A blood analyzer is a vital part of the equipment needed by any hospital, clinic, or medical centre that deals with blood. When buying a machine, there are certain specifications that should be verified. Primarily, it should be able to measure blood gas and in addition be able to measure electrolytes such as, Na+, K+, Cl-, pH, pO2, pCO2, and Haematocrit.
It should have a sample temperature control of 37 degrees and offer input parameters for various details of the patient, including his or her temperature, haemoglobin F102, personal details, and anything else the machine needs to provide accurate readings.
Data from a blood analyser should be easily accessible and storable and it should preferably come with a built-in printer. A numeric keyboard is an important feature as is a graphic or LCD display and an RS 232 port.
The time taken to analyse the blood should be no more than 90 seconds and it should work on the whole blood sample, have a built-in syringe and capillary sampling. Cartridge systems tend to be less effective so should be avoided and the blood analysing system should be based on liquid/gas calibration technology.
The system needs to have an appropriate power input and at least a one-hour backup supply of power in case of power outage. In that event, the machine must be able to store and keep any information on it safely for the duration of the outage.
A blood analyzer will ideally come with a warranty that covers all parts for repair or replacement within a given time frame. It is also important that all safety standards are met in order to ensure safe usage for both staff and patients.
