What is bronchiolitis?

Lung infection. Bronchiolitis is an infection of the smallest breathing tubes in the lungs (bronchioles). The small airways become inflamed, swollen and filled with mucus. This can lead to breathing difficulty. It is caused by viruses such as RSV and influenza. It is more common in children under age 2 and peaks at 3-6 months of age.
Viral lung infection. Bronchiolitis is a viral lung infection that causes damage and mucous in the smaller airways (air passages) in the lungs. Bronchiolitis is usually caused by the RSV virus, and occurs in babies and toddlers. After age 2 years, children have better immunity and can usually block the RSV virus from damaging the lungs. So, older children and adults just have cold symptoms when they catch rsv.
A viral infection. Bronchiolitis usually affects children under the age of 2, and is even more common in the first 6 months of life. It is a common, and sometimes severe illness. Viruses that can cause bronchiolitis include: rsv, flu and adenovirus. Bronchiolitis essentially is swelling and snot in the smallest air passages in the lungs.
Small airway infect. If you think of the lungs as a tree upside down with limbs representing airways, the bronchioles are like the smaller branches and twigs where the leaves (air exchange blebs)attach. In broonchiolitis these air channels are often filled with excess mucous and may spasm with infectious swelling. The result is hampered oxygen exchange, wheezing and cough.

What is bronchiolitis?

Infant infection. Bronchiolitis is a condition of the lungs in infants. It is caused by a viral illness, RSV as an example, that causes inflammation (swelling) in the lung tissues. A baby often has a runny nose and cough, with a faster breathing rate. Time is usually the cure but some episodes can worsen, requiring medication and occasional hospitalization.
A viral respiratory. A viral respiratory infection in the lungs (not pneumonia) of an infant or young child. Treatment is supportive. Suction the mucus.
Lung viral infection. Bronchiolitis is an inflammation of the small airways (bronchioles), usually caused by a viral infection which causes disease in infants mainly and is characterised by: ◦low grade fever up to 38.5°C ◦nasal discharge ◦cough •75% of cases are caused by respiratory syncytial virus (RSV) Because this is a viral infection, patient does not require antibiotics but may require oxygen therapy if severe.

What causes bronchiolitis?

Virus (usually RSV) Bronchiolitis is caused by a viral infection, usually RSV (respiratory syncytial virus.) it adults and older kids, it usually just causes a "common cold." in infants, though, it can also cause wheezing and breathing problems which can sometimes be severe.
Virus- could be RSV. Viral colds are the most common cause of bronchilitis in babies. Many viruses can be the culprit. Rsv (respiratory syncitial virus) is a very common cause, especially in premature infants. Children under two years of age are most at risk and the younger the child, potentially the more severe the symptoms could be.
Lots of things. Could be rsv, hmpv, adenovirus, flu, paraflu, rhinovirus etc. Watch http://www. Youtube. Com/watch? V=5teb03heixw&feature=related to learn more.

What is bronchiolitis obliterans with organizing pneumonia?

Inflammation. The cause of bronchiolitis obliterans with organizing pneumonia is unknown, but may be caused by a viral infection which sets off an inflammatory reaction in the small airways and airspaces. It causes cough and shortness of breath. It is diagnosed with lung biopsy. Treatment is generally corticosteroids like Prednisone which may be needed for months. It has been associated with autoimmune diseases.

Hi doctors, was just wondering what is "bronchiolitis obliterans with organizing pneumonia"?

Chronic lung disease. Bo is a form of obstructive lung disease that leads to the "obliteration" of small airways due to fibrosis. It can be caused by inhalational injuries, autoimmune diseases, lung infections, or following-transplant. In children, it can be seen after a severe lung infection, usually with adenovirus.

What does having bronchiolitis mean?

Lower resp Infection. Bronchiolitis is an infection of the small breathing tubes (bronchioles) of the lungs. It's usually caused by a virus. The infection can cause swelling in those small airways, extra fluid production, and therefore making it hard for your baby to breath sometimes. It usually start with some mild cough and congestion that progressively worsens and can lead to fast breathing.
Viral infection. Bronchiolitis is a viral infection that younger children (usually under 2 years old) get. In infants and children with bronchiolitis, the virus affects the lungs. So in addition to congestion and cough, you also get wheezing or labored breathing. Bronchiolitis is sometimes treated with inhalers that are also used for asthma.
Inflammed airways. Bronchiolitis refers to inflammation of the small airway 'tubes' (bronchioles) leading to the air sacs (alveoli) in the lungs, typically occurring in young children. The disease is typically viral and self-limited. Treatment is generally supportive, but therapies such as bronchodilators (ie. Albuterol), may be attempted to see if a patient benefits from this therapy.

