Fighting Against the Coronavirus Leadtek Oximeter Assists Early Self-Diagnosis

With the ongoing pandemic of the COVID-19, the recent report from WHO emphasizes that "Oxygen therapy is the major treatment intervention for patients with severe COVID-19", "All countries should make the best use of pulse oximeters and medical oxygen systems to treat the patients.” In the WHO's manifestations classification of the coronavirus disease, it is further mentioned that under the room air environment, an adolescent or adult with SpO2 reading <93% or children with SpO2 reading<90% are recommended to seek medical attention immediately.

Blood oxygen saturation (SpO2) is one of the important indicators of the severity of coronavirus. It can monitor the oxygen concentration in the blood of a patient and alert a medical caretaker when the oxygen level falls below the acceptable limits for fast response. These devices are necessary tools in situations where a patient's blood oxygen saturation needs to be monitored. If you have symptoms of dyspnea, fast breathing, and hypoxemia that are commonly seen on early stages of coronavirus patients, it is recommended to see a health professional and conduct home self-monitoring.

The fingertip pulse oximeter introduced by Leadtek uses a lightweight and non-invasive design to detect the oxygen saturation in human blood. Using optical technology, it absorbs red light and infrared light through the perfused tissue to quickly obtain accurate blood oxygen saturation (SpO2). The built-in anti-motion algorithm can still maintain the accuracy of measurement data in emergency situations. It is convenient for people to monitor blood oxygen level anytime and anywhere, whether it is the diagnosis in the medical institution or the personal home monitoring.

The fourth edition of the Novel Coronavirus Pneumonia Diagnosis and Treatment Plan also mentioned that further clinical classifications will be made. Based on whether there are clinical symptoms, whether there is lung inflammation, the severity of lung inflammation, whether there is respiratory failure, shock, or organs failure, the classifications include regular form (fever, respiratory tract symptoms, imaging shows visible lung inflammation), severe form (shortness of breath, RR≥30 breath / min, oxygen saturation < 93% at rest condition, arterial oxygen partial pressure (PaO2)/ fraction of inspired oxygen (FiO2) < 300mmHg), and critical form (respiratory failure occurs and mechanical ventilator is required, shock, combined failure of other organs that requires ICU monitoring). Therefore, the monitoring of blood oxygen saturation is very important to preventing and controlling of the coronavirus. It is recommended to keep an oximeter at hand to monitor and care for your lung health at all times.
