Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Pulmonary Cycle: Exhalation

Pulmonary Cycle: Exhalation

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...

Asthma I: Introduction

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Factors Affecting Pulmonary Ventilation

Factors Affecting Pulmonary Ventilation

Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

The Bronchial Tree

The Bronchial Tree

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...

Pressure Relationships in Thoracic Cavity

Pressure Relationships in Thoracic Cavity

Breathing, otherwise known as pulmonary ventilation, is the process of air movement into and out of the lungs. The main mechanisms propelling pulmonary ventilation are atmospheric pressure (Patm), intra-pulmonary (Ppul ) or intra-alveolar pressure (Palv) within the alveoli, and intrapleural pressure (Pip) within the pleural cavity.
Breathing Mechanisms
Both intra-alveolar and intrapleural pressures rely on specific lung properties. The ability to breathe—allowing air to enter the lungs during...

Summary

Lung function testing in infants with bronchiolitis is challenging. The interrupter technique effectively measures airway resistance in unsedated young children during and after acute bronchiolitis.

Area of Science:

Pediatric Pulmonology
Respiratory Physiology

Background:

Assessing lung function in infants with bronchiolitis is crucial for treatment but faces challenges like sedation needs and lack of standardization.
The interrupter technique offers a potential solution for evaluating airway function in this age group.

Purpose of the Study:

To evaluate lung function changes using the interrupter technique in unsedated wheezing children under three years old during and after acute bronchiolitis.

Main Methods:

A cohort study enrolled children under three with acute bronchiolitis.
Interrupter resistance (Rint) measurements were taken using a face mask during and after the acute phase.
Data on bronchiolitis severity, duration, and hospitalization were recorded.

Main Results:

A significant decrease in expiratory Rint values was observed after clinical bronchiolitis findings resolved (1.08 vs. 0.80 kPa.L-1.s).
Flow measurements remained stable, while mouth pressure decreased significantly post-illness.

Conclusions:

The interrupter technique demonstrated higher airway resistance during acute bronchiolitis in young children.
Rint measurements can detect changes in airway function in unsedated infants with bronchiolitis in ambulatory settings.
