Embodiments of the present disclosure include a handheld multi-parameter patient monitor capable of determining multiple physiological parameters from the output of a light sensitive detector capable of detecting light attenuated by body tissue. For example, in an embodiment, the monitor is capable of advantageously and accurately displaying one or more of pulse rate, plethysmograph data, perfusion quality, signal confidence, and values of blood constituents in body tissue, including for example, arterial carbon monoxide saturation ('HbCO'), methemoglobin saturation ('HbMet'), total hemoglobin (&#x201c;Hbt&#x201d;), arterial oxygen saturation (&#x201c;SpO&#x201d;), fractional arterial oxygen saturation (&#x201c;SpaO&#x201d;), or the like. The monitor can determine which a plurality of light emitting sources and which of a plurality of parameters to measure based on the signal quality and resources available.

In an embodiment, the monitor advantageously includes a plurality of display modes enabling more parameter data to be displayed than the available physical display real estate.

Embodiments of the present disclosure includes a portable pulse oximeter, such as a handheld pulse oximeter, that provides a user with intuitive key navigation for device operation, which reduces an amount of visual concentration needed to handle and operate the oximeter. In various embodiments, the portable pulse oximeter includes one or more of user input keys disposed along curve, an alignment edge providing guidance by feel of a user's digits to the input keys, raised convex keys also providing navigation by feel, a protective boot disposed around various portions of the oximeter housing to protect against impacts, a table-top stand, combinations of the same, or the like.
