Common manifestations of hypoxia often include confusion and irritability due to the brain being sensitive to low levels of oxygen. When the body experiences inadequate oxygenation, the central nervous system can become impaired, leading to changes in mental status such as confusion, disorientation, and behavioral changes like irritability. This occurs because the brain relies heavily on a continuous supply of oxygen to function properly, and any deficiency can cause significant disturbances in cognition and mood.

While increased heart rate can be a physiological response to lower oxygen levels as the body attempts to enhance oxygen delivery to tissues, it is not as directly indicative of cognitive impairment as confusion and irritability. Similarly, other symptoms like excessive sweating, paleness, nausea, or fatigue may occur under different circumstances or conditions but are not as specific to the cognitive effects of hypoxia. Therefore, the choice highlighting confusion and irritability aligns closely with the neurological consequences of hypoxia.
