The nose, pharynx, and trachea are the parts of the upper airway. The tubes of the lungs comprise the lower airway.
Structures not found in the upper airway include the trachea, bronchi, and alveoli, which are part of the lower airway. The upper airway primarily consists of the nasal cavity, pharynx, and larynx. Additionally, structures such as the lungs and diaphragmatic muscles are also absent from the upper airway.
Stridor is commonly associated with conditions that cause airway obstruction, such as croup, epiglottitis, and foreign body inhalation. It is a high-pitched, inspiratory sound that occurs due to turbulent airflow through a partially obstructed airway. Treatment depends on the underlying cause and may include medications, positioning, or in severe cases, airway management procedures.
The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.
The trachea is the main airway in the human body. It carries air from the larynx to the bronchi in the lungs, allowing for breathing and gas exchange.
The trachea is the primary airway in the respiratory system, connecting the larynx to the bronchi. It is responsible for carrying air to and from the lungs during breathing.
Structures not found in the upper airway include the trachea, bronchi, and alveoli, which are part of the lower airway. The upper airway primarily consists of the nasal cavity, pharynx, and larynx. Additionally, structures such as the lungs and diaphragmatic muscles are also absent from the upper airway.
The glottis is dividing line between the upper and lower airway
The upper airway is composed of the nasal passages, nasopharynx, mouth and oropharynx, and the hypopharynx. Basically, everything above the glottis is upper airway, everything below is lower airway.
thyroid
Compromised neonate is a medical term used to describe an airway that is restricted or blocked. This can either be in the upper airway or the lower airway.
wheezing
The Heimlich maneuver.
TONGUe
laboured or no signs of breathing/Choking.
rhonchi
some say the vocal cords (glottis) or others say a line of cartilage.
