Suctioning the Nasopharyngeal Airway01:29

Suctioning the Nasopharyngeal Airway

6.5K
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.

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

958
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

13.9K
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

5.8K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Oxygen Delivering System III: Tracheostomy and T-piece

9.5K
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Cardiopulmonary Resuscitation II: ACLS Airway Management

1.2K
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...

Area of Science:

  • Anesthesiology
  • Emergency Medicine
  • Critical Care

Background:

  • Extraglottic airway devices (EADs) are common but often have poor seals, leading to leaks.
  • Optimal EAD size selection is critical for effective and safe airway management.
  • This review examines EAD sizing recommendations to guide optimal device selection.

Purpose of the Study:

  • To delineate sizing recommendations for extraglottic airway devices (EADs).
  • To identify differences in sizing guidelines to aid optimal device choice.
  • To enhance EAD effectiveness and patient safety through proper sizing.

Main Methods:

  • Searched manufacturer guidelines for EAD size recommendations.
  • Conducted a literature search for alternative EAD size selection suggestions.

Main Results:

  • Manufacturers offer a wide range of EAD sizes, often based on weight, but sometimes on age, gender, or height.
  • Specialized formulas and methods exist to aid in selecting the optimal EAD size, particularly for pediatric patients.
  • Novel 'one-size-fits-all' adult EADs have been introduced.

Conclusions:

  • EAD size selection is critical but controversial due to differing recommendations and lack of a universal system.
  • Effective EAD use depends on correct sizing, clinical judgment, and patient-specific anatomy/physiology.
  • Standardization and consensus on EAD sizing would improve clinical practice and patient safety.
