of heart-beats, measured in beats per minute. During a certain number of events (e.g. ten heart-beats or more), clock pulses appearing during this period are counted. Their repetition frequency is preselected and known. The measurement interval is calculated from the number of clock pulses ...
Heart rate and blood pressure response to stimulation of the carotid sinus decreased with increasing resting mean arterial pressure. The results suggest impairment of adjustments, via arterial baroreceptor, possibly in particular to dynamic stimuli, rather than via intrathoracic "low pressure" baroreceptor...
prediction and calculation of optimal cerebral perfusion pressure (CPPopt) in 307 patients after severe traumatic brain injury (TBI) based on cerebrovascular reactivity calculation of a moving correlation correlation coefficient, named PRx, between mean arterial pressure (ABP) and intracranial pressure (...
The threshold (Thr) and saturation (Sat) values for the baroreflex are commonly defined as the values of mean arterial pressure (MAP) at which the reflexly controlled variable (e.g., heart rate or sympathetic nerve activity) is within 5% of the upper or lower plateau, respectively, of the...
There is no consensus regarding the method for the calculation of the T:P ratio. We assessed the influences of curve smoothing, the average fall in 24-h mean arterial pressure (MAP) and the length of the peak effect period on the result of T:P ratio calculation. Forty-two patients with...
Consistent with this interpretation, the authors clearly state that both systemic and pulmonary arterial mean pressures decreased significantly after iloprost compared with NO (Table 1). It would be interesting to see to what extent the ratios of pulmonary/systemic blood pressure and the ratios of ...
