Introduction.
The aim of the study was to compare the breath-holding test and single-breath carbon dioxide test in evaluation of the peripheral chemoreflex sensitivity to carbon dioxide in healthy subjects of different age.
Methods.
The study involved 47 healthy volunteers between ages of 25 and 85 years.
All participants were divided into 4 groups according to age: 25 to 44 years (n=14), 45 to 60 years (n=13), 60 to 75 years (n=12), and older than 75 years (n=8).
Breath-holding test was performed in the morning before breakfast.
The single-breath carbon dioxide (SB-CO2) test was performed the following day.
Results.
No correlation was found between age and duration of breath-holding (r=0.13) and between age and peripheral chemoreflex sensitivity to CO2 (r=0.07).
In all age groups there were no significant differences in the mean values from the breath-holding test and peripheral chemoreflex sensitivity tests.
In all groups there was a strong significant inverse correlation between breath-holding test and SB-CO2 test.
Conclusion.
A breath-holding test reflects the sensitivity of the peripheral chemoreflex to carbon dioxide in healthy elderly humans.
Increasing age alone does not alter the peripheral ventilatory response to hypercapnia.
