PERSONALIZED VITAL SIGN MONITORS

Systems, methods, and devices relate to monitoring biological conditions (e.g., vital signs) using patient-specific ranges. An example method includes receiving, from a sensor, first measurements of a vital sign of an individual determined automatically during a first time period and determining a baseline of the vital sign based on the first measurements by averaging the first measurements. A threshold of the vital sign can be a predetermined percentage of the baseline. Second measurements of the vital sign can be received from the sensor. In response to determining that at least one of the second measurements is outside of the range, an alarm may be triggered.
