These two cases are interesting because of their rarity and uncommon presentation. [ncbi.nlm.nih.gov]

However, early presentations, with symptoms of upper airway obstruction in childhood, have been reported [1]. The majority of cases present with obstructive symptoms. [academic.oup.com]

• Unconsciousness

  RECOGNIZE COMMON CAUSES OF UPPER AIRWAY OBSTRUCTION An object lodged in the airway of a casualty who is conscious can result in unconsciousness, clinical death, and biological death. [nursing411.org]

  Continue alternating five back blows and five abdominal thrusts until successful or the patient becomes unconscious. In an unconscious patient: Lower the patient to the floor. Call an ambulance immediately. [patient.info]

  If the patient becomes unconscious, support the patient carefully to the ground. Immediately call an ambulance and begin CPR. Feel for a carotid pulse and initiate chest compressions even if a pulse is present in the unconscious choking patient. [gponline.com]

  Unconscious Victims [ edit ] Send a bystander to activate the Emergency Medical System if possible. [en.wikibooks.org]

• Hypoxemia

  Pulse oximetry is a poor indicator of airway compromise; a decreasing arterial hemoglobin oxygen saturation is a late sign of impending hypoxemia. Basic airway maneuvers improve the patency of an obstructed airway. [ncbi.nlm.nih.gov]

  Hypoxemia upon exercise has been reported in a series of seven patients secondary to alveolar hypoventilation. 6 Exertional hypoxemia in a patient with a normal diffusion capacity is reflective of alveolar hypoventilation that calls for further workup [rtmagazine.com]

   In severely affected patients, cor pulmonale may occur as a result of chronic hypoxemia and hypercarbia.  Typically, significant anatomic obstruction precedes overt symptoms. [slideshare.net]

  A compromised airway presents a significant hazard to any form of anaesthesia, especially if it results in cardio-respiratory depression, which will expedite hypoxemia and impair tissue oxygenation. [bjmp.org]

  The fraction of inspired oxygen in Heliox may be increased to as much as 40 percent to address concurrent hypoxemia. [pulmonologyadvisor.com]

• Fishing

  Fish et al observed that airway obstruction in asthma behaves as if it were caused by an inability of DIs to dilate constricted airways, as opposed to an increased responsiveness of the airway itself [ 5 ]. [respiratory-research.biomedcentral.com]

  Another hazard adults encounter while eating is bones from meat, such as chicken or fish. Treatments for Throat Obstructions The most common internal throat obstructions cause snoring and require one or more of many treatment options. [naturalremedies.org]

  The number of potential triggers is extensive; ingestion of peanuts, tree nuts, shellfish, fish, milk, and eggs is most commonly reported. [pulmonologyadvisor.com]

• Weight Gain

  We present four patients (1.6-4.1 kg, 32-41 weeks gestation) with nonspecific symptoms (e.g., poor weight gain, difficulty weaning from CPAP) who underwent bronchoscopy in the neonatal period. [ncbi.nlm.nih.gov]

• Weight Loss

  He has otherwise been healthy, although he did have a 15 lb unintentional weight loss. He denies hemoptysis, fevers, chills, or night sweats. There is no history of lung cancer in his parents or siblings. [clevelandclinicmeded.com]

• Cough

  For the conscious patient with an apparent partial obstruction, encourage him or her to cough. NOTE: In cases where the patient has an apparent partial obstruction but cannot cough, begin to treat the patient as if this were a complete obstruction. [medical.tpub.com]

  Children [ 3 ] If coughing effectively, just encourage the child to cough, and monitor continuously. If coughing is, or is becoming, ineffective, shout for help and assess the child's conscious level. [patient.info]

  Management • If coughing effectively, just encourage the child to cough, and monitor continuously. • If coughing is, or is becoming, ineffective, shout for help and assess the child's conscious level. • If the child is conscious, give up to five back [slideshare.net]

• Stridor

  As the plane gained elevation, the mass would grow and cause him to become stridorous and short of breath. The shortness of breath and stridor would only resolve upon landing of the plane. [ncbi.nlm.nih.gov]

  Introduction Laryngomalacia is the most common congenital laryngeal anomaly and is the most frequent congenital cause of stridor in infants. [pedsinreview.aappublications.org]

  When RA affects the cricoarytenoid joint, this may lead to acute stridor or dyspnoea, and potentially life-threatening complications. We report a case of RA patient with acute laryngeal stridor [ 1 ]. [omicsonline.org]

  Inspiratory stridor and increased work of breathing are the hallmarks. [lifeinthefastlane.com]

• Dyspnea

  D L CO% predicted was also the strongest correlate of dyspnea/̇VO 2 slope (r = -0.352, p = 0.005). [ncbi.nlm.nih.gov]

  For example, when exertional dyspnea occurs, the airway diameter is likely to be reduced to about 8mm. Dyspnea at rest develops when the airway diameter reaches 5mm. [pulmonologyadvisor.com]

• Decreased Breath Sounds

  Foreign body aspiration differs in the presence of unilateral wheezing and decreased breath sounds. [emedicine.medscape.com]

  Doctors look for signs that include: alterations in your normal breathing pattern, whether rapid or shallow breathing decreased breath sounds in your lungs high-pitched breath sounds in the upper airway or mouth no breathing bluish skin color unconsciousness [healthline.com]

