The training headwall is a self-contained unit that delivers air and vacuum to medical gas outlets. Each training headwall contains a minimum of two motors, one a compressor to provide simulated gas flow, and the other a vacuum pump to provide a vacuum run off of electricity supplied from a standard electrical outlet. Because the training headwalls are not used on actual patients there is no need to deliver actual medical gases. Instead, the compressor pumps air to medical gas outlets that are labeled as desired, and may be attached to the appropriate secondary medical equipment, while the vacuum delivers a vacuum to the appropriately labeled gas outlet. Students may use the training headwall to practice patient care procedures.
