What are the bubbles detected by Doppler ultrasound equipment that precede DCS called?

• A. Air bubbles
• B. Silent bubbles
• C. Noisy bubbles
• D. Visible bubbles

Answer: (B)

The bubbles detected by Doppler ultrasound equipment that precede decompression sickness (DCS) are referred to as silent bubbles. These are small nitrogen bubbles that can form in the bloodstream following a dive, especially if a diver ascends too quickly. Silent bubbles are typically undetectable to the diver and may not produce any immediate symptoms, which is why they are termed "silent." Doppler ultrasound equipment is utilized to identify these bubbles in order to assess the risk of DCS. The presence of silent bubbles can indicate a problem that may lead to decompression sickness if not properly managed. Understanding the nature of these bubbles is crucial for divers, as it emphasizes the importance of adhering to safe diving practices and ascent rates to minimize their formation.
