Resumen

Se estudia la respuesta del centro respiratorio a un estímulo progresivo de C02, mediante el metodo de rebreathing en tres grupos de sujetos: normales, bronquíticos crónicos y asmáticos.

La diferencia en la respuesta ventilatoria en relación al incremento de CO2 fue significativa entre sujetos normales y asmáticos, así como entre asmáticos y bronquíticos. Por otro lado el incremento de P 0,1 en relación al incremento de CO2 separa claramente los normales de los bronquíticos, así como asmáticos de bronquíticos, y parece ser un buen reflejo del impulso neuromuscular central.

Summary

The respiratory center response to Progressive C02 stimuli was measured in three groups of subjects: healthy ones, patients with chronic bronchitis and asthmatic patients.

The difference in respiratory response to increased CO2 was significant between normal and asthmatic subjects and between asthmatic and bronchitic patients.

The increase in P 0.1 in response to increased CO2 clearly differentiates normal subjects from bronchitic ones and asthmatic ones from bronchitic subjects and seems to be a good indication of the central neuromuscular impulses.
