Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

4.9K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

The Bronchial Tree01:23

The Bronchial Tree

8.4K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Asthma-I: Introduction

3.7K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

COPD: Management Using Bronchodilators and Corticosteroids

1.2K
Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Atypical Pneumonia01:14

Atypical Pneumonia

49
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...

Chronic Obstructive Pulmonary Disease01:24

Chronic Obstructive Pulmonary Disease

3.2K
COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Area of Science:

  • Respiratory Medicine
  • Evidence-Based Medicine
  • Clinical Pharmacology

Background:

  • Acute bronchitis is a common condition affecting over 4% of UK adults annually.
  • Infectious agents are often implicated, yet pathogens are identified in only half of cases.
  • The influence of smoking on acute bronchitis development and recurrence requires further investigation.

Purpose of the Study:

  • To systematically review the effectiveness and safety of various treatments for acute bronchitis in individuals without chronic respiratory conditions.
  • To answer the clinical question regarding the effects of different interventions for acute bronchitis.

Main Methods:

  • A comprehensive systematic review was conducted, searching major medical databases up to May 2015.
  • The review included screening of 306 records, with 61 full publications evaluated.
  • GRADE evaluations were performed for 12 PICO (Population, Intervention, Comparison, Outcome) combinations.

Main Results:

  • The review categorized the efficacy of six intervention-comparison groups.
  • Evaluated interventions included antibiotics, antihistamines, antitussives, inhaled beta2 agonists, and expectorants/mucolytics.
  • Data on the effectiveness and safety of these treatments were synthesized.

Conclusions:

  • The systematic review provides a categorization of treatment efficacy for acute bronchitis.
  • Limited evidence exists for the effectiveness of common treatments like antibiotics and cough suppressants.
  • Further research is needed to establish clear treatment guidelines for acute bronchitis.
