Transmission-based Precautions II: Airborne and Protective Environment01:25

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Common Respiratory Disorders01:31

Common Respiratory Disorders

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,...
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Respiratory Assessment: Purpose and Indications01:19

Respiratory Assessment: Purpose and Indications

Respiratory assessment is a cornerstone of nursing assessments, crucial for the early detection of patient deterioration. This evaluation transcends routine procedures, representing a critical skill nurses must master to ensure optimal patient care.
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
Pneumonia I: Introduction01:30

Pneumonia I: Introduction

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...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

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...

Area of Science:

  • Occupational Health
  • Infectious Diseases
  • Public Health

Background:

  • Rising concern over nosocomial transmission of extensively drug-resistant tuberculosis (TB).
  • Increased risk of occupational infectious illnesses from avian influenza (H5N1), SARS-CoV, and pandemic H1N1 influenza.
  • Heightened awareness of respiratory infection threats in healthcare and agricultural sectors.

Purpose of the Study:

  • Review research on transmission modes, patterns, determinants, and extent of occupational respiratory infections.
  • Summarize key findings on risks, determinants, and preventive measures for these infections.
  • Present recent guidelines for controlling occupational infectious illnesses.

Main Methods:

  • Literature review of research from the past decade.
  • Analysis of findings on transmission dynamics and risk factors.
  • Synthesis of evidence-based preventive strategies and guidelines.

Main Results:

  • Extensively drug-resistant tuberculosis (TB) poses significant nosocomial transmission risks.
  • Avian influenza (H5N1), SARS-CoV, and H1N1 influenza outbreaks highlight occupational infectious disease threats.
  • Effective administrative, personal (N95 respirators), and engineering controls are identified for respiratory infection mitigation.

Conclusions:

  • Administrative, personal, and engineering controls are effective in healthcare settings.
  • N95 respirators are strongly recommended for healthcare workers managing TB and viral respiratory infections.
  • Influenza vaccination and ultraviolet germicidal irradiation are effective and recommended preventive measures.
