PADI Divemaster Certification Practice Exam

What occurs during dry suit squeeze?

1. Air is added to the dry suit during descent

2. The dry suit compresses due to external pressure

3. Water leaks into the dry suit

4. The diver overexerts themselves

The correct answer is: The dry suit compresses due to external pressure

During dry suit squeeze, the dry suit compresses due to external pressure. As a diver descends, the surrounding water pressure increases. If the dry suit is not properly adjusted or if there isn’t enough air inside the suit to counteract this increase in pressure, the suit can constrict around the diver's body. This results in discomfort and can restrict movement, which is why it’s crucial for divers to manage air in their dry suits correctly by adding air during ascent and descent. In contrast, the addition of air to the dry suit during descent is a preventive measure against squeeze, rather than a description of what occurs during the event itself. Water leaking into the dry suit is typically a result of damage or improper fitting, rather than pressure changes. Lastly, overexertion pertains more to the diver's physical condition and activity level than the effects of pressure on the dry suit. Understanding the mechanics of how external pressure impacts the suit is important for safe and effective diving practices.
