hypoxémiában

Hypoxemia is a medical condition characterized by abnormally low levels of oxygen in the blood. This occurs when the body's tissues and organs are not receiving enough oxygen to function properly. Hypoxemia can be caused by a variety of factors affecting the respiratory system, such as pneumonia, chronic obstructive pulmonary disease (COPD), asthma, or pulmonary embolism. It can also be related to heart conditions that impair blood circulation or altitude sickness.

Symptoms of hypoxemia can vary depending on the severity and underlying cause. Mild cases might manifest as shortness of breath, rapid breathing, and a bluish tint to the skin, lips, or nail beds (cyanosis). More severe hypoxemia can lead to confusion, dizziness, fatigue, and in critical situations, loss of consciousness and organ damage.

Diagnosis typically involves measuring the partial pressure of oxygen in the arterial blood (PaO2) through an arterial blood gas test. Pulse oximetry, a non-invasive method, can also provide an estimate of blood oxygen saturation. Treatment focuses on addressing the underlying cause and increasing oxygen levels, which may involve supplemental oxygen therapy, medication, or mechanical ventilation. Prompt medical attention is crucial for managing hypoxemia and preventing serious complications.
