Pulse Oximeter for measuring saturation at home is usually inexpensive, so many experts consider its presence in a home first-aid kit to be mandatory.
However, it is not possible to make a diagnosis based just on pulse oximetry.
The measurement results make it clear about deviations from the norm. This information must be reported to the doctor who will be involved in the diagnosis and treatment of the patient.

As for Zacurate Pulse Oximeter, it can come in a variety of shapes, sizes, and appearances.
But the image on their screens is standardized and looks like this:
- At the top is an indicator of alarm, heart sounds, as well as the battery level;
- In the center is the saturation indicator and its limit value, as well as the pulse rate;
The bottom line contains the pulse wave graph. - These 2 models of the pulse oximeter are equipped with an audible signal, which is emitted when the saturation indicator goes out of acceptable limits.
This feature of these pulse oximeters will allow you not to constantly monitor the indicators on the screen, but to be guided by the monitor signal.
