Abstract

A handheld device includes a contact surface, an optical module, a processor, a display module, and a user operable switch. The optical module is disposed on the contact surface. The optical module has at least one optical emitter and at least one optical detector. The at least one optical detector has a light shield associated with the contact surface. The light shield is configured to exclude ambient light from the contact surface when the contact surface abuts tissue of a patient. The processor is coupled to the optical module and configured to execute instructions for determining a measure of oximetry corresponding to the tissue. The display module is coupled to the processor and is configured to indicate the measure of oximetry. The user operable switch is configured to activate at least one of the processor, the optical module, and the display module.
