Airway obstruction is a blockage of respiration in the airway that hinders the free flow of air. Airway obstructions can occur either in the upper airway or lower airway . The upper airway consists of the nose, throat, and larynx.
This can lead to parts of the lung having a honeycomb-like appearance. The extrinsic causes result in lung restriction, impaired ventilatory function, and even respiratory failure due to the diseases that effect the lungs ability to create a change in lung volumes during respiration due to the diseases of the systems stated above.

Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents . [ citation needed ] Airway management is commonly divided into two categories: basic and advanced .
In obstructive lung disease, the FEV1 is reduced due to an obstruction of air escaping from the lungs. Thus, the FEV1/FVC ratio will be reduced. [4] More specifically, according to the National Institute for Clinical Excellence, the diagnosis of COPD is made when the FEV 1 /FVC ratio is less than 0.7 or [8] the FEV 1 is less than 75% of predicted; [9] however, other authoritative bodies have ...
Extrapulmonary restriction is a type of restrictive lung disease, indicated by decreased alveolar ventilation with accompanying hypercapnia. It is characterized as an inhibition to the drive to breathe, or an ineffective restoration of the drive to breathe.
For nasal obstruction, options can be septoplasty, turbinate reductions, or surgical palate expansion. [2] Orthognathic surgeries that expands the airway, such as Maxillomandibular advancement (MMA) or Surgically Assisted Rapid Palatal Expansion (SARPE) are the most effective surgeries for sleep disordered breathing.
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
