Quiz - 23 - Diving Knowledge Workbook - Diving Physiology

[Pedro Burrito]

From the Diving Physiology Section of the PADI Diving Knowledge Workbook Version 2.02 © PADI 2009:

Objective 2.8 - Define the term "silent bubbles" as it relates to decompression sickness.

Question 1

The term "silent bubbles" refers to bubbles that:

a. do not move, such as those that cause decompression sickness in joints.

b. cannot be heard with any form of electronic sensors.

c. are so small that they do not cause signs and symptoms of decompression sickness.

d. appear and disappear very quickly.​

I will post a daily question from my exams to help newer divers and to encourage more experienced divers to interact gracefully and helpfully with the newer divers.

Reminder - this is a post in the Basic Forum and it is a green zone. Please be nice and on topic.

Thank you for your patience while we try to give people something to discuss other than Covid-19 and/or Politics. I will post the answer covered by the spoiler tag later today.

Spoiler: Answer

c. are so small that they do not cause signs and symptoms of decompression sickness.

The term "silent" simply refers to the fact that the bubbles are so small that they apparently cause no symptoms of DCS. It has nothing to do with the ability to detect them.
