Pressure volume parameters for optimal function of an intraaortic balloon without a pump (Journal article)
Sideris, D. A./ Chrysos, D. N./ Pras, A./ Michalis, L. K./ Maliaras, G. K./ Moulopoulos, S. D.
An air filled intraaortic balloon connected to an extravascular air chamber (compression chamber system-CCS) was used in 10 anesthetized dogs to increase its stroke volume (SV). Highest SV increases (up to over 200%) were observed at low SV states, with a high CCS volume and with high increases of the systolic pressure. The CCS pressure--systolic pressure relationship was a sigmoid-like curve. In conclusion, highest SV's may be achieved at low SV states, using CCS volumes about 400 ml and the highest CCS pressure that may cause a linear aortic pressure increase.
