The increase in amplitude of fluctuations of cerebral hemoglobin concentration in respiratory band related to increase in intra-abdominal pressure

We present results of clinical studies in patients during increase in intra-abdominal pressure (IAP). Changes in brain hemoglobin concentration assessed from time-resolved nearinfrared spectroscopy system were analyzed in frequency domain. The amplitude of power spectral density in respiratory band increases while IAP increases what is related to reduced venous outflow.
