A protection device for hand held ultrasound needle procedures that can be generally described as a shield attachable to a transducer. The shield protects the hand from needle puncture. The shield can be made from either a flexible or a rigid material which is resistant to needle punctures, by both or either a hand directed needle or a mechanically fired needle. The shield is bent in the shape of an arc. The arc has a first apex at the top of the arc. A second apex is located at the bottom of the arc. A first receiver and a first method of securing an upper end of a transducer, or cable attached thereto, is located at the first apex. A second receiver and a second method of securement is located at the second apex to receive and secure a lower end or head of a transducer to the shield. The device attaches above or over a biopsy guide typically located on the head of a transducer or it attaches directly to the transducer. It allows the technologist to grasp the transducer within the arc of the shield and use the transducer in a normal manner while providing a barrier between the directed biopsy needle and the technologist's or physician's hand. The receiver and method of securement can be as simple as an opening with hook and loop material or as elaborate as specialty latches designed to specifically attach to the transducer.

The airway valve system of claim 1, further including an alarm device responsive to the actuation pressure being outside of a selected range of magnitudes. 17. The airway valve system of claim 1, further including an alarm device responsive to the actuation pressure being above a first selected magnitude when the airway valve is in the first mode and responsive to the actuation pressure being below a second selected magnitude when the airway valve is in the second mode. 18. The airway valve system of claim 1, further including an alarm device responsive to a selected number of deviations of the actuation pressure from a selected pressure magnitude. 19. The airway valve system of claim 18, wherein the alarm device is responsive to an occurrence of the selected number of deviations within a selected period of time. 20. The airway valve system of claim 18, wherein the alarm device is responsive to an occurrence of the selected number of deviations if each of such deviation is of at least a selected magnitude with respect to the selected pressure magnitude. 21. The airway valve system of claim 1, further including an air flow sensor, a CO2sensor and, a processor for computing inspired CO2volume responsive to signals from the air flow sensor and the CO2sensor and circuitry for triggering an alarm responsive to deviation of a computed inspired CO2volume from a selected magnitude or range of magnitudes. 22. The airway valve system of claim 21, wherein the air flow sensor and the CO2sensor are combined into a single unit. 23. The airway valve system of claim 1, further including a CO2sensor located to detect CO2in the breathing circuit between the airway valve and a patient and a processor for computing at least one of end-tidal or end-inspired CO2concentration responsive to signals from the CO2sensor and operably coupled with circuitry for triggering an alarm responsive to deviation of at least one computed CO2concentration from a selected magnitude or range of magnitudes. 19910800, Pouchot et al.; US-5125402, 19920600, Greenough; US-5303701, 19940400, Heins et al.; US-5372130, 19941200, Stern et al., 128/205.25; US-5579761, 19961200, Yuschak et al., 128/201.25; US-5676133, 19971000, Hickle et al., 128/202.27; US-5788215, 19980800, Ryan, 251/149.6; US-5906203, 19990500, Klockseth et al.; US-5924420, 19990700, Reischel et al., 128/206.17; US-6016804, 20000100, Gleason et al., 128/205.25
