Oxygen saturation (SpO2) is an essential parameter that helps define the amount of oxygen in the blood and its delivery throughout the body. A healthy individual’s normal SpO2 level should be between 97% to 99%. When the level of oxygen in the blood is low, especially found in the feet and legs, can lead to reduced mobility, stiffness of joints, muscle pain, and wounds that are harder to heal. Besides, research shows that COVID-19 patients can experience silent hypoxia, whereby they have low oxygen levels without any initial warning signs. These patients are at an increased risk of sudden deterioration in their condition.FunctionTo monitor patient’s health status by measuring the blood oxygen saturation (SpO2, 70~99%) and pulse rate (PR, 20~250bpm)AdvantagesPainless and non-invasiveSingle button operation, easy to use2-colour OLED display, real time graphical display of pulse (bar graph and wave form)Auto sleep mode and switch offSmall and compact, allow you to take measurement anytime anywhereAble to operate at a humidity level up to 95%, suitable for Hong Kong weather conditionsWho needs thisMuscle pain, stiffness, or weaknessNumbness or cramping in the legsDiabetic footElderlyDifficult breathing
