Chapter 8, Problem 1CAQ1

Summary Introduction

To review:

The result of the continuous loss of blood on the alveolar ventilation of the patient.

Introduction:

Ideally, the alveoli in the lungs need to receive an equal amount of ventilation and blood flow; however, this is not possible because the ventilation is about 4 L/min (liter per minute) and the capillary blood flow is 5 L/min. This ratio of ventilation to perfusion is referred to as ventilation–perfusion ratio (V/Q).

Please refer to Clinical Application Case-1 for further information.
