1. A system for monitoring an infant, comprising:

  • a first device configured to be wearable by an infant at the infant'"'"'s foot, the wearable device comprising a sensor configured to detect an oxygen level of the infant and a heart rate of the infant, and a transmitter coupled with the sensor for transmitting an indication of the infant'"'"'s detected oxygen level and the infant'"'"'s detected heart rate;

    a second device comprising a receiver for receiving the indication of the infant'"'"'s detected oxygen level and the infant'"'"'s detected heart rate from the first device,a processor configured to establish an oxygen level and a heart rate for the infant by measuring values for both the oxygen level and the heart rate, the values staying substantially constant during a first period of time, the processor further configured for comparing the infant'"'"'s detected oxygen level and the infant'"'"'s detected heart rate to the established oxygen level and the established heart rate for the infant, the processor configured to compare the infant'"'"'s detected oxygen level to a lower threshold being a decrease of the established oxygen level of five percent (5%) or more, the processor configured to compare the infant'"'"'s detected heart rate to a lower threshold being a decrease of a percentage of the established heart rate and an upper threshold being an increase of a percentage of the established heart rate,an identifier for providing an alert when the infant'"'"'s detected oxygen level or the infant'"'"'s detected heart rate is outside the thresholds for either oxygen level or heart rate, the identifier providing an alert when the oxygen level or the heart rate are not provided for a preprogrammed time period, and a second transmitter for transmitting at least one of the indication of the infant'"'"'s detected oxygen level, the infant'"'"'s detected heart rate, or the alert; and

    a mobile monitoring device for receiving the at least one of the indication of the infant'"'"'s detected oxygen level, the infant'"'"'s detected heart rate, or the alert from the second device and displaying the at least one of the indication of the infant'"'"'s detected oxygen level, the infant'"'"'s detected heart rate, or the alert.
