Common Respiratory Disorders01:31

Common Respiratory Disorders

708
Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Other Pulmonary Disorders

Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.

Overview of Respiratory System

4.4K
The respiratory system is a complex biological apparatus that facilitates the exchange of gases, specifically oxygen and carbon dioxide, between our bodies and the environment. This system plays a vital role in the physiological process of respiration, an essential function for sustaining life.
What is the Respiratory System?
The respiratory system consists of a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary function of the respiratory system is to...

The Respiratory System01:16

The Respiratory System

82.5K
The respiratory system is comprised of the organs that enable breathing. Air enters the nostrils and mouth, followed by the pharynx (throat) and larynx (voice box), which lead to the trachea (windpipe). In the thoracic cavity, the trachea splits into two bronchi that allow air to enter the lungs. The bronchi split into progressively smaller bronchioles and terminate in small groups of tiny sacs in the lungs called alveoli, where gas exchange occurs.

Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

1.2K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Respiratory System Abnormal Finding I: Inspection and Percussion01:30

Respiratory System Abnormal Finding I: Inspection and Percussion

313
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Summary

This article reviews respiratory system anatomy, physiology, and common diseases like pneumonia and COPD. It guides nurses in respiratory assessment and identifying patient deterioration for improved care.

Area of Science:

  • Medical Sciences
  • Nursing Education

Background:

  • Respiratory diseases are prevalent in UK healthcare settings.
  • Nurses require a strong understanding of respiratory physiology and pathophysiology for effective patient care.

Purpose of the Study:

  • To summarize the fundamental anatomy and physiology of the respiratory system.
  • To explore pathophysiological changes in common respiratory conditions (pneumonia, lung cancer, asthma, COPD).
  • To outline comprehensive respiratory assessment and methods for detecting acute deterioration.

Main Methods:

  • Review of fundamental respiratory anatomy and physiology.
  • Exploration of pathophysiological changes in four common respiratory conditions.
  • Discussion of key elements in respiratory assessment and monitoring for deterioration.
