Choking, also known as foreign body airway obstruction (FBAO), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract.An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation.
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
If the foreign body does not cause a large degree of obstruction, patients may present with chronic cough, asymmetrical breath sounds on exam, or recurrent pneumonia of a specific lung lobe. [2] If the aspiration occurred weeks or even months ago, the object may lead to an obstructive pneumonia or even a lung abscess.
Another popular hiccup maneuver, drinking water upside down, may increase the risk of aspiration or choking. "Some water or gastric secretions can go into your lungs, which can predispose you for ...
Resonance: Loud and low pitched. Normal lung sound. [15] Dullness: Medium intensity and pitch. Experienced with fluid. [14] A dull, muffled sound may replace resonance in conditions like pneumonia or hemothorax. Hyper-resonance: Very loud, very low pitch, and longer in duration. Abnormal. [14] Hyper-resonance can result from asthma or emphysema
It is sometimes misinterpreted as the sound of the person choking to death or gargling. Notably, death rattle is a separate phenomenon from agonal respiration, ataxic respiration, and Kussmaul respiration. [4]
The lungs are normally protected against aspiration by a series of protective reflexes such as coughing and swallowing. Significant aspiration can only occur if the protective reflexes are absent or severely diminished (in neurological disease, coma, drug overdose, sedation or general anesthesia).
This squeezes air out of the baby’s lungs and may help dislodge the blockage, according to the British Red Cross. If a baby is choking, the British Red Cross recommends giving up to five back ...
