Pneumonia is a lung infection that causes air sacs in the lungs to fill with fluid or pus. Treatment for pneumonia depends on the type of pneumonia, the patient's age, their overall health, and the severity of the infection. Hospitalised patients with pneumonia are often treated with intravenous fluids (IV), antibiotics, and oxygen therapy. In more severe cases, a ventilator may be required.

What You'll Learn
Intravenous fluids and antibiotics
If pneumonia is severe, patients may need to be treated in a hospital where they can receive antibiotics and fluids intravenously (through an IV line inserted into their vein). This is necessary when the patient is too ill to take tablets or drink.
Intravenous fluids are administered to keep the patient hydrated, which is especially important if they have a fever. Fluids can also help to loosen the mucus in the lungs, making it easier and less painful for the patient to cough up.
Intravenous antibiotics are used to treat bacterial pneumonia. Antibiotics do not work against viruses, so it is important to determine the cause of the infection before administering treatment. If the pneumonia is viral, the patient may be prescribed antiviral medication instead. It is important to complete the full course of antibiotics, even if the patient starts to feel better, to ensure the infection does not return and to prevent antibiotic resistance in the future.
The treatment plan for pneumonia will depend on the cause of the infection (bacteria, virus, or fungi), as well as the patient's overall health, age, and risk factors. For example, patients over 65 or under 2 years of age are more likely to be hospitalized and are considered at higher risk for complications. Additionally, those with pre-existing lung conditions, weakened immune systems, or a history of alcohol misuse may also be at higher risk for complications and require more intensive treatment.

Oxygen therapy
As pneumonia progresses, the amount and type of oxygen required by the patient change; thus, careful clinical judgment is necessary. Healthcare professionals should be trained to recognize signs of oxygen toxicity, which can occur when patients receive too much oxygen. By understanding oxygen therapy protocols, practitioners can optimize patient outcomes and ensure safe and effective treatment.
Non-invasive ventilation, a specific type of oxygen therapy, has been found to reduce the risk of death in intensive care units (ICU) and the need for endotracheal intubation. It also shortens ICU stays and the length of intubation. However, the optimal ventilatory strategy for hypoxemic respiratory failure is still uncertain, and more research is needed to confirm the role of non-invasive mechanical ventilation delivered by a helmet and high-flow nasal cannula oxygen therapy.

Surgery to remove infected lung tissue
Pneumonia is a lung infection that causes air sacs in the lungs to fill up with fluid or pus. Treatment for pneumonia depends on the type of pneumonia, the severity of symptoms, age, and other health conditions. The goals of pneumonia treatment are to cure the infection and prevent complications.
In some cases of severe pneumonia, surgery may be required to remove seriously infected or damaged lung tissue. This procedure is called lung resection or pulmonary resection, and it involves the removal of part or all of the infected lung. Lung resection surgery can be performed in several ways, including:
- Wedge resection: A surgeon removes a wedge-shaped section of the infected lung tissue.
- Lobectomy: The entire lobe, or section, of the lung is removed.
- Pneumonectomy: The entire lung is removed.
Lung resection surgery can be performed using different techniques, including:
- Thoracotomy: This is a type of open surgery where a surgical cut is made to open the chest wall. The patient lies on their side, with their arm placed above their head. An incision is made between two ribs, passing from the front of the chest wall to the back, just under the armpit. The ribs are separated, and the lung is deflated to prevent air movement during the procedure.
- Video-assisted thoracoscopic surgery (VATS): This is a minimally invasive procedure where a thoracoscope (a thin, lighted tube with a small camera) is inserted into the chest through a small incision. The surgeon then performs the procedure using long, thin instruments.
- Robotic video-assisted thoracoscopic surgery (RVATS): Similar to VATS, this technique uses a robotic arm to perform the procedure.
After lung resection surgery, the patient is taken to a recovery room and can typically expect to spend about two to three days in the hospital. Most individuals will require chest tubes for 24 to 48 hours post-surgery to drain excess fluid and air. Deep breathing exercises are encouraged to help prevent pneumonia and infection, and to reinflate the operated lung.

