- The Rockport walking test evaluates the capacity of your lungs in relation to the volume of exercise you can tolerate. It is designed for both women and men between the ages of 20 and 69. To perform the Rockport walking test: Warm up for 5 to 10 minutes with easy walking. Start your stopwatch and immediately start walking as fast as you can. Make every effort to push yourself but avoid jogging. At the end of the 1 mile, stop your stopwatch and record your time in decimals. For example, 11 minutes plus (30 seconds ÷ 60 seconds) = 11.5 minutes. Take your heart rate immediately. If taking your own pulse, count the heartbeats for 15 seconds and multiply by four. For example, if there are 40 heartbeats in 15 seconds, your heart rate would be 160 beats per minute (bpm). Calculating Your VO2 Max Upon completion of the test, you will need to do some math to determine your VO2max. In addition to your heart rate, you will also need to measure your weight in pounds. The formula is as…Cases of accidental carbon monoxide poisoning occur when someone builds a charcoal fire in an enclosed area. Assuming help arrives in time, what would be the most effective treatment: placing the victim outdoors in fresh air or administering pure oxygen? Explain your answer.What is the RER of an individual with an oxygen consumption of 220 ml/min and a carbon dioxide production of 182.6 ml/min? Report your answer to 2 decimal points. QUESTION 29 What percent of the individual's oxygen consumption in the previous question is being used to combust carbohydrate for energy? Round your answer to the nearest whole number and answer with a number only as units are given in the question.
- A socially conscious thief has just stepped out of the drug store with a few different pill bottles. As she is traveling away from the scene of the theft on a bus, someone has a severe asthma attack. Being, as we said, socially conscious, she quickly looks at the contents of her pocket to maybe find something that will help. Which of the following contents would most help the asthmatic person? O A few quarters and a couple dollar bills O Alupent (a B2 adrenergic receptor agonist) O Phenylephrine (an al adrenergic receptor agonist) O Muscarine (a muscarinic receptor agonist)Energy cost for breathing significantly decreases with respiratory conditions. True FalseTrue or False If a person cannot breathe for a few minutes it can cause brain damage. A person in shock breathes slowly. If you lose a lot of blood in a few minutes you can die. To stop bleeding put pressure on the artery that carries blood. Call 144 for an ambulance. When a victim is in shock too much blood circulates through the body. You should always give first aid to a person even if you don’t know what to do.
- A student undertakes a project to determine the effect of carbon dioxide on respiration rate using the following methodology. A volunteer inhaled air from a bag containing a predetermined amount of carbon dioxide (with partial pressure in torr) and the number of breaths per minute was recorded. Her data are given below: Partial pressure CO2 (torr) Respiration rate (breaths/minute) 30 8.1 32 8.0 34 9.9 36 11.2 38 11.0 40 13.2 42 14.6 44 16.6 46 16.7 48 18.3 50 18.2 Choose the best statistical test for this study. a. Correlation b. Simple Linear Regression c. Non-Linear Regression d. General Linear Model RegressionWith COPD, there is a decreased air flow from the lungs. This coyly be caused by which of the following reasons? Select all that apply.You need to administer 250 mg of erythromycin (Erythrocin) PO. You have on hand 0.5 g tablets. How many tablet(s) will you give? Fill in the blanks. Answer: tablet(s)
- Lung model with heart, larynx and diaphragm Identify the following structures with the help of your textbook and the keys Larynx, trachea Thyroid cartilage, cricoid cartilage, tracheal cartilage Cricothyroid ligament, thyrohyoid membrane Inside the model (not shown in the picture): Esophagus, Bronchi: Main/Primary bronchus, Lobar/Secondary bronchus, Segmental/Tertiary bronchus, Terminal bronchiole Lungs: Apex, base, diaphragm. In the right lung: Transverse fissure, oblique fissure, superior lobe, middle lobe, inferior lobe. In the left lung: oblique fissure, superior lobe, inferior lobe, cardiac notchSection B: (Minds-on) An experiment was carried out on a person in which the volume of the air taken in at each breath, and the number of breaths per minute were measured at rest and after running. The results are shown in the following table: Breaths per minute Volume of air per breath 450 cm3 At rest 20 After running 1 000 cm3 38 2.1 Explain why the amount of air taken up into the lungs increases after exercise (3) 2.2 Describe the changes that took place in the human body to bring about an increase in the breathing rate of the person. 2.3Twenty percent of the air breathed in consists of oxygen. Sixteen (3) percent of the air breathed out, consists of oxygen. Calculate the amount of oxygen entering the blood per breath after running. Show all calculations. (4)you can create a bar graph or a line graph to represent the respiratory volumes and capacities measured using a wet spirometer. The x-axis can represent the different volumes and capacities measured, and the y-axis can represent the values in liters. You can use different colors or patterns to represent the different measurements taken for each individual
