Concurrently,there occurred an enhancement of spectral powerin the frequency components VLF and LF, and a reductionin the spectral power of the HF component.Similar changes were observed in the case of relativespectral powers. There an enhancement in LF/HFratio and decrease of CCVHF parameter occurred.The mentioned changes are related to a highervariability of individual respiratory frequency inthe examined sample during spontaneous respiration(TABLE 1).2.2 Position change from lying to sitting during spontaneousrespiration (TABLE 2)During a position change from lying (interval T4) tositting (interval T5), we found a significant reductionin total spectral power (sitting as a demonstration ofpartial orthostasis). Concurrently, a significant reductionin the spectral power of the frequency componentHF, a reduction in the relative spectral power HF,
