Commonwealth Health Emergency Medical Services offers critical care medical transportation – both in the air and on the ground.

CHEMS provides advanced lifesaving treatment to patients en route to hospitals throughout the region with a critical care team that includes a pre-hospital registered nurse (PHRN) and a critical care paramedic.​

Critical Care 

Ground Transportation


To complement its critical care services, CHEMS in 2014 introduced the region's first ground critical care and neonatal intensive care units. These vehicles are equipped with advanced capabilities that are typically found only in hospital emergency departments and intensive care units, allowing us to provide our patients with advanced lifesaving procedures during transport.

Air Transportation


Commonwealth One is an Airbus Eurocopter EC 135 with a twin-engine helicopter capable of flying a 380-mile radius at a cruising speed of 160 miles per hour.

CW1 is stationed at Seaman's Airport, Factoryville, Pa., and serves an 11-county area. The helicopter is supplied and operated by Air Methods, one of the largest community-based providers of air medical services. Air Methods was the first air transportation provider to reach the highest level (Level 4) of the FAA’s voluntary Safety Management System program.
