What can cause respiration rates to drop?

Respiration rates can drop due to several factors, including respiratory illnesses like chronic obstructive pulmonary disease (COPD) or pneumonia, which impair lung function. Sedative medications and opioids can depress the central nervous system, leading to slower breathing. Additionally, conditions such as sleep apnea can interrupt normal breathing patterns during sleep. Lastly, severe metabolic issues, like acidosis, can also affect respiratory drive.
