Riesling grapes are naturally very high in acid, and the cool, northern climate of Germany means this ripping acid stays in the grapes even into the fall harvest season. So winemakers let the fermentations stop before the wine is completely dry, retaining a little sweetness in order to strike balance in the wine.
Oxygenation refers to the process of adding oxygen to the body system. There is no way to reliably measure arterial oxygenation via clinical signs alone. Cyanosis, pallor and other physical findings are not reliable.
Extravasation is the inadvertent leakage of a vesicant solution from its intended vascular pathway (vein) into the surrounding tissue ( INS 2006; EONS 2011; Dougherty and Lister 2008; Doellman et al 2009; RCN 2010).
