Nose and Nasal Cavity01:24

Nose and Nasal Cavity

11.7K
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

3.1K
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.

A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.6K
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.

Functional Groups02:45

Functional Groups

88.5K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Functionalism

2.6K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.
James envisioned psychology's...

Summary
This summary is machine-generated.

Treating nasal issues before continuous positive airway pressure (CPAP) therapy can improve long-term adherence for obstructive sleep apnea (OSA) patients. Early nasal evaluation and treatment are key for sustained CPAP use.

Area of Science:

  • Sleep Medicine
  • Otolaryngology
  • Respiratory Medicine

Background:

  • Continuous positive airway pressure (CPAP) is the primary treatment for obstructive sleep apnea (OSA).
  • Patient compliance with CPAP therapy is often inconsistent.
  • Nasal ailments, like congestion, are frequently cited as reasons for poor CPAP adherence.

Purpose of the Study:

  • To investigate the impact of nasal anatomical features and diseases on CPAP adherence in OSA patients.
  • To identify criteria for initiating nasal treatment before CPAP therapy.
  • To predict the need for pre-CPAP nasal interventions based on initial clinical data.

Main Methods:

  • Retrospective analysis of 711 adult OSA patients with an apnea-hypopnea index ≥20.
  • Evaluation of nasal parameters, medical history, symptoms, and disease severity.
  • Assessment of CPAP initiation, usage rates (initial and 1-year), and treatment continuation.

Main Results:

  • Higher nasal resistance correlated with early CPAP discontinuation.
  • Nasal disease and parameters did not predict 1-year adherence.
  • Predictors for nasal treatment included allergic rhinitis, severe congestion, sinus opacification, and nasal septum deviation.
  • Predictors for surgical treatment included awareness of congestion, prior sinusitis, and high nasal resistance.

Conclusions:

  • Initial CPAP adherence can predict long-term adherence.
  • Nasal factors significantly influence early CPAP discontinuation and require pre-emptive treatment.
  • Indications for pre-CPAP nasal treatment and surgery can be determined from initial examinations, guiding tailored patient management.
