Question

Which of the following is not true? When Clearing a mask, you should:

1: Pull out slightly at the base of the mask to create a space for water to exit.
2: Inhale through your mouth, but exhale through your nose.
3: Take as many breaths as needed to clear the mask completely.
4: Look up during the last exhalation to make the bottom of the mask skirt the lowest point.

Answer 1

Statement number 2, which suggests inhaling through the mouth but exhaling through the nose while clearing a mask, is not correct. The proper technique is to exhale through the nose to clear the mask.

Step-by-step explanation:

The statement that is not true when clearing a mask is number 2: Inhale through your mouth, but exhale through your nose. When you are clearing a mask in activities such as scuba diving or snorkeling, the correct method is to exhale through your nose while tilting your head back slightly. This breath control allows for the proper expulsion of water from your mask. Breathing is mostly an involuntary action, but it can be consciously controlled, especially during activities like scuba diving. The nasal passages are known for filtering and warming the air, as well as creating greater pressure in the lungs during exhalation, which is beneficial for efficient breathing.
