Certified Hyperbaric Technologist Practice Test

In hyperbaric chambers, which of the following materials is recommended for patient garments?

1. Material that is 100% synthetic

2. Specialized fire-resistant materials

3. Blended materials of cotton and polyester

4. Any natural fiber

The correct answer is: Blended materials of cotton and polyester

The recommendation for patient garments in hyperbaric chambers emphasizes safety and functionality. Blended materials of cotton and polyester are particularly suitable due to their breathable properties, which help regulate body temperature and provide comfort during treatments. These blends are often designed to minimize the risk of static electricity, an important consideration in hyperbaric environments where oxygen levels are elevated. Additionally, cotton contributes to moisture-wicking, which can keep patients dry and comfortable, while polyester enhances durability and maintains shape after multiple washes. This combination creates garments that are not only comfortable for patients undergoing treatments but also safe, as they can withstand the unique conditions present in hyperbaric chambers. In contrast, materials that are purely synthetic may increase the risk of static buildup, while natural fibers, although comfortable, may lack the durability and moisture management needed in this specific setting. Specialized fire-resistant materials are typically important in environments with high-risk activities involving flames, rather than for the standard usage of hyperbaric chambers where the focus is on providing a comfortable and safe atmosphere for patients.
