Case 1

The patient's alveolar ventilation was_____ or _______ventilation.

Summary Introduction

To review:

The given blank space in the statement, “The patient’s alveolar ventilation was___________ or __________ ventilation.”

Introduction:

Alveolar ventilation can be defined as the amount of air that reaches the alveoli of the lungs during each breath. Its function is to remove the carbon dioxide from the blood and to take oxygen to the body tissues. It happens because of the passage of the gases according to the concentration gradient.

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

Explanation

In the given case, the rise in the ventilation–perfusion ratio (V/Q) resulted in excessive blood loss due to trauma. Thus, the blood flow via the lungs decreased progressively and alveolar ventilation became physiologically ineffective. The surgery reversed the pathological process

There occurred a huge loss of blood from the injury site. This led to the increased ventilation-perfusion ratio because the blood flow is hampered...
