Abstract
An arm mountable portable patient monitoring device configured for both on patient monitoring of parameter measurements using one or more sensors operatively connected to the portable patient monitoring device and wireless transmission of parameter measurements. The arm mountable portable patient monitoring device includes a pulse oximetry sensor configured to be wrapped around a digit of a patient, a housing having a size and shape configured for mounting to a lower arm of the patient, and a strap mountable to the back side of the housing and configured to secure the housing to the lower arm of the patient. The housing includes a display, a first sensor port positioned on the housing to face toward a hand of the patient, second and third sensor ports, a battery, signal processing arrangements to cause display of parameter measurements, and a transmitter to transmit information indicative of the measurements.
