OP airways in varying sizes Oral pharyngeal airway (OPA) insertion. The correct size OPA is chosen by measuring from the first incisors to the angle of the jaw. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and ...
For human use, tubes range in size from 2 to 10.5 mm in internal diameter (ID). The size is chosen based on the patient's body size, with the smaller sizes being used for pediatric and neonatal patients. Tubes larger than 6 mm ID usually have an inflatable cuff. Originally made from red rubber, most modern tubes are made from polyvinyl chloride ...
Oropharyngeal airways in a range of sizes. Oropharyngeal airways are curved, rigid plastic devices, inserted into the patient's mouth. Oropharyngeal airways are produced in various lengths and diameters to accommodate for gender and anatomical variations. It is especially useful in patients with excessive tongue and other soft tissues.
The size is chosen based on the patient's body size, with the smaller sizes being used for infants and children. Most endotracheal tubes have an inflatable cuff to seal the tracheobronchial tree against leakage of respiratory gases and pulmonary aspiration of gastric contents, blood, secretions, and other fluids.
The French scale measures the outer diameter of the catheter, not the size of the internal drainage channel (inner diameter). For instance, a two-way catheter of 20 Fr and a three-way catheter of 20 Fr have the same outer diameter, but the three-way catheter has an additional channel for irrigation, reducing the size of its drainage channel.
Oropharyngeal airways are one of several different blind insertion airway devices. A blind insertion airway device (BIAD or blind insertion device) is a medical device used for airway management that ensures an open pathway between a patient's lungs and the outside world, as well as reducing the risk of aspiration, which can be placed without visualization of the glottis.

A nasopharyngeal airway inserted in the right nostril of a patient. The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. [10] The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. [5]
