Pneumonia is a serious lung infection that requires immediate medical attention. Treatment for pneumonia depends on the type of pneumonia, the patient's age, how sick they are, and other health conditions. If a patient is treated in a hospital, they may be given intravenous fluids, antibiotics, and oxygen therapy. Hospital-acquired pneumonia is often more dangerous and resistant to treatment than pneumonia acquired outside of the hospital. It is usually treated with strong antibiotics and, in some cases, a mechanical ventilator.

Antibiotics for bacterial pneumonia
Bacterial pneumonia is treated with antibiotics, which kill certain kinds of germs called bacteria and stop their growth. Antibiotics are only effective against bacterial infections and are not suitable for viral infections.
The type of antibiotic provided can vary based on the germs known to be in your community, as well as other health conditions you are experiencing. The choice of antibiotic is also based on the severity of the patient's illness, host factors (e.g. comorbidity, age), and the presumed causative agent.
The best initial antibiotic choice is thought to be a macrolide. Macrolides provide the best coverage for the most likely organisms in community-acquired bacterial pneumonia (CAP). Macrolides have effective coverage for gram-positive, Legionella, and Mycoplasma organisms. Azithromycin administered intravenously is an alternative to intravenous erythromycin. However, macrolides may cause gastrointestinal (GI) upset and have the potential for drug interactions.
Delafloxacin is a fluoroquinolone antibiotic available in intravenous and oral preparations that allow for an intravenous-to-oral switch. It is indicated for the treatment of community-acquired bacterial pneumonia (CABP) caused by susceptible bacteria, including Streptococcus pneumoniae, S aureus, K pneumoniae, E coli, and more. Levofloxacin is another popular choice in pneumonia treatment, which is also a fluoroquinolone used to treat CAP caused by various bacteria.
It is important to take antibiotics exactly as prescribed by your doctor and to finish the entire course of treatment, even if you start to feel better. Stopping antibiotic treatment early can cause the infection to return and increase the chances of the bacteria becoming resistant to treatment.

Intravenous fluids and oxygen therapy
Additionally, IV fluids can be used to deliver medications directly into the bloodstream, ensuring a rapid and effective delivery of antibiotics, antivirals, or other necessary drugs. This method is often employed when oral medication is not feasible or when a quick response is required.
Oxygen therapy is another crucial aspect of pneumonia treatment in hospitals. This therapy is used to improve oxygen levels in the blood, aiding patients who are struggling to breathe due to the infection in their lungs. Oxygen therapy can take several forms, including nasal cannula oxygen and invasive ventilator oxygen. The former is a less invasive method where oxygen is delivered through thin tubes placed in the nostrils, providing extra oxygen to help with breathing. Invasive ventilator oxygen, on the other hand, is a more intensive form of therapy that mechanically assists or controls a patient's breathing. This method is typically reserved for patients with severe respiratory failure or those who cannot breathe on their own.
The decision to use oxygen therapy and the specific method chosen depend on the severity of the patient's condition and their individual needs. Oxygen concentrators are often preferred for oxygen therapy as they provide a convenient and consistent supply of pure oxygen, removing the need for regular replenishment of oxygen tanks. Oxygen therapy is typically continued even after a patient returns home, with doctors prescribing the appropriate flow settings and duration of use to ensure safe and effective treatment.

Antiviral medication for viral pneumonia
Pneumonia is an inflammation of the lungs usually caused by a bacterial or viral infection. The treatment for pneumonia depends on the type of pneumonia, the patient's age, how sick they are, and whether they have other health conditions.
For viral pneumonia, a doctor may prescribe antiviral medication. However, these medications are not effective against all viruses that cause pneumonia. Antiviral agents inhibit DNA synthesis and viral replication by competing with deoxyguanosine triphosphate for viral DNA polymerase. Agents used include amantadine, rimantadine, zanamivir, oseltamivir, ribavirin, acyclovir, ganciclovir, and foscarnet. Acyclovir is used for varicella and herpes simplex pneumonia, while ganciclovir and immunoglobulin are used for immunocompromised patients with CMV pneumonia. Remdesivir and nirmatrelvir/ritonavir (antiviral agents) and 2 mRNA vaccines have been approved for the prevention and treatment of COVID-19.
In addition to antiviral medication, supportive treatments are also given to relieve coughing, fever, chest pains, and body aches. Over-the-counter medications may be recommended to treat fever and muscle pain or to help the patient breathe easier. Cough medicines should only be taken under the direction of a doctor, as coughing is one way for the body to get rid of the infection.
For mild cases of viral pneumonia, good bed rest, a balanced diet, and plenty of fluids may be all that is necessary. However, severe cases of pneumonia may require hospitalization, intravenous antibiotics or antiviral medications, and oxygen therapy or other supportive therapies.

