1. A pulse oximetry system configured to secure to a wrist and measure a blood oxygen saturation at a tissue site on a pinky finger of a subject, the pulse oximetry system comprising:
a sensor dock assembly comprising:
a dock and a strap configured to secure the dock to the subject's wrist;
a ring member configured to secure around a first portion of the subject's pinky finger;
one or more emitters operably positioned by a first portion of the ring member, the one or more emitters configured to emit optical radiation into tissue of the subject's pinky finger;
one or more detectors operably positioned by a second portion of the ring member that is opposite the first portion of the ring member, the one or more detectors configured to detect at least a portion of the optical radiation emitted from the one or more emitters after passing through said tissue and output at least one signal responsive to the detected optical radiation;
a cable connected to and extending from the dock and in electrical communication with the one or more emitters and the one or more detectors, the cable configured to transmit said at least one signal outputted by the one or more detectors to the dock;
a first cable retainer disposed on the strap or the dock, the first cable retainer comprising a prong configured to secure a first portion of the cable;
a second cable retainer configured to secure around a second portion of the subject's pinky finger between the ring member and the subject's palm, the second cable retainer comprising a prong configured to secure a second portion of the cable;
wherein the first and second cable retainers are configured to allow the cable to be positioned along an outside edge of a palm of the subject and along at least a portion of an outside edge of the subject's pinky finger when the ring member is secured to the first portion of the subject's pinky finger and the dock is secured to the subject's wrist; and
a sensor hub configured to releasably connect to the dock, the sensor hub comprising one or more hardware processors and a battery;
wherein, when the sensor hub is connected to the dock of the sensor dock assembly:
the sensor dock assembly is configured to receive power from the battery of the sensor hub; and
the one or more hardware processors of the sensor hub are configured to receive and process said at least one signal outputted by the one or more detectors of the sensor dock assembly to determine at least one physiological parameter of the subject.
