Abstract: A patient monitor in communication with ECG leads is configured to monitor physiological parameters over time to indicate an abnormal condition. The physiological parameters can include an ST parameter and/or action potential, and the abnormal condition can be an anaerobic state. To identify the abnormal condition, the patient monitor identifies a reference physiological parameter measurement of a patient at a first time and determines expected physiological parameter measurements based on different heart rates. The patient monitor compares an expected physiological parameter measurement of a patient at a current heart rate with an actual physiological parameter measurement at the current heart rate. The patient monitor indicates an abnormal condition if the difference between the expected and actual physiological parameter measurement is greater than a threshold amount.

Abstract: The present disclosure relates to determining an physical state of a moving vehicle operator. In an embodiment, if it is determined that a vehicle operator is impaired, the vehicle is programed to automatically and safely stop a vehicle before an accident occurs. In an embodiment physiological sensors in the seat, steering wheel, or wireless sensors placed on the vehicle operator's body are used to determine an impairment state of a vehicle operator.

Abstract: Disclosed is the selecting of a limit value, such as an alarm limit, from a range of limit values dependent on a starting value. The selected limit value is applicable e.g. in a patient monitoring system for monitoring a physiological parameter for providing a signal when a monitored value of the physiological parameter exceeds the selected limit value. According to the invention, the range of limit values comprises a functional range with a functional relationship of the limit values to the starting values, and at least one non-functional range with no functional relationship of the limit values to the starting values.
