Different Levels of Anesthesia in Healthcare Facility
It is essential to understand the different levels of sedation that may be administered. Although it is considered a sliding scale in most hospital OR’s, there are four distinct levels of anesthesia, based upon the patient’s physical response to the drug-induced state.
1. General Anesthesia
2. Deep Sedation/Analgesia
"Any area of a facility that has been designated to be used for the administration of general anesthesia."
In the 2018 edition of NFPA 99, this definition is no longer included, but as it relates to the design requirements of zone valves and area alarm panels, anesthetizing locations for moderate or deep sedation or general anesthesia are grouped into the same category.
“It shall be the responsibility of the health care facility’s governing body to designate anesthetizing locations.”
Anesthesia Safety: Requirements for Zone Valves and Area Alarm Locations
- Zone valves shall be located outside each anesthetizing location
- The zone valves shall be readily accessible
- Shutting off one zone valve shall not affect others
- Area alarm panels shall monitor all gas systems and provide surveillance of pressure variations of +/- 20% from normal operating pressure and vacuum decreases of 12in HgV
- The sensor locations for the area alarm panels may be installed on either the source side of individual room zone valve box assemblies or the patient side of each of the individual zone valve box assemblies
Medical gases are found throughout healthcare facilities, especially in anesthetizing locations such as operating rooms. Anesthetizing areas require a few special considerations during the planning and design stages. When completed correctly, the setting can provide an environment maximized for safety and the well-being of patients and staff.
