A second level of PEEP (high level PEEP: 20 +/- 4 cm H2O) produced a sharp decrease in CT and required hemodynamic support in each case (blood volume expansion with or without Dopamine infusion) to maintain cardiac index within a normal range. In Group 1 this high level PEEP produced ...
MATERIALS AND METHODS ~~~i~~~were conducted on 14 fetal goats with a mean gestational age of 131 days (0.87 of full term) and a range of 117-150 days. Nannies were anesthetized with chloralose, the fetus exteriorized, and a closed tracheal cannula secured before any ventilation. Catheter...
MethodsOne hundred American Society of Anesthesiologists physical statusⅠor Ⅱ patients of both sexes, aged 1-6 yr, with body mass index in the normal range, scheduled for elective non-abdominal surgery, were divided into no PEEP group (group C, n=50) and PEEP group (group P, n=50) us...
Influence of Respiratory Behavior on Ventilation, Respiratory Work and Intrinsic PEEP during Noninvasive Nasal Pressure Support Ventilation in Normal Subjects Dominique,Vanpee,Charbel,... - 《Respiration》 被引量: 5发表: 2002年 Effect of Nasal Pressure Support Ventilation and External PEEP on ...
Protective intraoperative mechanical ventilation has been associated with reduced incidence of postoperative pulmonary complications.8,9 Among normal weight and overweight patients, low tidal volumes and low levels of positive end-expiratory pressure (PEEP) with alveolar recruitment maneuvers reduced the risk...
Obese patients undergoing general anesthesia and mechanical ventilation during laparoscopic abdominal surgery commonly have a higher incidence of postoperative pulmonary complications (PPCs), due to factors such as decreasing oxygen reserve, declining functional residual capacity, and reducing lung compliance. ...
We conclude that PEEP greater than or equal to 15 cm H2O can be used in infants and children to decrease Qsp/Qt toward normal; CI and avDO2 can usually be maintained in an acceptable range. Patients should be frequently monitored for pulmonary barotrauma. 展开 ...
Duration of ventilation, ICU stay and hospital stay (median and interquartile range) and hospital survival were determined. Results: There were significant overall differences between groups when considering plasma IL-8 and TNF-a. For plasma IL-8, the control group was 41% higher than the ...
The blood volume was measured by iodinated I-125-serum albumin and brought into the normal range, before the study began, with appropriate volume therapy. Serial cardiorespiratory data were taken before and after PEEP was increased from zero to 20 cm H2O, in 5 cm increments. PtcO2 correlated ...
lower sample size of the ECMO subgroup, beneficial impact of fluid administration required to maintain ECMO flow on lung recruitability, or preventive effect of ECMO on fibrotic changes potentially involved in the progressive loss of recruitability observed under standard ventilation [30], although this...
