Randomized trials have found that use of a pulmonary artery catheter did not influence the mortality of critically ill patients with shock or acute respiratory distress syndrome. Although measurement of right atrial central venous pressure Pra is a central component of early goal-directed therapy for septic shock, use of the Pra to guide hemodynamic management is controversial.

Hemodynamic instability, causing a mismatch between oxygen delivery and demand, is a major contributive factor for organ failure. Alterations in effective circulating volume e. We can often manage it with regular clinical examination and monitoring of certain basic vital parameters heart rate, blood pressure, central venous pressure [CVP], peripheral and central venous oxygen saturation, and respiratory variables and urine output, but when these fail there is an increased need for hemodynamic monitoring cardiac output [CO], pulmonary arterial occlusion pressure [PAOP or wedge pressure], pulmonary arterial pressure [PAP], mixed venous oxygen saturation [SvO 2 ], stroke volume variation [SVV], extravascular water, etc.

Arterial blood pressure ABPa basic hemodynamic index, is often used to guide therapeutic interventions in critically ill patients. Inaccurate ABP measuring may cause misdiagnosis and mismanagement. Because of a knowledge deficit related to hemodynamic and ABP monitoring, the authors discuss ABP physiology, factors that affect ABP, and the arterial pressure waveform and its interpretation in clinical situations. Arterial blood pressure ABP is a basic hemodynamic index often utilized to guide therapeutic interventions, especially in critically ill patients.

Telemetry is an observation tool that allows continuous ECG, RR, SpO 2 monitoring while the patient remains active without the restriction of being attached to a bedside cardiac monitor. Telemetry is not a replacement for patient visualisation and assessment. Telemetry accuracy relies on skin preparation, electrode and lead placement, equipment maintenance, patient monitoring and education.

Few operative procedures rival the complexity, invasiveness, and alteration of normal physiology observed during cardiac surgery. Many vital organ systems are influenced by the utilization of cardiopulmonary bypass CPBnecessitating comprehensive monitoring of the systems most affected. Clearly the anesthesia practitioner participating in cardiac surgical procedures must fully understand the sophisticated monitoring techniques that are commonly, if not universally, applied to the care of these patients.

In this section of the NCLEX-RN examination, you will be expected to demonstrate your knowledge and skills of hemodynamics in order to:. Simply defined, decreased cardiac output is the inability of the heart to meet the bodily demands. The normal cardiac output is about 4 to 8 L per minute and it can be calculated as:. Decreased cardiac output adversely affects the cardiac rate, rhythm, preload, afterload and contractibility, all of which can have serious complications and side effects.
