User Manual for Handheld Pulse Oximeter II Common Knowledge 1 Meaning of SpO2 SpO2 is the saturation percentage of oxygen in the blood, so called O2 concentration in the blood; it is defined by the percentage of oxyhemoglobin (HbO2) in the total hemoglobin of the arterial blood.
User Manual for Handheld Pulse Oximeter dysfunctional hemoglobin, such as carboxyhemoglobin or metahemoglobin. 3 Normal SpO2 Range and Default Low Limit In campagna area, healthy people’s SpO2 value is greater than 94%, so the values below 94% are determined as hypoxia. SpO2<90% is considered as the default threshold for determining anoxia by most researchers, so SpO2 low limit of the oximeter is set as 90% generally.
User Manual for Handheld Pulse Oximeter 5 Factors causing low SpO2 value (pathology reason) Hypoxemia disease, functional lack of HbO2 Pigmentation or abnormal oxyhemoglobin level Abnormal oxyhemoglobin variation Methemoglobin disease Sulfhemoglobinemia or arterial occlusion exists near sensor Obvious venous pulsations Peripheral arterial pulsation becomes weak Peripheral blood supply is not enough 47
