What is the purpose of ball and socket clips on a full face mask?

The purpose of ball and socket clips on a full face mask is to maintain a secure fit. These clips are designed to provide a reliable locking mechanism that helps ensure the mask remains properly positioned on the patient's face throughout the duration of use. This secure fit is essential for effective ventilation, as it minimizes the risk of air leaks that can compromise the delivery of therapeutic gases. A well-fitted mask allows for optimal patient comfort while ensuring that the necessary pressure and volume of air can be effectively delivered for respiratory support.

The other options do not accurately describe the primary function of these clips. For instance, while they may help facilitate some aspects of mask handling, the clips are not primarily intended for easy removal or adjustment of the mask size; instead, their main role revolves around ensuring a snug, airtight seal against the patient's face.
