Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.8K
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...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

3.9K
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.

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

5.7K
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....

Epistaxis01:30

Epistaxis

626
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

3.6K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

7.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

    • To review the various causes of nasal obstruction.
    • To discuss the impact of allergic rhinitis (AR) on quality of life, sleep, and work efficiency.
    • To outline available medical and surgical treatment options for nasal obstruction.

    Main Methods:

    • Literature review of causes and treatments for nasal obstruction.
    • Discussion of persistent allergic rhinitis (AR) as a common etiology.
    • Exploration of treatment choices considering patient compliance and quality of life.

    Main Results:

    • Nasal obstruction has diverse etiologies, often multifactorial.
    • Allergic rhinitis (AR) significantly affects daily life, sleep, and work.
    • Various medical and surgical interventions exist for managing nasal obstruction.

    Conclusions:

    • Effective management of nasal obstruction requires addressing underlying causes like AR.
    • Treatment strategies must consider patient compliance and impact on quality of life.
