Claim 10:
11. A method to upgrade operation of a patient monitoring device that is used in a caregiver environment, the patient monitoring device configured to communicate with a physiological sensor that senses light after it has passed through the tissue of a patient and generates a signal indicative of at least one physiological parameter of the patient in response to the sensed light associated with the patient, the patient monitoring device further configured to receive the signal and determine one or more measurements of the at least one physiological parameter of the patient from the received signal, the method comprising:
storing in memory comprising a data module the one or more measurements of the at least one physiological parameter, the memory further comprising at least a previous image module that has been tested and a latest image module, each of the latest and previous image modules comprising a system image that includes executable instructions to at least determine the one or more measurements of the at least one physiological parameter of the patient from the received signal;
determining a state of an override;
booting from the latest image module, wherein booting from the latest image module occurs during active monitoring when the override is enabled and occurs during a time of non-monitoring when the override is disabled.
