Pulse oximeter system
Pulse oximeter systems are described that detect an oxygen level of a user and/or monitor a user's heart rate. The pulse oximeter systems are configured to provide an alert when a user's detected oxygen level decreases below an established oxygen level, and/or when a user's heart rate decreases below a lower threshold value and/or increases above an upper threshold value. For example, an alert may be provided when a user's detected oxygen level decreases by more than about five percent (5%) of an established oxygen level. In some instances, an operator can set a level at which an alert will be provided.
1. A system for monitoring an infant, comprising:
a wearable device comprising: a pulse oximeter configured to detect an oxygen level and a heart rate of the infant when said pulse oximeter is affixed at the ankle or foot of the infant, and a transmitter coupled with the pulse oximeter for transmitting an indication of the infant's detected oxygen level and the infant's detected heart rate; and
a device comprising a receiver for receiving the indication of the infant's detected oxygen level and the infant's detected heart rate from the wearable device,
a processor configured with, a preset, predetermined oxygen level or to establish a set oxygen level output; and
said processor configured with, a preset, predetermined heart rate or to establish a set heart rate, and said processor configured to measure values for both the oxygen level and heart rate;
the processor further configured for comparing the infant's detected oxygen level and the infant's detected heart rate to at least one of the predetermined oxygen level or the established set oxygen level and to at least one of the predetermined or the established set heart rate of the infant,
wherein the predetermined oxygen level or the established set oxygen level has an upper threshold and at least one lower threshold, and
wherein the at least one lower threshold of the predetermined oxygen level or the established set oxygen level is at least a 5% decrease from the upper threshold of the predetermined oxygen level or the established set oxygen level,
wherein the predetermined heart rate or the established set heart rate has an upper threshold and a lower threshold,
an identifier for providing an alert when:
the infant's detected oxygen level is outside the at least one lower threshold of the predetermined oxygen level or the established set oxygen level,
the infant's detected heart rate is outside the upper threshold of the predetermined heart rate or the established set heart rate, or
the infant's detected heart rate is outside the lower threshold of the predetermined heart rate or the established set heart rate and the infant's detected oxygen level is outside the at least one lower threshold of the predetermined oxygen level or the established set oxygen level;
a second transmitter for transmitting to a mobile monitoring device at least one of: the indication of the infant's detected oxygen level, the indication of the infant's detected heart rate, or the alert, and displaying at the mobile monitoring device at least one of: the indication of the infant's detected oxygen level, the indication of the infant's detected heart rate, or the alert;
wherein the identifier provides an alert when the receiver stops receiving, after the preprogrammed period of time, the indication of the infant's detected oxygen level and infant's detected heart rate.
2. The system of claim 1 , wherein the alert includes at least one member of a group consisting of: an audible alarm, an indicator light, a display readout, haptic feedback, and an electronic message.
3. The system of claim 1 , wherein the wearable device further includes a device for detecting motion.
