Peak Nasal Inspiratory Flow (PNIF) for Nasal Breathing Evaluation
Rui Xavier
Abstract:Measuring nasal airflow and nasal breathing has been a major goal of rhinology. Many objective methods for measuring nasal airflow or nasal airway resistance or dimensions provide valuable data but are time-consuming and require expensive equipment and trained technicians, thus making these methods less practical for clinical practice. Peak nasal inspiratory flow (PNIF) measurement is fast, unexpensive, non-invasive and able to provide an objective evaluation of nasal airflow in real-time. Unilateral PNIF meas… Show more
