Sep 4, 2021 · Nasopharyngeal airways (NPAs) and oropharyngeal airways (OPAs) are basic components of a first aid kit. The NPA passes through the nose and extends to the back of the throat, creating a clear passage for air to enter the lungs. The OPA is inserted through the mouth.

An oropharyngeal airway (OPA) is also known as an oral airway or Guedel pattern airway or simply Guedel airway (named after the original designer Arthur Guedel). 2 The nasopharyngeal airway (NPA) is also called a nasal airway, NPAT (nasopharyngeal airway tube), or nasal trumpet.

Dec 4, 2024 · NPA and OPA are both essential tools in airway management, each with specific indications and contraindications. Understanding their differences, appropriate use cases, and insertion techniques is crucial for effective airway management.

Dec 2, 2021 · This type of airway has some advantages over the OPA as it can be used in a conscious, unconscious or semi-conscious patient since it doesn’t stimulate the gag reflex as an OPA does. Also, an NPA can be used in patients with mouth trauma, where an OPA can’t or shouldn’t be used.

Jul 29, 2024 · This article compares nasopharyngeal airways (NPA) and oropharyngeal airways (OPA) through their unique uses and applicable scenarios, allowing users to gain more knowledge about these airway management tools and helping them choose the most suitable product.

Mar 17, 2025 · The main difference between OPA and NPA lies in insertion site and patient tolerance: OPA is used for unconscious patients without a gag reflex, as it can trigger vomiting if used in alert individuals.

Jun 23, 2021 · To prevent tongue covering epiglottis in the patient with reduced Glasgow Coma Scale, an NPA is usually applied. NPAs are measured with the French catheter scale, but they are given in millimeters in terms of size quotation. The usual sizes of the NPA include 6.5mm/28FR, 7.0mm/30FR, 7.5mm/32FR, 8.0mm/34FR, and 8.5mm/36FR.

Sep 10, 2024 · Learn how to properly measure and use Oropharyngeal (OPA) and Nasopharyngeal (NPA) airways in airway management. This detailed guide covers measurement techniques, usage, and key differences to ensure effective and safe airway support.

Feb 19, 2025 · However, medical professionals often notice a key difference: NPAs are usually sterile, while OPAs are not. Why is this the case? This article explains the differences, use cases, contamination risks, and safety concerns of both devices. We will also introduce Bever Medical's NPA and OPA options.

The OPA is a J-shaped device that fits over the tongue to hold the soft hypopharyngeal structures and the tongue away from the posterior wall of the pharynx. OPA is used in individuals who are at risk for developing airway obstruction from the tongue or from relaxed upper airway muscle.
