Biomedical Instrumentation & Technology
|December 18, 2020
Summary
The COVID-19 pandemic created critical shortages of personal protective equipment. Processing single-use respirators and surgical masks using dry heat at 80°C for 120 minutes is an effective solution.
Area of Science:
- Healthcare preparedness
- Infectious disease control
- Biomedical engineering
Background:
- The COVID-19 pandemic, caused by SARS-CoV-2, led to unprecedented demand for personal protective equipment (PPE).
- Critical shortages of single-use respirators and surgical masks challenged healthcare facilities globally.
- PPE, including masks and respirators, is vital for reducing the risk of airborne particle and microbial inhalation.
Purpose of the Study:
- To evaluate processing methods for single-use respirators and surgical masks.
- To address critical shortages of essential PPE during the COVID-19 pandemic.
- To confirm the efficacy of a specific decontamination method for reuse.
Main Methods:
- Investigated the dry heat processing method.
- Utilized a temperature of 80°C (176°F).
- Applied the process for a duration of two hours (120 minutes).
Main Results:
- The dry heat process at 80°C for 120 minutes was confirmed as appropriate.
- This method addresses the critical need for PPE processing due to high demand.
- Demonstrated a viable strategy for managing shortages of single-use respirators and surgical masks.
Conclusions:
- Dry heat processing is a suitable method for decontaminating single-use respirators and surgical masks.
- This technique can help alleviate PPE shortages in healthcare settings.
- Confirms the feasibility of reusing essential respiratory protection equipment through validated processing.

01:29Methods of Sterilization I: Physical Methods
22.9K
As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

01:10PPE Use in Healthcare Settings II: Doffing
1.3K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

1.5K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
