Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

5.2K
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...

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

40
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...

Pneumonia I: Introduction01:29

Pneumonia I: Introduction

24
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

1.5K
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Asthma I: Introduction01:28

Asthma I: Introduction

112
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...

Breathing01:05

Breathing

50.6K
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...

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Respiratory Medicine

Background:

  • Acute viral bronchiolitis is a frequent cause of infant emergency room visits.
  • Physicians frequently encounter this condition in acutely ill children.

Purpose of the Study:

  • To summarize the epidemiology, pathophysiology, and diagnosis of viral bronchiolitis in infants.
  • To provide guidelines for the treatment of bronchiolitis in infants.

Main Methods:

  • Review of current literature on viral bronchiolitis.
  • Focus on established and emerging treatment strategies.
  • Discussion of supportive care and respiratory support.

Main Results:

  • Cornerstones of management include oxygen administration and fluid therapy.
  • A "minimal handling approach" is recommended.
  • Inhaled adrenaline has sparse evidence; hypertonic saline is an optional treatment.

Conclusions:

  • Non-invasive and invasive ventilation may be necessary for respiratory failure.
  • Treatment algorithms should be applicable across care levels and reflect local factors.
  • Effective management requires a comprehensive approach to infant respiratory illness.
