PPV reflects the respiratory-induced changes in pulse pressure, and is calculated as the difference between the maximum and minimum pulse pressure values during one mechanical breath divided by their mean [ 33, 36].
Freezing the arterial pressure tracing, and measuring systolic and diastolic pressures beat by beat to identify the maximum and minimum pulse pressure values over a single respiratory cycle is a real but time-consuming alternative to the automatic calculation of PPV.
This fact, in turns, generates an additional hydrogen permeation resistance, which diminishes the permeation flux and introduces a threshold in the minimum trans-membrane pressure value required for a hydrogen permeate flux.

The haemodynamic changes produced during the barbiturate coma are presented in Table 5. Differences of note include the minimum MAP, the pulmonary wedge pressure value, and the maximum norepinephrine dosage on days 2 and 3. aCardiac output, cardiac index, peripheral venous resistance and pulmonary artery wedge pressure: the values are the mean values over 24 hours.
The refinement of objective space leads to a fast selection from optimal solutions and finally the selected optimal solution improves the cubage coefficient and the absolute value with the minimum pressure coefficient through a small penalty in the located position of minimum pressure coefficient.
The algometer score will be calculated as the sum of the minimum pain-pressure values obtained for each tender point.
The minimum pressure associated with the typhoon was a value of 957.0 hPa at Basco, where winds exceeding 75 mph (120 km/h) were also recorded.
This pressure value of 0.3 was the minimum pressure reported by Bureau et al. (2007), and the experimental pressure may actually have been higher.
The largest minimum pressure coefficients for these tappings are approximately 20% less in magnitude than the corresponding full-scale values.
