Upper Respiratory Drugs: Decongestants01:27

Upper Respiratory Drugs: Decongestants

Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.
Most decongestants are readily available over-the-counter in various...
Nose and Nasal Cavity01:24

Nose 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...

Physical Assessment of the Respiratory Tract I: Health History

Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and key...

Drugs Used in Upper Respiratory Disorders: Overview01:16

Drugs Used in Upper Respiratory Disorders: Overview

Upper respiratory tract disorders, including viral infections and allergic rhinitis, cause significant discomfort and disrupt daily life. Managing these conditions involves a variety of drugs, such as antihistamines, intranasal steroids, decongestants, antitussives, expectorants, and mucolytics. Specific examples of drugs in each category are provided.
Antihistamines (e.g., Benadryl) block histamines from binding. Histamines are chemicals released during an allergic reaction in the body. As a...
Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features01:24

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Summary

This study clarifies the distinction between subjective "fullness" and objective "congestion" in nasal patency. It explores how nasal sensations relate to objective measurements, aiding in understanding allergic rhinitis.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Neuroscience

Background:

  • Subjective reports of nasal closure lack clear correlation with objective nasal patency measures.
  • Inconsistent terminology, like
  • congestion,
  • blurs the distinction between patient perception and physiological assessment.
  • Nasal sensations involve complex neural interpretations modulated by inflammation and plasticity.

Purpose of the Study:

  • To differentiate subjective nasal
  • fullness
  • from objective nasal
  • congestion
  • and evaluate their correlation.
  • To analyze the neural basis of nasal sensory perception in conditions like allergic rhinitis.
  • To review medical evidence for objective nasal patency assessment methods.

Main Methods:

  • Systematic review and analysis of medical evidence using the GRADE system.
  • Comparison of subjective patient-reported sensations with objective measurements (acoustic rhinometry, rhinomanometry, peak nasal inspiratory flow).
  • Exploration of neurophysiological mechanisms underlying nasal sensation.

Main Results:

  • Dilation of venous sinusoids is identified as a primary factor in regulating nasal airspace volume.
  • Neural plasticity and hyperalgesia contribute to heightened sensitivity to nasal stimuli.
  • The study provides a framework for correlating objective nasal airflow data with patient-reported sensations.

Conclusions:

  • Clearer terminology (
  • fullness
  • vs.
  • congestion
  • ) is crucial for accurate nasal assessment.
  • Understanding the neural integration of nasal stimuli is key to interpreting subjective sensations.
  • Objective measures, when correlated with patient perception, can improve the diagnosis and management of nasal conditions.
