Jackie,
The feeders are typically here 60-90 minutes. It all depends on how many patients need help and how chatty they are. We usually have 2-3 vols per shift covering two units, and sometimes they check on a third one if they have time. It's not unusual to have 5 patients on a unit who need help, whether it's just setups (opening milk, cutting pancakes, and other tasks that require dexterity the patient doesn't have) or full feeding.
