## Background
BACKGROUND
The present disclosure is related to systems and methods for delivering services, energy, and data within a hospital room. More specifically, the present disclosure is related to a modular architectural room system for delivering gases, electrical energy, and data to a hospital room and an associated method of configuring and assembling the modular architectural room system.
Clinical care settings, such as a hospital room, for example, serve a two-fold purpose of delivering healthcare services. In the first instance, the hospital room serves as an area for delivery of medical care. In the second instance, the hospital room serves as a residence for a recuperating patient.
With regard to the delivery of healthcare services, the hospital room must include state of the art technology accessible to the healthcare provider during the delivery of care. As the acuity of a patient's illness or injury increases, the complexity of additional equipment required to assist with the delivery of care increases. The vital signs of a patient are taken on a regular basis. In a critical care/intensive care unit, other monitoring equipment and service delivery equipment is required. For example, vital signs monitoring may be required in conjunction with ventilation equipment. Generally, the support for the equipment is positioned at the head end of the bed in an architectural headwall unit. For example, gases such as oxygen and compressed air may be delivered to the patient room. A vacuum line may also be provided. Electrical service outlets may also be provided with certain devices being connected to power circuits including emergency back-up for critical devices. The architectural headwall units may also provide central lighting controls and may be configured to provide support for healthcare equipment such as monitoring devices and fluid collection canisters.
The delivery of gases and power and the support of healthcare equipment tend to cause the headwall area of a patient room to appear more clinically oriented than residential. In order to provide a more aesthetically pleasing environment for recuperation, hospitals are known to utilize structures within the room constructed employing wood grains and configured with gas and electrical outlets.
