Selecting the Right PPE: A Focus on AAMI Level 2 Isolation Gowns
Introduction:
In the realm of healthcare, ensuring the safety of healthcare workers and patients is a top priority. Personal Protective Equipment (PPE), such as isolation gowns, plays a pivotal role in maintaining this safety by providing a barrier between healthcare workers and potential infectious agents. The American National Standards Institute/Association of the Advancement of Medical Instrumentation (ANSI/AAMI) has established a classification system for protective apparel used in healthcare facilities based on their liquid barrier performance. This article will delve into the specifics of AAMI Level 2 isolation gowns, providing a comprehensive guide on their selection and use.
Understanding AAMI Standards:
The ANSI/AAMI PB70 standard provides a systematic approach for manufacturers to test and classify a product’s barrier performance. This allows clinicians to select the appropriate level of protection based on the specific procedures being performed. The standard classifies gowns into four levels, with Level 1 offering the lowest level of protection and Level 4 offering the highest.
AAMI Level 2 Isolation Gowns:
AAMI Level 2 isolation gowns are designed for situations with a low risk of contamination. These situations could include procedures like blood draw, suturing, or working in the Intensive Care Unit (ICU) or a pathology lab. The critical zones of these gowns, including the front of the body and the arms, must meet at least Level 2 liquid barrier performance. This means that these areas of the gown are resistant to water impact and some resistance to water penetration under light to moderate pressure.
In addition to their barrier performance, AAMI Level 2 gowns also have specific design features. They typically have long sleeves and a full back, providing coverage for the upper body. They also have ties or fasteners at the neck and waist to ensure a secure fit. Some gowns may also have elastic or knit cuffs for added comfort and security.
Selecting the Right AAMI Level 2 Isolation Gown:
When selecting an AAMI Level 2 isolation gown, several factors should be considered. One of the most important is the gown’s compliance with AAMI standards. Look for gowns that are clearly labeled as meeting Level 2 performance criteria according to the ANSI/AAMI PB70 standard.
The fit and comfort of the gown are also important. The gown should provide full body coverage and should be comfortable to wear for extended periods. Features such as elastic or knit cuffs, ties or fasteners at the neck and waist, and a full back can enhance the gown’s fit and comfort.
The gown’s material is another important consideration. Look for gowns that are made from materials that are resistant to fluid penetration but also breathable. Some common materials used in AAMI Level 2 gowns include polypropylene, polyester, and polyethylene.
Using AAMI Level 2 Isolation Gowns:
AAMI Level 2 isolation gowns play a crucial role in infection control in healthcare settings. By providing a barrier between the healthcare worker and potential sources of infection, these gowns can significantly reduce the risk of disease transmission.
In addition to their use in patient care, AAMI Level 2 isolation gowns are also used in other areas of healthcare facilities. For example, they may be worn by personnel who are cleaning rooms or equipment that have been used in the care of patients with infectious diseases.
AAMI Level 2 Isolation Gowns in the Context of COVID-19:
The COVID-19 pandemic has underscored the importance of PPE in protecting healthcare workers. During the pandemic, the demand for PPE, including isolation gowns, has increased dramatically. AAMI Level 2 isolation gowns have been widely used in healthcare settings during the pandemic due to theirbalance of protection and comfort.
While AAMI Level 2 gowns provide a lower level of protection than Level 3 or Level 4 gowns, they are sufficient for many situations encountered in the care of COVID-19 patients. For example, they can be used by healthcare workers who are providing routine care for COVID-19 patients or by those who are performing procedures that do not involve high levels of aerosol generation.
However, it’s important to note that the selection of PPE, including isolation gowns, should always be based on a risk assessment. This assessment should consider the type of activities the healthcare worker will be performing, the likelihood of exposure to infectious agents, and the potential for fluid penetration.
The Role of AAMI Level 2 Isolation Gowns in Infection Control:
Infection control in healthcare settings involves a multi-faceted approach, and PPE is a key component of this approach. By providing a barrier between the healthcare worker and potential sources of infection, PPE can significantly reduce the risk of disease transmission.
AAMI Level 2 isolation gowns play a crucial role in this regard. By protecting the wearer’s body and clothing from contact with potentially infectious material, these gowns can prevent the wearer from becoming contaminated and potentially spreading the infection to others.
In addition to their use in patient care, AAMI Level 2 isolation gowns are also used in other areas of healthcare facilities. For example, they may be worn by personnel who are cleaning rooms or equipment that have been used in the care of patients with infectious diseases.
Choosing the Right AAMI Level 2 Isolation Gown:
When choosing an AAMI Level 2 isolation gown, there are several factors to consider. One of the most important is the gown’s compliance with AAMI standards. Look for gowns that are clearly labeled as meeting Level 2 performance criteria according to the ANSI/AAMI PB70 standard.
The fit and comfort of the gown are also important. The gown should provide full body coverage and should be comfortable to wear for extended periods. Features such as elastic or knit cuffs, ties or fasteners at the neck and waist, and a full back can enhance the gown’s fit and comfort.
The gown’s material is another important consideration. Look for gowns that are made from materials that are resistant to fluid penetration but also breathable. Some common materials used in AAMI Level 2 gowns include polypropylene, polyester, and polyethylene.
Conclusion:
Selecting the right PPE is a critical aspect of ensuring the safety of healthcare workers and patients. AAMI Level 2 isolation gowns offer a balance of protection and comfort, making them a suitable choice for situations with a low risk of contamination. By understanding the features and benefits of these gowns, healthcare facilities can make informed decisions about PPE, ensuring that their staff are adequately protected while they provide care to patients.
As we navigate the challenges of healthcare in the 21st century, the importance of PPE, including AAMI Level 2 isolation gowns, cannot be overstated. By choosing the right PPE and using it correctly, we can protect our healthcare workers and patients, and help to prevent the spread of infectious diseases.
