What is sound detection based breathing monitoring?

On the other hand, sound detection-based breathing monitoring allows a wearable solution, in which the breathing signal could be measured without restricting much the patient’s motion.

Why is breath monitoring important?

Therefore, breath monitoring is important, especially when you are medicated. Complications with your breathing can impact your healing and recovery. If a serious respiratory condition occurs and goes untreated, it can result in the need for intubation. Untreated respiratory conditions can also lead to brain damage or even death.

How does a breath monitor work?

Remember, the breath monitor is designed to alert your clinicians to early indications of a change in your breathing, so it is very important that you keep the nasal prongs inside your nose and keep the round “scoop” in front of your mouth so the breath monitoring system can do its job.

How does a sound-based breathing monitoring system work?

Fig. 2 shows a generic block diagram of the sound-based breathing monitoring system, where the sound is captured by a microphone. Then, the signal is processed through some analog circuits for filtering and amplification purposes.

Why do we measure breathing events using wearable sensors?

This chapter introduces the anatomy and physiology of the respiratory system, and the reasons for measuring breathing events, particularly, using wearable sensors. Respiratory monitoring is vital including detection of sleep apnea and measurement of respiratory rate.

Can a miniature wearable sensor record lung sounds and respiratory rate?

In summary, we presented a miniature wearable sensor system which can record lung sounds and respiratory rate with high-fidelity for both episodic and long-term monitoring of patients in an unobtrusive manner.

Can a wearable device record breath sounds?

For instance, Li, S.-H. et al. develop a wearable device that can record breath sounds and transfer them wirelessly to a host system using Bluetooth technology. It allows real-time monitoring of the patient outside the hospital. Some devices record not only respiratory sounds but chest movements [22-24].

Why are breathing sounds important?

For this reason, regular or routine monitoring of breathing sounds is essential for symptom prevention and alleviation, as well as for the early detection of various respiratory diseases [ 6, 7 ]. Typically, respiratory abnormalities are diagnosed by spirometry and auscultation [ 8 ].
