Version 2.4 Minor change to notes feature/parameter section. Temporarily removed due to issues on certain devices. About the Blood Gas Handbook: Blood gas status plays a key role in evaluating the condition of critically ill patients. Evaluation of blood gas parameters can be divided into subgroups of oxygen status, related metabolic parameters and acid-base status. Because each subgroup consists of several parameters, the amount of data to interpret may be overwhelming. Radiometer’s blood gas handbook app is an easy-to-use guide to assist you with this task. The app supports the following languages: Danish, English, French, German, Japanese, Portuguese and Spanish. The app opens in default language chosen on your device. Specific choice of language can be made through the app's settings section (settings section added in version 2.2) or changing the region settings on the device. Interactive features: The app offers guidance to the evaluation of arterial oxygen status based on comprehensive blood gas analysis (including oximetry) and a closely related metabolic parameter, lactate. Users can add and edit their own reference intervals as well as notes for individual parameters. In addition, Radiometer’s new app provides a description of the parameters available on Radiometer‘s blood gas analyzers, including blood gas and acid-base parameters, metabolic parameters and electrolytes, as well as guides to evaluating them. Although such a guide always has to be used with caution, as not every possible detail or condition can be covered, it can help the clinician make decisions with regard to the need for further tests and therapeutic interventions.
