Interpretation Provides information to assist in interpretation of the test results. Creatine kinase MB (CKMB) levels can be detected within 3 to 8 hours of the onset of chest pain, peak within 12 to 24 hours, and usually return to baseline levels within 24 to 48 hours.
Elusive Whales Set New Record for Depth and Length of Dives Among Mammals. A new study of elusive Cuvier's beaked whales shows they can dive to nearly 10,000 feet (3,000 meters). View Images. A Cuvier's beaked whale swims just under the surface of the ocean near the GalÃ¡pagos Islands.
a blue whale can reportedly hold it breath for up to 20 minutes. How long whales stay under water during normal feeding dives and how long they can stay under water if they have to is quite different. Blue whales can stay submerged for about 40 min but their dive lengths are more on the order of 10-15 min. Hope this helped!
