Well there are many factors that go into the categorization of different life singers in each aquatic system, from the ph levels in the water, the temperature, the depth, the presence of lights, as well as foreign factors s as well such as natural disasters, human/unnatural predatory fishing (invasive), and not to mention pollution, all of which can change the balance of an aquatic system to a minimal degree to turning it into an ecological “dead zone”
The most important approach for the nurse to use when applying a nasal cannula is TO MEASURE OXYGEN SATURATION.
Measuring oxygen saturation gives data about a person's overall oxygenation. Oxygen saturation is measured with the help of a Pulse Oximeter. It is a small device that is clipped to the finger to measure oxygenation.
Oxygen saturation refers to the fraction of oxygen-saturated hemoglobin as compared to the total hemoglobin in the body.
It should be C. direct contact.
Water at 4 degrees centigrade has the highest density of all other water temperatures. This is why ice (whose temperature is below 0 degrees) floats on very cold water. This phenomenon is significant in the Artic and Antarctic where ice shelves float on cold ocean waters in the poles. Animals that live in these regions (such as seals and polar bears) use these ice shelves as hunting platforms.
