Pulse Oximeter it is a non-invasive device that can be used to detect and monitor changes oxygen saturation level in the body. Pulse oximetry is widely used to monitor patients with respiratory diseases i cardiac-vascularand also during operation, intensive therapy i health monitoring at home.

Pulse oximeter for children
Pediatric pulse oximeters work in a similar way to adult pulse oximeters, but are adapted to smaller finger sizes and have additional features that make it easier to measure in children.
Children are often active and it is difficult to keep the finger immobile during the measurement. Therefore, it is worth choosing a pulse oximeter that is resistant to movement and provides accurate results even when the child twitches slightly or moves.
Infant Pulse Oximeter
Infant pulse oximeters are similar to pediatric pulse oximeters, but are typically even smaller in size to fit babies' little fingers perfectly.
An infant pulse oximeter should be able to accurately measure blood oxygen saturation levels even at low values. As this can be important in infants, select a model that provides high accuracy at low SpO2 levels.
Pulse oximeter how to read the results - Standard pulse oximeter
The two most important vital signs measured with a pulse oximeter are oxygen saturation and pulse. Each of them is appropriately marked on the pulse oximeter display.
One of the evaluated parameters is saturationwhich is oxygen saturation of the blood. Saturation is marked with a symbol They are 2 or SpO2 and is usually expressed as a percentage.
The result of blood oxygen saturation depends on age and additional factors:
-
In adults, it should be in the range of 95% - 99%.
-
In the case of the elderly, over 70 years of age and some people with certain chronic diseases, it should be in the range of 92 - 95%.
-
In patients during oxygen therapy, it should be in the range of 98% - 100%.
-
In cigarette smokers, it should be in the range of 92% - 95%.
The next parameter to be evaluated is pulse (puls). It is the number of heart beats per minute. The pulse is usually marked with a symbol PR bpm.
-
A normal heart rate should be between 60 and 100 beats per minute.
-
During pregnancy, the heart rate increases to 120 beats per minute.
-
During bradycardia, the heart rate is less than 60 beats per minute.
-
With tachycardia, the heart rate is greater than 100 beats per minute.
