Before the arrival of the second wave of infections by COVID-19, the infectologist of the National Institute of Health (INS), Manuel Espinoza, indicated that it is important that families have the pulse oximeter or oximeter in their homes, which is a doctor who monitors the level of oxygen concentration that we have in the blood in a non-intrusive way.
In dialogue with this medium, the specialist Espinoza pointed out that this device is important to constantly monitor a person who is already sick with COVID-19 to prevent his respiratory system from worsening.
“The use is for sick with COVID-19, to monitor sick people if it is getting worse or not, at least from a respiratory point of view. The pulse oximeter gives you two measurements, one which is the oxygen saturation that helps to know how people are breathing and the other is the heart rate”, He declared to this medium.
“If the oxygen saturation is low and despite this the person feels well, they should still ask for medical support, when it is below 95% people should be concerned and should be evaluated, and when it is 92% the family member already requires oxygen “Espinoza stressed.
What is the range of the oxygen saturation?
According to the doctor, a healthy person who does not have any pathology should have a blood oxygen level between 95-100%. When the range drops to 94% or less than 93%, this is an indication that something is happening in our body and we must go immediately to a medical center.
“On the coast of Peru, the normal is 95% to 100%, when it is less, something is happening, if it comes out less 93%, perhaps 92%, that person has to go to a hospital because they need oxygen”, He indicated.
“The values in the mountains and in the jungle are lower because at higher altitudes there is less oxygen, for example, at 3,000 meters above sea level in Jauja or Huancayo, the normal saturation range is 92% to 98%, at 4 thousand meters high as Cerro de Pasco the normal is 88% to 95%. For each place there are different levels of normality, that is why this device becomes a great help “, stressed the specialist.
How to use?
The infectologist Manuel Espinoza explained that the pulse oximeter has an internal sensor that helps to measure the oxygen saturation in the blood and the heart rate. In that sense, this element is put on the index finger of the hand.
“It has like a light and this device is to be put on the fingers, the person who is going to measure the saturation must be at rest for at least 5 minutes and must be sitting or lying in bed”, He indicated.
In addition, he specified that the nails must be clean, without enamels and the fingers must be warm. “The hand should not be moving, the finger should not be cold because it can give you a wrong value. Through the curves that appear, you will see the terms that have to be written down in a notebook”, He detailed.
Finally, he maintained that the frequency of its use should be every four to six hours. “If the person is stable, it would be three times a day, but if we notice that he is already having a fever, then he should be monitored every hour to see if it is necessary to see a doctor”, Culminated.
