CALDERON-ALEGRE, Pierina; MEJIA, Christian R  and  GOMERO-CUADRA, Raúl. Utility of facial anthropometry in selecting respirator size: a pilot study in civil construction workers. Rev Med Hered [online]. 2019, vol.30, n.3, pp.157-162. ISSN 1018-130X.

Facial anthropometric features are used to predict the size of respirators in workers exposed to inhalatory chemical products. However, the multiracial features of the Peruvian population has not been taken into account in this process. Objective: to determine whether the use of facial anthropometric measurements is useful to select the size of half-face respirators in civil construction workers. Methods: A cross-sectional study was conducted in 117 workers in whom the length of the face and widening of the mouth was used to determine the size of three half- face respirators. Results: Mean length of face was 12.2 ± 0.6 cm and mean of mouth widening was 5.3 ± 0.6 cm. After performing adjustment, only brand A passed the evaluation, the B and C brands had difficulties in adjusting to several variables. Conclusion: Facial anthropometric features can be used to select the size of respirators.
