Prediction of haemodynamic reactivity during total intravenous anaesthesia for suspension laryngoscopy using Analgesia/Nociception Index (ANI): a prospecti... BACKGROUND: The Analgesia/Nociception Index (ANI), a 0--100 non--invasive index calculated from heart rate variability, reflects the analgesia/no...
Twitter Google Share on Facebook collateral ventilation the process by which gas passes from one lung unit to a contiguous unit through alveolar pores or direct airway anastomoses; the mechanism that explains lack of atelectasis distal to an obstructed bronchus; sometimes also called collateral air ...
For this part of the study , full neuromuscular paralysis was initiated and maintained with i.v. pancuronium bromide (0.2 rug/kg/h). Tidal volume and venti- lator rate were adjusted to maintain normocapnia. A very slow inflation of the lung was then performed from zero Pao up to 0.7 ...
V + 2:b'jSj where Y is the dependent variable of interest (ascending aortic blood flow, heart rate, or mean systemic arterial pressure); bo (the intercept of the equation) is its mean value over all the observations (an observation is the measurement of that depend- ent variable for ...
High-frequencyjet ventilationinstills gas at a rate of 100 to 400 breaths per minute. Tidal volumes are significantly smaller than dead space volume, so convective or bulk flow is not responsible for gas exchange in this setting. Instead, laminar flow, mixing via Taylor dispersion, Pendelluft,...
Oxygenation index (Fio, X MA,P X lOO/Pao, [mm Hgl) and ventilation index (respiratory rate x PIP x Paco,/lOOO) were calculated. Statistical analysis was performed using the Wilcoxon signed-rank test for paired nonparametric data. All results are medians with ranges. The age of the ...
Measurements of arterial blood gases, peak and mean airway pressures (Paw), blood pressure (BP), and heart rate (HR) were recorded during baseline CMV, after every 30-min period during jet ventilation, and again 30 min after returning the patient to CMV. For analysis, patients were...
The rate of ROSC upon admission to the hospital in the ETI group (ES = 0.27, 95% CI: 0.13-0.42) was significantly higher than that in the SGA group (ES = 0.18, 95% CI: 0.13-0.23) and BMV group (ES = 0.16, 95% CI: 0.10-0.22). Compared with the BMV group (ES = 0.09, 95...
Fetuses were ventilated in utero (groups 1– 4) at 110 d gestation using room air, a peak inspiratory pressure of 40 cm H2O, a positive end-expiratory pressure of 4 cm H2O, an inspiratory flow of 15 L/min and a rate of 65 breaths/min. Our goal was to ventilate using a strategy ...
