On the Possibility of Indirect Respiratory Rate Monitoring
Respiratory parameters are of great interest in neurosurgical intensive care. But in practice continuous monitoring of these parameters for long periods of time is very difficult. At first sight it looks rather simple to measure at least respiratory rate continuously, but all known methods, like thermistor probe registration or electrical chest impedance plethysmography produce many artifacts or are poorly tolerated by the patients. We obtained a higher reliability and more comfort for the patients and nurses by developing new methods using the ballistorespirogram (BRG) and the central venous pressure (CVP) by an indirect measurement.
