Abstract

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.

Claims

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.

2. The system as recited in claim 1, wherein the sensor comprises a pulse oximeter.

3. The system as recited in claim 1, wherein the second device comprises at least one of a base station monitor, a handheld monitor, or a smart phone monitor.

4. The system as recited in claim 1, wherein the sensor comprises a sensor configured to detect at least one of a presence or an absence of motion associated with the infant, and the transmitter is configured to transmit the at least one of the presence or the absence of motion associated with the infant.

5. The system as recited in claim 1, wherein the identifier is configured to provide an alert comprising at least one of an audible alarm, a visual alarm, a flashing display readout, an indicator light, a haptic feedback alarm, or an electronic message.

6. A method for monitoring an infant, comprising:

receiving, at a first monitoring device, an indication of an oxygen level of an infant and a heart rate of the infant, the infant'"'"'s oxygen level and the infant'"'"'s heart rate detected by a wearable device configured to be wearable by the infant at the infant'"'"'s foot;

measuring values for both the oxygen level and the heart rate of the infant, the values staying substantially constant during a first period of time to establish an oxygen level and a heart rate for the infant by a processor;

comparing, by the processor, 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;

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, and providing an alert when the oxygen level or the heart rate are not provided for a preprogrammed time period;

transmitting, from the first monitoring device, at least one of the infant'"'"'s detected oxygen level with the infant'"'"'s detected heart rate or the alert;

receiving, at a mobile monitoring device, at least one of the infant'"'"'s detected oxygen level with the infant'"'"'s detected heart rate or the alert from the first monitoring device; and

displaying, at the mobile monitoring device, the at least one of the infant'"'"'s detected oxygen level with the infant'"'"'s detected heart rate or the alert.

7. The method as recited in claim 6, further comprising receiving an indication of at least one of a presence or an absence of motion associated with the infant, and providing the alert when the infant'"'"'s detected heart rate is greater than the infant'"'"'s upper threshold heart rate and the at least one of the presence or the absence of motion associated with the infant indicates an absence of motion associated with the infant.

8. The method as recited in claim 7, wherein the indication of at least one of the presence or the absence of motion associated with the infant is received from the wearable device.

9. The method as recited in claim 6, further comprising receiving at least one of an indication of a room temperature, a light level, a noise, or a vibration from the wearable device.

10. A system for monitoring an infant, comprising:

a wearable device comprising a pulse oximeter configured to detect an oxygen level of an infant at the infant'"'"'s foot and a heart rate of the infant at the infant'"'"'s foot, 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;

a monitor 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 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 five percent (5%) or more of the established oxygen level, 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;
