How long will the patient Contact Be
Will the device be in contact with the patient cumulatively less than 24 hours, less than 30 days or greater than 30 days?
The next step in the process is to accurately describe the patient contact time. Less than 24 hours is considered limited contact. Greater than 24 hours but less than 30 days is considered to be prolonged contact. Greater than 30 days is considered permanent. Bear in mind, that the exposure your considering should be viewed as cumulative. If the device is changed daily for a period that could be longer than 30 days, this is a permanent exposure.
