Breathing

64.5K
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...

Introduction to Inspiration: The Respiratory System in Action
The respiratory system, an essential network for breathing, comprises the conducting and respiratory zones, each playing a crucial role in the overall process of respiration. Let us explore the detailed mechanism of inspiration, or inhalation, which is the first phase of the respiratory cycle.
Pathway of Air during Inspiration
During inspiration, air enters our body through the nose or mouth and moves through the conducting zone,...

The Physiology of Expiration: A Seamless Respiratory Process
Expiration, or exhaling, is a complex physiological process that begins as the inspiratory muscles begin to relax. This relaxation triggers a series of events that epitomize the efficiency of the respiratory system.

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

Lung Capacity01:47

Lung Capacity

56.3K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Area of Science:

  • Respiratory Medicine
  • Pulmonology
  • Clinical Practice

Background:

  • Dysfunctional breathing (DB) presents with irregular breathing patterns, often causing dyspnea or 'air hunger', and non-respiratory symptoms like dizziness.
  • DB affects all age groups, with a 9.5% prevalence in UK primary care adults and significant rates in asthma patients.
  • Despite decades of research, DB remains poorly understood due to limited high-quality trials and specific outcome measures.

Purpose of the Study:

  • To review and summarize existing evidence on Dysfunctional Breathing (DB).
  • To enhance the understanding of DB for both researchers and healthcare practitioners.
  • To address the underdiagnosis and misdiagnosis of DB by highlighting its complex nature.

Main Methods:

  • This study employed a narrative review methodology.
  • It synthesized available evidence regarding Dysfunctional Breathing (DB).
  • The review focused on improving comprehension among clinicians and researchers.

Main Results:

  • Dysfunctional breathing (DB) is frequently misdiagnosed due to symptom overlap with conditions like COPD and asthma.
  • Healthcare professionals' limited understanding contributes to underdiagnosis and inappropriate treatment.
  • The psychophysiological complexity of DB necessitates a holistic, multidimensional assessment approach.

Conclusions:

  • A comprehensive, multidimensional assessment is crucial for accurate DB diagnosis.
  • Improved understanding of DB by healthcare professionals is essential for effective patient management.
  • Further research and validated outcome measures are needed to advance the field of Dysfunctional Breathing.
