Briefly explain how the respiratory exchange ratio is used to estimate which substrate is being utilized during exercise. What is meant by the term nonprotein R?

Which option best describes the following figure? Y (fraction saturation) 1.0 0.8 0.6 0.4 0.2 0.0 0 20 Oxygen Binding plot 40 60 p02 (torr) 80 100 A) Curve x = adult haemoglobin, curve y = fetal haemoglobin B) Curve x = myoglobin, curve y = haemoglobin C) Curve x = fetal haemoglobin, curve y = adult haemoglobin D) Curve x = fetal haemoglobin, curve y = myoglobin E) Curve x = adult haemoglobin, curve y - myoglobin

Explain the physiological mechanisms which cause Bertha respiratory rate to change during exercise Cues vital signs before exercise: Rr 14bpm  Sp02 98%, BP 130/70,Hr 74 After exercise Rr 20bpm, HR 90,BP 140bpm

A patient’s oxygen saturation is tabulated below. You plan to use these data to plot a graph. Time (sec) 0 30 60 90 120 150 180 210 O2 Saturation (%) 93 93 91 90 95 97 98 95   What is the range of values you will use on the y-axis? Minimum: Maximum
