Summary
Nonpharmacological interventions, including breathing retraining, may help dysfunctional breathing. However, evidence quality is low, and more detailed studies are needed for reliable efficacy.
Area of Science:
- Respiratory Medicine
- Rehabilitation Science
- Evidence-Based Practice
Background:
- Dysfunctional breathing is prevalent and negatively impacts asthma outcomes.
- Identifying effective nonpharmacological treatments is crucial for managing this condition.
Purpose of the Study:
- To characterize nonpharmacological interventions for dysfunctional breathing.
- To evaluate the evidence for their effectiveness.
Main Methods:
- Systematic search of multiple electronic databases for relevant studies.
- Assessment of intervention protocol characteristics using the Template for Intervention Description and Replication checklist.
- Evaluation of study quality and risk of bias.
Main Results:
- 68 trials with 2,119 participants were included, most with high or unclear risk of bias.
- Five intervention categories identified: breathing retraining, psychological therapy, acupoint therapy, manual therapy, and exercise therapy.
- Breathing retraining showed positive effects across biochemical, biomechanical, and psychophysiological domains, despite study heterogeneity and low evidence quality.
Conclusions:
- Various nonpharmacological interventions exist for dysfunctional breathing.
- Breathing retraining is the most studied, but evidence remains low-quality.
- Future research requires detailed reporting of interventions and consistent objective outcome measures.

Nursing management of Chronic Obstructive Pulmonary Disease (COPD) is crucial for providing thorough care and support to patients. Nurses play an integral role in this process through detailed assessment, careful planning, targeted interventions, and ongoing evaluation. Here's an overview of the critical steps in nursing management for COPD.

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
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...

01:27Physical Assessment of the Respiratory Tract II: Inspection
182
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

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:

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
2.7K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.
