When your baby is wheezing, breathing fast, or struggling to feed, you need answers quickly. ER of Mesquite – Emergency Room is open 24/7 at 1080 E Cartwright Rd Ste 100, Mesquite, TX 75149, and our ER doctors evaluate infants, children, adults, and older adults with RSV. We offer RSV testing, oxygen level monitoring, and oxygen support. Walk in anytime, no appointment needed.
Call 911 first if: Your baby turns blue or gray, stops breathing for several seconds, or is limp and hard to wake. Do not drive; call 911 for immediate help.
RSV (respiratory syncytial virus) usually looks like a cold, and most children recover at home. But in babies, especially those under 6 months, premature infants, and babies with heart or lung conditions, it can inflame the small airways and make breathing hard.
Bring your baby to the ER if breathing is fast or labored, if your baby is wheezing, if feeding drops sharply, or if you see signs of dehydration. A high fever is another reason to be seen; see our high fever treatment page. Trust your instincts: if your baby looks worse than a cold, come in.

RSV breathing problems in infants can progress quickly, so know what to look for. Come to the ER right away if you notice any of these signs.
Our team checks your child’s oxygen level and breathing effort first. For older children with a history of wheezing, our asthma emergency care page may also help, and our breathing problems treatment page covers labored breathing at any age.
Babies with RSV often struggle to feed because a stuffy nose and fast breathing make sucking hard. That can lead to dehydration quickly. Warning signs include fewer wet diapers, no wet diaper in 8 hours, a dry mouth, crying without tears, a sunken soft spot on the head, and unusual sleepiness. If your baby shows these signs, our team can treat dehydration with IV fluids and monitor how your baby responds.
RSV is not only a childhood illness. In healthy adults it often feels like a cold with a runny nose, cough, sore throat, and low fever. In adults 60 and older, and in people with asthma, COPD, heart disease, or weakened immunity, it can cause pneumonia or worsen an existing condition.
Come to the ER for shortness of breath, wheezing, chest tightness, a cough that keeps getting worse, bluish lips, or confusion. Because RSV, flu, and COVID-19 look similar, see our emergency flu treatment page as well.
At ER of Mesquite – Emergency Room, RSV care starts with an emergency assessment: vital signs, oxygen level, and a check of breathing effort. A quick nasal swab can test for RSV, and we can check for flu and COVID-19 at the same time. A chest X-ray may be used to look at the lungs, and on-site lab testing can help when dehydration or infection is a concern.
There is no cure for RSV, so treatment supports your child while the body fights the virus. That can include clearing nasal congestion, oxygen support when levels are low, fluids for dehydration, and close monitoring. Antibiotics do not treat RSV, but they may be considered if a bacterial infection develops.

As a freestanding emergency room, your visit follows a clear path. You arrive and are seen right away by our team. Our ER doctors complete an emergency assessment of breathing, oxygen, and hydration. Testing follows as needed.
We stabilize your child and start supportive treatment. If a baby needs hospital admission, ongoing oxygen support, or pediatric specialty care, we coordinate the transfer to an appropriate hospital and share records so care continues smoothly. Learn more on our No Wait ER page, or review our insurance coverage information before you come in.
We serve families and patients throughout Mesquite, Balch Springs, Sunnyvale, Forney, Garland, and Seagoville, 24 hours a day, 7 days a week.
Go to the ER if your baby breathes fast or with effort, wheezes, flares the nostrils, has pauses in breathing, will not feed, or has bluish lips. Call 911 if your baby turns blue or stops breathing.
There is no cure for RSV, so care is supportive. Our ER team checks oxygen levels, clears nasal congestion, gives oxygen if needed, treats dehydration with IV fluids, and coordinates transfer if hospital admission is needed.
Look for fast breathing, nostrils flaring, grunting, wheezing, and skin pulling in between or under the ribs. Pauses in breathing or a bluish color around the lips mean emergency care now.
Warning signs include fewer wet diapers, no wet diaper in 8 hours, a dry mouth, crying without tears, a sunken soft spot on the head, and unusual sleepiness. Babies who cannot feed need an ER evaluation.
Yes. RSV can cause pneumonia or worsen asthma, COPD and heart failure, especially in adults 60 and older. Shortness of breath, wheezing, chest tightness, or a fever with a worsening cough needs ER care.
The ER uses a quick nasal swab to test for RSV, and can check for flu and COVID-19 at the same time. Doctors also measure oxygen levels and may take a chest X-ray to look at the lungs.
