Overview
The majority of patients with [disease name] are asymptomatic.
OR
The hallmark of [disease name] is [finding]. A positive history of [finding 1] and [finding 2] is suggestive of [disease name]. The most common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3]. Common symptoms of [disease] include [symptom 1], [symptom 2], and [symptom 3]. Less common symptoms of [disease name] include [symptom 1], [symptom 2], and [symptom 3].

History
- Timing of onset of cyanosis
- congenital: Onset of cyanosis in early neonatal period is suggestive of congenital etiology (eg, congenital heat diseases with right to left shunts, congenital airway anomalies).
- Acquired: Recent onset is suggestive of acquired etiology (eg, pulmonary embolus, pneumonia, asthma, cardiac failure).
- Exposures:
- History of smoke inhalation and asphyxiating gases.
- History of exposure to low oxygen environments (eg, carbon monoxide poisoning, hydrogen cyanide poisoning).
- History of trauma:
- Motor vehicle collisions
- External chest compression
- History of trauma to upper airway and chest wall (eg, Flail chest, upper airway fractures, pneumothorax, hemothorax).
- History of prior lung disease:
- Exacerbation of pre-existing lung diseases (eg, Asthma, COPD, interstitial lung diseases) can cause respiratory distress and lead to cyanosis.
- History of congenital heart diseases:
- Congenital heart disease present with profound central cyanosis in the early neonatal period.
- Left-side obstructive lesions (eg, hypoplastic left heart syndrome, aortic stenosis, coarctation of the aorta)
- Right-sided obstructive lesions (eg, Tetralogy of Fallot, pulmonary atresia with intact ventricular septum, critical pulmonary stenosis, tricuspid atresia, Ebstein's anomaly)
- Transposition of the great arteries
- Truncus arteriosus
- Total anomalous pulmonary venous connection
- Congenital heart disease present with profound central cyanosis in the early neonatal period.
- History of neurologic disease:
- Any neurologic condition that results in respiratory distress can cause cyanosis (eg, seizures, central nervous system lesions, cyanotic breath holding spells and neuromuscular disorders).
- History of medications:
- Drugs causing methemoglobinemia (eg, Dapsone, nitrates, nitroglycerin, local anesthetics, chloroquine, anilines and aniline dyes.)
- Drugs causing sulfhemoglobinemia (eg, sulfonamides, metoclopramide)
- Amiodarone
- Beta blockers
- Silver
- History of fever
- Fever may be present in infectious causes of cyanosis secondary to upper airway obstruction (eg, croup), lower airway disease (eg, pneumonia, empyema), and septic shock.
- Current or frequent exposure to cold
