When the patients received vascular expansion or when a change in the infusion rate of catecholamines was decided, a 10 min period of stability (<10% changes in cardiac frequency and arterial pressure) was required before the measurements were taken.
Measurements after 45 min of hemodynamic stability in each phase included differential lung perfusion using colored microspheres and differential lung ventilation using the double lumen tube.
Assessment of baseline hemodynamics was initially done before saline infusion after a 20-min period of stability of vital signs, including heart rate (HR).
In this work, we used the integrated random walk process and we set the power spectral density (PSD) of the clock rates process noise to 0.64 ns2/day3, what corresponds to an Allan standard deviation of 10-14 over 50 min (typical stability of an hydrogen maser used at the VLBI stations).
Significant retention of anthocyanin content (>94%) was observed at the maximum treatment conditions of 100% amplitude level for 10 min, indicating stability of anthocyanin during sonication.
With the increasing of stirring time from 30 to 180 min, the stability of as-prepared nanofluids is greatly improved.
Based on a nonconvex Lyapunov function of min type, stability conditions and quantities similar to H2 and H∞ norms are calculated.
Five potential formulations (F1 F5) were designed while F1 and F4 exhibited the most promising results in terms of stability with 26 min and 40.67 min, respectively, and suitability in nail application.
