Objective : This study was conducted in order to determine the usefulness of the application of home patient care using a portable critical care analyser (OPTI‐C) after the precision of the OPTI‐C was examined. Methodology : The OPTI‐C, which measures sodium (Na + ) and potassium (K + ) as well as pH, P CO 2 and P O 2 in whole blood, was used. In order to confirm the linearity of the OPTI‐C, analysis using reference materials was performed ( n = 81). Correlation testing with whole blood samples from patients was also performed using other analysers in the laboratory ( n = 108). Home patient testing was performed with 15 patients. Results : The slope linearity and correlation coefficients were as follows: pH, 1.0174 ± 0.0091, 0.99972; P CO 2 , 0.9681 ± 0.0094, 0.99967; P O 2 , 0.9844 ± 0.0085, 0.99974; Na ST , 0.9788 ± 0.0115, 0.99911 and K ST 0.9964 ± 0.0128, 0.99893. The equivalent results from other analysers showed pH, 1.071 ± 0.009, 0.9963; P CO 2 0.985 ± 0.016, 0.9870; P O 2 0.989 ± 0.007, 0.9976; Na + , 1.075 ± 0.278, 0.9662 and K + 1.120 ± 0.020, 0.9842. The correlation coefficients and P values were as follows: pH, 0.9790, P > 0.1; P CO 2 , 0.9990, P > 0.1; P O 2 , 0.9980, P > 0.1; Na + , 0.9438, P > 0.05, and K + , 0.9174, P > 0.1. Conclusion : The use of portable critical care analysers for near patient testing for home‐care patients is recommended in order to increase the efficiency of visits as well as to improve the quality of patient care.
