The first physiological sign of oxygen depletion is dizziness. When the oxygen levels in the body begin to drop, the brain is one of the first organs to be affected due to its high metabolic demand for oxygen. Dizziness can occur as a result of insufficient oxygen supply to the brain, which may cause lightheadedness or a feeling of unsteadiness. It is an early warning sign that the body is not receiving adequate oxygen, prompting individuals to take immediate action to restore oxygen levels.

Understanding the physiological effects of oxygen deprivation is crucial in the context of vapor recovery systems, where adequate ventilation and oxygen exchange are essential for safety and efficiency. Recognizing dizziness as a primary sign allows individuals to react swiftly to potential hazardous environments, ensuring their safety and the effectiveness of the recovery systems.
