Claims
- 1. A resuscitator device for supplying gas to a patient, comprising:
- a regulator providing a main passageway to said patient;
- an exhaust housing in fluid communication with said regulator, said housing having an exhaust port end and a regulator end, said regulator end adjacent said regulator, said exhaust port exhausting into ambient air, said exhaust port including at least a portion which is transparent; and
- a carbon dioxide indicator mounted in said exhaust port at a position viewable through said transparent portion where said indicator leaves an unimpeded pathway for gas through said exhaust port.
- 2. The device of claim 1 wherein said exhaust port includes a PEEP port, said carbon dioxide indicator being mounted in said PEEP port.
- 3. The device of claim 1 wherein said carbon dioxide indicator is embedded on paper.
- 4. The device of claim 1 wherein said regulator is configured to isolate said exhaust port from fresh gases from said regulator, and further comprising a diverting passageway between said regulator and said exhaust port to divert a fraction of said fresh gases to said exhaust port to clear said carbon dioxide indicator.
- 5. The device of claim 4 wherein said fraction of fresh gases diverted is 50% or less.
- 6. The device of claim 4 wherein said diverting passageway comprises a hole in a wall of said main passageway.
- 7. The device of claim 1 further comprising a one-way valve mounted in said exhaust port.
- 8. The device of claim 7 wherein said one-way valve comprises a flexible flap fastened to the center of a frame mounted in said exhaust port.
- 9. The device of claim 1 further comprising a cylindrical desiccant mounted along a center axis of said exhaust housing.
- 10. The device of claim 1 wherein said exhaust housing comprises a PEEP port.
- 11. A method for providing a breath-to-breath indication of carbon dioxide detection in a resuscitator, comprising the steps of:
- providing a regulator, and an exhaust port housing in fluid communication with said regulator, said housing having an exhaust port end and a regulator end, said regulator end adjacent said regulator, said exhaust port exhausting into ambient air;
- inserting a carbon dioxide indicator into said exhaust port where said indicator leaves an unimpeded pathway for gas through said exhaust port; and
- sealing said carbon dioxide indicator from ambient light and moisture.
