Lung Physiology Flashcards
What is starlings equilibrium
At capillaries, pressure forces blood out, oncotic pressure in
Excess taken away by lymph
What affects Starlings equilibrium
HF - Increased Venous pressure
KF - Protein lost so less oncotic pressure
LV - Less proteins made so less oncotic pressure
What is the oxygen dissociation curve?
What does haemoglobin look like?
Where in the lung is there more oxygen and why?
The top, due to higher ventilation and less perfusion
At the bottom both increase, but perfusion is now greater than ventilation
What can massively increase ventilation without perfusions
bleb
What can reduce ventilation compared to perfusion
COPD, Asthma
where does DPG force the oxygen dissociation curve?
Right
What is the bohr effect?
Oxygen association is inversely related to Co2 or H ions
