Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

967
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:...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.3K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

817
Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask...

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:

Epistaxis01:30

Epistaxis

358
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...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

383
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Summary

Face masks can cause the Koebner phenomenon, a skin condition, due to friction from tight ear loops. This case highlights a novel trigger for this dermatological response during the COVID-19 pandemic.

Area of Science:

  • Dermatology
  • Infectious Disease Epidemiology

Background:

  • The Koebner phenomenon, or isomorphic response, describes skin lesions appearing at sites of trauma.
  • Face masks became ubiquitous for COVID-19 prevention, introducing novel forms of physical stress.

Discussion:

  • This case report details Koebner phenomenon specifically induced by the friction of tight face mask ear loops.
  • The constant pressure and rubbing from mask wear acted as the koebnerizing stimulus.

Key Insights:

  • Friction from personal protective equipment (PPE) can be a trigger for the Koebner phenomenon.
  • This highlights the importance of considering PPE fit and material in dermatological adverse events.

Outlook:

  • Further investigation into PPE-induced dermatoses is warranted.
  • Recommendations for mask use should include awareness of potential skin trauma and appropriate fit.
