preguntas frecuentes Oximetro Longfit Care

What does the oximeter measure and what do the measurements mean?

A pulse oximeter is a device that is used to measure oxygen saturation in the blood. The oximeter actually measures the percentage of haemoglobin in the oxyhaemoglobin and when this concentration is between 95% and 99%, you are considered as not having pulmonary problems.


Oxygen saturation (SpO2) measures the amount of oxygen carried in the blood in relation to its total capacity. In other words, it is an estimate of how much oxygen is contained in the blood’s haemoglobin in comparison to the amount it could contain.

Charge the smartwatch in a USB charging port.

When charging the smartwatch in a USB charging port or computer with USB, make sure to connect it so that the smartwatch screen is visible.

When it starts to charge, the screen lights up displaying the word “Charging” and the symbol of the current battery capacity, and, five seconds later, the screen switches itself off until the charge is complete. The screen will then light up again and indicate that the charge has been successfully completed.

We have observed that in some (wide) USB charging ports it does not charge properly, due to the fact that a proper charging connection has not been established.

If such is the case, first check to see that the direction and position are correct. Otherwise, try another charging port or computer with USB. This is a residual problem which occurs in just a few charging devices.
