Understanding Factors That Influence Electronic Cigarette Nicotine Delivery Through PET Imaging of Beta-2 Nicotinic Acetylcholine Receptors

The goal of this proposal is to test the overall hypothesis that e-cigarettes (ECs) provide efficient nicotine delivery to the brain and arterial blood in non-EC-nave smokers and e-cigarette users and that EC liquid characteristics modulate this effect. This study will test the hypothesis through complementary methods that include [ …

Driving Pressure in Neurosurgery

The effect of driving pressure (DP)-guided positive end expiratory pressure (PEEP) on early postoperative pulmonary ventilation is to be determined for patients undergoing neurosurgery. Patients are recruited to receive volume controlled ventilation with either a fixed PEEP (5cmH2O) or DP titrated PEEP. Early postoperative regional distribution of lung ventilation, expressed …
