Efficacy 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 کاملPreoxygenation: 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...

The Electromyographic Changes of Abdominal Muscles in Two Sit-up Movement for One Minute
ABSTRACT Muscles have an important role in daily physical works and with increasing knowledge of them we could have appropriate physical position and achieving success in sports. The purpose of this research is to study of electromyographic changes of two abdominal muscle (Rectus abdominus and external oblique) in two kinds of sit- up in one minute. The subjects were 15 healthy students and n...
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...
