(a) respiratory depression.
Step-by-step explanation:
Respiratory depression means that a person’s rate and depth of breathing are lower than normal. This results in low oxygen levels and high carbon dioxide levels in the blood.
Substance-induced respiratory depression occurs when an individual experiences a significant decline in their inhalations and exhalations as a result of using some drug or medication.
It is the common side effect of drugs that suppress functions of the central nervous system. Substance-induced respiratory depression can occur in conjunction with the use of numerous drugs.
