Summary

  1. 1

    The present concept that the “norinal” arterial oxygen tension is 100 mm Hg may have to be altered In patients being prepared for elective surgical procedures, the average oxygen tension was 80 4 mm Hg

     
  2. 2

    In the immediate postoperative period, arterial hypoxaemia was present in all patients who were allowed to breathe room air At the sanje time, the pH and carbon dioxide tensions of the arterial blood were within normal limits

     
  3. 3

    Patients in the age group over 50 showed greater degrees of arterial hypoxaemia than those under 50

     
  4. 4

    The administration of oxygen by mask or nasal catheter postoperatively corrected the low arterial oxygen tensions All patients should receive oxygen in the postoperative period

     
  5. 5

    The most likely explanation for the arterial hypoxaemia is a disturbance in the ventilation-perfusion ratio in the lungs

Résumé

  1. 1

    Il faut changer le concept actuel que la tension “normae” de l’oxygène artériel est de 100 mm de mercure Chez les malades préparés pour la chirurgie élective, la tension moyenne de l’oxygène était de 80 4 mm de mercure

     
  2. 2

    Durant la période postopératoire immédiate, il y avait de l’hypoxémie artérielle chez tous les malades qui respiraient l’air de la pièce Au même moment, le pH et les tensions d’acide carbonique du sang art00E9;riel se tenaient dans les imites de la normale

     
  3. 3

    Les malades de plus de 50 ans ont présenté une hypoxémie artérielle plus mportante que ceux de moins de 50 ans

     
  4. 4

    L’administration d’oxygéne par masque ou cathéter nasal a corrigé les basses tensions d’oxygène artériel Tous les malades devraient recevoir de l’oxygène durant la période postopératoire

     
  5. 5

    L’explication la plus vraisemblable de cette hypoxémie artérielle est qu’il se produit un trouble dans le rapport ventilation-perfusion dans les poumons
