Physical Assessment of the Respiratory Tract III: Percussion

Physical Assessment of the Respiratory Tract III: Percussion

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

Area of Science:

Medical Imaging
Respiratory Physiology
Ultrasound Technology

Background:

Diaphragm excursion is a key indicator of respiratory function.
Current methods like M-mode ultrasound have limitations in fully capturing diaphragm movement.

Purpose of the Study:

To introduce and evaluate a novel ultrasound speckle tracking method for diaphragm excursion measurement.
To compare the new speckle tracking technique with the traditional M-mode method.

Main Methods:

Ultrasound images of the right and left hemidiaphragms were acquired.
Diaphragm movement was measured using both speckle tracking and M-mode techniques.
The study included six healthy subjects.

Main Results:

Speckle tracking is technically feasible for diaphragm assessment.
Speckle tracking provides reliable visualization and measurement of the left hemidiaphragm, unlike M-mode.
Speckle tracking captures 2D movement (cephalocaudad and mediolateral), whereas M-mode is 1D.

Conclusions:

Diaphragm speckle tracking is a promising novel method for measuring diaphragm excursion.
This technique offers a more robust assessment of respiratory function, particularly for the left hemidiaphragm.
