Right shifting of curve means dissociation of oxygen from Haemoglobin.

Right shifting occurs in tissues.

Factors responsible for this -
1. Low partial pressure of oxygen
2. High partial pressure of carbon dioxide
3. High hydrogen ion concentration (decrease in pH)
4. High temperature
5. DPGA (Disphosphoglyceric Acid)
6. Exercise

Hello,


The oxygen dissociation curve can be shifted right or left by a variety of factors. A right shift indicates decreased oxygen affinity of haemoglobin allowing more oxygen to be available to the tissues. A left shift indicates increased oxygen affinity of haemoglobin allowing less oxygen  to be available to the tissues.

I hope this helps.
