Dependent on central venous pressure (CVP) there were typical variations in the configuration, width and respiratory movements. These changes allowed a reliable estimation of the CVP. Decrease of the width in anteroposterior diameter in connection with a reduction of respiration-dependent caval movement indicated a deficiency of circulating blood volume. These alterations were always positive in cases of dehydration. Elongation of the vessel together with a widening over 2 cm and the lack of the normal end-inspiratory collapse were signs of an increased CVP. This non-invasive method is without risks or inconvenience for the patient. It is easily and quickly applied and very reliable for analyzing ICV haemodynamics.

In the population, that is between 70 and 79 years of age the proportion of patients in long-term medical care units increases twenty-fold. The present investigation is a part of the longitudinal population study of 70-year-olds who have been followed to 79 years of age in Göteborg. A representative sample of 79-year-old men and women has been investigated. At this age 8.7 per cent of the men and 8.3 per cent of the women were living in medical and social institutions. Institutionalization was defined as constant care outside the patient's home for at least three successive months at the time of the investigation. The percentage of men living in somatic long-term medical care facilities was 4.3, while for women it was 2.4. The corresponding figures for psychiatric long-term care were 1.9 per cent for men and 1.8 per cent for women. 1.9 per cent of the men and 3.7 per cent of the women had moved to old people's homes where the subjects are expected to manage their own daily activities. Among the institutionalized probands only 7 per cent of the women were married, while this was the case for 43 per cent of the men. The subjects in psychiatric long-term care had the longest nursing time, i.e. about 20 years, while in the other types of institutions this time was about 3 years.