  The chest examination revealed bilaterally decreasing breath sounds, with transmitted sounds from the upper airway, wheezing and whispery sounds. [casesjournal.biomedcentral.com]

• Dyspnea at Rest

   Dyspnea at rest develops when the airway diameter reaches 5 mm, coinciding with the onset of stridor.  Sound recordings from the neck and chest have shown that the sound signals from the asthmatic wheeze and stridor are of similar frequency. [slideshare.net]

  For example, when exertional dyspnea occurs, the airway diameter is likely to be reduced to about 8 mm. Dyspnea at rest develops when the airway diameter reaches 5 mm. [clinicaladvisor.com]

  For example, when exertional dyspnea occurs, the airway diameter is likely to be reduced to about 8mm. Dyspnea at rest develops when the airway diameter reaches 5mm. [pulmonologyadvisor.com]

• Hypertension

  […] sleep apnea and intracranial hypertension. [ncbi.nlm.nih.gov]

  In addition, some medications cause swelling of the turbinates, including some anti-hypertensive agents, anti-depressants, oral contraceptives and even chronic use of decongestant sprays or nose drops. [nasen-zentrum.de]

  Arterial desaturation is a late manifestation; better indicators of severity include stridor, poor air movement, accessory muscle use, abnormal mentation or agitation, tachycardia, hypertension, and pulsus paradoxus. [accessmedicine.mhmedical.com]

• Heart Disease

  Takotsubo cardiomyopathy can mimic true ischaemic heart disease and the diagnosis requires a high index of suspicion in patients managed with nebulised adrenaline. [ncbi.nlm.nih.gov]

  A fetal echocardiogram will detect structural heart disease. A prenatal karyotype (the study of the chromosomes of cells) will confirm chromosomal abnormalities. [cincinnatichildrens.org]

• Heart Failure

  The fetus should be followed closely for early signs of hydrops (in utero heart failure). [cincinnatichildrens.org]

  Overdistention of the lungs can put pressure on the heart and effect the heart’s ability to function. If the heart cannot beat effectively hydrops (congestive heart failure) can occur. The cause of CHAOS is currently unknown. [fetus.ucsf.edu]

  This can put pressure on the heart and affect its function. If the heart can't beat effectively, congestive heart failure can occur. The cause of CHAOS is currently unknown. It is a very rare condition and is not thought to recur in families. [ucsfbenioffchildrens.org]

  Signs of right-sided heart failure, such as hepatic congestion and ankle edema, may appear. In addition, airway narrowing often coincides with the appearance of stridor. Beware: there are other diseases that can mimic an upper airway obstruction. [pulmonologyadvisor.com]

• Neck Pain

  This client was completely unaware of any obstruction in the airway yet suffered from many clinical symptoms including lack of sleep, grinding of their teeth, pain and spasms in the neck and shoulders. [massagetoday.com]

• Facial Edema

  Two patients with inspiratory stridor, anterior neck swelling, and facial edema progressed to respiratory distress and their hematomas were removed by surgery, during which, sustained superficial venous bleeding was confirmed. [ncbi.nlm.nih.gov]

• Confusion

  The condition can also be described as Choking and is typically observed in very young children The manifestations of Upper Airway Obstruction (UAO) include difficulty breathing, choking, agitation, confusion, and unconsciousness. [dovemed.com]

  It is important not to confuse this emergency with other conditions that may cause sudden respiratory distress, cyanosis or loss of consciousness. [gponline.com]

• Dizziness

  Therefore, in addition to respiratory symptoms, the presence of hives, itching, flushing, nausea, vomiting, diarrhea, abdominal pain, dizziness, shock, and headache should suggest anaphylaxis; when these symptoms (especially skin involvement) are absent [pulmonologyadvisor.com]

Depending on the results of your examination, you may require further workup in the form of scans, blood work or biopsies. Many different treatment options are available depending upon your diagnosis. [hopkinsmedicine.org]

Septic workup should likely include a chest X-ray, labs including lactate, VBG, and blood cultures. Get your “double set up” airway equipment to the bedside. [emergencymedicinecases.com]

Hypoxemia upon exercise has been reported in a series of seven patients secondary to alveolar hypoventilation. 6 Exertional hypoxemia in a patient with a normal diffusion capacity is reflective of alveolar hypoventilation that calls for further workup [rtmagazine.com]

• Investigations add little in the initial workup • As viral croup is the commonest cause of UAO, attempts to identify other causes is also very important to confirm the diagnosis. 16. [slideshare.net]

Pathophysiology After foreign body aspiration occurs, the foreign body can settle into 3 anatomic sites, the larynx, trachea, or bronchus. Of aspirated foreign bodies, 80-90% become lodged in the bronchi. [emedicine.medscape.com]

The safety of high pressure source ventilation (jet ventilation) is dependent upon upper airway patency to facilitate adequate passive expiration and prevent increasing intrathoracic pressure and its associated deleterious sequelae. [ncbi.nlm.nih.gov]

Prevention is highly emphasized here because once an airway becomes obstructed, we have a very short time to deal with this life threatening emergency. We work all the time with techniques and vigilence to prevent this. [erikrichmond.com]

How can it be prevented? How can I tell if my child is choking? How is it treated? What is airway obstruction? Airway obstruction is when something prevents air from reaching the lungs and the brain. [virtualpediatrichospital.org]
