When you hear the news that a person you love needs a ventilator, it is normal if you want to know how it will affect the life of the person you love. You may have a general idea of what a medical ventilator is. This is a machine that helps patients who cannot breathe. In this article, we will learn more about the ventilator, from how it works, and what to expect on the ventilator.


The following knowledge points are listed below:

What happens when using a ventilator

1. What is a ventilator

A ventilator is a machine that supports breathing. These machines are mainly used in hospitals. The ventilator sends oxygen into the lungs, removes carbon dioxide from the body, helps patients breathe easier, and breathes for those who have lost their ability to breathe independently.

The ventilator is usually used for a short period of time, such as during surgery under general anesthesia, or in the treatment of severe lung diseases or other conditions that affect normal breathing. Some people may suffer from a condition that requires long-term use of a ventilator or even a lifelong ventilator.

2. How does the ventilator work

The ventilator uses pressure to blow air into the lungs. This pressure is called positive pressure. Patients usually exhale by themselves, but sometimes the ventilator also exhales for them.

The amount of oxygen the patient receives can be controlled by a monitor connected to the ventilator. If the patient’s condition is particularly fragile, the monitor will be set to alert the caregiver to indicate an increase in air pressure.

This machine works by delivering oxygen to the lungs and expelling carbon dioxide from the lungs. This allows patients with difficulty breathing to get the right amount of oxygen. It also helps the patient's body heal because it eliminates the extra energy of breathing difficulties.

The ventilator blows air into the airway through the breathing tube. One end of the tube is inserted into the patient's trachea, and the other end is connected to the ventilator. The breathing tube functions as an airway by letting the air and oxygen in the ventilator flow into the lungs. According to the patient's physical condition, they can use a breathing mask instead of a breathing tube.

3. What happens when using a ventilator

What to expect depends on the severity of the patient's condition. For example, some people can resume normal activities, such as reading or watching TV, while others need to restrain themselves to prevent them from pulling out their breathing tubes.

The patient or caregiver also needs to learn how to provide suction to prevent mucus from blocking the catheter.

Ventilators usually cause no pain. The breathing tube in the patient's airway may cause some discomfort. One of the most frustrating things about using a ventilator is that the patient cannot talk and eat. The health care team can provide nutrition through a tube inserted into a vein instead of food. If patients use the ventilator for a long time, they may eat through the nasogastric tube or feeding tube.

The ventilator greatly restricts the activities of patients and restricts their activities. They can sit on a bed or chair, but usually cannot move too much.

The silver lining of this situation is that the ventilator will not cause any pain to the patient. However, there is a transition period where patients may experience some discomfort as they adjust to the device. Once the patient's condition improves, there is usually a period of "weaning", allowing the patient to get used to breathing by themselves, and then take out the ventilator.
