In a state of hypercapnia, the accumulation of carbon dioxide in the blood causes the pH of the blood to drop, leading to a state of respiratory acidosis.

An artery is a blood vessel that carries blood away from the heart, where it branches into ever-smaller vessels. Eventually, the smallest arteries, vessels called arterioles, further branch into tiny capillaries, where nutrients and wastes are exchanged, and then combine with other vessels that exit capillaries to form venules, small blood vessels that carry blood to a vein, a larger blood vessel that returns blood to the heart.

The body attempts to compensate when changes occur due to illness or injury, but problematic symptoms might require urgent intervention. Understanding respiratory system disorders, oxygenation, and perfusion is crucial for effective nursing care. Nursing assessment allows for close monitoring of respiratory issues in patients.

It explains how these structures function together to maintain cardiovascular health. Key concepts like cardiac output, stroke volume, preload, and afterload are defined, with emphasis on their roles in the heart's mechanical and physiological processes.

It explains how the respiratory system provides oxygen to the body, removes carbon dioxide, and maintains acid-base balance. Key structures involved include the conducting zone (nose, pharynx, trachea) and respiratory zone (alveoli).

It is best to examine the precordium with the patient supine because if the patient is turned on the left side, the apical region of the heart is displaced against the lateral chest wall, distorting the chest movements.
