Inhaled Medications01:23

Inhaled Medications

316
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

715
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

392
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Transmission-based Precautions II: Airborne and Protective Environment

1.3K
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...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

711
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
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,...

Area of Science:

  • Pulmonary Medicine
  • Infectious Disease Control
  • Healthcare Management

Background:

  • Patient-specific metered-dose inhalers (MDI) are ideal but faced shortages during the COVID-19 pandemic.
  • Nebulized medications posed infection risks to healthcare workers due to potential aerosolized virus.
  • Limited MDI availability and infection control concerns necessitated alternative strategies.

Purpose of the Study:

  • To implement and evaluate a comprehensive MDI canister reassignment program.
  • To address medication shortages and mitigate infection risks associated with nebulizers.
  • To ensure continuity of bronchodilator therapy during the COVID-19 pandemic.

Main Methods:

  • A 4-component MDI canister reassignment process was developed and implemented across a large healthcare system.
  • Components included supply preservation, reassignment workflow, canister cleaning, and operational integration.
  • Albuterol MDI administration data was monitored from January to August 2020.

Main Results:

  • Nebulizer use decreased by 60% after MDI reassignment implementation.
  • A sustained reduction of over 50% in nebulizer use was observed through August 31st.
  • This shift occurred in 162 hospitals within the healthcare system.

Conclusions:

  • MDI canister reassignment was crucial for maintaining bronchodilator therapy for COVID-19 patients.
  • The program served as an effective infection prevention strategy for healthcare providers.
  • This initiative addressed critical supply chain and patient safety issues during the pandemic.
