Abstract
Objective
In this study, we aimed to evaluate the accuracy of HR and SaO2 data obtained using a smartphone compared with the measurements of a vital signs
monitor (VSM) and an arterial blood gas (ABG) device, respectively.
Material and methods
In this single-center prospective study, the HR and SaO2 measurements were performed using the built-in sensor and light source of a Samsung
Galaxy S8 smartphone and compared to the results of VSM and ABG device. The Bland-Altman
analysis was used to evaluate and visualize the agreement between the methods.
Results
The data of 101 patients were analyzed. There was a high correlation between HR measured
by smartphone and HR measured by VSM [P < 0.0001; 0.9918 (95% CI = 0.987–0.994)].
In addition, the SaO2 values obtained by smartphone were highly correlated with those by ABG (P < 0.0001;
0.968 (95% CI = 0.952–0.978)).
Conclusion
The HR and SaO2 values obtained by smartphone were found to be consistent with the measurements of
the reference devices. With the growing use of smartphone technology in the health
field, we foresee that patients will be able to make their own triage assessment before
presenting to the hospital.
