The proper maintenance of respiratory equipment

When we talk about disinfection, we talk about the prevention and control of infection in the environment. Therefore, equipment used for respiratory therapy is considered semi-critical. The equipment must then be cleaned and disinfected properly between patients. The WHO gives us the proper maintenance of respiratory equipment in procedures to follow. The procedures are checklists in steps of a cycle. Let’s explore all the summarized steps up to the cycle finish. And yes, the cleaning step is before the disinfection step!

Checklists for care, cleaning, disinfection and sterilization of respiratory devices

1. Perform hand hygiene

The title and image say it all

2. Don appropriate personal protective equipment

The personal protective equipment to be worn during the disinfectant preparation includes surgical mask/respirator, googles/face shield, long-sleeved fluid resistant gown/gown plus apron, rubber gloves and boots or closed work shoes.

3. Wash with detergent and rinse with clean water

The external device surfaces must be wiped with a damp cloth or disposable wipe that is soaked in detergent and clean water. Then, remaining detergent residue must be wiped off with a dry lint-free cloth. A mechanical action (scrubbing/brushing) should be used to remove visible dirt deposits and calcifications.

4. Disinfect

4a. Physical disinfection – Heat for heat resistant equipement (steam/hot-water)

A high-level of physical disinfection can be achieved with steam (e.g. autoclaving at lower temperature) or hot-water at least 121°C. This is an inexpensive and effective method for sterilization or high-level disinfection.

4b. Chemical disinfection for plastic plus other parts that can be damaged by heat

b) If the disinfection needs to be with chemicals solutions, it should be performed in a well-ventilated area and away from patients. Use a disposable wipe or a fresh cloth that is soaked in a compatible disinfectant. Hydrogen peroxide 0.5% or ethanol 70-90%. Wipe from top to bottom and avoid contact with electrical connectors.

5. Dry equipment / Rinse equipment

a) Physical equipment often has a drying feature within the machine (e.g. washer, pasteurizer or autoclave). Following pasteurization, the wet equipment is typically dried in a hot-air drying cabinet or air-dried. Make sure to carefully inspect and ensure that no water is left in the equipment.

b) If a chemical solution was used for disinfection, rinse the equipment with sterile or clean water (i.e. water boiled for 5 mins and cooled down). It is preferred to use sterile water for rinsing off residual liquid chemical disinfectant from the respiratory device.

6. Store equipment in closed packages

Last step. Title says it all.

Disinfection – The Power of Steam

Disinfection using disinfectant cleaners with active ingredients including alcohol and quaternary ammonium has often been discussed. Another disinfection solution is to disinfect with steam and pressure. Cleaning with the power of steam is a proven method of disinfection. Dry saturated steam at high temperatures kills viruses, bacteria, germs and bedbugs! It is an environmentally friendly and practical way to clean all kinds of surfaces.

THE POWER OF STEAM

The power of steam is to dissolve and emulsify grease, mold, dirt by vaporizing and killing viruses, bacteria and germs.

WHAT ABOUT SARS-CoV-2?

Despite that the power of steam kills viruses, bacteria and germs, opinions vary and there may be a lack of evidence that it can kill SARS-CoV-2 virus. The list of approved disinfectants put out by The Environmental Protection Agency only includes chemicals.

Patty Olinger, the executive director of the Global Biorisk Advisory Council, a division of ISSA (a cleaning industry trade association), said that, based on current evidence, while steam can kill the virus, it needs a lengthier application time than some users may realize.

On the other hand, Heidi Wilcox, a microbiologist and commercial cleaning consultant, says that: “At this point during the pandemic I would not use steam at all.” She cites a lack of strong evidence.

Then again, industry representatives such as Wayne Delfino from Advanced Vapor Technologies of Everett, Washington, insist that dry steam vapor works. The company’s non-chemical, “Thermo Accelerated Nano Crystal Sanitation” technology, he wrote in an email, “has been tested and proven effective on harder-to-kill viruses and on a similar human coronavirus in seven seconds or less.”

SURFACES TO CLEAN

Steam cleaners can clean and disinfect all kinds of surfaces. With the right tools, they can concentrate the jets to properly clean specific surfaces and hard-to-reach areas. Here are some examples:

  • Clothing
  • Mirrors
  • Seals (e.g. ceramic)
  • Mattresses and bedding
  • Stainless steel
  • Floors
  • Grids and hoods
  • ECOLOGICAL
  • Steam machines are said to be environmentally friendly because they require no chemicals. Only water is needed to steam disinfect and clean thoroughly.

NEED STEAMER MACHINES?

Power Steamer Machine JS 1600C

Power Steamer Machine JS 1600C

The power of steam from JS1600C attacks grease, grime, hard water deposits and mold. It leaves surfaces clean and sanitized without the use of chemicals. Operator safety is assured by the 12V waterproof switches and controls, a pressure switch, a high-limit thermal shutoff and an LED display informing the operator when the water level is low. The Energy saving safety system also automatically shuts off the machine if it’s idle for 60 minutes.

  • The tank can be filled while the unit is running, allowing for continuous use
  • Excellent on grouted floors, showers, kitchens and any area where detail cleaning is a challenge
  • Very effective in all food preparation and processing areas, including stainless steel range hoods in kitchens
  • Ideal for hotel rooms – spot draperies, bedspreads and carpets, and even kill bed bugs and their eggs on mattresses
  • Clean floors with the optional “steam mop” and 33′ hose
  • The continuous flow system provides the necessary steam to remove dirt and built-up soil while leaving your floors and surfaces virtually dry

Ecological Vapor with Vacuum A2006

Commercial Ecological Vapor with Vacuum A2006

The Vapore A2006 acts as two machines in one unit. The vapor not only dissolves dirt and grime, but is scientifically certified to disinfect any surface, thoroughly eliminating bacteria and viruses in an ecological way without use of chemicals.

  • With the water filtration system of the vacuum, Vapore A2006 collects dirt and traps it in the water without the risk of spreading dust
  • Vapore A2006 also has a HEPA filtration system to ensure the cleanliness of the air is not compromised
  • Equipped with a cold water reservoir, the Vapore A2006 has a continuous fill feature which allows you to refill the vapor system with water at any time, without stopping
  • The machine comes with a variety of floor accessory and tools

There’s no proof that the power of steam can kill SARS-CoV-2, but the virus is known to be sensitive to the exposure of high-temperature. Could it be a question of exposure length or a question of chemicals? However, the power of steam can be useful for general disinfection.
