5 things to know about Pulse Oximeter. What is a pulse oximeter? A pulse oximeter is a device that is used to measure oxygen saturation levels (SPO2 levels) / oxygen levels in the blood. The pulse oximeter gives out two readings which are oxygen levels and pulse rate. What happens when oxygen levels drop below the normal oxygen level in the body? It is very important for the oxygen levels in the body to be in the normal range. The proper functioning of the body depends on oxygen which is carried by the blood to all the cells in the body. When the oxygen levels in the body drop, the functioning of various organs like the brain, heart, and kidneys can get affected. The condition of low oxygen levels in the body is called hypoxemia. Importance of fingertip pulse oximeter in the times of COVID-19 According to medical experts, low oxygen levels are registered in coronavirus patients. So, it is important to monitor the oxygen levels in the blood to detect covid pneumonia in the early stage. COVID pneumonia is a deadly condition seen in severe covid cases. But a pulse oximeter cannot be trusted solely to detect coronavirus. Low oxygen levels can be a symptom of various other conditions as well. What is the normal oxygen level reading? You can find the normal pulse oxygen level readings here 0:49​​ When the oxygen levels drop below the ideal oxygen level readings, it is a cue to consult a doctor.
