Preoxygenation: comparison of maximal breathing and tidal volume techniques.
To the Editor;-Baraka et al. recently demonstrated that preoxygenation using eight deep breaths within 60 s (8 DB/60 s) at an oxygen flow of 10 L/min can produce arterial oxygen tension (PaO2) values comparable to those obtained using normal tidal volume breathing (TVB) for 3 min. In addition, they showed that this technique significantly dekdyed the onset of apnea-induced hemoglobin desaturati...
متن کاملVital capacity and tidal volume preoxygenation with a mouthpiece.
We have measured oxygen wash-in in 20 volunteers undergoing preoxygenation with a face mask, mouthpiece alone and a mouthpiece with a noseclip, in a crossover study. Tidal volume breathing and maximal deep breath techniques were studied with each type of equipment. When tidal volume breathing was used, the face mask and mouthpiece with noseclip were comparable, but the mouthpiece alone achieved...
متن کاملPreoxygenation of patients for coronary artery bypass grafting: vital capacity versus tidal breathing.
Arterial oxygenation, as measured by serial arterial blood gases (ABGs) and in vivo polarographic PaO2 during the rapid sequence induction of general endotracheal anesthesia, was evaluated in 20 ASA physical class IV subjects undergoing elective coronary artery bypass grafting (CABG). Subjects received a narcotic premedication 30-60 minutes prior to arrival in the operating room. Subjects in Gr...
متن کاملEfficacy of preoxygenation using tidal volume and deep breathing techniques with and without prior maximal exhalation.
PURPOSE We evaluated the influence of prior maximal exhalation on preoxygenation in 15 adult volunteers using tidal volume breathing (TVB) for five minutes and deep breathing (DB) for two minutes with and without prior maximal exhalation. METHODS Inspired and end-tidal oxygen, nitrogen and carbon dioxide were monitored continuously and recorded during room air breathing and at 30-sec interval...
متن کاملTotal oxygen uptake with two maximal breathing techniques and the tidal volume breathing technique: a physiologic study of preoxygenation.
BACKGROUND Three common methods for preoxygenation are 3 min of tidal breathing, four deep breaths taken within 30 s (4DB), and eight deep breaths taken within 60 s (8DB). This report compares these three techniques in healthy volunteers. METHODS Five healthy subjects breathed through a mouthpiece and wore a nose clip; oxygen was delivered at 180 l/min via a low-resistance T-piece. Each subje...
