What is hypoxia defined as?
Introduction. Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).
What factor causes hypoxia quizlet?
Hypoxia results when the body lacks oxygen. It generally is associated with flights at high altitude. Other factors such as alcohol abuse, heavy smoking, and various medications can interfere with blood’s ability to carry and absorb oxygen, reducing the body’s tolerance to hypoxia.
What is type of hypoxia?
Four types of hypoxia are distinguished in medicine: (1) the hypoxemic type, in which the oxygen pressure in the blood going to the tissues is too low to saturate the hemoglobin; (2) the anemic type, in which the amount of functional hemoglobin is too small, and hence the capacity of the blood to carry oxygen is too …
What is hypoxia classified?
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body.
What are the kinds of hypoxia?
Hypoxia is actually divided into four types: hypoxic hypoxia, hypemic hypoxia, stagnant hypoxia, and histotoxic hypoxia.
How do you measure hypoxia?
Pulse oximetry is a noninvasive test that measures blood oxygen saturation. It can directly detect hypoxemia. Blood oxygen levels can be a direct indicator of tissue oxygenation, so pulse oximetry can diagnose hypoxia as well.

What is normal SpO2 level?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
