Chris believes that markets move based on crowd psychology as evidenced by Fibonacci fractals, wave patterns, gold wave patterns, and sentiment. Chris uncovers the clues and finds the probabilities to help with forecasting key pivotal moves at tops and bottoms of market trends.
The P 50 is a conventional measure of hemoglobin affinity for oxygen. In the presence of disease or other conditions that change the hemoglobin's oxygen affinity and, consequently, shift the curve to the right or left, the P 50 changes accordingly.
So, the curve has an s-shape because, at lower PO2s, oxygen binds to hemoglobin at a high rate, and this slows down as hemoglobin become more saturated. At PO2s above 60 the curve is relatively flat, meaning that the oxygen content of the blood will not change much with subsequent increases in PO2. Shift to the left: The curve shifts to the left when hemoglobin has an increased affinity for oxygen, and has an easier time making the bond with oxygen. 2  Higher SpO2 for a given PO2. 3  Hemoglobin is more likely to cling to O2 and not let go (activity is minimal). 4  Think Cold.
