PPE Use in Healthcare Settings I: Donning

PPE Use in Healthcare Settings I: Donning

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...

Personal Protective Equipment

Personal Protective Equipment

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

PPE Use in Healthcare Settings II: Doffing

PPE Use in Healthcare Settings II: Doffing

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.

Body Water Content and Fluid Compartments

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions (Na+) and chloride...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

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...

Standard Precaution

Standard Precaution

Standard precautions are the minimum infection control safeguards used while caring for all patients, irrespective of their disease condition. They help prevent the spread of common infectious microorganisms to healthcare workers, patients, and visitors in all healthcare settings.
Hand hygiene is the most crucial means to prevent the transmission of disease. Employers are legally required to provide their workers with personal protective equipment (PPE) to minimize exposure or contact with...

Area of Science:

Occupational Health
Environmental Physiology
Protective Equipment

Background:

Working in warm environments while wearing respiratory protective masks can lead to progressive dehydration.
Dehydration poses significant health risks and can impair performance for workers in demanding conditions.

Purpose of the Study:

To evaluate the effectiveness of a portable hands-free, through-the-gas mask hydration system.
To assess its impact on workers in encapsulating protective coveralls (EPC) under heat stress.

Main Methods:

Ten participants performed simulated industrial work at a WBGT of 23°C.
Trials involved wearing impermeable and semipermeable EPC under two conditions: portable hands-free hydration system (PHFS) and typical rest-only hydration.
Work involved moderate intensity (300 Kcal/min) with hydration monitored.

Main Results:

Participants using the PHFS drank 242% more fluid in impermeable EPC trials compared to rest-only.
Dehydration was reduced to 21% in impermeable EPC and 41% in semipermeable EPC with PHFS compared to without.
Total work times remained unchanged, with a trend for longer walk times using PHFS in semipermeable EPC.

Conclusions:

The portable hands-free hydration system effectively mitigated hypohydration in workers wearing EPC in the heat.
This system offers a viable solution to combat dehydration and maintain worker health in hazardous environments.
Further research could explore optimal hydration strategies with PHFS in various protective ensembles.
