- Abstract:
- Within the last few years the use of Point-of-Care Analyzers increased. These testing is primarily performed in the emergency room, intensive care units, and in the operating room using small portable analyzers. The fact of being transportable and working with rechargeable or changable batteries and disposable cartridges caused us to use blood gas analysis in the prehospital setting. We tested three available blood gas analyzers: AVL OPTI 1, IRMA Blood Analyzer and the i-Stat Portlab System. All analyzers work with single-use cartridges and the calibration procedure is automatic. The AVL OPTI 1 uses a calibration gas and sucks in the blood by itself. The IRMA and the i-Stat system use a containing calibration gel, which must be removed from the sensory by injecting the blood sample. In all analyzers the results appear within 2-4 min on the screen. The OPTI 1 and the IRMA are able to print out the results automatically, the i-Stat uses an additional printer connected over an infrared adapter. During the observation period of 2 years more than 320 prehospital blood gas analyses were performed (200 with the OPTI 1.70 with IRMA and 50 with the i-Stat). All devices served their purpose. The main problems appeared with the application of the blood samples at the IRMA and the i-Stat. Because of this intricate procedures 21.4% and 20% of all tries failed. The time spent on the measurement was 2 to 5 minutes. All tested devices worked satisfactorily. Relating to the safety, the performance and the use the AVL OPTI 1 has to become the best notes. But this system is much more bigger and heavier than the others, especially the i-Stat Blood analyzer.
