Severe Acute Respiratory Syndrome is caused by a virus‚ not a certain type of bacteria. This virus belongs to a class of viruses called coronavirus. Since SARS was an outbreak caused by a virus that was previously unknown‚ scientist named the virus that causes SARS‚ SARS-associated coronavirus (SARS-CoV). World Health Organization (WHO) physician Dr. Carlo Urbani identified SARS as a new disease in 2003 when he diagnosed a severely ill 48-year old businessman who was traveling from the Guangdong

Curiosity: What is the effect of temperature of saline on cardiac output? HYPOTHESIS: Cardiac output is higher in a hot saline and low in cold saline temperature parameters. Educated Guess Answer: Phenomenally cardiac output is supposed to rise in hot saline conditions and drastically go down in cold saline conditions. Normalising Data Table 2.1: Cardiac output normalised data of frogs in normal‚ hot and cold saline conditions Normal Hot Cold FROG SV(mV/beat) HR(beat/min) Cardiac output(L/min)

At the bottom of the bucket‚ there were 3 “dents” which were aligned with the dents at the bottom of the calorimeter jacket (#14). The oxygen combustion bomb (#15) was then opened and roughly 10 cm of the wire (metal wire provided by the instructor) was cut and attached to the arms of the cup so the pellet of choosing (which was either the Naphthalene or the Benzoic Acid) would ignite with

different medical careers and came upon respiratory therapy. I have a family friend that works as a respiratory therapist and when I started asking questions I became very intrigued. I signed up to job shadow for a day and instantly fell in love with the work! Being a respiratory therapist ties in my passion of wanting to help people and the challenge‚ I enjoy of constantly learning new things.

Lab Report 6: Respiratory Physiology Purpose: To describe the effects of carbon dioxide concentration on blood pH. Hypothesis: If the blood CO2 levels increase‚ the pH will decrease. Materials and Procedures: Materials: Willing subject (someone complete the activities of the experiment) Timer (with a second hand) Glass Urinary and Salivary pH (litmus) paper Drinking straw Procedures: 1. Measure 2 ounces of water in a glass. Obtain the pH of the

From a chemical perspective‚ what is oxygen? Identify its atomic number‚ the group it fits into OXYGEN in the periodic table‚ its chemical formula‚ its melting point‚ boiling point and state at room temperature. Oxygen is highly reactive‚ nonmetal‚ oxidising agent that readily forms oxides‚ it is an element. By mass‚ oxygen is the third-most abundant element after hydrogen and helium. The Atomic Number: 8 Group: The chalcogen group Chemical formula: 02 Melting

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater is

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.

Teaching Plan The learning objectives for this teaching plan are health promotion and prevention. As nurses it is important to promote good health and prevent disease. One goal for this teaching plan is that students will be able to promote respiratory heath in their patients. Another goal is that students will be able to learn how to prevent pneumonia in their patients. One intervention to promote health is to know who is at risk. Nurses need to know how to recognize who is at risk for pneumonia
