Pulmonary function values in healthy Holstein-Friesian calves. 1978

A L Kiorpes, and G E Bisgard, and M Manohar

Repeated pulmonary function testing was performed on six 4- to 6-week-old resting, nonanesthetized Holstein-Friesian calves (av weight 59 kg). Under study conditions, PaO2, PaCO2 and pH were 73.3 mm of Hg, 41.2 mm of Hg, and 7.42, respectively. Mean ventilatory values for the group were: minute ventilation, 13.1 L/min/m2., and respiratory rate, 27.3 breaths/minute. Measurements of pulmonary mechanics were performed while animals breathed spontaneously through a pneumotachygraph. Intrapleural pressure was estimated, using an esophageal balloon-catheter. Total pulmonary resistance was 3.1 cm of H2O/L/sec and dynamic pulmonary compliance was 0.15 L/cm of H2O. These values have not been reported previously in the calf but agreed well with predicted values derived from comparative studies in other species. Efficiency of intrapulmonary gas mixing was estimated, using a N2 washout technique, and results agreed favorably with values previously reported in the dog.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D008170	Lung Compliance	The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.

D005652	Functional Residual Capacity	The volume of air remaining in the LUNGS at the end of a normal, quiet expiration. It is the sum of the RESIDUAL VOLUME and the EXPIRATORY RESERVE VOLUME. Common abbreviation is FRC.	Capacities, Functional Residual,Capacity, Functional Residual,Functional Residual Capacities,Residual Capacities, Functional,Residual Capacity, Functional
D000403	Airway Resistance	Physiologically, the opposition to flow of air caused by the forces of friction. As a part of pulmonary function testing, it is the ratio of driving pressure to the rate of air flow.	Airway Resistances,Resistance, Airway,Resistances, Airway
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
