What is the average patient load outpatient?

I work in a sleep and pulmonology clinic and it’s about 22 patients a day. A good chunk of the visits are definitely simple cpap etc but there are also more complex pulm visits. Another midlevel I work with has been there for a few years and still seems pretty stressed much of the time. Wondering if most other outpatient specialties are in the same boat as far as patient load.
