During robot-assisted laparoscopic prostatectomy, specific physiological conditions such as carbon dioxide insufflation and the steep Trendelenburg position can alter the cardiac workload and cerebral hemodynamics. Inadequate arterial blood pressure is associated with hypoperfusion, organ damage, and poor outcomes. Dynamic arterial elastance (Ea) has been proposed to be a useful index of fluid ...

BACKGROUND Respiratory-induced arterial and plethysmographic (pulse oximetry) waveform changes were shown to be good predictors of cardiac output response to increased preload. The aim of this study was to evaluate the reliability of arterial and plethysmographic waveform variables in patients with mild hypovolemia. METHODS Patients undergoing autologous hemodilution were studied. After anest...

Abstract Background Maximal aerobic capacity, e.g. maximal oxygen uptake (V̇O 2 max), is not constant, and it has a time-dependent variation based on the condition of individual. On other hand, arterial properties play an important role in determining performance, lower stiffness associated with higher cardiorespiratory fitness levels. This study examined whether individual variations performanc...

effects of acute systemic hypoxia on the cardiovascular system (cys) and respiration of spontaneously breathing cats were studied in two conditions. 1): hypoxic air (6-8% 02 in n2) was given to the animal to induce systemic hypoxia for 20 minutes. hyperventilation at this condition lowered arterial c02 tension (pac02 hypocapnia). 2): in the second run, induction of hypocapnia was prevented by a...

base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...
