The three common symptoms of COVID-19 are fever, cough, and shortness of breath. According to Professor Andrzej Fala from the Department of Lung Diseases and Internal Diseases of the Ministry of Interior and Administration, the latter symptom is the most dangerous and must not be ignored.
Dyspnoea with COVID-19
In the program “Get up and know” broadcast on TVN24, Professor Andrzej Fal from the Department of Lung Diseases and Internal Diseases at the Ministry of Interior and Administration, warned against the most dangerous symptom of COVID-19, namely dyspnea. “I would urge you to seek medical attention immediately if you have significant dyspnea, difficulty breathing,” he said.
The expert explained that most of the symptoms of the disease are repeated. Typical for COVID-19 are low-grade fever or fever, cough, and muscle and chest pain. Many people also complain of changes in taste and smell. However, according to the professor, breathlessness is the most dangerous.
– I would like to sensitize about one symptom, which is perhaps underestimated, because it sounds weirder. It’s about breathlessness. It is the patient’s subjective feeling that he is out of breath and he has worse breathing than yesterday. He also has rapid breathing and generally has trouble breathing, explains Professor Fal.

He added that like all other symptoms – cough and fever – can be treated at home, but if you are short of breath, seek medical attention as soon as possible.

Pulse oximeters for patients with mild COVID-19
According to the professor, the idea of using pulse oximeters to monitor the health of patients with mild COVID-19 symptoms who are recovering at home is a good solution.
Pulse oximeters allow you to monitor the saturation, i.e. the saturation of blood with oxygen. If the saturation drops below 94%, it means that the patient needs medical intervention. The device is easy to use. Professor Fal compares them to a pressure measuring apparatus. Many people have such equipment at home and use it regularly.
American doctors have noticed a worrying trend among patients infected with the SARS-CoV-2 coronavirus. Some of them experience the so-called hidden hypoxia, which is a form of hypoxia in the body. The condition develops in patients who have no other symptoms of the disease. Why is it dangerous?

A pulse oximeter works by measuring the absorption of radiation of two different lengths by red blood cells in capillaries. The signal measured by the device consists of two components – constant and variable. The variable describes the absorbance of pulsating arterial blood. Based on the measurement, the degree of oxygen saturation of the hemoglobin is calculated.

When the saturation decreases, we usually feel breathlessness (however, it is not always the result of a decrease in saturation). As already mentioned, this is a symptom that cannot be ignored.
