1. A patient monitoring device configured to be removably secured to a patient, the patient monitoring device comprising:
a physiological sensor configured to be removably coupled to a finger of the patient;
a cable comprising a first end coupled to the physiological sensor and a second end opposite the first end;
a strap configured to secure to a wrist of the patient;
a base coupled to the strap, the base comprising:
a first side, a second side opposite the first side, a third side, a fourth side opposite the third side, a bottom surface positioned adjacent said strap and configured to face toward the patient's wrist, and a top surface configured to face away from the patient's wrist, wherein the first side is positioned closer to the patient's finger than the second side when the base and strap are secured to the patient's wrist, and wherein the second end of the cable is integrally formed with and extends outward from the second side of the base;
one or more electrical contacts operably positioned by or near the top surface of the base; and
a cable retainer arranged along the third side of the base and configured to at least partially surround and secure a portion of the cable; and
a monitor instrument configured to removably couple to the base and receive one or more signals from the physiological sensor via the base;
wherein, when the monitor instrument is coupled to the base, the strap and base are secured to the patient's wrist, the cable is secured within the cable retainer, and the physiological sensor is coupled to the patient's finger, the cable: extends away from the second side towards an elbow of the patient; loops 180 degrees towards the patient's finger; and extends to the physiological sensor coupled to the patient's finger.
