摘要:

A microcomputer system for the measurement of parameters of ventilation and blood pressure in the spontaneously breathing anaesthetized patient is described. The system continuously calculates minute volume, respiratory frequency, and mean end tidal carbon dioxide concentration. Additionally four cardiovascular parameters are measured. The inputs are obtained from a wet-wedge spirometer, a capnograph and a blood pressure monitor. The methods of computer calculation are described in detail. The computer-generated results are compared with those obtained by manual calculation. The system described has the capacity to record and display a wide variety of further measurements made during anaesthesia. This system provides invaluable information for research and teaching, but may also be useful during routine anaesthesia.

摘要:

A new radiotelemetry receiver type 7060 for use with radiopills is described. Its performance under laboratory conditions was assessed and its use for clinical colonic pressure measurements evaluated. The receiver, which resembles a small microcomputer, was easy to set up and worked reasonably well under ward conditions. Difficulties were experienced with the belt aerial supplied with the receiver, which did not reliably pick up signals from a freely moving radiopill. The receiver is not suitable for ambulatory applications. Its main clinical use is in situations where frequent sampling of the radiopill's signal over a long period of time is essential (e.g. colonic pressures). The large quantity of data generated can be fed from the receiver's analogue or digital output on line to a recorder.
