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

Transmission-based Precautions II: Airborne and Protective Environment

1.6K
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...

Asthma-I: Introduction

3.0K
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...

Asthma: Pathogenesis and Management

931
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Factors Affecting Pulmonary Ventilation

2.1K
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...

Asthma-II: Pathophysiology and Classification

3.5K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Area of Science:

  • Environmental Science
  • Public Health
  • Virology

Background:

  • The rapid global spread of SARS-CoV-2 (the virus causing COVID-19) has significantly impacted society.
  • Evidence suggests that COVID-19 can spread through bioaerosols, highlighting the importance of understanding transmission routes.

Purpose of the Study:

  • To review existing literature on the potential impact of airborne pollen on COVID-19 transmission.
  • To identify research gaps concerning the role of pollen bioaerosols in SARS-CoV-2 dispersal and survival.

Main Methods:

  • A literature review was conducted using key terms to gather relevant studies and observations.
  • Existing research on pollen, bioaerosols, and viral transmission was collated and analyzed.

Main Results:

  • A potential association between airborne pollen and COVID-19 transmission is suggested by current literature.
  • Limited studies specifically address the interaction between pollen bioaerosols and SARS-CoV-2.
  • Individuals with allergic rhinitis and asthma may possess pre-modified immune responses potentially offering some protection against COVID-19.

Conclusions:

  • Airborne pollen may act as a carrier for SARS-CoV-2, but this requires further multidisciplinary investigation.
  • More research is essential to determine how pollen bioaerosols affect virus survival and transmission.
  • Understanding this relationship can inform future public health measures against respiratory infectious diseases.
