Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery (arterial blood gas). It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter — a small device that clips to your finger.
Although they can vary from person to person, the most common hypoxia symptoms are:Changes in the color of your skin, ranging from blue to cherry red.Confusion.Cough.Fast heart rate.Rapid breathing.Shortness of breath.Slow heart rate.Sweating.More items...•
The earliest signs of hypoxia are: Confusion. Restlessness. Shortness of breath....The other signs and symptoms of hypoxia include:Bluish discoloration of skin, lips, and oral cavity.Decreased level of consciousness.Cough.Fast heart rate.Difficulty breathing.Slow heart rate.Palpitations.Sweating.
Pulse oximetry and ABGs are the two most important tests used to identify hypoxemia and hypercapnea. Pulse oximetry should be performed on all patients at risk for hypoxemia, assuming equipment is available.
Early signs of hypoxia are anxiety, confusion, and restlessness; if hypoxia is not corrected, hypotension will develop.

There are various mechanisms of hypoxemia. These are V/Q mismatch, right-to-left shunt, diffusion impairment, hypoventilation, and low inspired PO2.
Hypoxemia is often the result of a problem with gas exchange in your lungs, although it can have some other causes. Gas exchange happens in the alveoli, the tiny air sacs in your lungs that are surrounded by blood vessels called capillaries.
