For the purpose of covering at least the head of a person lying on a person supporting device such as a hospital bed or gurney, a unit having a hood is provided. The unit is particularly a mobile unit so that the unit can be easily put in place relative to a person supporting device or moved away from a person supporting device and taken to another area. The hood has a generally dome-shaped appearance and can be put in an expanded state and in a collapsed state according to desire. The hood is supported on a floor surface through a frame. Preferably, the unit is configured to enable adjustment of a height position of the hood relative to the floor surface. The hood provides privacy to a person and shields the person from external stimuli.

Described herein is a breath training apparatus [100], comprising a breathing unit [102], a CO.sub.2 modulation unit [106, 108], and a control unit [112]. The breathing unit [102] has an enrichment airflow pathway [102c], and is adapted to provide inhalation air with enriched CO.sub.2 concentration. The control unit [112] comprises a CO.sub.2 actuator [112a, 112b], a CO.sub.2 sensor [112d], and a controller [112g]. The controller: receives the signals corresponding to CO.sub.2 concentration within the enrichment airflow pathway [102c] from the CO.sub.2 sensor [112d], compares the CO.sub.2 concentration with a defined CO.sub.2 concentration; and correspondingly controls the CO.sub.2 actuator [112a, 112b] for controlled manipulation of the CO.sub.2 modulation unit [106, 108], such that the controlled manipulation of the at least one CO.sub.2 modulation unit [106, 108] adjust the CO.sub.2 concentration within the enrichment airflow pathway [102c] at least substantially equivalent to the defined CO.sub.2 concentration.

A negative pressure respiratory treatment hood for human medical patients. A rigid hood, preferably of unitary fabrication from a clear material, is positioned over the patient's head. The patient's body extends out of an opening in a front wall of the hood. A hinged door may be attached to the front wall of the hood, and is closed and partially closes the opening, and a shroud is sealing connected to the hood and is draped over the patient so as to form a pressure seal. A negative pressure source is connected to the hood and forms a negative pressure environment around the patient's head. Access openings have a resilient material across them, with small openings in the resilient material, to permit access to the patient by medical personnel and/or medical equipment.
