Regional pulmonary function testing: a new tool for screening subjects with preserved ratio impaired spirometry?

Area of Science:

• Medical Imaging
• Pulmonology
• Biomedical Engineering

Background:

• Traditional spirometry is a standard method for assessing lung function but may not fully capture regional variations.
• Respiratory impairments significantly impact patients' quality of life and symptom presentation.

Discussion:

• Electrical impedance tomography (EIT) provides real-time, regional lung function data.
• EIT-based assessments demonstrated a stronger correlation with patient-reported symptoms and quality of life compared to spirometry.

Key Insights:

• Feasibility of using EIT for detecting respiratory impairments.
• EIT offers a more sensitive measure of respiratory system health than spirometry.
• EIT data aligns better with clinical presentation and patient experience.

Outlook:

• Potential for EIT to become a standard tool in respiratory diagnostics.
• Further research into EIT applications for various lung diseases.
• Integration of EIT into clinical workflows for improved patient management.
