I often wish there was one place I could refer parents to so they could see what various coughs sound like, so I decided to put a list together. The internet is ripe with videos now, but I have spent many hours watching videos that weren't very helpful in order to find these. I'm sure I missed some of the best ones, so if you have one that you really like, please post in the comments below.
My next blog will be on how to treat cough and colds.
Regardless of how the cough sounds, if you are worried about your child's breathing or the sound of the cough, bring your child in to be seen.
Disclaimer: I have no ties to any of the videos below and am not responsible for any of the opinions or errors within them. Some are professionally done and others are videos parents uploaded. Some have advertisements which I do not necessarily endorse.
The initial seconds of this baby with croup stridor video show the typical croupy cough. At about 0:55 it shows the stridor that many kids with croup have. Stridor is a whistling sound as the baby breathes in (often confused with wheezing, which happens when you breathe out). It is common in croup and is caused by the swelling near the voice box. (Older kids and adults who get the same viruses that cause croup in younger kids often get laryngitis from the swelling near the voice box in a larger neck.)
This ER physician of TheEDExitVideo spends the first couple of minutes discussing what causes croup. At 2:27 sounds of stridor in an otherwise happy looking baby are shown. At 3:44 is a picture showing intercostal retractions (also seen with wheezing or other types of respiratory distress).
Dry cough can be from an irritation in the throat, asthma, acid reflux, or any common cold. It can also come from a habit cough (often seen after an illness and goes away with sleep only to return when awake).
The cough with pneumonia can sound like a wet cough or dry cough, so no specific videos are for this cause of cough. The clues to pneumonia include a fever with cough, difficulty breathing between coughs, shallow breathing, shortness of breath with brief exertion, pain in the chest, rapid breathing, or vomiting after cough. Pneumonia can be caused from viruses and bacteria and can range in severity. Walking pneumonia generally means that the person is not sick enough to require hospitalization. Some pneumonias lead to severe difficulty breathing and require oxygen support.
Wet cough can be from pneumonia or bronchitis, but also from postnasal drip with a common cold or allergies.
When kids "cough stuff up" it is usually the postnasal drip being coughed up, not mucus from the lungs coming up. The same is true if they "cough up blood". This blood is usually from a bloody nose draining into the throat, not from lung tissue. (Note: bloody mucus can be from more serious causes and if your child has no signs of blood in the nose or is otherwise ill, he should be properly assessed by a physician.)
WheezingWheezing is typical in asthma (and bronchiolitis). Many parents mistake the upper airway congestion sound that many kids make with postnasal drip as wheezing. Wheezing can sound like a whistle as a child breathes out. Ethan's wheezing shows a baby with noisy breathing without distress. This Wheezing - Lung Sounds Collection video has the sounds one would hear with a stethoscope, but if you put your ear against your child's back (without a shirt) you might be able to hear them. If you don't hear wheezing, but your child is struggling to breathe, it does not mean there is no wheezing! Treat like you would if you hear the wheeze.
AsthmaAsthma Attack in a child starts with information on asthma, then at 1:50 video of what retractions look like.
Asthma attack shows the typical short breathing in phase with long exhale seen with an asthma attack. Also you can see the airway pulling in at the neck (retractions).
Bronchiolitis, often simply called RSV, but caused by many virusesBronchiolitis Cough, 3.5 months old shows a baby with a wet sounding cough, typical of bronchiolitis.
Bronchiolitis is a video from the ER physician Dr Oller. He reviews causes of bronchiolitis, how it's spread, and how it affects the body. At 1:40 he discusses the natural progression of the simple cold into bronchiolitis. At 3:04 there is a picture of how we collect a nasal swab to help with diagnose of any viral illness.
Sick with Bronchilitis shows an infant with suprasternal retractions (sucking in at the base of the neck) and the typical cough associated with bronchiolitis. The man erroneously says "croupy", see below for croup.
RSV and Infant Treatment shows the best treatment for babies with RSV (or any bronchitis): suctioning. Some babies need this deep suctioning in the doctor's office or hospital. Others can get by with nasal aspirating at home. (Note, the next blog will be about treatments, but I have to say here that the bulb syringe is fairly useless for this.)
Pertussis - Whooping Cough: A Family's Story is an informational video on pertussis with the classic whooping cough in a child and pictures of a newborn with pertussis.
Silence the Sounds of Pertussis - Whooping Cough is a commercial for vaccinating, but it starts with the typical whooping cough sound.
Pertussis (whooping cough) shows a young infant with a cough from pertussis. Young infants do not always whoop, they stop breathing.
8 Year Old With Pertussis (Whooping Cough) shows a typical cough for an older child. Her positioning in front of the toilet shows that these kids often vomit from the force of the cough. The 2nd video from this same girl shows how normal and healthy kids can appear between episodes.
