Document Summary
Family members play a valuable role in the patient"s recovery and should be considered members of the health care team. The major needs of families of critically ill patients have been categorized as informational needs, reassurance needs, and convenience needs: lack of information is a major source of anxiety for the family. Hemodynamic monitoring refers to the measurement of pressure, flow, and oxygenation within the cardiovascular system. Both invasive and noninvasive hemodynamic measurements are made in the icu. Values commonly measured include systemic and pulmonary arterial pressures, central venous pressure (cvp), pulmonary artery wedge pressure (pawp), cardiac output/index, stroke volume/index, and oxygen saturation of the hemoglobin of arterial blood (sao2) and mixed venous blood (svo2). Cardiac output (co) is the volume of blood pumped by the heart in 1 minute. Cardiac index (ci) is the measurement of the co adjusted for body size. The volume ejected with each heartbeat is the stroke volume (sv).
