Study Notes

Respiratory System Functions

The respiratory system is responsible for gas exchange, but it is not responsible for absorbing nutrients.

Respiratory Tract

The part of the respiratory tract responsible for gas exchange is the alveoli.

Paranasal Sinuses

The main function of the paranasal sinuses is to warm, humidify, and filter the air we breathe.

Blood Supply

The Sphenopalatine foramen is supplied by the Sphenopalatine artery.

Sinusitis

The maxillary sinus is particularly prone to sinusitis.

Innervation

The Nasociliary nerve is innervated by the Ophthalmic branch of the Trigeminal nerve.

Nasal Cavity

The nasal cavity is divided into two parts: the nasal vestibule and the nasal cavity proper.
The nasal cavity warms, humidifies, and filters the air we breathe.

Nasal Hair (Vibrissae)

The function of nasal hair (vibrissae) is to filter the air we breathe.

Olfaction

The cranial nerve responsible for the sense of smell is the Olfactory nerve (Cranial Nerve I).
The Olfactory nerve supplies special sensory innervation to the olfactory epithelium in the superior portion of the nasal cavity.

Innervation of the Nasal Cavity

The Anterior Ethmoidal nerve supplies somatic sensory innervation to the anterior superior portion of the nasal cavity.
The Posterior Ethmoidal nerve supplies somatic sensory innervation to the postero-inferior portion of the nasal cavity.

Waldeyer's Ring

The most superior portion of Waldeyer's ring is composed of the Nasopharyngeal tonsil.

Tonsils

The Nasopharyngeal tonsil is commonly referred to as the adenoid.

Nasopharyngeal Carcinoma

The common name for the nasopharyngeal carcinoma is "cancer of the nose".

Upper Airway Obstruction

Stridor is a symptom of upper airway obstruction.

Clinical Features

A 'ruddy' complexion may indicate serious pathology, such as Polycythemia.
Horner's syndrome is characterized by a constricted pupil, drooping eyelid, and anhidrosis.

Respiratory Examination

The first step in the respiratory examination process is to inspect the patient's overall appearance.
The general inspection in respiratory examination includes observing the patient's posture, breathing pattern, and use of accessory muscles.
The technique used to assess the position of the trachea during palpation of the neck and chest is tracheal palpation.
A tension pneumothorax is a life-threatening emergency that presents with severe symptoms/signs of respiratory distress.

Percussion

A dull percussion note is associated with pleural effusion or haemothorax.

Vocal Resonance

The technique used to assess vocal resonance during a respiratory examination is vocal fremitus.
Increased vocal resonance can indicate consolidation or pleural effusion.
Decreased vocal resonance can indicate pneumothorax or pleural effusion.
Vocal resonance can be used to detect signs of respiratory pathology, such as consolidation or pleural effusion.
The purpose of comparing vocal resonance on both sides of the chest during a respiratory examination is to detect any asymmetry.
The recommended technique for assessing vocal resonance during a respiratory examination is to ask the patient to say "99" repeatedly.
