True or False: Nitrous oxide has no negative effects on the cardiovascular system.

The statement that nitrous oxide has no negative effects on the cardiovascular system is not accurate. Nitrous oxide can affect the cardiovascular system, particularly at higher concentrations or in sensitive individuals. While it is often considered safe for use in dental and medical procedures, it can cause cardiovascular side effects such as hypotension, increased heart rate, and the potential to trigger arrhythmias in susceptible populations.

Understanding the pharmacological effects of nitrous oxide is essential, as it acts as a sedative and analgesic, but its effects on cardiovascular function should not be overlooked. Thus, the correct approach is to recognize that nitrous oxide does indeed have implications for cardiovascular health, making the statement false. This knowledge is crucial for ensuring patient safety during procedures involving nitrous oxide sedation.
