[Clinical lung function investigations in sheep].
In 144 clinical healthy and 97 sick sheep pneumotachographic investigations were performed. In 119 sheep the diagnoses "healthy" based on adspection, auscultation and palpatory percussion. In 25 additional healthy and in the sick animals the diagnoses based on clinical, endoscopical, serological, parasitological, and in 82 animals also pathomorphological findings. According to these diagnoses the animals were divided into the following groups: G = healthy, K = catarrhal purulent bronchopneumonia, E = suppurative pneumonia, W = verminous pneumonia, M = Maedi, MKE = Maedi + catarrhal purulent or suppurative pneumonia, MAKE = Maedi + Adenomatosis + catarrhal purulent or suppurative pneumonia, AKE = Adenomatosis + catarrhal purulent or suppurative pneumonia, and FAKE = animals of the AKE group at an earlier date of investigation. In all sheep respiration rate, tidal and minute volumes, forced tidal volume, peak flow and resistance were measured with the portable pneumotachograph Flowscreen. Tidal and minute volumes and flow rates depended at rest as well as after forced ventilation essentially from the respiratory rate and from the body weight of the animals. The average individual coefficients of variation of repeated measurements of healthy animals were between 21% and 36%. Only in tidal volume after forced ventilation (10%) and in the resistance (18%) the individual coefficients of variations were lower. In 57% of the animals with Lung Adenomatosis resistance-values over 0.4 kPa*s/l were measured, but in 94% of the sheep without adenomatosis resistance-values remained under this limit.
