Acid-base disorders in status asthmaticus (author's transl)

Bulletin De Physio-pathologie Respiratoire

In 85 patinets withstatus asthmaticus, the authors have studied the acid-base balance, the blood gas tensions and various humoral parameters. The values were classified into two groups according to the PaCO2 level: below or equal to 44 torr (Group I), higher than 44 torr (Group II). In the 58 cases of Group II, there was a very close positive correlation between PaCO2 and H + ions, practically the same as that established by BRACKETT et al. [3] in experimental acute hypercapnia in man. On the contrary, the correlation derived from cases of status asthmaticus in the literature showed, in some cases, a metabolic component in acidosis. In the present work, the mean value of lactates was close to normal; there was a slow increase in protein content and hematocrit, in the two groups. The prognosis of the status asthmaticus depends on the degrees of hypercapnia: when it reaches 70 torr, mechanical ventilation is urgently needed and is the main part of the treatment; the use of additional drugs remains a matter of specific case.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.


This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.
