Cerebral blood flow during high frequency ventilation in cats

Cerebral blood flow during high frequency ventilation in cats

Cerebral blood flow (CBF) was compared during conventional low frequency ventilation (LFV) [tidal volume 15 ml/kg, respiratory rate 12] and high frequency ventilation (HFV) [tidal volume 3 ml/kg, respiratory rate 100] in normal cats. The intra-arterial 133Xenon technique was used to determine CBF. N...

Description
Summary:Cerebral blood flow (CBF) was compared during conventional low frequency ventilation (LFV) [tidal volume 15 ml/kg, respiratory rate 12] and high frequency ventilation (HFV) [tidal volume 3 ml/kg, respiratory rate 100] in normal cats. The intra-arterial 133Xenon technique was used to determine CBF. No significant difference in CBF was present between the 2 groups. The mean CBF was 46.6 +/- 14.2 ml/dl X min during LFV and 44.4 +/- 12.2 ml/dl X min during HFV. Additionally, mean arterial pressure, CVP, intracranial pressure (ICP), cerebral perfusion and airway pressures were not significantly different between the groups. HFV has little effect on cerebral hemodynamics.
