Should you be receiving treatment notifications from Smart Flow but, you are not seeing any due on the flowsheets, the most likely cause is a patient that is not current. 

Check each patients flowsheet and then check the date, is there a patient that does not have a flowsheet for the current date? This is most likely where your missed treatment will be. Another way you can tell that a patient doesn't have a current flowsheet is the whiteboard will appear as shown below.

As you can see "Smitty" doesn't appear to have any yellow highlighting on the whiteboard: 

If you are seeing red number marks on the patient info profile (as pictured below), this indicates that highlighting on the flowsheet is passed the current hour, so it appears as a missed treatment.
