Pneumonia

Symptoms

• Cough: Often brings up mucus that may be yellow, green, or rust-colored.
• Fever and chills: A raised temperature, sometimes with shaking chills or sweating.
• Shortness of breath: Feeling breathless during normal activity or, in severe cases, at rest.
• Chest pain: A sharp or stabbing pain that gets worse when you breathe deeply or cough.
• Fatigue: Marked tiredness or weakness that is out of proportion to a common cold.
• Rapid or shallow breathing: Breathing faster than usual to take in enough oxygen.
• Confusion: New confusion or reduced alertness, especially in adults over 65.
• Loss of appetite: Not wanting to eat or drink, which can lead to dehydration.

When it's an emergency

Call 911 immediately for severe breathing trouble, blue lips or new confusion. Seek prompt emergency evaluation if you have trouble breathing or are short of breath at rest, chest pain, a bluish tint to the lips or fingernails, or new confusion. These can be signs of dangerously low oxygen or a severe, spreading infection.

Also seek emergency care for a high fever that will not come down, coughing up blood or rust-colored mucus, a rapid heartbeat, or breathing that is fast and labored. Pneumonia can progress quickly, especially in adults over 65, infants, and people with heart disease, diabetes, lung conditions, or a weakened immune system.

Untreated or worsening pneumonia can lead to serious complications such as low blood oxygen, sepsis, or respiratory failure. When breathing is affected, it is always safer to be evaluated promptly than to wait it out at home. Bellaire ER evaluates and stabilizes pneumonia on-site 24/7 with chest X-ray, labs, and oxygen, and arranges hospital transfer when admission is required.

When it's not an emergency

Mild pneumonia in an otherwise healthy adult can sometimes be managed outside the ER. If you have a cough, a low-grade fever, and are breathing comfortably without chest pain or confusion, a telemedicine visit or your primary care physician can evaluate you and, if bacterial pneumonia is likely, prescribe oral antibiotics.

Bellaire ER's virtual urgent care is also reasonable for a routine follow-up or to review symptoms that are slowly improving. However, if you have trouble breathing, a high or persistent fever, chest pain, confusion, or belong to a higher-risk group, choose the ER instead of waiting for an appointment.

What else could be causing this

Bacterial pneumonia

Most often Streptococcus pneumoniae. Tends to come on quickly with a high fever, shaking chills, and a cough bringing up colored phlegm. This is the type antibiotics treat directly.

Viral pneumonia

Influenza, RSV, COVID-19 and others. Usually a slower build with body aches, dry cough and breathlessness. Antibiotics do not help a virus, though a bacterial infection can follow one.

Aspiration pneumonia

Food, drink or stomach contents entering the lungs. More common after a stroke, with swallowing difficulty, reflux, or heavy alcohol use.

Atypical or walking pneumonia

Mycoplasma and similar organisms. Milder and more drawn out, a persistent dry cough and tiredness in someone still up and about.

Fungal pneumonia

Uncommon, and mostly in people whose immune system is suppressed.

What it is often mistaken for

Bronchitis, asthma, heart failure and a clot in the lung all cause cough and breathlessness. Telling them apart is what the chest imaging is for.

What happens when you arrive

At Bellaire ER a board-certified emergency physician checks your oxygen level, listens to your lungs, and reviews your symptoms and history. Because timing matters with pneumonia, evaluation begins right away.

We confirm the diagnosis with an on-site chest X-ray, and we can add lab work, CT, or ultrasound as needed. This lets us see how much of the lung is involved and check for complications without sending you elsewhere.

Treatment is tailored to your condition and may include antibiotics, supplemental oxygen, IV fluids, and medication to bring down fever and ease breathing. We diagnose and treat in a single visit, and most patients do not need a hospital transfer. Before you leave, your physician explains your results and gives you a clear follow-up plan.

Tests we can run on site

Chest X-ray

The test that confirms it. Pneumonia shows as consolidation, a dense area where air sacs have filled with fluid. It also shows how much of the lung is involved and whether fluid has collected around it.

Pulse oximetry

Blood oxygen, measured painlessly on a fingertip. A low reading is one of the clearest signals that pneumonia needs hospital care rather than treatment at home.

Blood count and inflammatory markers

Helps separate a bacterial infection from a viral one and shows how hard the body is working against it.

Respiratory viral panel

Identifies influenza, RSV or COVID-19, which changes treatment and whether an antiviral is useful.

CT scan

Used when the X-ray is unclear, when there is fluid around the lung, or when a clot needs excluding.

Treated here, or transferred

Most pneumonia in otherwise well adults is treated as an outpatient. Antibiotics for a bacterial cause, fluids, fever control, with the first doses given here and a prescription written for you to fill, plus clear instructions on what should improve and by when.

Some pneumonia needs a hospital. Low blood oxygen, confusion, low blood pressure, a large area of lung involved, or significant underlying heart or lung disease all point that way. Bellaire ER confirms the diagnosis on site with X-ray and blood work, starts oxygen and antibiotics immediately, and arranges transfer where admission is needed. Treatment begins here rather than waiting for a bed.

Viral pneumonia is treated supportively, with an antiviral where influenza is confirmed early enough to help.

Children

Pneumonia is common in children and often follows a cold. Watch the breathing rather than the temperature: fast breathing, the skin pulling in between or under the ribs, nostrils flaring, or grunting are the signs that matter, and they matter more than how high the fever is.

Call 911 immediately for severe breathing trouble, blue lips or a child who is floppy or difficult to wake. Seek prompt emergency evaluation for difficulty breathing, blue lips, unusual drowsiness or floppiness, refusing to drink, or fewer wet diapers. Infants under three months with any fever need to be seen the same day.

Bellaire ER treats children and adults, with the same on-site X-ray and laboratory.

After you leave

Pneumonia should start improving within two to three days of starting treatment. Fever settles first; the cough and the tiredness take considerably longer, often several weeks, and that is normal.

Call 911 immediately for severe breathing trouble, blue lips or confusion with difficulty waking. Seek prompt emergency evaluation if you become more breathless, your fever returns after settling, you become confused or unusually drowsy, your lips or fingertips look blue, or you cough up blood. Those mean it is not responding.

Finish the whole antibiotic course even once you feel better. Stopping early is the usual reason pneumonia comes back worse.

A follow-up chest X-ray is often recommended six to eight weeks later to confirm the lung has cleared, particularly for smokers and anyone over 50.

Lowering your risk

You can lower your risk of pneumonia with vaccination. Pneumococcal vaccines, the yearly flu shot, and staying current on COVID-19 vaccines all help prevent infections that can lead to pneumonia, particularly for adults over 65 and people with chronic health conditions.

Good habits also reduce risk: wash your hands regularly, do not smoke, and manage conditions like asthma, COPD, and diabetes. Treating a cold or flu early and resting can keep a minor illness from progressing to pneumonia.
