[Photo: Maggie Hoffman] A fifth of all of the wine grapes planted in Germany are riesling, so to talk about German wine, you have to start with this iconic grape. There's a lot to love: Riesling can taste like peach or apricot, with a bolt of lime-like tartness. It's also incredibly aromatic, all jasmine and honeysuckle.
Hemoglobin is responsible for transporting oxygen from lungs to other parts of the body, where the oxygen can be used by other cells. Oxy-hemoglobin (HbO2) is the bright red hemoglobin that is a combination of hemoglobin and oxygen from the lungs.A hemoglobin molecule can carry a maximum of four oxygen molecules.emoglobin is responsible for transporting oxygen from lungs to other parts of the body, where the oxygen can be used by other cells.

The PaO2, like I said, is the partial pressure of O2 in arterial blood-- typically measured via ABG. SaO2 doesn't measure tissue perfusion. It measures as a percentage the amount of hemoglobin molecules which are oxygenated (oxyhemoglobin) in arterial blood.PaO2 = measures oxygen in the blood (80-100).aO2 (and its indirect measurement SpO2) describe the amount of oxygen bound to hemoglobin in arterial blood. The term saturation likens hemoglobin to a sponge that becomes saturated with oxygen. The measurement is given as a percentage. PaO2 describes the amount of oxygen dissolved in arterial blood plasma.
