Summary
Point of care ultrasound (POCUS) enhances airway management by confirming endotracheal intubation and identifying the cricothyroid membrane. This portable, non-invasive tool shows promise in improving the prediction of difficult airways.
Area of Science:
- Emergency Medicine
- Anesthesiology
- Critical Care Medicine
Background:
- Portable ultrasonography, or point of care ultrasound (POCUS), is increasingly used in perioperative care.
- POCUS offers portability, speed, and non-invasiveness, avoiding radiation exposure.
- Its application in airway management is being explored for improved patient care.
Purpose of the Study:
- To describe the technique and relevant anatomy for using POCUS in airway management.
- To review the use of POCUS for confirming endotracheal intubation.
- To detail the identification of the cricothyroid membrane for surgical airway procedures.
Main Methods:
- Describing the technique for ultrasound confirmation of endotracheal intubation.
- Illustrating relevant anatomy and ultrasonographic images.
- Reviewing the identification of the cricothyroid membrane and image acquisition.
Main Results:
- POCUS can confirm endotracheal intubation and identify the cricothyroid membrane.
- Ultrasonographic assessment has the potential to improve the accuracy of predicting difficult airways compared to traditional exams.
- Initial evidence suggests improved diagnostic accuracy for difficult airway prediction.
Conclusions:
- Airway POCUS is a valuable tool for airway management, offering improved diagnostic accuracy.
- Standardizing technical aspects and promoting further research are crucial due to operator dependency.
- The protocol aims to educate professionals and advance research in airway POCUS.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

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...

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

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...
