While the term ‘normal blood pressure’ can vary slightly based on age and health, the guidelines provided by The American College of Cardiology and the American Heart Associationcategorize blood pressure readingsas on aBP chartbelow. The primary symptom of hypertension often takes the form of a ...
Picture of Hemoglobin A1c Chart Hemoglobin (sometimes abbreviated as Hb) is a complex protein found in red blood cells that contains an iron molecule. The main function of hemoglobin is to carry oxygen from the lungs to the body tissues, and to exchange the oxygen for carbon dioxide, and ...
* These levels gradually average higher as the altitude where people live increases. This is a result of the increased demand for the oxygen-carrying capacity of red blood cells at higher altitudes where there is decreased oxygen concentration in the atmosphere. These values may vary from authoriti...
High diastolic blood pressure may be rare, but it’s still an important thing to note because diastolic blood pressure is an important indication of cardiovascular health. Since this number measures the blood pressure between heartbeats, a high level may mean less effective delivery of oxygen to ...

Many aquatic insects emerge as adults from water bodies to complete parts of their life cycle in terrestrial ecosystems and are potential prey for riparian predators. The benefits of riparian predators from aquatic insects include higher contents of long
Green hydrogen produced by water splitting using renewable electricity is essential to achieve net-zero carbon emissions. Present water electrolysis technologies are uncompetitive with low-cost grey hydrogen produced from fossil fuels, limiting their sca
Enhancing tissue oxygen uptake and delivery is crucial to such adaptation to lifelong hypoxia. For example, Tibetans can maintain a normal hemoglobin concentration but have a higher level of blood flow than lowlanders, whereas Andean natives have high hemoglobin concentration1. Meanwhile, yaks in the...
