What do the two pressure gauges on a steam sterilizer measure?

• A. Temperature of the chamber
• B. Humidity levels inside the sterilizer
• C. Pressure in the jacket and chamber
• D. Rate of steam flow

Answer: (C)

The two pressure gauges on a steam sterilizer are designed to measure the pressure in both the jacket and the chamber. The jacket pressure is important as it helps to maintain the necessary temperature for effective sterilization by providing a consistent heat source, while the chamber pressure measures the internal atmosphere where the instruments are sterilized. Maintaining the correct pressures is crucial to ensure that steam condenses properly and that adequate conditions for killing microorganisms are achieved within the sterilization load. This ensures that the steam sterilizer operates effectively, enabling the successful sterilization of medical instruments and equipment. Understanding the roles of these gauges is essential for anyone involved in the sterile processing department, as it directly impacts the efficacy and safety of sterilization practices.
