Introduction
In the midst of the COVID-19 pandemic, the terms “oxygen” and “ventilator” have become commonplace in our daily conversations. While they are both used to assist patients with respiratory problems, there are significant differences between the two. In this article, we’ll explore the functions of oxygen and ventilator and how they differ from each other.
What is Oxygen?
Oxygen is a gas that is essential for human life. It is breathed in through our lungs and transported to our body’s cells. Oxygen therapy is a common treatment for patients with respiratory problems such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. Oxygen therapy can be delivered through a mask or nasal cannula, and it helps to increase the amount of oxygen in the patient’s blood.
What is a Ventilator?
A ventilator is a machine that helps patients who are unable to breathe on their own. It is commonly used in intensive care units (ICUs) to support patients with severe respiratory failure, such as those with COVID-19. A ventilator delivers oxygen to the patient’s lungs through a tube that is inserted into the windpipe. The machine also helps to remove carbon dioxide from the patient’s body by controlling the rate and depth of breathing.
The Differences Between Oxygen and Ventilator
While both oxygen and ventilator are used to assist patients with respiratory problems, there are significant differences between the two. Oxygen therapy is a non-invasive treatment that delivers oxygen to the patient’s lungs through external devices such as masks or cannulas. It is used to increase the amount of oxygen in the patient’s blood and is often used in conjunction with other treatments.
A ventilator, on the other hand, is an invasive treatment that requires a tube to be inserted into the patient’s windpipe. It delivers oxygen directly to the patient’s lungs and also helps to remove carbon dioxide from the body. A ventilator is used when the patient is unable to breathe on their own or when they require assistance to breathe.
When is Oxygen Used?
Oxygen therapy is used to treat patients with respiratory problems such as asthma, COPD, and pneumonia. It is also used to increase the amount of oxygen in the blood of patients who have low oxygen levels due to other medical conditions such as heart failure.
When is a Ventilator Used?
A ventilator is used to assist patients who are unable to breathe on their own, such as those with severe respiratory failure. It is also used during surgery to help patients who are under anesthesia and cannot breathe on their own.
Complications and Risks
Oxygen therapy is generally safe, but it can cause complications such as dry nose, mouth, and skin. It can also cause lung damage if the patient is given too much oxygen for too long.
A ventilator is a more invasive treatment and carries more risks than oxygen therapy. Complications can include infection, lung damage, and pneumothorax (collapsed lung). There is also a risk of ventilator-associated pneumonia, which is a type of lung infection that can develop in patients who are on a ventilator for an extended period of time.
Conclusion
In summary, oxygen and ventilator are both used to assist patients with respiratory problems, but they differ significantly in their functions and applications. Oxygen therapy is a non-invasive treatment that delivers oxygen to the patient’s lungs through external devices, while a ventilator is an invasive treatment that requires a tube to be inserted into the patient’s windpipe. Both treatments have their own complications and risks, and their use is determined by the patient’s specific medical condition.
