One of the most important symptoms ofslotxoCOVID-19 patients is difficulty breathing. We can also check the oxygen in the blood as well. If the body has hypoxia in the blood than normal That means you are risking your life.
What is the blood oxygen value?
Our blood normally carries oxygen from the body that breathes oxygen into the lungs. The body needs enough oxygen to function normally in all systems and organs.
Risk factors for low blood oxygen levels have many causes, and they can range from diseases such as lung disease, bronchial disease, emphysema, heart disease, kidney disease, pneumonia, and obesity. and heavy smokers, etc.
low blood oxygen How dangerous is it?
If the body goes into hypoxia or hypoxia may occur in the blood. The body will try to balance. to keep oxygen levels from dropping This causes the body to breathe faster, faster and harder. The heart works harder to pump blood to the organs. make the heart beat faster This was followed by an increase in blood pressure from pumping more blood as well. There may be chaos, quarrels, confusion, or skin color, mouth color, a dark green look. There may be a drop in blood pressure. Problems with myocardial ischemia or blocked arteries in the body and if still unable to maintain the balance of oxygen in the blood to return to normal again The cells in the body begin to malfunction. and may cause various organ systems can start to fail
Blood oxygen, or blood oxygen concentration (Oxygen saturation), can be measured by the normal arterial oxygen saturation level in 95–100 percent of people. Below 90 percent may be at risk of hypoxia. May cause the body to be fatal.
What is the relationship between blood oxygen and COVID-19?
One of the most important symptoms of COVID-19 patients is difficulty breathing. We can also check the oxygen in the blood as well.
The oxygen concentration in the blood (Oxygen Saturation) can be measured using an instrument called a pulse oximeter, or a blood oxygen meter attached to a patient's finger. I will be able to tell the amount of oxygen in the body. This will help diagnose the patient's initial physical condition well. and more accurate The same is true for factor 5 of vital signs.
