Columbia University Emergency Medical Service
Columbia University Emergency Medical Service (CU EMS), formerly known as Columbia Area Volunteer Ambulance (CAVA), is Columbia's ambulance service, and the preferred mode of transportation for inebriated freshmen looking for a ride to St Luke's Hospital.
CAVA is also a verb in Columbia slang. For example, you might get so drunk that you need to be CAVAed.
You can reach CU EMS by dialing *99 on a ROLM phone or 212-854-5555 from off-campus.
