Background:
When learning and improving singing, the quantitative characterization of artists' performances based only on vocal parameters does not provide enough information to identify strategies for improvement. Simultaneous monitoring of sound production and breathing patterns in professional singers can allow the exploration of the mechanisms that promote effective singing modalities through association with respiratory efforts.
Methods:
We developed and tested a novel portable device that simultaneously monitors vocal activity and breathing patterns without interfering with natural singing. The device utilizes a combination of a miniature accelerometer to measure vocal doses from skin vibrations on the neck and two respiratory inductive plethysmography (RIP) bands to estimate the breathing pattern by measuring changes in the thoracoabdominal cross-sectional area.
Results:
The device was tested on 13 professional baroque-style singers and 14 untrained individuals during the execution of singing tasks. It was accurate compared with reference systems (R2 = 0.99 and R2 = 0.91 for the accelerometer and RIP, respectively) and showed differences between the two groups (p ≤ 0.001).
Conclusions:
By allowing a quantitative characterization of the effectiveness of singing technique, this novel device can help provide a better understanding of the physiology of singing and may be a tool for support learning and training optimization for professional singers.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