What bronchiolitis symptoms do babies and toddlers have?

Wheeze, cough. Bronchiolitis usually caused by RSV generally causes wheezing and coughing along with difficult breathing. Symptoms can vary from mild to severe requiring hospitalization at times.
Wheezing! Babies with bronchiolitis, or a viral infection of the small airways in the lungs, have cough, funny nose, fever and wheezing. They may have decreased appetite and have trouble sleeping. If your baby is breathing fast, wheezing, or has a persistent cough, see your pediatrician.
Nasal mucous, cough. Babies and toddlers with RSV virus infection have lots of nasal mucous, so they have some trouble breathing through the nose. The mucous also forms in the lungs, so they cough and wheeze. They breathe fast, making it hard for them to eat or swallow. They work harder to breathe, sometimes sucking in the skin between ribs, and get very tired. Hospitalization may be needed for symptoms like these.
Common cold. Early symptoms include runny nose, stuffiness, mild cough and sneezing. A few days later, more serious symptoms develop such as fever, trouble breathing, wheezing, irritability and flaring of the nostrils.
Crackles - fine. A symptom not mentioned above, but quite commonly seen with bronchiolitis is fine crackles on auscultation of the chest.

What is RSV bronchiolitis, and what is the age of a child when the child is no longer susceptible to it?

Always can get it. The issue is the younger the baby, the more severe the symptoms can be, once you are an older toddler or even an adult, if you catch it you just get "cold" symptoms.
Varies by case. Most kids over 16-17 lb are at least not sick enough with RSV to require hospitalization. Most of this is due to growth and the problems little lungs have clearing the extra mucous made during the illness. This is not so bad when lungs are bigger. Kids with asthmatic tendencies can have trouble with RSV well into their 3 rd year. Most do not even though most get it most seasons.

What bronchiolitis symptoms should I watch out for that warrant a hospital visit?

Trouble breath & eat. Trouble breathing-- gasping, pulling in ribs, breathing with belly muscles, or breathing with prominent caving in of ribs, or trouble taking a breast or bottle, or lethargy should all warrant contacting the pediatrician and visiting the ER in bronchiolitis.
Rapid breathing. Bronchiolitis is an infection of the lungs caused by several viruses, including RSV and the flu. Most cases start with mild symptoms of runny nose and cough. Symptoms to watch out for that may need a visit to the hospital or your doctor include rapid breathing, retractions (the pulling-in of belly and chest muscles in an effort to breath), and paleness or cyanosis, a bluish tinge around the lips.
Respiratory distress. Working hard to breathe, breathing more than 60 times per minute, and having difficulty breathing so that she cannot comfortably feed are all signs that she should be seen as soon as possible and may need hospitalization. If she develops wheezing or retractions (sucking in under neck or between ribs when breathing in) she should also be seen as soon as possible.
Blue lips. Or tugging in between the ribs or gasping for air all warrant an emergent visit.
Apnea; cyanosis. Apnea refers to a period where someone stops breathing entirely for 20 seconds or more. Cyanosis refers to a bluish discoloration to the skin that happens when someone is hypoxic. Both are signs of severe respiratory compromise that can occur with bronchiolitis, and need to be emergently evaluated.
Baby looks too sick. If a baby just looks too sick to a parent, then it's time to go to the hospital er, by ambulance if needed. If a baby with bronchiolitis was seen by a doctor and then cleared to be observed at home, the parents can look for any signs of worsening. Examples: baby no longer a nice pink color, baby more tired as hours pass, baby has trouble eating/swallowing, baby breathing >60 times a minute..
Respiratory Distress. Respiratory distress (shortness of breath) can be a sign that your babies bronchiolitis has gotten more serious. Typically this means that they are breathing faster (tachypneic), breathing harder and sucking in the muscles between their ribs and under their ribs (retracting), making a noise with breathing out (wheezing/grunting), and flaring their nostrils. Dehydration would be another symptom.
Difficulty breathing. Bronchiolitis tends to be more severe in children under 1 year of age, babies born early, or children with underlying medical problems. One worrisome sign is retractions, when a baby is breathing so hard that s/he is pulling at her/his skin and you can see the ribs as s/he breathes. Any hard, fast breathing, flaring of the nostrils, or high fever over 3 days should also be checked by your doctor.

What are the tests for bronchiolitis?

Rsv test. There is a nose swab test for RSV (respiratory syncytial virus) and other similar viruses. However the doctor doesn't have to do any tests. They can make the diagnosis by the symptoms and by examining the baby.
