Pulse Oximeter

Pulse Oximetry is often referred to as the fifth vital sign. A pulse oximeter is useful in any setting where a patient's oxygenation is unstable, including intensive care, operating, recovery, emergency and hospital ward settings, pilots in unpressurized aircraft, for assessment of any patient's oxygenation, and determining the effectiveness of or need for supplemental oxygen. Assessing a patient's need for oxygen is the most essential element to life; no human life thrives in the absence of oxygen.

In the design, the importance of its function was not to be downplayed. The fact that monitored signal bounces in time with the heart beat, gave us a useful metaphor for designing the soft but firm rubber, with every rib resembling a pulse. The main body follows styles of consumer electronic devices, as the oximeter can also be used in sports.