Antifungal medication for fungal pneumonia
Pneumonia is an infection in the lungs caused by bacteria, viruses, or fungi. Treatment for pneumonia depends on the cause and severity of the infection. If the pneumonia is bacterial, it can be treated with antibiotics. Viral pneumonia usually goes away on its own and does not require medication. Fungal pneumonia, on the other hand, is treated with antifungal medications.
Fungal pneumonia is caused by an infection of fungi in the lungs. It is not contagious and is typically seen in patients with underlying diseases or compromised immune systems. The most common fungus responsible for fungal pneumonia is Candida, specifically Candida albicans. Risk factors for developing Candida pneumonia include AIDS, chemotherapy-induced neutropenia, and HM/HSCT.
Antifungal medications are used to treat fungal pneumonia. The specific antifungal medication prescribed depends on the type of fungal infection. For example, the prophylactic use of "azole" medications, such as fluconazole, has been effective in treating Candida pneumonia in immunosuppressed patients. Additionally, amphotericin B has been used to treat pulmonary candidiasis, a type of fungal pneumonia caused by Candida species. The administration of amphotericin B, in combination with flucytosine, has been recommended for critically ill patients with Candida pneumonia.
The treatment of fungal pneumonia also involves managing symptoms and ensuring proper rest. Patients are advised to control fever and body aches with medications such as aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), or acetaminophen. It is important to note that aspirin should not be given to children. Staying hydrated is crucial, as it helps loosen secretions and brings up phlegm. Warm beverages, steamy baths, and the use of a humidifier can provide relief by opening the airways and easing breathing.

Imaging examinations, blood tests, and pulse oximetry
Imaging examinations are crucial for the management of pneumonia. They serve primarily to confirm a pneumonia diagnosis, differentiate between infectious pneumonia and non-infectious diseases, and evaluate the effects of antibiotic treatment. While chest radiography is typically sufficient for diagnosis and evaluating treatment response, computed tomography (CT) is necessary to identify causative pathogens, exclude non-infectious pneumonia, and uncover underlying diseases. Imaging examinations can also suggest the possibility of tuberculosis, which requires distinct treatment approaches from common bacterial pneumonia.
Blood tests are employed to determine the cause of pneumonia and assess overall health. A blood culture test involves growing bacteria from a blood sample in a laboratory, which usually takes several days. This test helps identify bacteria and detect potential complications, such as bloodstream infections. Another blood test is the beta-D-glucan test, which aids in detecting fungal infections. A basic metabolic panel (BMP) assesses kidney function, electrolytes, and blood sugar levels. A complete blood count (CBC) measures the levels of different blood cells and can indicate elevated white blood cell levels associated with infections.
Pulse oximetry is a pulmonary function test that evaluates blood oxygen levels. It is used in conjunction with clinical rules, such as the Marchello et al. rule, to aid in the diagnosis of pneumonia. The GRACE consortium has established risk groups based on clinical judgment and the acceptance of false-negative results in diagnostic studies. Pulse oximetry, along with other vital signs and clinical examinations, helps rule out pneumonia in patients with lower respiratory tract infections.
In addition to these imaging examinations, blood tests, and pulse oximetry, the treatment of pneumonia in a hospital setting may include intravenous fluids, antibiotics, oxygen therapy, and other breathing treatments. The specific treatment plan depends on the type of pneumonia, the patient's overall health, age, and severity of symptoms.
