The question of how low can your oxygen level go before you die. Typically, a normal blood oxygen level (SpO2) is around 95-100%. When it drops below 90%, it's a cause for concern. If your oxygen levels consistently fall below 90%, it can lead to hypoxemia, which may result in organ damage or even be life-threatening. However, the exact threshold varies among individuals and depends on various factors, including age and overall health. If you or someone you know experiences persistently low oxygen levels, it's essential to seek immediate medical attention. Discussing your concerns in this forum can provide valuable insights and support during such critical times.
