Why is it Important?
Ensuring a proper seal is vital in preventing exposure to harmful substances. A failed seal can lead to
inhalation of infectious agents, which can compromise the safety of both the nurse and the patient. Effective seal checks contribute to preventing the spread of
diseases like
COVID-19,
tuberculosis, and other airborne illnesses.
When Should a User Seal Check be Performed?
A user seal check should be conducted each time the respirator is worn. This is especially necessary when the respirator is used for the first time, after any adjustments, or if the wearer feels that the respirator might have been displaced during use.
How to Perform a User Seal Check
Positive Pressure Test: Cover the exhalation valve or breathing tube, exhale gently, and feel for any air leaking out from the edges of the mask. If air leaks, reposition the respirator and try again.
Negative Pressure Test: Cover the inhalation valves, inhale gently, and hold your breath for a few seconds. The mask should collapse slightly on your face without any air leakage. If it does not, adjust the respirator and try again.
Common Issues and Solutions
Facial Hair: Facial hair can interfere with the seal of the respirator. It is recommended to shave or use a
respirator designed for bearded individuals.
Improper Fit: Make sure the respirator is the correct size. Different models and sizes might be necessary to achieve an optimal fit.
Defective Respirator: Inspect the respirator for any defects or wear and tear. Replace it if necessary.
Training and Education
Nurses should receive proper
training on how to perform user seal checks. This includes hands-on practice and educational resources. Institutions should provide regular refresher courses to ensure compliance and update on the latest guidelines.
Regulatory Guidelines
Regulatory bodies such as
OSHA and the
CDC provide guidelines and recommendations on the proper use of respirators and the necessity of user seal checks. Adhering to these guidelines helps maintain a high standard of
safety in healthcare settings.
Conclusion
Performing a user seal check is a simple yet essential practice in nursing to ensure the safety of both healthcare professionals and patients. By understanding the importance, knowing when and how to perform the check, and being aware of common issues, nurses can effectively use respirators to protect against airborne hazards.
