  • BACKGROUND: /st> Existing methods allow prediction of Pa(O(2)) during adjustment of Fi(O(2)). However, these are cumbersome and lack sufficient accuracy for use in the clinical setting. The present studies aim to extend the validity of a novel formula designed to predict Pa(O(2)) during adjustmen

  • OBJECTIVE: Cardiac surgery through a thoracotomy using one-lung ventilation (OLV) is thought to be associated with worse postoperative pulmonary gas exchange than sternotomy using two-lung ventilation (TLV), but this has not been confirmed yet. We, therefore, compared postoperative pulmonary gas exc

  • Jpn J Appl Phys 50(9), 09NC11-09NC11-4, 2011-09-25
  • … We clarified two factors promoting the Sn2+ substitution: the sintering partial pressure of oxygen ($p$O<sub>2</sub>) and the lattice size of BaTiO<sub>3</sub>. … We found the optimum region of sintering $p$O<sub>2</sub>, where a high tetragonality and a high temperature of transition from the ferroelectric phase to the paraelectric phase are realized. …

For example, the necessary amount of oxygen for human respiration, and the amount that is toxic, is set by the partial pressure of oxygen alone. This is true across a very wide range of different concentrations of oxygen present in various ...
