Challenges and Successes

  • Issues: During the functional testing of the humidifiers it was discovered that there was no installed sensors for humidity control. This is extremely important in the Isolation rooms located on each floor.

          Resolution: by adding humidity level sensors in the return ductwork and programming set points in the BAS. Currently there are alarms if the levels go beyond their set points as well as the ability to manipulate the desired levels. Before the change were made the humidifiers basically ran free, with constant addition of humidity to the area.  As a result, patient comfort during their stay can be ultimately achieved. Making their stay a memorable and relaxing one.

  • Issues: It was identified that the Isolation Room Fans were not properly tied to the BAS system. There are many reasons why this creates a dangerous environment for the patients in and around the ISO rooms. No monitoring, Alarming or set points were present prior to our functional testing procedures.

         Resolution: the controls contractor added the necessary points for alarming and set points to the automation system. With the addition of the parameters to the system, it now runs automatically. The system operating at its peak level and running properly, helps to control the spread of potentially harmful germs to the other patients with already weakened immune systems.
