## Abstract

Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient's head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient's head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.

## Claims

### Claim 1

A respiratory treatment system comprising:
a gas distribution system; and
at least one sensor, the at least one sensor capable of detecting at least the position of a patient's head,
wherein said gas distribution system is controlled in part or in whole by direct or indirect response to input from said at least one sensor.

### Claim 2 (depends on 1)

The respiratory treatment system of claim 1, wherein said at least one sensor comprises a camera.

### Claim 3 (depends on 1)

The respiratory treatment system of claim 1, further comprising an oxygen sensor, wherein said gas distribution system is further controlled by said oxygen sensor.

### Claim 4 (depends on 1)

The respiratory treatment system of claim 1, further comprising a blood oximeter, wherein said gas distribution system is further controlled by said blood oximeter.

### Claim 5 (depends on 1)

The respiratory treatment system of claim 1, further comprising a hood capable of at least partially confining gases around said patient.

### Claim 6 (depends on 5)

The respiratory treatment system of claim 5, wherein said gas distribution system comprises at least one gas delivery port, the at least one gas delivery port mounted to said hood.
