Textbook Problem

If a patient weighs 175 pounds and has a tidal volume of 550 mL and a respiratory rate of 17 breaths/min, what is the patient’s minute alveolar ventilation?

Summary Introduction

To review:

The minute alveolar ventilation of a patient weighing 175 pounds with a tidal volume of 550 mL and a respiratory rate of 17 breaths/min.

Introduction:

The ventilatory pattern consists of the tidal volume (VT), the ventilatory rate, and the time relationship between inhalation and expiration. The inspired air that reaches alveoli in the lungs is effective in terms of gas exchange and the inspired gas portion is referred to as alveolar ventilation. The volume of inspired air that does not reach the alveoli and is not effective is known as dead space ventilation.

Explanation

The minute alveolar ventilation (VA) of the patient is equal to the tidal volume (VT) minus the dead space ventilation volume (VD), multiplied by breaths per minute:

VA=(VTVD)×breaths/min

The volume of the anatomical dead space is equal to 1 mL/lb of the ideal body weight of the patient.

The weight of the patient = 175 poundsSo, the dead space ventilation volume of the patient (VD) = 175 mL
