Breathing mode assessment with thermography: a pilot study.

Purpose: To present a method for analyzing breathing modes with infrared thermography.

Methods: This exploratory cross-sectional study used 38 thermal images of inspiration and expiration with nasal breathing and simulated mouth breathing in four nasal breathers without respiratory complaints. Three different data selection forms (line, rectangle, and ellipse) were used to extract the minimum, mean, and maximum temperatures of the regions of interest (nose and mouth) using the FLIR Tools® software.

Evaluation of the breathing mode by infrared thermography.

Objectives: To analyze breathing modes with infrared thermography.

Methods: Cross-sectional observational exploratory study conducted in 20 female participants with a mean age of 26.0-years.
