If the patient’s vital signs are monitored with Visi Mobile, the chest sensor should be removed from the chest securements if it will interfere with the quality of imaging of chest CT scans, chest X-rays, etc. To remove, lift the chest sensor out of the chest securement. There is no need to remove the clear plastic securement from the patient’s chest or arm if you intend to add ViSi Mobile back onto the patient after their scan.
