Oxygen is essential for sustaining life, and its levels in the body play a crucial role in our health. While the human body is remarkably adaptable, how low can your oxygen level go before you die? Understanding these thresholds is vital for recognizing and responding to potential medical emergencies.

Normal Oxygen Levels:

In healthy individuals, blood oxygen levels are typically within a range of 95% to 100%. This means that the blood is carrying a high concentration of oxygen to cells and tissues, ensuring their proper functioning.

Hypoxemia:

When blood oxygen levels drop below the normal range, a condition called hypoxemia occurs. Mild hypoxemia, where levels are around 91-94%, can cause shortness of breath and may be seen at high altitudes. However, severe hypoxemia, where levels drop below 90%, is a cause for immediate concern.

Hypoxia:

Hypoxia refers to a state where oxygen levels in tissues are inadequate. This can occur even if blood oxygen levels are normal, due to factors that prevent proper oxygen utilization at the cellular level.