Antiviral medication
Treatment for pneumonia depends on several factors, including the type of pneumonia, the severity of symptoms, age, and other underlying health conditions. The primary goals of treatment are to cure the infection and prevent complications. Hospital treatment for pneumonia may include intravenous fluids (IV), antibiotics, and oxygen therapy, with mechanical ventilation in severe cases.
If the pneumonia is bacterial, it can be treated with antibiotics. However, antibiotics are ineffective against viral pneumonia. In cases of viral pneumonia, doctors may prescribe antiviral medications. These antiviral drugs work to inhibit DNA synthesis and viral replication by competing with deoxyguanosine triphosphate for viral DNA polymerase.
There are a limited number of specific antiviral agents available. Acyclovir is effective for varicella and herpes simplex pneumonia. Ganciclovir and immunoglobulin are used for immunocompromised patients with CMV pneumonia. Remdesivir and nirmatrelvir/ritonavir are antiviral agents with full FDA approval for the prevention and treatment of COVID-19. Other antiviral agents include amantadine, rimantadine, zanamivir, oseltamivir, ribavirin, ganciclovir, and foscarnet, which can be used prophylactically or therapeutically.
Arbidol (ARB) is another antiviral molecule that exhibits broad-spectrum activity against RNA and DNA viruses. It has a dual pharmacological effect, acting on respiratory viruses and stimulating the immune system. Arbidol works by binding to viral hemagglutinin, blocking its binding to host cell receptors, and inhibiting viral entry and replication.
While these antiviral treatments have shown efficacy against specific viral infections, they also face challenges such as increased viral resistance, side effects, and limited effectiveness against certain virus types. To overcome these limitations, ongoing research focuses on new drug development, combination therapies, personalized medicine, and preventive measures. This includes the use of AI-driven drug design platforms, network pharmacology, and CRISPR-Cas9 gene editing technology to develop novel antiviral strategies and improve treatment outcomes.

Bronchoscopy
Treatment for pneumonia depends on the type of pneumonia, the patient's overall health, age, and how sick they are feeling. Bacterial pneumonia can be treated with antibiotics, while antiviral medication may be prescribed for viral pneumonia. In severe cases, hospital treatment may include antibiotics and fluids through an intravenous (IV) line, oxygen therapy, and possibly a ventilator. In some cases, surgery may be required to remove severely infected or damaged parts of the lung.
One such procedure that may be used in the treatment of pneumonia is bronchoscopy. This procedure involves inserting a bronchoscope—a thin, lighted tube—down the patient's throat and into the airways. Bronchoscopy can be used to diagnose and treat pneumonia and other lung infections, such as tuberculosis (TB) and fungal or parasitic infections. During the procedure, which typically lasts between 15 minutes to an hour, the patient is awake, but sedated, and their nose and throat are numbed to prevent gagging.
A flexible bronchoscope is more commonly used than a rigid one as it can access smaller areas of the lung tissue and has a lower risk of damaging the tissue. Through the bronchoscope, healthcare providers can examine the lungs, take tissue samples or mucus for testing, and perform additional procedures such as giving medicine or stopping bleeding. Before the procedure, patients may be asked to not eat or drink, and to stop taking certain medications.
Bronchoalveolar lavage (BAL) is a technique used in conjunction with bronchoscopy, where fluid is put into the lungs and then removed to diagnose lung disorders. This technique has been used in the context of pneumonia, particularly in patients with HIV or at risk for AIDS.

Frequently asked questions
If you are too ill to drink and take tablets, you may need to be admitted to the hospital for pneumonia. You may also need to be hospitalized if you are considered high-risk for complications, such as being older than 65 or younger than two, or having a weakened immune system.
At the hospital, you will receive fluids and antibiotics intravenously (through an IV). You may also receive oxygen therapy through a mask or nasal tube to maintain your blood oxygen levels. In severe cases, you may be put on a ventilator, a machine that pumps oxygen into your lungs.
Once you have started to recover, your doctor may recommend respiratory therapy. A trained therapist will teach you breathing exercises and help you maximize your recovery. If your pneumonia is caused by an object you’ve breathed in, you may have a bronchoscopy to look into your airways and lungs. The object may need to be removed.
