Hypoxemia is defined as a condition where arterial oxygen tension or partial pressure of oxygen (PaO2) is below the normal value, which is typically between 80 and 100 mmHg. Alveolar ventilation is ...

The physiology of chronic hypoxia encompasses an enormous field of knowledge. This review concentrates on two areas in which important advances have recently been made. The first is hypoxia-inducible ...

A baby girl presented with symptomatic sickle cell disease exacerbated by mild hypoxemia, despite a newborn-screening diagnosis of sickle cell trait. DNA sequencing of the β globin gene revealed that ...

OXYGEN deficiency is one of the most common of all categories of atmospheric hazards. It stands to reason that the sensors used to measure oxygen concentration are one of the most widely used types of ...

The earth's atmosphere contains 20.9% oxygen, but the critical factor is its partial pressure. At sea level (1 Bar) this equates to 150mm Hg, but at 4000m it's down to 70mm. Hg. At this altitude (as ...

Consistent practice of yoga postures and pranayama increases the lung's airflow, air capacity, stamina and efficiency. Back bending postures open the chest, improving both lung and heart functions.
