This mismatch can occur due to a variety of reasons, such as lung diseases, blood clotting, or impaired gas exchange. In a healthy lung, the V/Q ratio is approximately 1:1, meaning that there is a balance between the amount of air and blood in the lungs. However, in cases of V/Q mismatch, the ratio becomes imbalanced, resulting in decreased oxygen levels in the blood and increased carbon dioxide levels. There are two types of V/Q mismatch: dead space and shunt. Dead space occurs when there is adequate ventilation but no blood flow, which means that the alveoli are not perfused. Shunt occurs when there is adequate blood flow but no ventilation, which means that the alveoli are not receiving enough air. V/Q mismatch can result in hypoxemia, which is a condition where there is a low level of oxygen in the blood. Hypoxemia can lead to symptoms such as shortness of breath, chest pain, and confusion. Treatment of V/Q mismatch depends on the underlying cause and may involve supplemental oxygen, bronchodilators, anticoagulants, or other therapies. #physiologylectures #physiologyvideos #physiology #fmge #fmgevideos #rapidrevisionfmge #fmgejan2023 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2023 #usmleprep #usmlephysiology
