Reference Value and Significance of MASIMO SpO2 Sensor

Reference value and significance It is generally believed that SpO2 normal should not be less than 94%, below 94% for lack of oxygen. Some scholars will SpO2lt; 90% as the standard hypoxemia, and that when the SpO2 is higher than 70% accuracy of up to 2%, SpO2 less than 70%, there may be errors. Clinically, we have a few cases of patients SpO2 values, and arterial oxygen saturation value comparison, that SpO2 readings reflect the patient's respiratory function, and to some extent, reflect changes in arterial oxygen. Thoracic surgery patients in addition to individual cases of clinical symptoms and numerical inconsistencies required for blood gas analysis, the routine application of pulse oximetry monitoring, clinical changes of the disease can provide meaningful indicators to avoid the patient repeated blood collection, but also reduce the nurses Workload.
