Oxygen saturation is a term referring to the concentration of oxygen in the blood. Hypoxemia describes a lower than normal level of oxygen in the blood. In order to function properly, the body needs to be above a certain level of oxygen circulating in the blood to perfuse the cells and tissues. When the oxygen level falls below this threshold, hypoxemia occurs. This may cause certain signs and symptoms to occur. Having short term low oxygen saturation can cause shortness of breath, which is generally one of the first symptoms. Anxiety, restlessness, fatigue and headaches are also common symptoms of short term hypoxemia. In an effort to increase the amount of oxygen in the blood, the respiration rate may increase to more than 24 breaths per minute. Heart rate is also frequently elevated to above 100 beats per minute to help circulate oxygen to meet tissue demands. Low oxygen saturation can also cause level of orientation problems such as confusion and short term memory loss. If hypoxemia becomes severe, brain function may become impaired, creating symptoms such as decreased attention span. Breathing may become irregular, with cycles of deep and shallow breathing. Endurance for physical activity decreases, and motor function, particularly for fine movements, can also become impaired. Cyanosis, a bluish discoloration of the skin and mucous membranes, becomes visible. As hypoxemia worsens, bradycardia and hypotension may occur. Ultimately, coma and death can result from severe, untreated hypoxemia. For long term low oxygen saturation conditions, which can last for several days or even longer, signs and symptoms will vary depending on the severity and duration.
