Correlação entre o pico do fluxo inspiratório nasal (PFIN) e o pico do fluxo expiratório (PFE) em crianças e adolescentes

Abstract

Objective: To review the most important papers published on the main available tests to obtain objective values of nasal patency and to demonstrate the practical aspects related to its use in routine care. Methods: Was accomplished a not systematic review in MEDLINE and LILACS databases, selecting the most relevant references. Results: Values are desirable goals, and are important in epidemiological studies, and monitoring of patients with nasal obstruction. There isa wide variety of objective tests of nasal function, acoustic rhinometry,rhinomanometry and peak nasal inspiratory flow (PFIN) are currently the most used tests. Conclusion: The choice use of available technologies depends on the reality of each service. The PNIF has been touted as an alternative simple and reliable, through which it is possible to obtain results easier to interpret, being an attractive method for clinical practice.
