Airway pressure release ventilation is a recently described method of ventilatory support. It allows spontaneous ventilation with CPAP but differs from conventional ventilatory modes because, with APRV, peak inflation pressure never exceeds the level of CPAP, and airway pressure decreases, rather than increases, when tidal volume is delivered. The risk of pulmonary barotrauma and adverse hemody...

Tracheoesophageal fistulas (TEF) present a perioperative management challenge. A 62 year-old man with esophageal carcinoma presented with a large tracheoesophageal fistula extending most of the trachea. Previously, the patient had two overlapping esophageal and one tracheal stent placed, but he developed progressive tracheal disruption due to esophageal stent perforation near the level of the c...

N Engl J Med 2007;357:e4. Copyright © 2007 Massachusetts Medical Society. Indications Providing positive-pressure ventilation with a face mask and a bag-valve device can be a lifesaving maneuver. Although seemingly simple, the technique requires an understanding of the airway anatomy, the equipment, and the indications. Face-mask ventilation is used in patients who have respiratory failure but ...

BACKGROUND Prompt recognition of the reversal of respiratory failure may permit earlier discontinuation of mechanical ventilation, without harm to the patient. METHODS We conducted a randomized, controlled trial in 300 adult patients receiving mechanical ventilation in medical and coronary intensive care units. In the intervention group, patients underwent daily screening of respiratory funct...

In viral pneumonia, the incidence of subcutaneous emphysema and spontaneous pneumomediastinum are rare. But it can occur due to COVID-19 SARS (severe acute respiratory syndrome) corona infection. this condition like disease underlying pathology may be diffuse alveolar injury. High pressure levels in alveoli cause rupture ultimately forms emphysema. We report one case admitted hospital later dev...

Background High-flow nasal oxygen (HFNO) has been shown to benefit oxygenation, ventilation and upper airway patency in a range of clinical scenarios, however its use in spontaneously breathing patients during general anaesthesia has not been described. Spontaneous respiration using i.v. anaesthesia is the primary technique used at our institution for tubeless airway surgery. We hypothesized th...

Abstract Background Spontaneous pneumomediastinum, pneumothorax and spontaneous subcutaneous emphysema are rare entities. A rising trend in the setting of COVID-19 even patients who not put on invasive ventilation can suggest an alternative aetiology. Case presentation We describe four cases which presented with suspected symptoms were diagnosed pneumothorax, would have been missed if for compu...
