May warrant caution with oxygen in chronic HF; hypothesis-generating for LVEF-dependent effects.
Does pure oxygen administration alter hemodynamics in patients with chronic heart failure?
Oxygen administration in chronic heart failure reduces cardiac output primarily by decreasing heart rate, but in severe dysfunction, peripheral effects dominate due to impaired central chemoregulation.
Saadjian et al. (1999) studied this question.
