Background: It is common for technicians to loudly coach the patient during pulmonary function tests (PFT) to increase patient accordance.

Aims:  We aimed to evaluate voice disorders in PFT technicians in our country.

Methods: Weekly working hours, the number of patients tested, and medical diagnoses related to voice were asked through the questionnaire using the online survey software program (SurveyMonkey©). Voice handicap index (VHI-10) and voice-related quality of life scale (VR-QOL) were applied.

Results: A total of 45 PFT technicians were reached. 82.2% of these were women. 13.3% had a medical diagnosis related to the voice, and 33.3% of these were diagnosed after they started to work. The mean working year in the PFT laboratory was 8.82 (±7.764). PFT technicians were required to shout/talk loudly for a mean of 22.98 (±16.954) hours per week. While the mean (VHI-10) score was 17.1 (±9.38471), VR-QOL was 17.2 (±8.79446). There was no statistically significant difference between the number of patients tested individually, the number of hours of shouting/loud talking per week, and the VHI-10 total score and the VR-QOL total score (p>0.05).

Conclusion: Although there is no exact predictive value for voice abuse, a VHI-10 score above 11 is considered abnormal. In conclusion, it is difficult to say that the sound quality of the PFT technicians is not affected. As far as we know, there has yet to be any previous study on the sound quality of PFT technicians. Tools such as high-visibility videos for patients and computer software that explain maneuvers and give commands can be used instead of "bad use of voice" to protect the voice health of technicians.
