Novel gas mixture combined with an auto-transfusion tourniquet enhances cerebral O transport and hemodynamic indices in CPR swine. Part B - A pilot experimental study.

Objectives: The cognitive outcome of CPR is poor. This study aims to evaluate if enhancing blood flow to the brain and oxygen dissociation from the hemoglobin improve cerebral O transport during CPR in cardiac arrest swine.

Methods: Standard swine-CPR model of induced VF and recovery was treated with an auto-transfusion tourniquet (A-TT®; HemaShock® (HS) Oneg HaKarmel Ltd.

"Open lung ventilation optimizes pulmonary function during lung surgery".

Background: We evaluated an "open lung" ventilation (OV) strategy using low tidal volumes, low respiratory rate, low FiO2, and high continuous positive airway pressure in patients undergoing major lung resections.

Materials And Methods: In this phase I pilot study, twelve consecutive patients were anesthetized using conventional ventilator settings (CV) and then OV strategy during which oxygenation and lung compliance were noted. Subsequently, a lung resection was performed.

Effects of diameter, length, and circuit pressure on sound conductance through endotracheal tubes.

We evaluated the acoustic frequency response of endotracheal tubes (ETs) to assess their effect on respiratory system sound transmission studies. White noise 150-3300 Hz was introduced into 4.0-, 6.
