To change the interval, open up the pre-op page, down the bottom left you will see a field 'Show intervals', here you can select the 'q' you desire.

We all know how things can change more often than every 5 minutes with anesthetized patients. With this in mind we designed the Anesthetic sheet with the ability to enter vitals q1min, q5min, q10min, q15min or q30min. 

Please note that once you press "Save" the interval can not be changed so be sure to select and appropriate interval before pressing "Save".
