1
Q

What shifts curve to the right

A

Increase temp (feer or exeercise), increase DPG (chronic lung dz), increase PCO2, decreased pH

MEans that less oxygen bound at same oxygen pressure as before

2
Q

Bohr effect with normal physiology

A

The venous pCO2 is higher than the arterial CO2…this means that the curve is shifted to the right

This means there is an increase in O2 delivered to cells due to the Bohr effect

Can also use graph to see total amount of O2 delivered

3
Q

During exercise

A

The PCO2 is even higher AND the O2 concentration is lower (in venous) so the difference in the amount of oxygen delivered is even higher

4
Q

Summarize Bohr effect

A

Facilitates O2 uptake in the lavolar capillaries and the O2 delivery in the peripheral tissue capillaries

Effect is more pronounced during exercise and in patients with lung dzs
