Paramedics
Paramedics are mobile emergency personnel tasked in providing on-site treatment of injuries, as well as transport to the hospital. In the Grand Theft Auto series, paramedics, like the police and fire department, are a form of pedestrian that tend to respond to multiple pedestrian killings, providing every game in the series with a certain degree of realism as well as comedic effect.
Behavior
In-game, paramedics usually appear after three or more pedestrians, either civilians or those of civil services, are killed by either the player or other NPCs. They arrive in groups of two in Ambulances (or the Medicar in Grand Theft Auto 2), and will attempt to revive the killed, with varying success; if the pedestrian is not mutilated by explosions or severe gunshot wounds, paramedics can revive the pedestrian. Once all victims are attended to, the paramedics will depart. In Grand Theft Auto IV, paramedics may appear in both single player, as well as multiplayer.
With the exception of Grand Theft Auto IV, such revivals will completely heal a pedestrian to full health (pedestrians that previously wield a weapon will not regain it after revival). In GTA IV, only pedestrians that are still alive but severely injured (slumped on the floor but still moving, or limping) can be treated with limited success as paramedics are unable to revive dead pedestrian.
In single player in GTA IV, it is possible to call for a paramedic using the player's mobile phone by dialing 911, and selecting "2" after to request for two paramedics in an Ambulance to arrive and treat wounds of the player or non-player characters at a cost. If no one is available for treatment upon their arrival, the paramedics will simply believe they received a prank call and leave.
Design
Paramedics are commonly depicted as medical workers dressed in medical uniforms (basically a shirt, pants and rubber medical gloves, with the optional jacket) and portable medical equipment adapted for use outside hospitals, and are usually depicted dressed in blue, green or white. Upon arrival, most paramedics will utter dialog relevant to their job, primarily providing encouragement to the wounded; unusually, in Grand Theft Auto III, paramedics are also known to sing lines of songs from Flashback FM.
