Abstract: An atmosphere sampling system includes: an unmanned rotary-wing aircraft platform including: an airframe capable of lifting a selected payload mass; at least one motorized rotor; and, a flight control system including an on-board controller; an atmosphere sampling unit having a total mass no greater than the selected payload mass, and including: a blower preferably having backward-facing blades, an inlet structure to draw in air to be sampled, and an outlet to discharge air after sampling; a plurality of sample containers; and, an indexing mechanism to move selected sample containers, one at a time, into contact with the inlet structure so that samples may be collected; and, a power supply with sufficient capacity to operate the motorized rotor(s), the onboard portion of the flight controller, the blower, and the indexing system.

Abstract: A system for flushing carbon dioxide from ventilation equipment so that the carbon dioxide is not rebreathed by the patient. Flushing is achieved by providing tracheal gas insufflation only during the end of the patient's expiratory phase.
