OBJECTIVE To determine the intrarater and interrater reliability of cirtometry (measurements of the circumference of the chest and abdomen taken during respiratory movements) as well as its correlation with pulmonary volumes measured by respiratory inductive plethysmography. METHODS A total of 40 healthy individuals were evaluated. The mean age was 28 years. The measurements were taken in the...

The significance of strain gauge plethysmography and photoplethysmography in the diagnostics hemodynamic disturbance primary varicose veins is discussed. Both methods have ability to measure volume changes induced by calf pump activity quantify pre-treatment disorders, immediate post-treatment improvement, as well deterioration occurring during follow up. most frequently used parameters are ref...

The purpose of this study was to measure several variables associated with respiratory function at repeated intervals. The temporal variation of these variables was assessed within persons and within the sample population. Twenty-nine children, 18 boys and 11 girls, between the ages of 7 and 13 years of age, participated. Each subject attended three separate appointments. At each appointment, t...

Methods of indirectly determining blood pressure in the rat are reviewed and their drawbacks noted. A new method is described which has the advantage of objectivity and provides permanent graphic record of each determination. The end point used is the reappearance of pulsation in the foot distal to a slowly deflating leg cuff. Application of the method is described and its use compared with tai...
