Abstract:
Although concerns about and precautions to prevent transmission of diseases through the air have existed since Hippocrates, renewed interest in risks and prevention strategies grew significantly since the onset of the COVID-19 pandemic. This altered respiratory care practice globally owing to concerns that some respiratory care procedures may generate or disperse aerosols that could spread pathogens. A paucity of evidence, as well as a lack of general consensus, existed at the pandemic onset to determine the associated risks of these procedures and best practices for mitigating those risks. This is a review of key peer-reviewed manuscripts from 2023 to 2024 discussing aerosol generation and dispersion from respiratory care procedures, as well as the mitigation of associated risks. A brief discussion of different forms of aerosols, and the risks associated with each, is also included.

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...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...
