Summary
The nasal cycle in healthy children is typically irregular, with variations observed between genders. This study monitored nasal airflow in adolescents, finding no correlation between cycle regularity and growth.
Area of Science:
- Otolaryngology
- Pediatric Physiology
- Respiratory Medicine
Context:
- The nasal cycle, a physiological phenomenon of alternating congestion and decongestion in the nasal cavities, is well-documented in adults.
- Understanding the nasal cycle in children is crucial for diagnosing and managing pediatric nasal conditions.
- Previous research has primarily focused on adult nasal cycle characteristics.
Purpose:
- To investigate the characteristics of the nasal cycle in healthy children aged 11-17 years.
- To analyze potential differences in nasal cycle patterns between boys and girls.
- To assess the relationship between nasal cycle regularity and physical growth in adolescents.
Summary:
- Ten healthy children (5 boys, 5 girls) aged 11-17 years underwent 7-hour nasal monitoring using a Rhinocycle rhinoflowmeter.
- The nasal cycle was characterized by fluctuations in relative volumetric flux (RVF); it was generally irregular with a mean fluctuation rate of 1.3+/-0.6 hours.
- While most children showed no significant RVF difference between nasal cavities, girls exhibited partially coinciding and fluctuating cycles, whereas most boys displayed irregular, bilateral, and fluctuating patterns. Cycle regularity did not increase with age.
Impact:
- This study provides normative data on pediatric nasal cycle physiology, aiding in the interpretation of nasal airflow studies in children.
- Findings suggest potential sex-based differences in nasal cycle dynamics during adolescence.
- The results indicate that nasal cycle patterns in children are established and do not significantly change with growth during the studied age range.

01:24Nose and Nasal Cavity
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...
01:29Anatomy of Respiratory System I: Upper Respiratory Tract
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

01:17Pulmonary Cycle: Exhalation
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...
01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:30Application of Integration: Problem Solving
The process of breathing involves the periodic intake and expulsion of air, known as the respiratory cycle, which typically lasts about five seconds. Modeling the volume of air inhaled into the lungs as a function of time provides insight into both the dynamics and efficiency of pulmonary ventilation. This volume is determined by integrating the airflow rate over time, which captures the cumulative effect of air entering the lungs.Sinusoidal Model of AirflowAirflow during respiration is not...
01:26Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
