A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
A history of exposure to potential causes and evaluation of symptoms may help in revealing the cause the exacerbation, which helps in choosing the best treatment. A sputum culture can specify which strain is causing a bacterial AECB. [5] An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8]
It causes difficulty in breathing which ranges from mild to severe. Bronchospasms occur in asthma , chronic bronchitis and anaphylaxis . Bronchospasms are a possible side effect of some drugs: pilocarpine , beta blockers (used to treat hypertension), a paradoxical result of using LABA drugs (to treat COPD ), and other drugs.
Use of dexamethasone 4–8 mg IV q 8 - 12 h in cases where airway edema may be the cause of the stridor; note that some time (in the range of hours) may be needed for dexamethasone to work fully. Use of inhaled Heliox (70% helium, 30% oxygen); the effect is almost instantaneous. Helium, being a less dense gas than nitrogen, reduces turbulent ...
Asthma is a common condition and affects over 300 million people around the world. [3] Asthma causes recurring episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning. [4] Exercise-induced asthma is common in asthmatics, especially after participation in outdoor activities in cold weather.
A PCP will ask questions in regards to symptoms and breathing; they will also ask if fatigue or wheezing has been experienced when breathing in or out; and also test using a peak expiratory flow and an oxygen saturation. Status asthmaticus can be misdiagnosed when wheezing occurs from an acute cause other than asthma. Some of these alternative ...
Crackles are more common during the inspiratory than the expiratory phase of breathing, but they may be heard during the expiratory phase. Crackles are often described as fine, medium, and coarse. They can also be characterized as to their timing: fine crackles are usually late-inspiratory, whereas coarse crackles are early inspiratory.
Some children get tracheomalacia because of other health issues. Symptoms can be mild to severe. [citation needed] Symptoms inside the lung include noisy breathing that may get better when you change your baby's position or while he or she is asleep. Breathing problems that get worse during coughing, crying, feeding or colds.
