How To Prevent Ventilator Pneumonia?

Ventilator pneumonia or ventilator-associated pneumonia (VAP) is a lung infection. It happens in people who use a breathing machine. It takes 48 hours or more to show symptoms after taking on a ventilator. Almost 10–20% of patients who use ventilator suffers from ventilator-associated pneumonia (VAP).

Fever, cough, chest pain, and trouble breathing are the common sufferings. Sometimes, it can be so dangerous that it can even cause death in some cases. But it is a matter of great joy that it can be prevented by following some strategies. For example, good hand washing, cleaning the mouth, raising the head of the bed, and checking the patient often.

What Are the Main Causes of Ventilator-Associated Pneumonia?

As we already told you, ventilator-associated pneumonia (VAP) is a serious lung infection for people who use breathing machines for more than 48 hours. It can cause some serious suffering like high fever, breathing problems, and so on. To prevent this infection, you should know the causes.

1. Bacteria Entering the Lungs

A tube is used in a ventilator, which goes into the patient’s windpipe so they can breathe. But the sad part is the tube can carry bacteria from the mouth, nose, or throat into the lungs. But on the other hand, the normal ways of cleaning out germs are blocked by the tube. For this reason, bacteria can grow much quicker in the lungs. This means that the risk becomes higher as long as the tube stays in.

2. Poor Oral Hygiene

Germs build up on the teeth, tongue, and gums if the mouth isn’t cleaned well. The breathing tube can be moved down by the germs. There are several ways to get rid of bacteria. Brushing the teeth, cleaning the gums, and using mouthwash like chlorhexidine is essential for killing bacteria. Oral care is very crucial. It should be done every 4-6 hours.

3. Lying Flat in Bed

Saliva or stomach contents can enter the lungs when a patient lies flat, and this is called aspiration. Aspiration is very dangerous and one of the leading causes of VAP. However, there are several ways to prevent aspiration. While sleeping, keep your head on the bed raised at 30 to 45 degrees. So it prevents fluids from going into the lungs.

4. Dirty Hands and Equipment

If doctors, nurses, or caregivers play an essential role here. They can spread germs if they touch the patient or equipment without washing their hands properly. Also, the tubes, suction tools, or other devices should be cleaned or changed regularly and adequately because they can be responsible for carrying harmful bacteria. Washing hands and cleaning equipment properly are excellent practices to prevent infection.

5. Extended Use of the Ventilator

The chance of getting VAP increases if the patient stays on a ventilator for an extended time. Because the germs take more time to grow in the lungs, this is why doctors and nurses check every day to see if the patient is ready to breathe on their own. A ventilator is crucial to save a patient’s life, but it is better to remove the ventilator from a patient as early as possible to prevent VAP or ventilator-associated pneumonia.

What are the signs that a ventilated patient might have pneumonia?

Here are some signs that a ventilated patient might have pneumonia:

∆ Fever: High temperature in the body or fever is a common sign.

∆ Increased White Blood Cells: A high white blood cell count is a sign of VAP. It indicates the body is fighting against infection.

∆ Cough with Secretions: Yellow, green, or smelly mucus from the lungs is a potential sign of VAP while bringing up the tube.

∆ Low Oxygen Levels: If the patient needs more oxygen to breathe normally, then it is a good sign of VAP.

∆ New Lung Sounds: Doctors hearing crackles or wheezing in the lungs using a stethoscope is a potential sign.

∆ Chest X-ray Changes: White patches or fluid in an X-ray result is a sign of VAP.

∆ Increased Heart Rate: One of the common signs of VAP is increasing heartbeat.

∆ Breathing Difficulty: The patient will face difficulty breathing even if he is on the ventilator.

How To Prevent Ventilator-Associated Pneumonia?

As we already said, ventilator-associated pneumonia or VAP can be dangerous, even if it can be the cause of death. However, VAP can be easily prevented by ensuring proper care. Here are some of the most effective ways to prevent ventilator-associated pneumonia or VAP.

1. Hand Hygiene

Hand washing is very important to prevent infection. Ensure that the doctors, nurses, and your family must wash their hands before touching you. The case is not only before; the hand should be cleaned after any procedure. For example, suctioning or changing the ventilator tube. Alcohol-based hand rubs or soap and water kill most germs.

2. Oral Care

To stop the growth of bacteria, a clean mouth is very crucial. Make sure that your nurses are brushing your teeth, tongue, and gums regularly. Tell them to do this every 4 to 6 hours. A special mouthwash like chlorhexidine, can be beneficial as it kills almost all the harmful germs. If you maintain poor oral care, the germs can easily enter your lungs through the breathing tube.

3. Daily Check for Ventilator Removal

Make sure your doctor and nurses are checking you every day. If you think you are strong enough, tell them to remove the ventilator early because it reduces the chance of pneumonia. But if you are on a ventilator for a longer time, then the risk of VAP increases. So, it is better to remove the ventilator as early as possible.

4. Clean Equipment

To avoid infection, make sure that the ventilator tubes, suction tools, and other devices are being cleaned properly. Also, it is essential to dry them after cleaning. Because germs can grow on dirty or wet equipment and eventually go into the patient’s lungs. The proper maintenance of each piece of equipment is crucial to prevent ventilator-associated pneumonia or VAP.

5. Suctioning Secretions

Mucus can block air and carry germs. The nurse will use a suction to remove mucus from the mouth and airway. Some breathing tubes have special openings for continuous suctioning above the lungs. It prevents fluids from going down into the lungs and causing pneumonia.

If you’re worried about ventilator-associated pneumonia, the Hingmed Auto BiPAP Therapy HM-ST30 is the best choice for safer breathing. It offers five smart modes such as S, T, ST, Auto-S, and CPAP. It helps lower the risk of ventilator pneumonia by providing non-invasive ventilation. For real-time remote monitoring, the Hingmed Health App and SmartView Cloud are available. The HM-ST30 is perfect for both home and hospital care as it has advanced features and comfort settings, and it is easy to use.

How Can Family Members Contribute to Preventing Ventilator-Associated Pneumonia?

To prevent ventilator-associated pneumonia (VAP), family members can play an important role. They can support in many helpful ways apart from medical care. Before and after touching the patient, they should always wash their hands. Hygiene is essential to prevent the spread of germs that can cause infection. They can clean the patient’s mouth or remind the nurses to do oral care.

A clean mouth lowers the number of germs that can enter the lungs through the ventilator tube. They should also make sure the patient’s head is raised. If the patient is lying flat, family members can inform the nurse. Keeping the head raised helps prevent fluids from going into the lungs.

Talking to the patient and encouraging deep breathing or movement can also help. Light movement can improve breathing and lower infection risk.

Conclusion

Ventilator-associated pneumonia is a severe infection, but prevention is easier with proper care. Some simple steps like washing hands, cleaning the mouth, raising the head of the bed, and checking the patient daily can create a big difference. Also, using clean equipment and removing the ventilator as early as possible reduces the risk. Family members do basic care or stay alert all the time. Preventing ventilator pneumonia is not hard. It just needs care, attention, and united efforts.

FAQ’s

What role does oral care play in preventing VAP?

Oral care keeps the mouth clean. It reduces harmful bacteria. It helps to stop germs from entering the lungs through the ventilator tube. Eventually, it lowers the risk of pneumonia.
