Final answer:
Some causes of irregular respiratory pattern include head injury, stroke, metabolic derangement, and toxic inhalation.
Step-by-step explanation:
Some causes of irregular respiratory pattern include head injury, stroke, metabolic derangement, and toxic inhalation. For example, a head injury may disrupt the normal functioning of the respiratory centers in the brain, leading to irregular breathing. Similarly, a stroke can damage the areas of the brain responsible for controlling respiration, causing irregular patterns. Metabolic derangement, such as acidosis or alkalosis, can also affect respiratory function and lead to irregular breathing patterns. Finally, toxic inhalation can damage the respiratory system and disrupt normal breathing.
