Which of the following complications is NOT associated with noninvasive ventilation?

Noninvasive ventilation, while effective in managing respiratory failure and related conditions, can lead to various complications due to its methods and equipment. Increased heart rate is not typically recognized as a direct complication associated with noninvasive ventilation. Instead, heart rate may be influenced by factors such as underlying respiratory distress or anxiety rather than the ventilation technique itself.

In contrast, skin problems can occur due to the pressure from masks or interfaces used in noninvasive ventilation, leading to discomfort or even pressure sores. Gastric distention can be a result of air swallowing, which can happen due to increased respiratory effort or improper mask fit. Eye irritation can arise from leaks in equipment, leading to air blowing towards the eyes, causing dryness or discomfort. Each of these complications highlights issues directly related to the use of noninvasive ventilation equipment and patient interaction with it. Thus, the absence of increased heart rate as a complication distinguishes it from the others listed.
