Pneumonia is a lung infection caused by bacteria, viruses, or fungi. It can be a potentially serious condition, and in severe cases, a hospital stay may be required. Bacterial pneumonia tends to be more common and more severe than viral pneumonia and is more likely to require hospitalisation. However, viral pneumonia can also lead to hospitalisation in severe cases. Factors such as age and underlying health conditions also play a role in determining the need for hospitalisation. During a hospital stay for pneumonia, patients typically receive intravenous fluids, antibiotics, and oxygen therapy.

What You'll Learn
Hospital-acquired pneumonia
Pneumonia is an infection of the lungs, usually bacterial or viral, causing fluid and inflammation in the lungs, making breathing difficult. It is often treated with antibiotics and rest, and most people recover within 2-4 weeks. However, pneumonia can be more severe in young children, older people, and those with other health conditions, who may require hospitalisation.
HAP is often associated with the use of ventilators, with over 90% of cases occurring in patients who are intubated and mechanically ventilated. It can also be spread by healthcare workers through their hands, clothing, or instruments. The risk factors for developing HAP include aspiration of upper respiratory tract secretions during sleep, the use of acid-suppressive medications, and the presence of certain pathogens, such as aerobic gram-negative bacilli. The management of HAP requires an interprofessional team of specialists, including infectious disease experts, pulmonary disease specialists, and critical care clinicians.
The first signs of HAP may include mental changes or confusion, especially in older adults. Tests such as arterial blood gas measurements, blood cultures, and chest X-rays or CT scans may be ordered to confirm the diagnosis. Treatment for HAP typically includes intravenous antibiotics and oxygen therapy to improve breathing and remove thick mucus from the lungs. However, HAP can be life-threatening, and long-term lung damage may occur. Therefore, preventing the spread of germs in hospitals is crucial, including handwashing, wearing gowns, and following safety protocols.

When to go to the hospital
Pneumonia is a potentially serious condition that affects the lungs. It is usually caused by an infection, which can be bacterial, viral, or fungal. While most people recover from pneumonia, it is important to know when to seek hospital treatment.
If you are diagnosed with pneumonia but your symptoms are not severe, your doctor may advise you to manage it at home. Home remedies include drinking fluids such as water or warm tea to help remove mucus from the lungs, taking over-the-counter pain or fever medications, and getting plenty of rest.
However, pneumonia symptoms can vary in severity, and sometimes it can be difficult to differentiate pneumonia from other respiratory conditions such as the flu or a cold. If your symptoms worsen, it is important to seek medical attention.
You should go to the hospital or call an emergency number if you are experiencing any of the following symptoms:
- Breathing difficulty
- High fever
- Persistent cough
- Chest pain
- Mental state changes, such as confusion
- Bloody or unusually coloured mucus
- Pale, blue, or blotchy skin, lips, or tongue
In severe cases, patients may be hospitalized and kept under observation. Treatment in the hospital may include intravenous antibiotics, oxygen therapy, and respiratory therapy.

Treatment in hospital
Treatment for pneumonia varies depending on the cause and severity of the infection. Pneumonia is an inflammation of the lungs caused by bacteria, viruses, or fungi. While it is not always necessary to go to the hospital for pneumonia, bacterial pneumonia is often more severe and may require hospitalisation. Young children, babies, older people, and people with heart or lung conditions are also more likely to be admitted to the hospital for pneumonia.
If you are hospitalised for pneumonia, you will likely be given intravenous fluids (IV) and antibiotics to treat the infection. Antibiotics are used to fight the bacteria causing the infection and are usually prescribed for bacterial pneumonia. Oxygen therapy may also be administered to help you breathe. In more severe cases, a ventilator may be required to support breathing.
Healthcare professionals will monitor your vital signs, including respiratory rate, temperature, and heart rate. Chest x-rays and blood tests may also be performed to check for improvements and to rule out other conditions.
In addition to medical treatments, rest is essential for recovery. It is important to avoid overdoing daily activities and to get plenty of help with meal preparation and household chores until you feel stronger.
It is worth noting that hospital-acquired pneumonia can be very severe and even fatal. This type of pneumonia occurs when a patient develops a lung infection during their hospital stay, and the infecting organisms tend to be more dangerous and resistant to treatment.

Recovery time
For severe cases requiring hospitalisation, recovery can take anywhere from one to six months. Factors that can influence recovery time include underlying health conditions, age, and functional status (how easy it is for a person to perform daily tasks).
It is important to take all your prescribed medications and to get plenty of rest and sleep. Drinking plenty of liquids is also recommended, but alcohol should be avoided. Keeping physically active can help speed up recovery, but strenuous activity should be avoided as it may cause dizziness.

Preventing pneumonia
Pneumonia is a lung infection caused by bacteria, viruses, or fungi. It can be prevented in many cases, and there are several steps you can take to reduce your risk of getting pneumonia.
Firstly, vaccinations can help prevent pneumonia. The pneumococcal vaccine is recommended for babies, adults over 65, and those at higher risk of pneumococcal infections. The flu vaccine is also recommended for these groups, as well as for pregnant women. The RSV vaccine is advised for adults aged 75 to 79 and during pregnancy, and the COVID-19 vaccine is for those at increased risk of the virus. For children, several vaccines help prevent infections caused by bacteria and viruses that can lead to pneumonia.
Secondly, good hygiene practices are essential. Wash your hands frequently with soap and water, especially before eating or preparing food, and after using the restroom or coughing and blowing your nose. Use an alcohol-based hand sanitizer if soap is unavailable. Additionally, avoid close contact with sick people, and take steps to improve indoor air quality.
Thirdly, quitting smoking is crucial in preventing pneumonia. Smoking damages your lungs and makes it harder for them to defend against germs, increasing the likelihood of infection.
Finally, keep your immune system strong. Get regular physical activity, eat healthily, and consider taking antibiotics if your immune system is weakened, as this can prevent bacteria from growing in your lungs.
While pneumonia can be serious and sometimes life-threatening, taking these preventative measures can significantly reduce your risk of contracting the infection.

Frequently asked questions
Symptoms of pneumonia include fever, cough, fatigue, shortness of breath, chest pain, and mental state changes. In young children, additional symptoms may include high fever, bloody or unusually coloured mucus, and congestion or chest pain.
Pneumonia can be treated at home with rest, hydration, and over-the-counter pain or fever medications. However, if symptoms worsen or become severe, such as breathing difficulty, high fever, persistent cough, or mental state changes, it is necessary to go to the hospital or call an ambulance.
In the hospital, patients with pneumonia are typically administered fluids and antibiotics intravenously and may be given oxygen therapy to aid breathing. Respiratory rate, temperature, and heart rate are monitored, and tests such as X-rays and blood tests may be performed to check for improvements and rule out other conditions.
