Comprehensive Isolation Room Monitoring
By: CAS DataLoggers
Continual hospital monitoring of room air pressure is an effective form of leak detection. Facility personnel can monitor the negative pressure of the isolation room space by mounting a measurement pod connected to a pressure transducer, measuring the difference between the pressure inside the room and the pressure in the general environment outside the room walls. This prevents microbes and other contaminants from crossing the sterile barrier, especially for areas with infectious disease concerns. Monitoring of ambient temperature and humidity also helps optimize conditions to minimize microbial growth.
In this application, an Accsense A1-01a Environmental pod continually monitors the differential pressure in the isolation room. In the event of a loss of negative pressure, the Accsense will immediately send out alarms to multiple recipients so that staff can be notified in time to take corrective actions. Each Accsense Wireless A1-01a data logger is equipped with an internal ambient temperature and humidity sensor, plus 4-20mA and 0-5V analog inputs to connect to external sensors. The pod also features 2 digital inputs that can be used to monitor switches to record door open/closing events.
Accsense will notify staff whenever the differential pressure drops or when the temperature and humidity go outside preset limits. The system will continue to log during power or internet outages and the offsite server will generate a loss of communication alarm to notify users of a loss of connection due to a power loss or network connectivity. This provides Accsense users with added peace of mind knowing that even if communications fail they will still be alerted to take immediate action.
