SO, WHAT DOES A VENTILATOR DO?
The Newport HT70 Ventilator is a form of life support that takes over the work of breathing when a person is not able to breathe enough on their own. Also called a breathing machine, there are many reasons why a patient may need a ventilator. Low oxygen levels or severe shortness of breath from an infection such as pneumonia are the most common reasons.
WHEN ARE VENTILATORS PUT TO USE?
Mechanical ventilation is typically used on a temporary basis, such as during surgical procedures. When a patient is under general anesthesia, their normal breathing may be disrupted. A ventilator is used to ensure the patient continues to breathe while asleep during surgery.
A person with serious lung disease or other medical condition that interferes with normal breathing may need to use a ventilator until they recover. This type of care is commonly provided in the intensive care unit (ICU) or critical care unit (CCU) of a hospital. Though those who need it for a longer period of time may be in a different part of the hospital, at a rehabilitation facility, or even at home.
EXAMPLES FOR NEEDS OF VENTILATORS
- Respiratory infections like pneumonia, influenza (flu), and coronavirus (COVID-19)
- Lung diseases like asthma, COPD (chronic obstructive pulmonary disease), cystic fibrosis, and lung cancer
- Acute respiratory distress syndrome (ARDS)
- Damage to the nerves and/or muscles involved in breathing (can be caused by upper spinal cord injuries, polio, amyotrophic lateral sclerosis, myasthenia gravis, etc.)
- Brain injury
- Drug overdose
HOW DO MECHANICAL VENTILATORS WORK?
Normally, when someone takes a breath, their chest wall expands which creates negative pressure inside the lungs that draws air in. When a person can’t pull the breaths in on their own due to sickness or weakness, a ventilator creates positive pressure that forces air into the lungs. The first step in putting a patient on a ventilator is general anesthesia. Then, a medical professional will insert a tube through the mouth or nose and into the windpipe. This is called intubation.
Then the tube is connected to an external machine that blows air and oxygen into the lungs. The machine can help do all or just some of the breathing, depending on the patient’s condition. The ventilator can also help hold the lungs open so that the air sacs do not collapse. While patients are on a ventilator, doctors will monitor their heart and respiratory rates, blood pressure, and oxygen saturation.
DIFFERENCE BETWEEN INVASIVE AND NONINVASIVE VENTILATORS (NIV)?
Invasive ventilation delivers air via a tube into the windpipe through the mouth or sometimes the nose. Invasive ventilation is the standard treatment in use for people with neuromuscular diseases or chest wall disorders who are suffering from acute respiratory failure.
On the contrary, a noninvasive ventilator uses no tubes, instead delivering oxygen using a tight-fitting mask attached over the patient’s mouth and nose. Some masks are designed to cover the nose only and are known as nasal masks. Another noninvasive option is a hood that encloses the entire head versus a mask covering the nose and/or mouth. None of these delivery options requires physical “invasion” of the patient’s body, thus the term: noninvasive.
There are also ventilators like the Newport HT70 that offer both invasive and noninvasive options.

A shortage of ventilators is expected in the coming days as more people are admitted to hospitals needing breathing assistance in intensive care units. Nonetheless, ventilators can be life-saving and, indeed, many of those who’ve survived severe cases of diseases like COVID-19 would be unlikely to have made it without one.
