Owner's Manual blood pressure monitor

Section 2: Diving with the Monitor 3 Air

Microbubble Warning

Repetitive diving may cause microbubbles to accumulate

in the lungs if the surface interval between dives is not

long enough. Ignoring decompression stops or an

excessive ascent rate can also lead to bubble formation.

In order to reduce the risk of decompression sickness for

future repetitive dives, the surface interval should be

planned long enough to reduce the risk of decompression

sickness. If the Monitor 3 Air calculates that the forma-

tion of microbubbles may occur during the surface

interval, it will advise the diver to extend the surface

interval. The display “Atn” (= attention) is visible in the

depth display area during the surface mode. While “Atn”

is displayed, the diver should not undertake another dive.

Note: If a dive has to be made while Atn is displayed,

the amount of Atn-time for the following dive can

increase considerably. During the dive, no-stop times will

be much shorter and decompression times will increase.
