Which respiratory rate indicates effective treatment of magnesium toxicity with calcium gluconate?

A respiratory rate of 12-20 breaths per minute indicates effective treatment of magnesium toxicity with calcium gluconate because this range falls within the normal respiratory rate for adults, which is typically between 12 and 20 breaths per minute. A respiratory rate in this range suggests that the patient is adequately ventilating and exchanging gases effectively, which is crucial since magnesium toxicity can lead to respiratory depression due to its effects on neuromuscular transmission and respiratory muscle function.

In cases of magnesium toxicity, there may be significant respiratory changes, and a return to a normal respiratory rate after treatment with calcium gluconate indicates that the patient's respiratory function is stabilizing and that the effects of magnesium are being reversed. Maintaining a normal respiratory rate is essential for ensuring adequate oxygenation and carbon dioxide elimination, critical aspects of recovery during magnesium toxicity management.
