A shocking claim has emerged over the fight against the corona virus epidemic and pulse oximeters, an essential tool for healthcare workers. Pulse oximeters are used to detect oxygen levels in the body. In Delhi, the Kejriwal-led Aam Aadmi Party government had made Corona patients available at home to check oxygen levels. The government distributed thousands of oximeters to corona patients. But now the claim that has come out will surprise everyone and this claim has been made by America.

According to the US Food and Drugs Administration, a light device to monitor oxygen levels in the blood can cause problems for dark skin people. The US Department has claimed that oximeters may give incorrect results when measuring oxygen levels of people with dark skin. However, the US federal agency said on Friday that the oximeter is useful for the measurement of oxygen in the blood. Pulse oximeters have some limitations and it can also be risky in some circumstances.

The federal agency said that it has been revealed that several factors may affect the accuracy of oximeter reading. Including skin pigmentation, skin thickness, skin temperature, tobacco use and even nail poses. The FDA said in one of its statements that patients such as the corona virus who are monitoring their condition at home should pay attention to all signs and symptoms of their condition and talk if there is any discomfort.

The agency recommends that patients need to pay attention to the color of their face, lips or nails, shortness of breath, chest pain, and pulse rate. Engesi further noted that some patients with low oxygen levels do not show all of these symptoms. In such a situation, only a doctor can identify it.
