Nose and Nasal Cavity01:24

Nose and Nasal Cavity

12.1K
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...

Administering Oxygen by Nasal Cannula

3.4K
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,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.7K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

    Summary
    This summary is machine-generated.

    Angiosarcoma, a rare vascular endothelial cancer, can occur in the nasal and sinus areas. Early detection is challenging due to hidden locations, but surgical excision and radiotherapy are effective treatments.

    Area of Science:

    • Oncology
    • Pathology

    Background:

    • Angiosarcoma, a rare malignant tumor originating from vascular endothelial cells, can manifest in various body parts.
    • While uncommon, angiosarcoma can affect the nasal and sinus regions, which are rich in blood vessels.

    Observation:

    • Nasal and sinus angiosarcomas present subtly, often with symptoms like nasal bleeding, congestion, and headaches.
    • The hidden anatomical location and non-specific symptoms contribute to delayed diagnosis.

    Findings:

    • This rare tumor type is difficult to detect early due to its insidious presentation.
    • Complete surgical excision combined with radiotherapy is the primary treatment for localized nasal and sinus angiosarcoma.

    Implications:

    • Improved diagnostic strategies are needed for earlier detection of nasal and sinus angiosarcomas.
    • Timely and appropriate treatment can improve outcomes for patients with this rare malignancy.
