What happens to body when spo2 is around 52 percent?

When blood oxygen saturation (SpO2) levels drop to around 52 percent, the body experiences severe hypoxemia, which can lead to significant organ dysfunction due to inadequate oxygen supply. Symptoms may include confusion, extreme fatigue, shortness of breath, and cyanosis (bluish discoloration of the skin). Prolonged exposure to such low oxygen levels can result in critical conditions such as respiratory failure, cardiac arrest, and potentially death if not treated promptly. Immediate medical intervention is necessary to restore adequate oxygen levels.
