The original meaning of the term 'Ambulance' is a moving hospital. In McComb, the most common ambulance service is the patient-transport ambulance, where the vehicles are not usually equipped with life-support equipment, and are usually crewed by staff with fewer qualifications than the crew of emergency ambulance services .It only transfers a patient to and from or between places of treatment. Ambulance services in McComb are often associated with on-road emergency services, which form part of a medical service, giving preliminary treatment to those with acute medical problems.
In McComb, ambulance services are provided anytime, in any condition and operate in all weather conditions. Even if there is a crisis situation, as in situations where civilian drivers often opt to stay off the road, such services would be available 24*7. The services may be provided by local or national government, even organizations, hospitals or by local municipalities or provincial health agencies. Charities or non-profit companies operate ambulance services, both in an emergency and as a patient-transport function. In some cases, charitable organizations may employ volunteers to operate a full time ambulance service. Private companies may provide only the patient-transport elements of ambulance services, but in some places, they are contracted to provide emergency care also. The main feature is that all personnel who provide the services are at least trained in ambulance services. The levels of qualification that the ambulance service crew may hold, is from holding no formal qualification to having a fully qualified doctor on board.
