Does bronchiolitis cause low oxygen saturation?

It happends. Bronchiolitis causes a build up of secretions in the tiny airways and blocks transfer of oxygen into the tissues. It can and does cause a drop in blood oxygen in many cases.

My daughter has bronchiolitis and her oxygen saturation today fell to 92. After receiving several meds via nebulizer and her vein. Cause?

Bronchiolitis. Bronchiolitis is caused by viruses. The most common virus causing severe disease is the RSV or respiratory syncyitial virus. Sounds like your daughter was admitted to the hospital and being taken care of. One advice: the pulse ox varies all the time and perhaps her reading of 92 was only transient. Please be patient with her recovery as RSV always takes time to run its course in a lot of cases. Read more...
Mismatch. between areas in the lungs where the oxygen can get through constricted airways and those parts of the lung tissue where the most of the blood is circulating creates the drop in percentage of oxygenated hemoglobin (saturation). 92% is worrying, but if it does not drop any further, is not life-threatening in a 15 months old, as long as there is prompt access to care and adequate monitoring.

How much does a low oxygen saturation level affect judgment?

Oxygen. A low oxygen saturation definitely affects judgment. Your brain is one of the organs that is heavily dependent on proper oxygenation. If you decrease the oxygen saturation, judgment may be impaired. Read more...
Depends how low. Down to about 80% there isn't much effect at all at least for short periods of time. Longer periods weeks to months can have cognitive effects. Below 80% saturation there can be clear effects on judgment even for brief periods. The lower the saturation the bigger the effect. Read more...

What common medical conditions are associated with low oxygen saturation levels?

Lung & Heart Disease. Hypoxia (low oxygen saturations) are usually caused by lung disease (chronic obstructive pulmonary disease, asbestosis, pulmonary fibrosis, etc). Many heart conditions (especially congenital defects in the new born) may result in low oxygen saturation levels. Beware of false lows with pulse oximetry readingson cold hands, peripheral vascular disease or really callussed finger tips. Read more...
