These abnormalities may be present in the neonatal period but are typically not detected until at least 6 months of age. [ncbi.nlm.nih.gov]

• 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]

  In the unconscious patient, hypopharyngeal obstruction by the base of the relaxed tongue occurs always when the neck is flexed and almost always when the head is in the mid-position. [jamanetwork.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]

  Attempts at coughing are silent. Patient may be unconscious. Adult choking sequence This is for adults and children over the age of one year. 1. [gponline.com]

• 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]

  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]

• 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]

• Tachypnea

  He was restless and agitated, in the "chest-knee'" position, with dyspnea, tachypnea and audible inspiratory stridor in the head up position. Cyanosis was present on the fingernails and lips. [casesjournal.biomedcentral.com]

  Clinical manifestations • Barking cough • Respiratory distress • Tachypnea • Inspiratory stridor • Hoarseness • Elevated temperature • Rapid pulse • Irritability • Dysphagia • In severe cases, manifestations may progress to shock, cyanosis, impaired consciousness [slideshare.net]

• Papilledema

  Intracranial hypertension was identified by the presence of papilledema on funduscopy, supplemented by optical coherence tomography and/or intracranial pressure monitoring. [ncbi.nlm.nih.gov]

• Akinesia

  Coronary angiography demonstrated no coronary artery disease, but left ventricular angiography showed marked apical ballooning and apical wall akinesia consistent with a diagnosis of takotsubo cardiomyopathy. [ncbi.nlm.nih.gov]

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]

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]

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]

• 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]

• T Wave Inversion

  A 12-lead electrocardiogram showed widespread T-wave inversion and QT prolongation suggestive of an acute coronary syndrome. [ncbi.nlm.nih.gov]

AP2, prior to FP treatment, was enriched with Streptococcus pneumoniae. [ncbi.nlm.nih.gov]

Laryngeal atresia is an extremely rare fetal anomaly with dismal prognosis. It is important to differentiate the condition from other lesions with a more favorable prognosis, such as congenital adenomatoid malformation of the lung. [ncbi.nlm.nih.gov]

The purpose of this retrospective review of a prospective database was to investigate etiologic factors related to the development of AAO due to postoperative hematoma after ACF and formulate appropriate prevention and treatment guidelines. [ncbi.nlm.nih.gov]

[…] genitalia, urinary tract anomalies, cryptophthalmos, and syndactyly. [6] The literature is scant, but a 2016 study by Tessier et al suggested that approximately 40% of neonates diagnosed with Fraser syndrome had evidence of CHAOS before birth. [7] The pathophysiology [emedicine.medscape.com]

Patient with large tracheal tumor Pathophysiology of variable intrathoracic obstruction: During expiration, the expiratory muscles increase intra-thoracic and intra-airway pressures. [pulmonologyadvisor.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]
