The aim of this study was to determine the mechanism(s) responsible for the persistence of respiratory sinus arrhythmia (RSA) during central apnea. In five awake dogs, heart rate (HR) was recorded during constant mechanical ventilation (MV) and during central apneas produced by cessation of MV. For each of 10 control ventilator cycles before MV was stopped, instantaneous HR was plotted against ...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

OBJECTIVES Although pediatric intensivists philosophically embrace lung protective ventilation for acute lung injury and acute respiratory distress syndrome, we hypothesized that ventilator management varies. We assessed ventilator management by evaluating changes to ventilator settings in response to blood gases, pulse oximetry, or end-tidal CO2. We also assessed the potential impact that a pe...

Active robotic filtering is a promising solution for beating heart Totally Endoscopic Coronary Artery Bypass Grafting (TECABG). n this work, we assess the heart motion dynamics using simultaneously igh speed imaging of optical markers attached to the heart, ECG signals and ventilator airflow acquisitions. Our goal is to make an assessment of the heart motion (shape, velocity, acceleration) in o...
