short. I am interested in what other users have to say about the iSTAT ABG.

How many iSTAT INR users are out there for monitoring coumarin therapy? Are you pleased?

We use iSTAT for PT/INR for Coumadin therapy monitoring and have been very pleased!
We also use iSTAT for most ABGs. We use G3+ and CG8+ cartridges and are also very pleased with them both.
Pulmonary obtains each patient’s initial gas using a Siemens RapidPoint and all other gasses are performed by iSTAT.

We used iSTAT for gases for years. Still use in OR for ABGs and ACTs. Went to EPOC for respiratory department 5 years ago. Better compliance with programing settings as it has drop down boxes and love the WiFi so docking is no longer an issue. However For low volume stick with the iSTAT. It is a great instrument. We have 22 iSTATs between OR, CT and cardiac units. We run HCG, CREA, CG8, ACTk.For respiratory we have 16 EPOCs.
iSTAT INR, used to use this but switched to CoaguSense about 7 years ago. LOVE this instrument. Look into it. We have in several Coumadin clinics, physician practices and our Home Health department has one per RN, about 30. Company is great to work with.
We use CG4 and CG8 cartridges and have not had any problems with them. The cartridges have a refrigerated shelf life of about 6 months.
Are you planning on having the samples brought to the lab and doing the testing there? We have used iSTAT as back up for blood gases in the past for things like short samples and it seems to work well. One consideration is the delay in testing. iSTAT policy says to test blood gases within 10 minutes. You could probably do a study to extend that, making it a LDT but if techs are running it anyway, not an issue. If your volumes are low, doing at the POC would be a big headache. Most of our expiration dates for plain G3 cartridges are 4-6 months. Ivy Douglas, OU Medical Systems, OKC, OK
Betty,
WE had a RapidPoint 500 installed in one of our small hospitals
because we have to standardized per corporate decision.
Before we got the RP500 they were using i-STAT for ABG.
After a year, we looked at the cost of maintaining the RP500, running QC, tech time.
And it was costing us a whole lot of money doing for 10-20 tests/month using RP 500
WE had to change measurement cartridge every 28 days whether we run 20 or 100.
There was a problem with having to prime the electrodes with whole blood 3 times
before running the patient or the pO2 were running low.
It is a great instrument for high volume facilities
WE decided to go back to using the i-STAT for ABG for that facility.
The ABG cartridges are good for 2 months ( not 14 days) after warming to room temperature.
