Textbook Problem

A rapid and shallow ventilator pattern is called

A. hyperpnea.

B. apnea.

C. alveolar hyperventilation.

D. tachypnea.

Summary Introduction

Introduction:

The breathing rate in a normal individual is about 12-18 breaths per minute. The breathing rate is altered in case of any complexity in the functioning of the lungs. There are multiple types of breathing patterns, such as slow breathing or rapid breathing, deep breathing or shallow breathing and these have clinical importance in the diagnosis of diseases. One such pattern is rapid and shallow breathing, in which the breathing counts per minute increase.

Explanation

Justification/ Explanation for the correct answer:

Option (d) is tachypnea. Tachypnea is a condition where the breaths are rapid but not deep. This mainly occurs due to increased stiffness in the lungs, which generally occurs in pulmonary edema or in severe pneumonia. Edema is the condition when there is an excess of fluids trapped in the body tissues and in case of pneumonia, there is an inflammation of alveoli. Hence, option (d) is correct.

The explanation for the incorrect answers:

Option (a) is hyperpnea. Hyperpnea is the condition when there is an increase in the depth of breathing but the rate may be increased or may remain constant. The condition arises when there is a lack of oxygen, usually at higher altitude or in case of anemia. So, it is an incorrect option.

Option (b) is apnea...
