Effects of high arterial oxygen tension on function, blood flow distribution, and metabolism in ischemic myocardium.
BACKGROUND Although oxygen inhalation therapy has long been used in the treatment of acute myocardial ischemia, experimental evidence that increased arterial PO2 has any beneficial effect in the absence of hypoxemia is equivocal. In this study, we used a swine model of subendocardial myocardial ischemia to determine the effects of arterial hyperoxia on regional myocardial contractile function (...
متن کاملSingle arterial puncture vs arterial cannula for arterial gas analysis after exercise. Change in arterial oxygen tension over time.
In an attempt to find the least invasive, safest, easiest, and cheapest method of obtaining resting and exercise samples of arterial blood, a comparison was made between samples from an arterial needle puncture and an arterial cannula. This study demonstrated that samples of arterial blood may be obtained by radial arterial puncture both at rest and during exercise in practically all cases with...
متن کاملDemystifying high-lateral-tension abdominoplasty.
The author clarifies "high-lateral-tension abdominoplasty" (HLT), a procedure based on the premise that the greatest abdominal excess is usually in the lateral abdomen and that tightening of lateral excess is what most improves contour the central abdomen. While the classic approach improves contour by pulling inferiorly on the central abdomen, thereby creating the highest tension along the cen...
متن کاملMaternal arterial oxygen tension during intermittent inhalation analgesia.
In mothers nursed in a semi-recumbent position, arterial oxygen tension was measured at the beginning and END OF AN an intermittent period of inhalation, Lasting for six contractions, during the first stage of labour. Ten mothers had methoxyflurane 0.35 per cent and air, followed by methoxyflurane 0.35 per cent with approximately 50 per cent oxygen. Another 10 mothers had 50 per cent nitrous ox...
متن کاملThe normal alveolar-arterial oxygen-tension gradient in man.
2. The gradient increased with age and with inspired O2 concentration up to 60%. Above 60%, during normal breathing, there was no significant change in gradient. 3. Breathing 100% 0, in deep breaths decreased the gradient in all age-groups, significantly so in subjects of 50 years and younger. The remaining gradient was due to anatomical venous shunt. 4. When this anatomical shunt was allowed f...
