Shortness of Breath
Shortness of breath or difficulty breathing is another major sign of hypoxemia and hypoxia, particularly during physical activities. You can also experience this condition during a period of inactivity or resting. This is because both hypoxemia and hypoxia cause a lack of oxygen to your lungs and make it harder for this organ to function normally. In some severe cases, you might need supplemental oxygen or mechanical ventilation to prevent life-threatening conditions when the diseases progress. [2]
