Monitor the breath with the radio transceiver

A breath-taking radio monitoring system called 'Breath Taking' developed by Neal Patwari and the research team at the University of Utah recently promises to be a powerful tool. For observers who are recovering from surgery, people with sleep apnea syndrome and those who are at risk of SIDS.

The system consists of a network of wireless radios that are widely available on the market lining the sides, ends and ends of patients' beds.

Each radio transceiver transmits and receives signals from all the other machines and then sends the signal to another machine.

However, as the chest and abdomen of the patient bulge and collapse, so as not to interfere with the wireless signal through the bed.

A computer algorithm will process the data from the transmitter and then determine when the object stops breathing when it detects that the interval between bursts is too long.

The superiority of this system is that there is no need to attach anything to the patient's body like other traditional breath monitoring systems. In addition, the system has low cost and high accuracy.

To test the system, Patwari has used 20 transceivers and detected at least 13 machines with minor bugs and at least 19 machines that resulted in no problems. The height of the transceivers placed does not affect the accuracy of the monitoring.

Currently, the University of Utah team is studying the use of various radio frequencies for the system to detect how many different people are breathing in a room. If successful, this feature will be very useful for hostage rescue situations.

Patwari said that at least five years from now, the system will be available in the market.
