An oximeter, or a pulse oximeter, is a medical device that measures the amount of oxygen in the blood. A pulse oximeter has become an important monitoring tool in modern medicine. The oximeter is attached to a monitor so as to enable a direct reading of the patients oxygenation at all times. This is because timely recognition of low saturation conditions and emergency correction measures can prevent potentially devastating complications. Before the oximeter was invented, a series of complicated blood tests were needed.
Oximeter manufacturers have been rising to the occasion by continually improving on their products to reduce the margin of error and provide safer tools. Clinicians are thus provided with the most technologically advanced systems. Oximeters now come in a variety of shapes and sizes, and they serve a variety of uses, but the main aim of all oximeters is to monitor oxygen saturation readings.
Clinical motion by the patient and corresponding errors in reading accurate saturation levels pose a major challenge to manufacturers. Clinical motion may cause volatility, dashing of display, inaccuracy, and freezing of saturation readings. Studies reveal that...
