Aim. The aim of this investigation was to examine the alterations in the peritoneum after cold dry CO2, heated dry CO2, and humidified heated CO2 at pressures equivalent to intraperitoneal pressures used in human laparoscopy. Methods. Eighteen rats were divided into 4 treatment groups-group 1: untreated control; group 2: insufflation with cold dry CO2; group 3: insufflation with heated, dry CO2...

Demand oxygen systems have been shown to be effective in treating hypoxemia during seated rest and during exercise, but the performance of these systems during sleep has not been previously studied. We compared the efficacy of a new demand oxygen saver system with that of continuous flow nasal oxygen during the usual activities of daily life including sleep, seated rest, and exercise. Six hypox...

INTRODUCTION Use of submicrometer particles combined with condensational growth techniques has been proposed to reduce drug losses within components of high-flow nasal cannula therapy systems and to enhance the dose reaching the lower respiratory tract. These methods have been evaluated using continuous inhalation flow rather than realistic inhalation/exhalation breathing cycles. The goal of th...

An oxygen-enriched atmosphere enhances the potential for operating-room fires. We thus determined oxygen concentrations at various facial landmarks during oxygen administration via nasal cannulae. Thirteen supine volunteers were draped similarly to patients undergoing a cervical-node biopsy. Oxygen was delivered in random order through nasal cannulae at rates of 2, 4, and 6 l x min(-1). Oxygen ...

OBJECTIVE Heated and humidified high flow nasal cannula oxygen therapy (HFNC) represents a new alternative to conventional oxygen therapy that has not been evaluated in the emergency department (ED). We aimed to study its feasibility and efficacy in patients exhibiting acute respiratory failure presenting to the ED. METHODS Prospective, observational study in a university hospital's ED. Pati...

ABSTRACT Objective To demonstrate that heated humidified high-flow nasal cannula (HHHFNC) is superior to inhaled hypertonic saline solution (HSS) in improving respiratory distress in moderate bronchiolitis. In addition, it could improve comfort and reduce length of hospital stay (LOS) and admissi...

Abstract The perioperative anaesthetic management of a case COVID-19 pneumonia with multiple systemic comorbidities, posted for unilateral below knee amputation and debridement hand, poses uniquely challenging scenario the anaesthesiologist. We hereby report such which was managed successfully using ultrasound-guided popliteal wrist block along use high flow nasal cannula, incentive spirometry ...

BACKGROUND The fraction of inspired oxygen (F(IO(2))) is quoted for different oxygen delivery systems, but variations in inspiratory flow and tidal volume make precise measurement difficult. We developed a reliable method of measuring the effective F(IO(2)) in patients receiving supplemental oxygen. METHODS Ten subjects with chronic hypoxemia breathed through a mouthpiece with a sampling prob...
