Summary
Face masks prevent virus transmission through filtration, with performance depending on fabric texture and manufacturing methods. This study reviews primary and additive manufacturing techniques for improved mask quality control and effectiveness.
Area of Science:
- Materials Science
- Public Health
- Engineering
Background:
- Viruses, including SARS-CoV-2 (COVID-19), pose significant health risks through airborne transmission.
- Face masks serve as a critical barrier, reducing the spread of respiratory viruses via filtration.
- Mask filtration efficiency is intrinsically linked to fabric properties, which are determined by manufacturing processes.
Purpose of the Study:
- To explore the relationship between fabric texture, manufacturing methods, and face mask filtration performance.
- To highlight the importance of quality control through tests like leakage and dynamic respiratory resistance (DBR).
- To review established and emerging mask production techniques, including additive manufacturing (AM).
Main Methods:
- Review of primary non-woven fabric manufacturing methods: meltblown, spunlaid, drylaid, wetlaid, and airlaid.
- Inclusion of additive manufacturing (AM) techniques, specifically Fused Deposition Modeling (FDM).
- Discussion of essential quality control tests for mask performance evaluation.
Main Results:
- Fabric texture, dictated by manufacturing, significantly impacts filtration capabilities.
- Different manufacturing methods yield distinct fabric properties and filtration efficiencies.
- Additive manufacturing presents novel avenues for customized mask production.
Conclusions:
- Understanding manufacturing methods is key to optimizing face mask design and filtration.
- Rigorous quality control testing is essential for ensuring mask efficacy against airborne pathogens.
- Further research into additive manufacturing can lead to advanced protective equipment.

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.

01:10PPE Use in Healthcare Settings II: Doffing
1.2K
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.

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...

Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...
