assumed that baby Amira is in respiratory distress. Amira is currently receiving 30% flow-by oxygen at 10 minutes old to maintain oxygen saturation (Sa02) levels of 92%. Although the target Sa02 level at 10 minutes old is between 85-90% (Department of Health and Human Services‚ 2014) the fact that Amira is still displaying signs of nasal flaring and moderate work of breathing despite receiving flow-by oxygen is concerning. After conducting a brief initial top to toe assessment‚ weight and length‚ Amira

Jorge Nuñez Ms. Principe / Period 2 February 8th‚ 2011 Aim: How are we going to determine the empirical formula of a compound? Do Now: 1) What is the percent by mass of oxygen in H2C2O4? H2 = 2(1) = 2 ; C2 = 2(12) = 24 ; O4 = 4(16) = 96 Gram Formula Mass = 90 Percentage of Oxygen = 6490 x 100 = 71% 2) Calculate the percentage of water: -Mass of empty crucible and cover = 11.7g -Mass of crucible‚ cover‚ and hydrate before heating = 14.9g -Mass of crucible‚ cover‚ and

movements. The skeletal system and the muscle system maintain to posture and produce heat for the body. Increased blood supply: As people start to exercise the muscles will start wanting more oxygen to work faster so it can produce more energy at a faster rate‚ to keep up with the movement in the muscles. The oxygen in our red cells and the other nutrients are stored in the muscles to supply these muscles with energy which is called (glucose.) When people do short exercises such as running for a short

As the subject enters the exercise phase there is an increased metabolic demand due to the heightened workload of the skeletal muscles and organ systems. In order to accommodate this rise in oxygen demand there must be an increase in the subject’s minute ventilation. The rise in minute volume‚ with exercise‚ could be accomplished by increasing the volume of each breath‚ the tidal volume‚ increasing the respiratory rate or by some combination of the two. In the subject’s case it was a combination

occurs. The equation for photosynthesis is 6 CO2 + 6H2O + light energy=C6H12O6 + 6O2 meaning that when a plant cell absorbs carbon dioxide and water alongside sunlight then the plant will put off glucose and oxygen gas in result. This process is where humans and other heterotrophs get their oxygen to survive. Sunlight is captured through a pigment called chlorophyll‚ which absorbs every color light wave expect green‚

Body temperature When we exercise the body has to work harder‚ the body temperature would increase this is due to organs having to work harder to get oxygen to muscles. The metabolic rate that produces more energy has to increase in order for more energy to be released. The heart has to pump more blood around the body in order to deliver oxygen to the working muscles so they can carry on working at that capacity. What mechanisms are there to cool the body down?
