AB  - Common pulmonary function tests used in man and domestic mammals were adapted to 
      the goat. Requirements for intrathoracic pressure record and pulmonary function 
      investigation were determined. The elastance of the mid-thoracic portion of the 
      oesophagus was measured in 17 healthy goats. The calculated percentage error in 
      identifying the endoesophageal intrathoracic pressure decreased with somatic 
      growth, and was found to be smaller than 2 per cent for adult goats. The location 
      of the oesophageal balloon catheter used to measure the intrathoracic pressure 
      was standardised. The following regression equation calculated between the length 
      of catheter (Lcat) and the thoracic circumference (TC) was found: Lcat (cm) = 
      6.19 +/- 0.7163 X TC (cm) (R2 = 0.96). The influence of the dead space of a face 
      mask on respiration pattern and arterial blood gas were studied. There were no 
      significant changes in arterial partial pressure of oxygen (PaO2) and carbon 
      dioxide (PaCO2), pHa, breathing frequency and intrathoracic pressures. The 
      influence of head and neck position was investigated. Upper airway resistance 
      (Ruaw), measured with the head in a normal position did not significantly differ 
      from values obtained with the head in a horizontal position. Ruaw measured with 
      the head in a vertical position was considerably increased. Arterial blood gas 
      tension and pulmonary mechanics were measured to assess the reproducibility of 
      pulmonary function measurements. Variability in blood gas tension, tidal volume 
      and minute volume is small. The variability of peak to peak intrathoracic 
      pressure change (max delta Plp), dynamic lung compliance (Cdyn), total pulmonary 
      resistance (RL) and Rt were relatively large.
