Physiologic Dead Space
{"Image DocumentName": "Physiologic Dead Space", "Image ImageDescription": "Optimal diffusion requires matching of ventilation to perfusion: 1 ventilated alveoli/ 1 blood perfused alveoli. Ventilation (V) / perfusion (Q) is not equal across the lung. Top of lung is poorly perfused. V / Q = 3.3 at top of lung. Bottom of lung has more perfusion than ventilation. V / Q = .63 at bottom of lung. V / Q values above .5 are generally adequate.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
