Patients fail to ventilate due to loss of sensitivity of the brain to the main stimulus to ventilation, CO2. It may also occur due to neurological, neuromuscular junction or ... If the patient is requiring more than 60% oxygen, they usually have a significant diffusion defect or ventilation perfusion mismatch.

This is a discussion on MedHelp about ventilation-perfusion mismatch. Community members of MedHelp provide help, support, guidance and discussion around the topic of ventilation-perfusion mismatch ... This is considered a ventilation-perfusion mismatch. When airsacs of the lung are destroyed, there is less surface area...

After 120 min of ischemia, severe ventilation-perfusion ( A/ ) mismatch developed within 15 min of reperfusion, with the appearance of low A/ areas and marked broadening of both perfusion and ventilation distribution in the midrange A/ regions.

(3). The exact mechanism of the reversed ventilation-perfusion; mismatch in this case could not be confidently determined. Using an animal model, Enjeti et al. (10) explained reversed ventilation-perfusion mismatch in regions of lobar collapse during concomitant positive end expiratory pressure.

We studied the spatial distribution of the abnormal ventilation-perfusion ( A/ ) units in a porcine model of acute pulmonary thromboembolism (APTE), ... An earlier report by Altemeier et al. (3) pioneered the study of A/ mismatch at 30 min after acute pulmonary bead embolization but did not report its spatial distributions.

When the V/Q is higher than 0.8, it means ventilation exceeds perfusion. ... When the V/Q is < 0.8, there is a VQ mismatch caused by poor ventilation.

Test Results Explained ... The aim is to identify a ventilation-perfusion mismatch, where there is gas uptake but reduced blood flow, suggesting a clot in a blood vessel. The interpreting specialist applies standard criteria and provides one of four possible results:
