Automation of Cardiopulmonary Bypass Data Collection
Abstract
A computer assisted data collection system is presented. The system is comprised of a microprocessor with permanent memory, a general purpose interface board capable of analog to digital conversion, and communication ports to collect data from other microprocessors. Continuous in-line blood gas values and ventilation control parameter values are passed to the microprocessor for storage in an addressable memory location. Analog signals for blood flow, patient temperatures and pressures are also stored and referenced to real time. This system provides the perfusionist with the following capabilities in the in vivo laboratory and OH surgical suite; minute-by-minute trending of the progress of perfusion, documentation of device and perfusionist performance and patient response to dynamic changes. Physiological transformations and calculations are automatically performed and the microprocessor notifies the perfusionist of user defined alarm situations. Analysis of the data base created on-line by this system leads to learning situations that improve open heart surgical teamwork, the consistency of patient care, and provides a possible defense against medical legal complication.
