Fig. 17. Cannon v waves. An incompetent tricuspid valve (tricuspid regurgitation) abolishes the x descent and causes cannon v waves as volume from the right ventricle backflows into the right atrium during ventricular systole. CVP, central venous pressure; ECG, electrocardiogram. S1, heart sound 1; S2, heart sound 2.

Fig. 18. Pulmonary artery catheter. A diagram of a typical pulmonary artery catheter with continuous cardiac output and mean venous oxygen saturation monitoring capabilities. Notice the addition of the thermal coils, thermistors, and optical components to the catheter. CVP, central venous pressure; PA, pulmonary artery; RV, right ventricle; SVO2, venous oxygen saturation.

Essentials of Human Physiology

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
