Ambulatory impedance cardiography in hypertension: a validation study.

The management of hypertension is improved by knowledge of the hemodynamics underlying blood pressure. Impedance Cardiography (ICG) provides data on a range of hemodynamic variables that affect blood pressure. However, ICG captures only fixed descriptions of hemodynamic characteristics.

Ambulatory impedance cardiography: a systematic review.

Background: Standard noninvasive impedance cardiography has been used to examine the cardiovascular responses of individuals to a wide range of stimuli in critical care and laboratory settings. It has been shown to be a reliable alternative to invasive thermodilution techniques and an acceptable alternative to the use of a pulmonary artery catheter. Ambulatory impedance cardiography provides a similar assessment of cardiac function to standard noninvasive impedance cardiography, but it does so while individuals engage in activities of daily living.

Enhancing postoperative recovery of cardiac surgery patients: a randomized clinical trial of an advanced practice nursing intervention.

The purpose of this trial was to determine the effectiveness of advanced practice nursing support on cardiac surgery patients' during the first 5 weeks following hospital discharge. Patients ( N = 200) were randomly allocated to two groups: (a) an intervention group who received telephone calls from an advanced practice nurse (APN) familiar with their clinical condition and care needs, twice during the first week following discharge then weekly thereafter for 4 weeks, and (b) a usual care group. Measures of health-related quality of life (HRQL), symptom distress, satisfaction with recovery care, and unexpected health care contacts were obtained at 5 weeks following discharge.
