1. Here does R/O mean CVA or OSA had been "ruled out" meaning CVA/OSA has been diagnosed as NOT the issue anymore?
or
2. Does R/O mean in order to "rule out" CVA, Ct result must read negative with no neuro deficit etc..... or in the case of OSA, in order to "rule out" OSA, an O/N oximetry & referral to RT needs to occur to establish a diagnosis?
My client was admitted with confusion, delirium & possible TIA or CVA. My client might have obstructive sleep apnea, OSA, as well.
In my doctor's progress notes it states...
R/O CVA - Ct read negative, no neuro deficit, confusion resolved
R/O OSA - O/N oxymetry & RT to see for CPAP
