What is the characteristic of a healthy pregnant patient's breathing?

During pregnancy, a woman's body undergoes various physiological changes to support the developing fetus, including adaptations in respiratory function. A healthy pregnant patient typically experiences an increased rate and depth of breathing. This occurs as the body works to meet the heightened metabolic demands of both the mother and the growing fetus, which requires more oxygen and produces more carbon dioxide.

The increase in respiratory rate helps enhance ventilation, allowing for better oxygen exchange and efficient removal of carbon dioxide. Additionally, the increased depth of breath—sometimes referred to as "dyspnea on exertion"—is an adaptation that accommodates for the changes in lung capacity and the diaphragm's movement, as the growing uterus can push against the diaphragm, affecting lung function.

Thus, in the context of a healthy pregnant woman, the characteristic breathing pattern of increased rate and depth supports the overall health of both the mother and the fetus, ensuring adequate oxygen delivery throughout the pregnancy.
