Warming system with sensor

1. An air hose comprising:

a corrugated flexible hose;

a first hose end section mechanically coupled to the corrugated flexible hose, the first hose end section comprising a pressure sensor communicatively coupled to a warming unit, the first hose end section is configured to releasably couple to a pneumatic convective device,

wherein the first hose end section has an outside surface facing an environment and an inside surface facing an airflow path, the first hose end section comprises a

static pressure region adjacent to the inside surface, the pressure sensor being disposed within the static pressure region wherein the static pressure region comprises a cavity,

wherein the first hose end section comprises a first end part and a second end part, the first end part is configured to releasably attach to the pneumatic convective device, the second end part is configured to attach to the corrugated flexible hose at one end such that a pneumatic seal is formed between the corrugated flexible hose and the second end part;

and wherein the second end part comprises the cavity, wherein the second end part comprises an inner wall and an outer wall, wherein a space between the inner wall and the outer wall forms the cavity; and

a second hose end section mechanically coupled to the corrugated flexible hose, the second hose end section is configured to couple to the warming unit.

2. The air hose of claim 1 , further comprising an inlet temperature sensor and an outlet temperature sensor.

3. The air hose of claim 1 , wherein the inside surface surrounds at least a portion of the airflow path.

4. The air hose of claim 1 , wherein the first end part and the second end part are attached such that the first end part is rotatable about a longitudinal axis relative to the second end part.

5. The air hose of claim 1 , wherein the static pressure region is a region of the first hose end section that isolates static pressure from the airflow path.

6. The air hose of claim 1 , wherein an airflow path is longitudinal with the corrugated flexible hose and the first hose end section and the cavity is offset from the airflow path.

7. The air hose of claim 1 , wherein the cavity is formed around at least half of an inner perimeter of the first hose end section.

8. The air hose of claim 1 , wherein a distance between the inner wall and the outer wall is between 30 and 40 thousandths of an inch.

9. The air hose of claim 1 , wherein the cavity forms an annulus that allows air from the airflow path to enter.

10. The air hose of claim 1 , wherein the inner wall and the outer wall forms a first opening between an end of the inner wall and a recessed portion of the outer wall that allows air from the airflow path to enter.

11. The air hose of claim 1 , wherein the first end part comprises a lip proximate an end of the first end part.

12. The air hose of claim 11 , wherein the outer wall of the second end part comprises a recessed portion configured to mate with the lip such that the second end part is rotatable relative the first end part.

13. The air hose of claim 1 , wherein the second end part and the first end part, when combined, form the cavity.

14. The air hose of claim 13 , wherein a portion of a wall of the first end part and a portion of an outer wall of the second end part form the cavity.

15. A system, comprising:

the air hose of claim 1 ;

a warming unit that can provide a stream of pressurized, heated air, comprising:

a heater control circuitry; and

a power conversion apparatus for converting Alternating Current (AC) power for use by the heater control circuitry.
