Continuous positive airway pressure (CPAP) that are too high may cause:

• A. Arousals and unwanted changes in respiratory patterns
• B. Excessive sneezing
• C. Increase in oxygen saturation
• D. More obstructive apneas

Answer: (A)

Too-high CPAP pressure disrupts sleep by creating an uncomfortable, oppressive sensation as the airway is continually bombarded with pressure. That discomfort often leads to arousals or partial awakenings, which fragment sleep. When the sleeper briefly wakes or shifts due to the excessive pressure, the breathing pattern can become irregular or shallow as the body reacts to the abnormal stimulus. In this context, the most consistent adverse outcome is arousals accompanied by changes in respiratory pattern. Sneezing isn’t typically tied to excessive CPAP. While CPAP generally improves oxygenation, an overly large pressure isn’t described as causing a beneficial rise in oxygen saturation and isn’t the problem being highlighted. CPAP’s role is to reduce obstructive events; excessive pressure tends to cause sleep disruption rather than more obstruction.
