An Overview of the Respiratory System: Anatomy, Physiology, Assessment, and Abnormalities

Anatomy 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 …
Anatomy of Respiratory System  II: Lower Respiratory Tract
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and …
Physiology of Respiration I: Functions of the Respiratory System
The physiology of respiration involves three fundamental processes: ventilation, oxygenation, and the dynamics of compliance and resistance. Ventilation …
Physiology of Respiration II: Neurogenic Control of Respiration
The regulation of respiration is mediated by a cluster of neurons in the brainstem known as the respiratory centers. The respiratory centers are divided …
Physical Assessment of the Respiratory Tract I: Health History
A respiratory tract assessment helps identify and manage respiratory conditions by collecting both subjective and objective data. Subjective data is …
Physical Assessment of the Respiratory Tract II: Inspection
Inspection is the initial step in assessing the respiratory system. It involves observing the following components. Initially, the chest configuration is …
Physical Assessment of the Respiratory Tract II: Palpation
Palpation is a method of assessing the respiratory tract to detect tenderness, masses, lesions, respiratory excursions, and fremitus. First, the nurse …
Physical Assessment of the Respiratory Tract III: Percussion
Begin the percussion assessment by positioning the patient upright and leaning forward with arms folded for the posterior chest examination. Start …
Physical Assessment of the Respiratory Tract IV: Auscultation
Auscultation is a crucial method in respiratory assessment that provides vital information about airflow and lung obstructions. Begin by instructing the …
Respiratory System Abnormal Finding I: Inspection and Percussion
Inspection and percussion methods of examination help detect respiratory system abnormalities. Abnormalities detected during the inspection include the …
Respiratory System Abnormal Finding II: Palpation and Auscultation
In respiratory assessments, palpation can detect abnormalities such as tracheal deviation, suggesting conditions like tension pneumothorax or large …
Assessment of Pulmonary Capillary Blood Volume, Membrane Diffusing Capacity, and Intrapulmonary Arteriovenous Anastomoses During Exercise
Exercise is a stress to the pulmonary vasculature. With incremental exercise, the pulmonary diffusing capacity (DLCO) must increase to meet the increased …
Conducting Maximal and Submaximal Endurance Exercise Testing to Measure Physiological and Biological Responses to Acute Exercise in Humans
Regular physical activity has a positive effect on human health, but the mechanisms controlling these effects remain unclear. The physiologic and biologic …
Conducting Respiratory Oscillometry in an Outpatient Setting
Respiratory oscillometry is a different modality of pulmonary function testing that is increasingly used in a clinical and research setting to provide …
