Final answer:
The symptoms of inadequate oxygen supply include dyspnea, cyanosis, and reaction of intercostal spaces.
Step-by-step explanation:
The symptoms of inadequate oxygen supply include dyspnea, cyanosis, and reaction of intercostal spaces. Dyspnea refers to difficulty breathing or shortness of breath, which is a common symptom of inadequate oxygen supply. Cyanosis is the bluish coloration of the skin and mucous membranes due to poorly oxygenated blood. Lastly, the reaction of intercostal spaces refers to the visible widening of the spaces between the ribs, which can occur when the body is trying to compensate for inadequate oxygen supply.
