Pulse oximeters are essential medical monitoring devices used to measure the level of oxygen saturation in the blood along with the patient’s pulse rate. These devices provide quick and accurate readings by simply placing the sensor on a fingertip, making them convenient for both healthcare professionals and home users.

Pulse oximeters are widely used in hospitals, clinics, emergency care, and home healthcare settings to monitor patients with respiratory or cardiac conditions. Their portable design, easy operation, and reliable performance make them an important tool for continuous oxygen level monitoring and early detection of potential health issues.
