Hypoxia and Medicine

what is the differnce between hypoxemia and hypoxia?

Public Comments

1. Hypoxaemia (or hypoxemia) is a deficiency in the concentration of dissolved oxygen in arterial blood. A frequent error is made when the term is used to describe poor tissue diffusion as in hypoxia. It is possible to have a low oxygen content (e.g., due to anaemia) but a high PO2 in arterial blood so incorrect use can lead to confusion. Hypoxaemia is different from hypoxia, which is an abnormally low oxygen availability to the body or an individual tissue or organ. Hypoxia literally means "a deficiency in oxygen." It can refer to: Hypoxia (medical), a shortage of oxygen in the body. Hypoxaemia is the reduction of oxygen specifically in the blood; anoxia is when there is no oxygen available at all. Hypoxia (environmental) or oxygen depletion, a reduced concentration of dissolved oxygen in a water body leading to stress and death in aquatic organisms.
2. going with the exact meaning of the words: "hypoxia" is the lack of oxigen (in the body), "hypoxemia" is the lack of origin in the blood. so i guess, somebody, let's say with a chronic pulmonary disease could have oxygen levels lower than usual in the blood, but his body could be adapted to this and function quite normally.
