Hemodynamic monitoring gives nurses information about the patient’s cardiac status and organ perfusion. This allows for the proper fluid intervention(restriction or resuscitation) to be taken.
It aids in making sure that the optimal amount of fluids are being received.
-Suboptimal fluid resuscitation may lead to low perfusion state.
-Overly-aggressive fluid resuscitation can lead to volume overload and heart failure exacerbation.
- Pulmonary Artery Catheters allow direct measurement of the cardiac output, stroke volume, pulmonary artery pressures and the mixed venous oxygen saturation. A disadvantage is the difficulty in interpretation of the waveforms and the lack of an understanding of the relevance of each variable obtained. This can lead to inappropriate intervention and adverse results. It is associated with increased mortality (Lavdaniti, 2008).
- Central Venous Pressure can determine whether a patient requires fluids or is well hydrated or even congested. It is dependent on venous return to the heart, right ventricular compliance, peripheral venous tone and posture. A disadvantage is that this method is unable to predict patient’s volume status and response to fluids. It is also invasive and requires insertion of a catheter into the patient’s large neck vein(Lavdaniti, 2008).
to define the learning curve for USCOM use by a non-echocardiograpically trained ICU nurse; and to compare CO measures between USCOM (as determined by the ICU nurse with no previous training in cardiac output assessment) and PAC (as inserted by a medical team), both by thermodilution and a modified Fick equation (Corley, Barnett, Mullany, Fraser, 2009, p. 1292).
