Ventilation perfusion ratio is an indicator of how well the oxygen we breathe in is being transported through the lungs and into the blood system. A change from the normal value can indicate a disease/illness process that is causing less oxygen to get into the blood stream. Since our cells need oxygen in order to survive, this would obviously be a problem

What is ventilation perfusion coupling?
Ventilation perfusion coupling is the amount of gas reaching alveoli & blood flow in pulmonary capillaries; local autoregulation.
By what other names are lung perfusion scans and lung ventilation scans referred?
perfusion lung scan, aerosol lung scan, radionucleotide ventilation lung scan, ventilation lung scan, xenon lung scan, ventilation/perfusion scanning (VPS), pulmonary scintiphotography, or, most commonly, V/Q scan
Radioactive material is injected or inhaled and images are recorded?
"Lung Scan V/Q"ventilation perfusion scan radioactive test of lung ventilation and blood perfusion throughout the lung capillaries (Lung Scan)
What is V-P scan?
ventilation-perfusion lung scan (for detecting pulmonary embolism ed)
What is dead space in the lungs?
when its dead air and you cant use it to breath
What is V P scan?
ventilation-perfusion lung scan (for detecting pulmonary embolism ed)
What is ventilation-perfusion coupling?
Matching the amount of gas reaching the alveoli to the blood flow in pulmonary capillaries
What does the medical abbreviation V-P scan mean?
A V-P scan is a ventilation/perfusion scan. Sometimes it's called a V/Q scan as well. It is a radiology study to check how well air is getting into the lungs (ventilation) and how well blood is getting to the lungs (perfusion).
What is the compression-ventilation ratio for a lone rescuer?
30 compression and 2 ventilation
Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli?
True.
Compression-ventilation ratio for children?
For 1-person CPR the compression-ventilation ratio for children (and adults and infants) are 30 compressions to 2 breaths.
What is the purpose of lung perfusion scans and lung ventilation scans?
to detect pulmonary embolisms, determine how much blood is flowing to lungs, determine which areas of the lungs are capable of ventilation, and assess how well the lungs are functioning
