Assessment of Airway, Skin Color, and Use of Accessory Muscles01:30

Assessment of Airway, Skin Color, and Use of Accessory Muscles

1.2K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...

Cardiopulmonary Resuscitation II: ACLS Airway Management

198
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Breathing01:05

Breathing

60.9K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Deglutition01:25

Deglutition

2.9K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Suctioning the Oropharyngeal Airway

472
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

1.3K
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.

Area of Science:

  • Anatomy
  • Physiology
  • Pediatrics

Background:

  • The concept of simultaneous breathing and swallowing in infants was popularized by Crelin and Laitman.
  • This idea suggests distinct anatomical pathways allowing newborns to breathe and swallow concurrently.
  • The propagation of this concept has persisted despite contradictory evidence.

Purpose of the Study:

  • To critically evaluate the primary research supporting simultaneous infant breathing and swallowing.
  • To investigate the reasons behind the widespread acceptance of this physiologically illogical concept.
  • To address the potential negative clinical consequences stemming from this misconception.

Main Methods:

  • Review of the seminal research article by Crelin and Laitman.
  • Analysis of cited data for misrepresentations and inaccuracies.
  • Examination of the persistence of the concept in scientific and popular literature.

Main Results:

  • The primary research article supporting simultaneous breathing and swallowing was found to be unconvincing.
  • Significant misrepresentations of prior data and self-presented data were identified.
  • The concept has been widely disseminated in literature and online, persisting into the 21st century.

Conclusions:

  • Newborns are physiologically incapable of simultaneous breathing and swallowing.
  • The continued propagation of this myth may have negative clinical implications for infant care.
  • A lack of comprehensive newborn anatomy education may contribute to the persistence of this misconception.
