Explanation:
I've come across this term before in various medical articles and it's commonly used. It can be written either with or without the hyphen (forced-air warming OR forced air warming), but I've always used it with the hyphen

Example sentence(s):
  • Home > Types ofForced-air warming blankets and gowns warm by blowing warm air across the surface of the skin.

heat carried by heated air


Explanation:
this refers to a type of heating system that uses air to carry/spread the heat to the appropriate outlets.

The following from a U.S. heating and air-conditioning company is a useful explanation of the term:

"What Is Forced Air Heating?

Chances are that you’ve heard the term forced air heating before, particularly if you’re in the market for a new home heating system. But what does that actually mean? The truth is that if you’re asking this question, you’re not alone. There are so many types of home heating systems out there that it’s common to be a bit confused and overwhelmed by it all.

The truth is that a forced air heating system is simply a heating system that distributes heat throughout your house using air to carry it. In this type of system, heated air travels through a system of ducts and is expelled through vents into the different rooms and areas of your home in order to maintain a particular temperature. That temperature, of course, is whatever you set your thermostat to, and when the desired temperature is reached, the heat will shut off until the temperature drops down again."

In the medical context, it simply means warmed/heated air being pumped as opposed to direct heat from something like a heating pad.

This from wikipedia is also useful. The equivalent of the "duct system" in this medical example is most probably a distribution system within the blanket.

I had personal experience with such a system post surgery when my body wasn't coming back up to normal temperature as quickly as it should have in the recovery room. I

"A forced-air system is one which uses air as its heat transfer medium. These systems rely on ductwork, vents, and plenums as means of air distribution, separate from the actual heating and air conditioning systems. The return plenum carries the air from several large return grills (vents) to a central air handler for re-heating. The supply plenum directs air from the central unit to the rooms which the system is designed to heat. Regardless of type, all air handlers consist of an air filter, blower, heat exchanger/element/coil, and various controls. Like any other kind of central heating system, thermostats are used to control forced air heating systems.

Forced air heating is probably the type most commonly installed in North America. It is much less common in Europe, where hydronic heating predominates, especially in the form of hot-water radiators."

This is also refered to as convective warming systems, which do use forced air, as opposed to conductive like electric pads, heated gel pads, and heated water bottles.

agree  jccantrell: I think the real term that should be emphasized is 'pumped', i.e., there is a fan that is pumping, or pushing or forcing, the air from the furnace to the 'end user,' as it were.

  -> Thanks. I think they use forced air to contrast it with the direct application of a heated surface like a hot water or an electric heater or a heated gel

neutral  B D Finch: Forced air heating is not the same as convection heating. The latter relies upon the natural tendency of warm air to rise and of cold air to sink.
