Morgan Billick September 4th‚ 2010 Ventilation and Oxygen Consumption Results Oxygen Concentration Oxygen concentration in water can be altered by the conditions it is exposed to. For instance cold water has a higher oxygen concentration than warm water. In our experiment we were able to observe the change in oxygen concentration of water at two different temperatures (15C and 25C) with a fish in each environment. Our results proved that the starting oxygen concentration of the cold water was

a low water temperature a fish slows down and so do its metabolic activities and when water temperatures are high‚ fish speed up and their metabolic processes increase as well. Proteins and enzymes are also affected by temperature changes. Oxygen is essential for the production of ATP from nutrients in cells; consequently oxygen must be delivered to a cell in sufficient amounts. Within fish‚ the counter-current exchange system allows for the efficient extraction of oxygen from the water by the gills

Ventilation and Oxygen Consumption in Fish Sally Ming Bio 102- PR# 2 12/12/12 Abstract Goldfish (Carassius Autarus)‚ when subjected to warm temperatures will have a high rate of ventilation compared to those exposed in colder environment. In a class experiment‚ we observed and recorded the effects of water temperature at [25 C] warm and [15 C] cold on ventilation and consumption rates in goldfish. For one hour at 15min intervals we observed differences in both ventilation and consumption

goal of this study was to measure the oxygen consumption of goldfish in an ambient environment and dark environment and calculate if there was any difference in metabolism based on oxygen consumption. The experimental hypothesis was that the metabolic rate of the goldfish as measured by oxygen consumption differs in a dark environment than in an ambient environment. The null hypothesis was that the metabolic rate of the gold fish as measured by oxygen consumption does not differ in darkness versus ambient

Abstract: Maximal oxygen consumption (VO₂max) is an excellent indicator of a person’s physical fitness level. It can also be used for many other things including diagnostic tools for physicians. In this study‚ two different methods of collecting maximal oxygen uptake scores were compared. The first being the predicted VO₂max score attained via the Rockport test and the second being indirect calorimetry VO₂max score attained through cycle ergometer and an attached metabolic cart.

VENTILATION QSB 1714 Prepared by: Mariatul Liza bt Meor Gheda Introduction Definition: The process of changing air in an enclosed space. A proportion of air within the enclosed space should be continuously withdrawn and replaced by fresh air. Drawn in from a clean external source: • At as high an elevation as practical…where more polluted air occurs at the relatively low levels found in congested towns and cities. Why do we need ventilation? Ventilation is needed

with A/C play a major part. This paper designs an embedded system for a vehicle cabin‚ which senses the gases like carbon-monoxide and oxygen and displayed at each and every second. If the level of the CO increases than the normal level (30ppm) or the level of the oxygen decreases than the normal level (19%) then an alarm is generated automatically and also ventilation is provided immediately. A warning message is sent to the authorized user via GSM. The advantage of this system is proper detection

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured and

| Mechanical Ventilation Weaning Protocol | A Gold Standard Nurse-Led Approach in the ICU | | Walden University | | Abstract This paper explores fifteen different medical and academic journals to show the importance of nurse-led Mechanical Weaning (MV) protocol. Based on studies conducted in the United States‚ Taiwan‚ Australia and New Zealand‚ the paper will show that without an effective weaning plan‚ the job of an intensive care unit (ICU) nurse becomes difficult and ineffective
