Concerns of one lung ventilationcausesventilation perfusion ( V / Q ) mismatch

by the combination of increased perfusion(passive) caused bya ventilation / perfusion ( V / Q ) mismatch

this positioncan causesevere ventilation / perfusion mismatch

Surfactant lossleadsto atelectasis , ventilation perfusion mismatch

by shunting of blood(passive) caused byventilation - perfusion ( v / q ) mismatch

disorders of renal disease(passive) caused byventilation perfusion mismatch shunt

the wallscausesventilation - perfusion abnormalities

by aspiration of water(passive) caused byventilation perfusion abnormalities

Occlusion of blood flow to lungscausesventilation - perfusion ration to mismatch

by increased lung(passive) caused byventilation perfusion mismatch

pulmonary diseases(passive) may be caused byThis ventilation / perfusion mismatch

Atelectasis Reduced ventilationleadsto ventilation - perfusion mismatch

The resulting dead space ventilation andcausesventilation / perfusion mismatch

the left pulmonary collapse(passive) caused byventilation - perfusion mismatch

The ventilation is therefore affectedleadingto a ventilation perfusion mismatch

Hypoxia is thoughtto result primarilyfrom ventilation / perfusion mismatch

by positive pressure ventilatory support(passive) caused byVentilation / perfusion mismatch

The collapsed lungleadsto a ventilation - perfusion mismatch

by perfusion of collapsed lung units(passive) caused byventilation to perfusion mismatch

by shunting of blood(passive) caused byVentilation - perfusion mismatch

by the decreased cardiac output(passive) caused bythe ventilation / perfusion mismatch

gas exchangeleadingto ventilation / perfusion mismatch

Insufficient inflation of the lungs , which can result from inadequate mechanical ventilation or an associated injury such as flail chestcan also contributeto the ventilation / perfusion mismatch

Primary pulmonary hypertensioncausesventilation - perfusion mismatch

by the general anesthesia(passive) caused bythe ventilation / perfusion mismatch

respiratory reservecausingventilation / perfusion mismatch

The dilation of these blood vessels causes overperfusion relative to ventilationleadingto [ [ ventilation - perfusion mismatch
