Here's what I use:

caesuraOn = \override BreathingSign #'text = 
#(make-musicglyph-markup "scripts.caesura.straight") 

caesuraOff = \revert BreathingSign #'text 
caesura = { \once \caesuraOn \revert BreathingSign #'Y-offset \breathe }
breath  = { \caesuraOff \override BreathingSign #'Y-offset = #5 \breathe }

I then use \caesura or \breath where I need them.
