Assessment of Ventilation II: Respiratory Depth and Rhythm

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
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:

Area of Science:

Medical imaging
Ultrasound technology
Respiratory physiology

Background:

Ultrasound lung surface motion measurement is crucial for diagnosing various diseases.
Existing speckle tracking and Doppler methods face limitations due to visualization loss under ribs.

Purpose of the Study:

To develop and validate a novel synthetic lateral phase-based algorithm for lung motion tracking.
To overcome the limitations of current ultrasound-based lung motion assessment techniques.

Main Methods:

A synthetic lateral phase-based algorithm was developed for lung motion tracking.
Simulated lung motion images were generated for validation.
Lung ultrasound (LUS) cines were acquired from a healthy volunteer and a COVID-19 patient.

Main Results:

The algorithm achieved high accuracy, with measured displacement within 3% of ground truth in simulations.
Lung displacement was greatest in lower and lateral zones.
Respiratory pattern variations influenced measured displacement in the healthy volunteer.

Conclusions:

The synthetic lateral phase-based approach is a feasible method for estimating lung surface displacement.
Further studies are needed to validate this technique against direct lung surface movement measurements.
