15 lut 2019 · Introduction. The human body is a highly aerobic organism that consumes oxygen according to its metabolic demand [ 1 ]. During aerobic respiration the presence of oxygen in addition to pyruvate, produces adenosine triphosphate (ATP), thus yielding energy to the entire organism [ 2 ].

22 gru 2022 · This diffusion gradient is known as the tissue partial pressure of oxygen (PtO) and varies with capillary density, oxygen consumption, metabolic rate, and blood flow. The brain has been found to require a partial pressure of oxygen between 30 and 48 mmHg.
29 lip 2023 · The partial pressure of oxygen (PO2) is a critical parameter that reflects the concentration of oxygen gas in a specific environment, such as the bloodstream or a gas mixture.
20 sty 2011 · The oxygen partial pressure (pO 2), which is a key component of the physiological state of an organ, results from the balance between oxygen delivery and its consumption. In mammals, oxygen is transported by red blood cells circulating in a well-organized vasculature.
22 wrz 2019 · Oxygen saturation is the percent of Hemoglobin (Hgb) binding sites in the blood that are carrying oxygen. Hemoglobin is a chemical molecule in the red blood cell (RBC) that carries oxygen on specific binding sites. Each Hgb molecule, if fully saturated, can bind four oxygen molecules.
24 maj 2024 · INTRODUCTION. Pulse oximetry measures peripheral arterial oxygen saturation as a surrogate marker for tissue oxygenation. It has become the standard for continuous, noninvasive assessment of oxygenation and is often considered the "fifth vital sign" [ 1-3 ]. Theoretical and clinical aspects of pulse oximetry will be reviewed here.
14 paź 2019 · The oxygen deficit, calculated from expired gas measurements made during quiet breathing coupled with pulse oximetry, is a good surrogate measurement of the ideal alveolar-arterial P o 2 difference and does not require arterial blood gas sampling.
