Infant heart rate estimation based on non-contact UV photoplethysmography

Non-contact cardio signal monitoring is a requisite for premature infants, as adhesive sensors and electrodes such that an electrocardiogram can damage the epidermis. Many types of research on infants in newborn intensive care unit (NICU) are still their early stages with many challenges. Therefore, this study aims to use digital camera non-contact photoplethysmography imaging method measure compare heart rate from two experiments (without/with ultraviolet rays (UV)) inside unit. The UV) yielded promising results comparison reference measurements obtained ten infants. reveal robust correlation using pearson coefficients (PCC) 0.99 (for without 0.96 UV). Also, spearman coefficient (SCC) test 0.97 0.95 experiments, respectively Bland–Altman analysis revealed strong relationship between measured readings UV. experimental low error mean absolute (MAE), root squared (RMSE). work presents new aspect monitoring, showing performance upcoming medical applications.
