They use red light (660 nm) and infrared light (910 nm) transmitted to the capillaries of the finger to calculate the amount of light reflected in the blood. When measuring blood oxygen, the difference between reduced haemoglobin and oxygenated haemoglobin is the most basic data for measuring blood oxygen saturation (SpO2) by detecting the difference between the two kinds of light absorption at different wavelengths.<\/p><p class=\"mh-text\">Haemoglobin concentration and oxygen saturation are calculated by measuring the density of light transmission in the tissue.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f68e4b0 elementor-widget elementor-widget-image\" data-id=\"f68e4b0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"1642\" height=\"640\" src=\"https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4.png\" class=\"attachment-full size-full wp-image-54935\" alt=\"\" srcset=\"https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4.png 1642w, https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4-300x117.png 300w, https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4-1024x399.png 1024w, https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4-768x299.png 768w, https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4-1536x599.png 1536w, https:\/\/medisana.asia\/my\/wp-content\/uploads\/sites\/3\/2026\/08\/Health-Knowhow_PulseOximeter_4-450x175.png 450w\" sizes=\"(max-width: 1642px) 100vw, 1642px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d6a9e01 e-con-full e-flex e-con e-parent\" data-id=\"d6a9e01\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-da8d802 elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"da8d802\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">What is the pulse rate?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4afe335 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"4afe335\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p class=\"mh-text\">Pulse rate is the number of pulse beats per minute, with the pulse referring to beats of the superficial artery.
