Jet ventilation (JV) involves high-pressure ventilation for upper laryngeal laser procedures. Anesthetic management for the patient undergoing JV can be challenging, as complications of JV can include subcutaneous emphysema and tension pneumothorax. A 52-year-old woman with a diagnosis of vocal cord polyps presented for direct microlaryngoscopy and laser laryngoplasty with JV. Intraoperatively,...
through these catheters," we recommended in our case report that jet ventilation through these catheters shodd not be necessary during the brief period of tube exchange.' According to the editorial of Benumof,' air entry should not exceed air exit. The incidence of complicating barotrauma may be decreased by selecting a properly sized exchange catheter in proportion to the size of the endotrach...
BACKGROUND High-frequency ventilation can be delivered with either oscillatory ventilation (HFOV) or jet ventilation (HFJV). Traditional clinician biases may limit the range of function of these important ventilation modes. We hypothesized that (1) the jet ventilator can be an accurate monitor of mean airway pressure (P (aw)) during HFOV, and (2) a mathematical relationship can be used to deter...
minimize the risk of barotrauma, the following precautions are recommended. multiple distal side holes also may decrease the pressure delivered at the distal end, minimize the catheter whip, and center the catheter within the trachea during jet ventilation.3 1. The patient must be adequately preoxygenated and hyperventilated by the original endotracheal tube using 100% oxygen. 2. An exchange ca...
BACKGROUND Percutaneous transtracheal ventilation (PTV) via a jet ventilator (PTJV) is considered a rescue technique in difficult airway management. However, whether a conventional ventilator can generate adequate ventilation via PTV is not known. Our goal was to evaluate the tidal volume (V(T)) generated by a conventional ventilator during simulated PTV compared with PTJV in a lung model. ME...
Introduction Acute exacerbations of pulmonary emphysema lead to increased morbidity, mortality and, in some cases, requirement of invasive mechanical ventilation (MV) [1]. So far, no study has compared the biological impact of pressurecontrolled ventilation (PCV) versus pressure-support ventilation (PSV) in experimental emphysema. Our aims were to develop an elastase-induced emphysema model in ...
An approach which promotes a rapid return to spontaneous respiration after tracheobronchial stent (TBS) insertion is considered the optimal one and is a belief shared by anaesthetists, respiratory physicians, and surgeons alike (Calvey and William (2008)). The value of the laryngeal mask airway (LMA), followed by use of the Monsoon 111 Acutronic jet ventilator pressure limiting system of ventil...
