Anaesthetic monitoring: clinical practice in anaesthetic rooms and theatres.

Twenty anaesthetic rooms and operating theatres in Northern Ireland were visited in both 1990 and 1992. Data was collected on the availability and use of anaesthetic monitoring. In the anaesthetic rooms there were few pulse oximeters. In the theatres more monitors were available and in use. Some change in practice had occurred between 1990 and 1992, notably an increase in the monitoring of ventilation, and in the availability of printer facilities for documentation of anaesthetic records.
