Optical Heart Rate and Blood Oxygen Level PC Based Monitoring System Optical techniques have been used for a long time to perform measurement in many areas. In many cases they relied on bulky equipment that were only used in the labs. Since the advent of the lasers and the advancement in light detectors and light emitting diodes, it has been possible to build portable equipment. Pulse oximetry is a non-invasive optical technique for monitoring the heart rate and the blood oxygen level. You are required to report on the theory of operation of such devices. You are then required to design, build and test a complete pc-based heart rate monitor system. Tasks I.    Survey the current methods used to monitor heart rate and blood oxygen level. Compare those with optical techniques. II.    Detail the principle operation of the optical pulse oximetry. III.    Design and build a practical optical probe that can be easily connected to the subject. IV.    Design and build the appr

points to be covered: Describe the methods used by the investigators. Describe the results of the study. Critically analyse the study (Were the methods appropriate? What do the results mean? Is the authors interpretation of the results supported by the data?) Write in an engaging style, appropriate to the intended audience, using good English.

Lesson 3.3 Case study CONCEPT MAP CASE STUDY ASSIGNMENT Case: H.N., a 3-year-old normally healthy, immunized girl with a runny nose and mild cough for the last 3-4 days woke up in the middle of the night with severe shortness of breath. She had expiratory wheezing. She was taken to the emergency department with HR 130, RR 44, Sat 93% and temp 37C. On physical exam, she had tight end-expiratory wheezing, intercostal and supraclavicular accessory muscles of respiration to help her breathe. A chest X-ray revealed hyperluscent and over-inflated lungs. Blood testing revealed an arterial blood pH of 7.25. Critical Thinking Questions: 1. What other questions in the history would have been helpful in this diagnosis, and why? 2. What medications would be helpful in treating this patient? What do you think the plan of care will be for this patient, and why? I expect a one page concept map of pathophysiology and one page to answer questions.

Readings Polit, D. F., & Beck, C. T. (2012). Nursing research: Generating and assessing evidence for nursing practice (9th ed.). Philadelphia, PA: Lippincott Williams & Wilkins. For this week’s Discussion, you are assigned to a group. Each group is assigned one of the following chapters. You are only be responsible for reading your assigned chapter. The Instructor will notify you of your group and assigned chapter by Day 1 of this week. Chapter 16, “Descriptive Statistics” This chapter introduces descriptive statistics, which, as the name implies, describe characteristics of the data. There is an overview of the different levels of measurement—nominal, ordinal, interval, and ratio—and how they are used. The chapter also defines frequency distributions and distinguishes between univariate and bivariate descriptive statistics. Chapter 17, “Inferential Statistics” This chapter focuses on inferential statistics, which are based on the laws of probability. I

1. Read the ICH E10 (have been uploaded) guideline on choice o control group in clinical trials. (a) Describe the ethical issues in placebo control control trails and explain how they might be overcome by design modifications. (b)Describe methodological issues in active-control trials and outline how they might be overcome. Use an absolute maximum of 600 words for each of parts 1(a) and 1(b). 2. Previous studies of Vinpocetine (an extract from the periwinkle plant) suggest that it improves the memory by increasing the blood flow in the brain. A neurologist suspects that the increased blood flow might also affect the IQ (as measured by the Wechsler Adult Intelligence Scale) by fostering cortical re-mapping. You have been approached to help design a Phase III clinical study to evaluate the hypothesis that 10mg of Vinpocetine daily increases the IQ by at least 10 points. (a) Describe in detail how the study should be undertaken. (b) Derive the necessary sample size for your study. You
