AbstractPurpose -An arterial blood gas (ABG) interpretation remains indispensable tool to assess and monitor critically ill patients in the intensive care unit or other critical care settings. This paper proposes a mobile-based interpreter for ABG tests with the aim of providing accurate diagnosis in face of multiple acid-base and oxygenation disorders. The paper aims to discuss these issues. Design/methodology/approach -A rule-based expert system is designed and implemented using interpretation knowledge gathered from specialist physicians and peer-reviewed medical literature. The gathered knowledge of ABG tests are organized into premise-explanation pairs to deliver reliable evaluation with the appropriate differential in a timely manner. Findings -Performance of the developed interpreter prototype was assessed using a dataset of 74 ABG tests gathered from medical literature and clinical practice. The obtained results demonstrated that the identified acid-base and oxygenation disorders and their differential diagnoses are accurately correlated with those assessed manually by consultant specialist physicians. Research limitations/implications -This application is foreseen to be an everyday tool for clinicians at various levels; however, further studies are needed to evaluate its eventual impact on patients' outcomes. Originality/value -The contribution of this paper is the development of a new ABG interpreter which combines both the acid-base and oxygenation disorders in a single application. Unlike existing ABG interpreters, it is comprehensive and capable of accurately identifying all kinds of acid-base disorders and their combinations. In addition, it utilizes urine electrolytes which are useful tools in the differential diagnosis of normal anion gap metabolic acidosis and metabolic alkalosis. The interpretation algorithm is also designed to be flexible for some clinical settings which lack some input test data.

A Methodology Based on Expert Systems for the Early Detection and Prevention of Hypoxemic Clinical Cases

“…With regard to the advances in the use of oxygen measurement devices or pulse-oximeters, several studies and approaches [ 12 , 40 , 41 , 42 , 43 , 44 ] highlight the different criteria for their placement and the interpretation of the results obtained. As for the second research line mentioned, all the reviewed works [ 45 , 46 , 47 , 48 , 49 , 50 , 51 ] have been already described in Section 1.4.2 . Generally, all of them propose systems that, starting with the pulse-oximeter readings, implement predictive solutions based on different technical approaches.…”

“…Even if at that moment the results were not satisfactory enough, as the accuracy obtained was low, the authors concluded that the bagged complex trees approach used resulted to be the best one. Lastly, it is also of interest to mention the work by Al-Taee et al [ 51 ], in which a tool for mobile devices is proposed that allows to provide help in the making of decisions associated to the interpretation of gasometry results.…”

Diseño de una aplicación móvil para la interpretación de gases arterio-venosos.

“…Diversos autores de manera previa han optado por la creación de herramientas tecnológicas para facilitar la interpretación de los trastornos en mención con el objetivo de disminuir las repercusiones que pueden traer al paciente, en el año 2013 Taee et al [17] miembros de la escuela de computación y sistema de la información de la Universidad de Kingston ( Reino Unido) conscientes de que los gases son una herramienta indispensable para evaluar y monitorear pacientes críticamente enfermos diseñaron un prototipo para la identificaron del desequilibrio ácido -base y de oxigenación, dicho prototipo fue puesto a prueba a partir de 74 muestras de gases en sangre extraída de la literatura médica y la práctica clínica. Los resultados mostraron que Universidad de Manizales -Facultad de Ciencias de la Salud los trastornos evidenciados por esta aplicación correspondían a los calculados por los pares.…”

Impact of Computerized Prescription on Medication Errors and Workflow Efficiency in Neonatal Intensive Care Units: A Quasi-Experimental Three-Phase Study

“…Such a problem can be minimized or prevented through utilizing computerized medication prescription approaches with a clinical decision support system (CDS) [12][13][14][15] and electronic medical records. These technology-based approaches and many others have been proven to be important in various health care aspects including diagnoses and CDS, 15 remote patient monitoring, 16 as well as improving workflow efficiency. 17 Implementation of a computerized physician order entry (CPOE) system with CDS has been shown to reduce various medication prescription errors, such as dispensing inaccuracies and drug choice errors.…”
