    BackgroundEarly mobilization of patients in the intensive care unit can be beneficial, but evidence is insufficient to indicate whether allowing patients with an indwelling pulmonary artery catheter to walk is safe.ObjectiveTo describe the physiological and emotional responses to ambulation in patients with heart failure and a pulmonary artery catheter.MethodsThis prospective, descriptive study included 19 patients with heart failure monitored with a pulmonary artery catheter in a cardiac intensive care unit. Each patient, accompanied by a nurse, walked with continuous observation of heart rate and rhythm and pulmonary artery tracing on a transport monitor. Pulmonary artery catheter position and waveform, arrhythmias, and perceived levels of exertion and fatigue were recorded before and after each walk. The distance ambulated was documented. One to 3 times per week, nurses administered a questionnaire addressing patients' sense of well-being.ResultsThe 19 patients had 303 walks (range, 1-68; median, 7). During 7 patient walks (2.4%), catheter migration of 1 to 5 cm occurred, but no arrhythmias or waveform changes were observed. Changes in exertion and fatigue were significant (P < .001, paired t test), but levels of both were minimal after walking. Patients expressed physical and emotional benefits of walking.ConclusionsThis study provides preliminary evidence that for hemodynamically stable patients with heart failure, ambulating with a pulmonary artery catheter is safe and enhances their sense of well-being. The presence of an indwelling pulmonary artery catheter should not preclude walking.
