What are Non-Invasive Ventilators and Its Benefits?

Non Invasive ventilators are medical equipment that helps deliver oxygen via a face mask, eliminating the need for an endotracheal airway.

NIV has shown effective results in treating the less severe respiratory problem in COVID-19 patients and other respiratory failures. NIV creates positive airway pressure- this means, the pressure outside the lungs being more than the pressure inside the lungs. It causes air to enter the lungs forcefully, lessening the respiratory effort, and reduces the work of breathing. It helps to keep the chest and lungs expanded by increasing the functional residual capacity.

Advantages of Non-Invasive Ventilators

Below are a few advantages of NIV.

Decreased Cost

In the course of COVID-19 treatment, NIV has reduced cost as compared to Invasive ventilators. However, it doesn’t reduce the cost entirely as the patient using NIV will still require it during his journey of treatment. But the availability of NIV may require fewer nursing and medical resources.

Although NIV’s equipment cost is virtually the same as the invasive ventilators because it uses the same ventilators and the same humidified, cost savings for patients and hospitals are in terms of personnel, as one doesn’t need airway experts, nurses or dedicated medical staff.

Delivery Of Controlled Oxygen

A significant contribution in NIV is managing respiratory failure and delivering controlled oxygen to the patient’s lungs. Due to its tight mask strapped on the face, it allows the patient to get the oxygen concentration, which the doctor prescribes finally.

Even with all its faults, NIV masks are a tightly fitted thing that seals the airway together with the ventilator circuit. The pressure is therefore applied is fair with the expectation that the ventilator will deliver that pressure, or at least alarm loudly if it cannot.

The transition from invasive ventilators

The conversion from using an artificial airway to using NIV for patients with the respiratory problem was not easy. The reduced tolerance of conventional oxygen therapy of invasive ventilators became the stepping stone of NIV. The non-invasive ventilator act as a bridge to respiratory normality, preventing reintubation in some groups of patients.

NIV Is Better

Researches have shown that it is reasonable to say that NIV is better than invasive ventilators. Invasive ventilators are well tolerated by comatose intubated people who are under the effects of the anesthetic. Patients with less breathing problems remain comfortable with minimal or no sedation with invasive ventilators. Instead, it is correct to say that non-invasive ventilators are more convenient for patients with respiratory issues or have coronavirus symptoms.

Here are a few more points about NIV

1. It doesn’t require sedation or muscle relaxant to commence.

2. The mandatory mode is generally not in use in the ventilation, and patient-triggered ventilation provides comfort to any patient.

3. Non-invasive ventilators can be discontinued and re-commended, allowing breaks from ventilation.

4. It is safe and feasible to use.

How Is NIV Usefull for Coronavirus Patients?

New medical evidence has shown the benefits of Non-invasive ventilators for the use of less severe cases of COVID-19 related respiratory problems globally. Pieces of evidence from both China and Italy, experts say many coronavirus patients will less-severe respiratory distress could benefit from non-invasive ventilation therapy. Thus, more invasive ventilation devices for the most critically ill patients. NIV is a game-changer in the race of ventilators in the hospitals as the majority of COVID patients benefit from these respiratory devices, easing pressure in hospitals and offering others lifesaving options.

According to the CDC, patients with mild symptoms of COVID-19, many not initially require hospitalization; however, when their symptoms worsen and require oxygen supplementation, then NIV is appropriate.

Due to the over-demand of ventilators around the world, governments and health administrations may now use NIV in patients with confirmed COVID-19. Non-invasive ventilators can fulfill hospitals’ capacity and insufficient availability of equipment to meet the demand of COVID patients. It is a way to forestall the need for intubation and reduce days on a ventilator in the therapy for COVID-19 patients.
