Study Notes
Lung Auscultation Terms
-
Anterior: Refers to the front of the body or structures, opposite of posterior; essential in positioning during examinations.
-
Auscultation: The medical practice of listening to internal sounds, such as those of the heart and lungs, using a stethoscope for diagnostic purposes.
-
Bronchial: Pertains to the bronchi, the main air passages from the trachea to the lungs; important for understanding respiratory pathology.
-
Crackle: An abnormal lung sound detected during auscultation, indicating fluid in the airways or sudden opening of collapsed airways; categorized as fine or coarse and occurs during inspiration or expiration.
-
Expiration: The process of exhaling; involves diaphragm relaxation and thoracic cavity pressure increase, causing air to be expelled from the lungs.
-
Inspiration: The inhalation phase where the diaphragm contracts and thoracic cavity volume expands, lowering pressure and allowing air to flow into the lungs.
-
Posterior: Refers to the back of the body or structures, important for anatomical orientation during examinations.
Respiratory System Overview
-
Structure: The respiratory system’s primary organs are the two lungs, located in the thoracic cavity beside the heart; these organs are protected by the rib cage.
-
Diaphragm Function: This muscle plays a crucial role in respiration by helping to control the air pressure within the thoracic cavity and facilitating airflow into and out of the lungs.
-
Pleural Membranes and Fluid: These structures allow for smooth movement of the lungs within the thoracic cavity during breathing, essential for efficient respiratory function.
Diagnostic Tools
- Stethoscope: A medical instrument designed to amplify low-volume body sounds, such as heartbeats and intestinal noises, aiding in the assessment of health status.
Abnormal Lung Sounds
- Wheeze: A high-pitched sound produced during breathing, often indicating airway obstruction; can occur during both inhalation and exhalation, signaling respiratory distress.
