INTRODUCTION: In an experimental study on carbon monoxide (CO) exposure in swine, we aimed to compare the influence of oxygen therapy using a non-rebreathing mask (NRM) to continuous positive airway pressure (CPAP) and two pressure support ventilation (PSV) devices on the decrease of the terminal elimination half-life of carboxyhemoglobin (COHb t1/2 ). This was the primary outcome. METHODS: Eight spontaneously breathing pigs were sedated by propofol and exposed to 940 ppm CO several times (n = 25) to obtain COHb levels of 30%...

BACKGROUND: When encountering a difficult airway with an Airway Scope (AWS) a bougie can be inserted into the endotracheal tube in the AWS channel. The angulated tip of the bougie can be guided toward the glottis by rotating it. We tested the ease of rotating bougies (Venn reusable, Boussignac, Portex single-use, and Frova) in an endotracheal tube when placed in the AWS channel. METHODS: Bench study: Seven anesthesiologists inserted each of the four types of bougies into a 7...

AIM OF THE STUDY: The purpose of this study was to examine continuous oxygen insufflation (COI) in a swine model of cardiac arrest. The primary hypothesis was COI during standard CPR (S-CPR) should result in higher intrathoracic pressure (ITP) during chest compression and lower ITP during decompression versus S-CPR alone. These changes with COI were hypothesized to improve hemodynamics. The second hypothesis was that changes in ITP with S-CPR+COI would result in superior hemodynamics compared with active compression decompression (ACD) + impedance threshold device (ITD) CPR, as this method primarily lowers ITP during chest decompression...

STUDY OBJECTIVE: Pathophysiological changes after laparoscopic Roux-en-Y gastric bypass may increase the risk of pulmonary complications in morbidly obese patients. The purpose of the study was to assess the impact of immediate postextubation use of Boussignac continuous positive airway pressure (CPAP) on arterial oxygenation in morbidly obese patients undergoing laparoscopic Roux-en-Y gastric bypass. The hypothesis is that the use of CPAP may improve oxygenation in the postoperative period when compared to Venturi mask...

CPAP (continuous positive airway pressure) is to establish a supraatmosferica pressure throughout the respiratory cycle on which the patient vent spontaneously. Its use improves the clinical and gasometrics parameters when applied with appropriate selection criteria in the context of respiratory failure acute (IRA) hypoxemic. It has been demonstrated that applying CPAP early, decreases the need for intubation and associated complications, as well as survival, reducing health care costs and hospital stay. The use of valve Boussignac for applying a CPAP is spreading especially in the delivered environment and emergencies as a device not mechanical, simple, easy to use and transport, which can manage enough pressures to manage the patient hypoxemia...

BACKGROUND: Acute respiratory failure is a frequent cause of emergency medical missions. Continuous positive airway pressure (CPAP) therapy could be particularly beneficial, avoiding risks associated with intubation and invasive ventilation. Hardly any data exist from Germany on this matter. PATIENTS AND METHODS: CPAP therapy with the Boussignac system as additional measure was introduced in cases of acute cardiogenic pulmonary edema (ACPE) or decompensated chronic obstructive pulmonary disease (COPD) in a physician-supported emergency medical services system (EMS)...

While controlled ventilation is most frequently used during cardiopulmonary resuscitation (CPR), the application of continuous positive airway pressure (CPAP) and passive ventilation of the lung synchronously with chest compressions and decompressions might represent a promising alternative approach. One benefit of CPAP during CPR is the reduction of peak airway pressures and therefore a potential enhancement in haemodynamics. We therefore evaluated the tidal volumes and airway pressures achieved during CPAP-CPR...

BACKGROUND: CPAP is frequently used in prehospital and emergency settings. An air-flow output minimum of 60 L/min and a constant positive pressure are 2 important features for a successful CPAP device. Unlike hospital CPAP devices, which require electricity, CPAP devices for ambulance use need only an oxygen source to function. The aim of the study was to evaluate and compare on a bench model the performance of 3 orofacial mask devices (Ventumask, EasyVent, and Boussignac CPAP system) and 2 helmets (Ventukit and EVE Coulisse) used to apply CPAP in the prehospital setting...

INTRODUCTION: There are some patients with severe respiratory disturbances like adult respiratory distress syndrome (ARDS) and suspicion of brain death, for whom typical performance of the apneic test is difficult to complete because of quick desaturation and rapid deterioration without effective ventilation. To avoid failure of brain death confirmation and possible loss of organ donation another approach to apneic test is needed. We present two cases of patients with clinical symptoms of brain death, with lung pathology (acute lung injury, ARDS, lung embolism and lung infection), in whom apneic tests for recognizing brain death were difficult to perform...

BACKGROUND: Postoperative continuous positive airway pressure (CPAP) can improve lung function. The aim of our study was to assess the efficacy of prophylactic CPAP on the Pa(O2)/FI(O2) ratio measured the day after surgery in patients undergoing lung resection surgery (LRS). METHODS: The study population comprised 110 patients undergoing LRS. On arrival in the postanaesthesia care unit (PACU), patients were randomized to receive CPAP at 5-7 cm H2O during the first 6 h after surgery (CPAP group) or supplemental oxygen through a Venturi mask (Venturi group)...

AIM: High-flow-oxygen-therapy is provided by various techniques and patient interfaces, resulting in various inspired-fraction of oxygen (FiO2) and airway-pressure levels. However, tracheal measurements have never been performed. METHODS: Three oxygen-delivery-devices were evaluated: 1) standard-high-flow-oxygen-facemask with reservoir-bag, 2) Optiflow(TM)-high-flow-nasal-cannulae and 3) Boussignac(TM)-oxygen-therapy-system. Main judgment criteria were airway-pressure and FiO2 measured in the trachea...

BACKGROUND: Early use of continuous positive airway pressure (CPAP) has been shown to be beneficial within the setting of acute cardiogenic pulmonary edema (ACPE). The Boussignac CPAP system (BCPAP) was therefore introduced into the protocols of emergency medical services (EMS) in a large urban region. This study evaluates the implementation, practical use and complications of this prehospital treatment. METHODS: This was a retrospective case series study. The study was carried out in a period shortly after the implementation of the BCPAP system on all EMS ambulances in the The Hague region...

Traditionally, continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BiPAP) devices have been used to treat patients in acute respiratory failure. However they require an electric power source, are relatively large in size, and may be difficult to use in prehospital settings. The recently introduced Boussignac CPAP system is capable of delivering 10 cmH2O of CPAP, is compact, portable and requires only an oxygen source. This paper reviews the efficacy of using Boussignac CPAP as a treatment for acute respiratory failure in both prehospital and hospital settings...

BACKGROUND: The performances of 2 noninvasive CPAP systems (high flow and low flow air-entrainment masks) were compared to the Boussignac valve in 3 different scenarios. METHODS: Scenario 1: pneumatic lung simulator with a tachypnea pattern (tidal volume 800 mL at 40 breaths/min). Scenario 2: Ten healthy subjects studied during tidal breaths and tachypnea. Scenario 3: Twenty ICU subjects enrolled for a noninvasive CPAP session. Differences between set and effective CPAP level and FIO2, as well as the lowest airway pressure and the pressure swing around the imposed CPAP level, were analyzed...
