What are signs of a diver in distress?

The indication of a diver in distress primarily involves observing changes in their swimming patterns and breathing rhythm. Rapid breathing, also known as tachypnea, can signal that the diver is experiencing stress, panic, or insufficient oxygen supply. Erratic swimming is another key sign that the diver may not be able to maintain control or stability in the water, suggesting that they are struggling to manage their situation effectively. These two signs together are critical in identifying a potentially dangerous condition requiring immediate attention or intervention.

In contrast, calm movements and deep breaths would suggest that the diver is in control and not in distress, making those indicators less relevant for identifying a problem. Similarly, active communication and normal movements signify that the diver is functioning effectively and is likely not in distress. Therefore, recognizing the combination of rapid breathing and erratic swimming is essential for accurately assessing the safety of a diver in the water.
