Computer Systems in Artificial Ventilations (New Techniques)
Computer monitoring, surveillance, and therapy of artificially ventilated patients requires a quantity and quality of machine-configuration (e. g., on-line real-time data processing and multidirectional data traffic) which are not available today. Earlier hopes for the machine-controlled respiratory-controlled respiratory-therapeutic loop — although software, hardware and peripheral monitoring devices are developing rapidly — must remain a dream. In 1975, Baum et al. presented a concept that also could not be realized. One of the unfulfilled needs for this concept was exact on-line monitoring of arterial oxygenation and CO2 elimination. Furthermore, end-expiratory CO2 levels are not applicable as primary parameters for respirator settings because of secondary influences from pulmonary perfusion and metabolic state. A computer that initiated the respiratory regimen on the respirator would therefore lack basic data and would remain widely disorientated (Fig. 1).
