Cardiac Output
An investigation conducted by Nilsson et al. (2004) included 80 patients who each had eight consecutive measurements of cardiac output (in L/min) taken (except for a single patient where one observation is missing for technical reasons). One additional measurement was deleted because of an obvious error in measurement. The main purpose of the study was to determine the precision of the measurements, and in particular to see whether this precision could be related to covariates. Variable list: person: Identification number for the patient (to keep track of the 8 measurements on the same individual) gender: Gender of the patient 0: Female 1: Male age: Age of the patient weight: Weight of the patient height: Height of the patient pacemake: Does the patient use pacemaker? 0: No 1: Yes hr: Heart rate serialno: The serial number indexing the eight consecutive measurements for each patient cardout: The cardiac output measured
