- How is the Peak Respiratory Flow for men for women different Provide evidance and sources.The physiological mechanisms which have caused respiratory rate to change during exercise. Before exercise Results are: RR 14 bpm, SpO2 98%, BP 130/70 mmHg (Mean arterial pressure 90 mmHg), HR 74 bpm. No cardiovascular or respiratory diseases. After exercise respiratory rate is now 20 bpm, her SpO2 is 100% on room air, BP is 140/80 mmHg (Mean arterial pressure 100 mmHg), and HR is 90 bpm. Breathing deeply and using accessory muscles.Discuss the Respiratory quotient
- What change (increase or decrease) in arterial Pco2 leads to an increase in minute ventilation? Increase During normal resting conditions, arterial Pco2 is 40 mm Hg and minute ventilation is approximately 6.5 L/min. If the arterial Pco2 increased by 4 mm Hg. to what approximate value would minute ventilation increase? [Select] During normal resting conditions, arterial Poz is 100 mm Hg and minute ventilation is approximately 6.5 L/min. If the arterial Po2 decreased by 4 mm Hg, to what approximate value would minute ventilation increase? [Select] [Select] 5 L/min 6.6 L/min 9 L/min 12 L/min 15 L/min NextVentilation disorders have a significant effect on the volume of air entering the lungs and its availability for gas exchange. Explain the association between decreased ventilation and pulmonary hypoxic vasoconstriction. Link your understanding of this physiological phenomenon to pulmonary hypertension and cor pulmonale in relation to chronic obstructive pulmonary disease (COPD).Which of the folloqing statements about BPG and its effect on oxygen transport is NOT true? BPG binds more tightly to adult Hb than fetal Hb, thus facilitating the O2 transfer to the fetus. An initial reponse in adapting to higher altitude is increased BPG synthesis in erythrocites. This increase in BPG concentraton will shift the Hb saturation curve to a higher affinity position relative to its sea-level position, facilitating better O2 aborption and transport at higher altitudes. The presence of BPG in mammalian erythrocytes decreases Hb affinity for O2 BPG binds Hb in its central cavity in the R-state but not in the T-state, and in this way decreasing Hb affinity for O2 BPG binds Hb in its central cavity in the T-state but not in the R-state, and in this way decreasing Hb affinity for O2
- Compare the Peak Respiratory Flow of men vs women provide exmaplesThe fine-tuning of ventilation during exercise is none of the answers are correct mediated solely by neural mechanisms determined by PO2 mediated by blood pH and PCO2During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs
- Explain how CO2 loading and O2 unloading are connected in systemic gas exchange. Make sure to discuss in terms of the Law of Mass Action. Also chloride shift. How does this allow the delivery of oxygen to match the metabolic rate of the tissues? Why would that be important?Describe the effects of increased DPG on the oxygen–hemoglobin dissociation curve. What is the adaptive importance of the effect of DPG on the curve?describe how the normal pleural pressure differences cause regional difference in normal lung ventilation
