Hypoxemia is low levels of oxygen in your blood. It causes symptoms like headache, difficulty breathing, rapid heart rate and bluish skin. Many heart and lung conditions put you at risk for hypoxemia.
Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin. Many chronic heart and lung conditions can put you at risk for hypoxia.
Your body tightly regulates the amount of oxygen saturation in your blood, because low blood oxygen levels can lead to many serious conditions and damage to individual organ systems, especially your brain and heart.
Supplemental oxygen therapy helps people with COPD, COVID-19, emphysema, sleep apnea and other breathing problems get enough oxygen to function and stay well. Low blood oxygen levels (hypoxemia) can damage organs and be life-threatening. You may need oxygen therapy for life or temporarily. Healthy blood oxygen levels help you feel and sleep better.
In cerebral hypoxia, your brain doesn’t get enough oxygen. That can happen if you can’t breathe or if something prevents blood, which carries oxygen, from getting to your brain. Without oxygen, your nervous system can’t send nerve signals and messages throughout your body so you breathe, move, speak and see.
If you have blood test results that show your hemoglobin level is lower than normal, it means you have fewer red blood cells doing essential work — that is, carrying oxygen throughout your body. A low hemoglobin level may not be a cause for alarm. Many things affect hemoglobin levels.
Your body normally tightly regulates the amount of oxygen and carbon dioxide in your blood, because low blood oxygen levels can lead to many serious conditions and damage to individual organ systems, especially your brain and heart.
Long-term (chronic) exposure to low levels of oxygen can increase your EPO levels. This may be due to chronic smoking or living in a high-altitude environment where air oxygen levels are lower. Elevated EPO from a high-altitude environment is normal and appropriately high.
If you show signs of low oxygen levels, your healthcare team will suspect type A causes — such as cardiac or respiratory failure, sepsis or shock — and treat these emergency conditions first. In the absence of low oxygen findings, they’ll consider various type B causes and attend to those specifically.
An electrolyte imbalance occurs when certain mineral levels in your blood get too high or too low. Symptoms of an electrolyte imbalance vary depending on the severity and electrolyte type, including weakness and muscle spasms. A blood test called an electrolyte panel checks levels.
