At a given steady O2 consumption ( $$ \dot V{\rm O}_{\rm 2} $$ ) in normoxia, cardiac output ( $$ \dot Q $$ ) is inversely proportional to arterial O2 concentration (CaO2), so that O2 delivery ( $$ \dot Q{\rm aO}_{\rm 2} {\rm = }\dot Q\,C{\rm aO}_{\rm 2} $$ ) is kept constant and adapted to $$ \dot V{\rm O}_{\rm 2} $$ . The matching between $$ \dot Q{\rm aO}_{\rm 2} $$ and $$ \dot V{\rm O}_{\rm 2} $$ keeps O2 return ( $$ \dot Q\overline {\rm v} {\rm O}_{\rm 2} = \dot Q{\rm aO}_{\rm 2} - \dot V… CONTINUE READING
