This study shows that the Breathing-Mentor app effectively trains abdominal breathing using biofeedback. While immediate relaxation effects aren't guaranteed for new users, the app demonstrates feasibility for stress management.
Area of Science:
- Biomedical Engineering
- Health Technology
- Behavioral Science
Background:
- Deep, slow abdominal breathing is crucial for managing stress and pain.
- Current breathing apps often lack sensor-based biofeedback on actual breathing behavior.
Purpose of the Study:
- To evaluate user feedback and breathing behavior with the novel Breathing-Mentor app.
- To assess the impact of biofeedback integration in a mobile breathing application.
Main Methods:
- Developed two versions of the Breathing-Mentor app: one with visual instruction only, and one with added biofeedback.
- Randomly assigned 40 untrained participants to use one app version for 5 minutes.
Main Results:
- The biofeedback group showed improved breathing frequency accuracy (increased signal-to-noise ratio).
- Self-reported relaxation was lower in the biofeedback group, potentially due to higher cognitive load.
Conclusions:
- The Breathing-Mentor app is feasible and useful for training abdominal breathing with biofeedback.
- Untrained users may not experience immediate relaxation benefits.

Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Alterations in Respiration II
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

However, the ability to hold one's breath voluntarily is not limitless. When the CO2 concentration in the blood reaches a critical level,...
Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
