Which statement is true regarding the respiratory effects of low doses of ketamine?

• A. Causes respiratory depression
• B. Reduces protective airway reflexes
• C. Maintains spontaneous respirations
• D. Increases respiratory rate significantly

Answer: (C)

Low doses of ketamine are known for their unique properties in the context of respiratory effects, making the statement about maintaining spontaneous respirations true. Ketamine is considered to be a dissociative anesthetic, and at low doses, it tends to preserve airway reflexes and respiratory drive, which is advantageous in various clinical scenarios. This characteristic allows patients to maintain spontaneous respiration, meaning that they can breathe on their own without significant compromise during sedation. This is particularly important in emergency and prehospital settings where airway management is critical. In contrast, higher doses of ketamine or the use of other anesthetics can lead to respiratory depression or reduction in airway reflexes, which increases the risk of airway obstruction or inadequate ventilation. Therefore, recognizing the respiratory effects at low doses is essential for safe administration and patient management in emergency settings.
