BACKGROUND Perfusion index (PI) is a non-invasive numerical value of peripheral perfusion obtained from a pulse oximeter. In this study, we evaluated the efficacy of PI for detecting haemodynamic stress responses to insertion of i-gel, laryngeal mask airway (LMA) and endotracheal tube and compare, its reliability with the conventional haemodynamic criteria(More)
In the present article, kinetics of the clustering processes in AF/C489 Alloyin the early stages of aging was probably contributed by coalescence of Cu-vacancy, Li-vacancy and Zn-vacancy complexes to form Li–Cu-Zn-vacancy clusters. The high value of the activation energy indicate that the driving force of the clustering process is high. In Li-containing(More)
