title: [Spirometry parameters of women in various positions of delivery].
abstract: Position in labour depends mostly on women's preferences, and is chosen instinctively in order to reduce labour pain. Between two different positions: vertical and horizontal, the first of them seems to guarantee more convenient gas exchange in maternal lungs.
  
  
  METHODS
  To prove that the vertical position in labour increase spirometry parameters in comparison with horizontal one.
  
  
  METHODS
  Women were divided into two groups according to position in labour and spirometry examination were performed in second period of labour. Group I were composed of 17 women in vertical position whereas group II--19 women in horizontal one.
  
  
  RESULTS
  Whole of analysed spirometral parameters had higher values in group I (8.2%-17.1%), but the increase wasn't statistically significant (p < 0.05).
