WHAT IS CLAIMED IS:

1. A system for monitoring a respiratory rate, comprising:

an accelerometer configured to measure, in real time, movement of a diaphragm by detecting tilts of the accelerometer;

a processor connected to the accelerometer and configured to:

process and filter signals associated with measurements from the accelerometer;

compute the respiratory rate based on filtered signals; and

convert the computed respiratory rate to a digital readout to output the digital readout on a display; and

a casing enclosing the accelerometer and processor to provide shock mitigation.

2. The system of claim 1, wherein the casing enclosing the accelerometer and the processor is configured to be attached directly to a patient's abdomen using a removable adhesive.

3. The system of claim 1, wherein the casing enclosing the accelerometer and the processor is attached to a clothing of a patient for indirect contact with the abdomen.

4. The system of claim 3, wherein the casing enclosing the accelerometer and the processor is attached to the clothing using a clip, a magnet, an adhesive, or other fastening mechanism.

5. The system of claim 1, wherein the casing is a box shape having an opening for the display and a clip integrally formed on a backside of the casing.

6. The system of claim 1, wherein the display is a liquid crystal display (LCD) display.

7. The system of claim 1, wherein the accelerometer is configured to measure the diaphragm movements within about 15 seconds a breath per minute (bpm) with an accuracy of about 2 bpm.

8. The system of claim 1, wherein the filtering process of the signals includes:

establishing a baseline for each axis component of the accelerometer once the device is powered on and attached to a patient;

determining an average acceleration for each axis component; and

interpreting measurements received from the accelerometer as deviations from the established baseline.

9. The system of claim 8, wherein the average acceleration outputs peaks for each movement of the diaphragm.

10. The system of claim 1, wherein the accelerometer is a one-axis, two-axis, or three-axis accelerometer.

11. The system of claim 1, further comprising a power source and a switch to turn the device on and off.

12. A method of measuring a respiratory rate, comprising:

measuring in real time, by an accelerometer, movement of a diaphragm by detecting tilts of the accelerometer;

processing and filtering, by a controller, signals associated with measurements from the accelerometer;

computing, by the controller, the respiratory rate based on filtered signals; and

converting, by the controller, the computed respiratory rate to a digital readout to output the digital readout on a display.

13. The method of claim 12, wherein a casing enclosing the accelerometer and the controller accelerometer is configured to be attached directly to a patient's abdomen using a removable adhesive.

14. The method of claim 12, wherein a casing enclosing the accelerometer and the controller accelerometer is attached to clothing of a patient for indirect contact with the abdomen.

15. The method of claim 14, wherein a casing enclosing the accelerometer and the controller accelerometer is attached to the clothing using a clip, a magnet, an adhesive, or other fastening mechanism.

16. The method of claim 12, wherein the casing is box shaped, has an opening for the display, and has a clip integrally formed on a backside of the casing.

17. The method of claim 12, wherein the display is a liquid crystal display (LCD) display.

18. The method of claim 12, further comprising:

measuring, by the accelerometer, the diaphragm movements within about 15 seconds a breath per minute (bpm) with an accuracy of about 2 bpm.

19. The method of claim 12, wherein the filtering further comprises:

establishing, by the controller, a baseline for each axis component once the device is powered on and attached to a patient;

determining, by the controller, an average acceleration for each axis component of the accelerometer; and

interpreting, by the controller, measurements received from the accelerometer as deviations from the established baseline.

20. The method of claim 12, wherein the accelerometer is a one-axis, two-axis, or three-accelerometer.
