Oxygenation and Acid–Base Balance Monitoring
Figure 6-1 Relationship of alveoli and pulmonary capillaries. (From Patton KT, Thibodeau GA: Anatomy & physiology, ed 7, St. Louis, 2010, Mosby.) Blood Flow All of the blood ejected from…
Hemodynamic and Intracranial Dynamic Monitoring in Neurocritical Care
Figure 21-1 Hyperemia. Small volume increases in one or two of the intracranial contents can be tolerated with a reciprocal decrease in the other one or two volumes. This compensation…
Ultrasonography-Based Hemodynamic Monitoring
Patient Education Patients and families appreciate the hands-on approach that is needed for point-of-care ultrasonographic evaluations, and the interactions provide an opportunity for the understanding of the patient’s condition…
Venous Oxygen Saturation Monitoring

Hemodynamics of Mechanical Circulatory Support
Figure 15-1 Intra-aortic balloon pump (IABP) catheter correctly positioned in the thoracic aorta just below the left subclavian artery and above the renal arteries. Hemodynamic and Physiologic Effects of Intra-aortic…
Hemodynamics of Acute Right Heart Failure and Pulmonary Hypertension
Figure 18-1 Right ventricular anatomy. The RV architecture includes the intraventricular septum. The septum divides the two ventricles of the heart and is essential in the motion of ventricular contraction….
Hemodynamics of Mechanical Ventilation and Acute Respiratory Distress Syndrome
Figure 14-1 A, During spontaneous breathing, the intercostal muscles contract, and the diaphragm expands the thoracic cavity, creating negative intrathoracic pressure drawing air into the lungs. This negative pressure supports…
