Step by step
Solved in 3 steps
- Explain the physiological and pathophysiological changes that occur with ascent to altitude. Provide examples Provide Steps.Can a person have the same VO2Max in a completely different activity?Start by defining RER and explain how and why the resting value is established (think back to bioenergetics). Next, explain how and WHY (again, this requires an understanding of bioenergetics) RER changes as exercise intensity is increased (think VT and RCP). Hints: consider the points where the production of a gas increases drastically and why this occurs. Furthermore, consider that VT is often used to approximate AT. Also keep in mind the endogenous buffering systems.
- Which of the following combinations would all result in an increase in stimulation to breathe? Group of answer choices decrease in PCO2 : increase in H+ : decrease in PO2 increase in PCO2 : increase in H+ : decrease in PO2 decrease in PCO2 : decrease in H+ : decrease in PO2 increase in PCO2 : decrease in H+ : increase in PO2 decrease in PCO2 : decrease in H+ : increase in PO2Continuous positive-airway pressure (CPAP) and Bi-level positive-airway pressure (BPAP) can be used to support breathing. What makes BPAP different from CPAP? Which device do you think is better to support breathing? Why? the article “Obesity Hypoventilation Syndrome” https://www.thoracic.org/patients/patient-resources/resources/obesity-hypoventilation-syndrome.pdfScenario: A stat arterial blood gas (ABG) reveals that the client is experiencing partially compensated respiratory acidosis. Use an X to indicate which result is associated with each factor that contributes to an ABG that is representative of partially compensated respiratory acidosis. All assessment findings should be used and can be used only once. Results pH PaCO2 PaO2 SaO2 HCO3 59 mm Hg 7.31 91% 89 mm Hg 29 mEq/L
- In the journal article about pulmonary rehabilitation for idiopathic pulmonary fibrosis (IPF), researchers used patients with chronic obstructive pulmonary disease (COPD) as a comparison group. Which data show that the patients had an obstructive disease? Right ventricular systolic pressure (RVSP) was slightly higher than normal TLC was 109% of predicted (based on the subjects sex, age and size) FEV1 was 80% of predicted (based on the subjects sex, age and size) Poor performance on the 6MWDThe below graph shows both ventilation and blood lactate concentration as a function of total oxygen consumption during a bout of exercise. Explain the relationship between these two variables and why these two measures (ventilatory threshold and lactate threshold) tend to occur around the same level of exercise intensity.Which of the following tests would be best fit to determine HRmax using a HR monitor in hockey athletes? running a mile under a fixed time limit for all athletes 30 second maximal sprint 20 meter shuttle run test (beep test)
