What is Ventilator? What are some common Types of Ventilators

Ventilator: Medical equipment that most people have heard about. It is one of the most common tools in critical care, often seen in Intensive Care Units (ICUs). Healthcare professionals use ventilators for patients who have difficulty breathing on their own.

So, for students who aim to head into the critical care environment, learning about ventilators and taking care of patients with artificial airways is crucial.

Let’s learn about ventilators in detail.

What Do Ventilators Do?

A ventilator is a device that supports or recreates the process of breathing by pumping air into the lungs.  Additionally, a ventilator: 

Helps remove carbon dioxide from your lungs.

Provides pressure to keep the small air sacs in your lungs (alveoli) from collapsing.

The ventilator is used in scenarios where patients experience respiratory failure. When this occurs, a person cannot get enough oxygen, which can be life-threatening.

The following are the injuries that cause respiratory failure:

Sudden cardiac arrest

Lung disease

Spinal cord injury

Head injury

Stroke

Neonatal respiratory distress syndrome

Acute respiratory distress syndrome (ARDS)

Sepsis and more.

Remember: Patients with different causes of respiratory failure require different ventilators. So, it is also essential to know about its various types.

Some Common Types of Ventilators

Pressure-limited assist control (PAC) ventilation

PAC ventilation is a type of mechanical ventilation mode that delivers a breath to the patient based on a pre-set inspiratory pressure (IP) limit. The ventilator will continue to deliver gas until a set pressure is reached, ensuring a breath is delivered regardless of the patient's lung resistance or compliance.

How it works:

The patient initiates a breath effort, triggering the ventilator.

The ventilator delivers gas flow until the set inspiratory pressure limit is reached.

The ventilator then cycles off to allow for exhalation.

The patient can breathe spontaneously between ventilator breaths.

 Synchronized intermittent mandatory ventilation (SIMV)

SIMV ventilation is a mode that combines mandatory breaths delivered by the ventilator at a set rate with the patient's spontaneous breathing efforts.

How it works:

The ventilator delivers a set number of breaths per minute (rate) regardless of whether the patient initiates a breath or not (mandatory breaths).

The ventilator synchronizes the delivery of mandatory breaths with the patient's spontaneous breaths whenever possible.

The patient can also breathe spontaneously between mandatory breaths.

Volume-limited assist control (VAC) ventilation

VAC ventilation is a mode that delivers a pre-set tidal volume (VT) to the patient with each breath. The ventilator will cycle off to exhalation once the set VT is delivered, regardless of the pressure reached.

How it works:

The patient initiates a breath effort, triggering the ventilator.

The ventilator delivers a set volume of gas (VT) into the lungs.

The ventilator then cycles off to allow for exhalation, even if the set pressure limit is not reached.

The patient can breathe spontaneously between ventilator breaths.

Above, we tried to give a basic idea about ventilators and their types; if you want to get more detailed information, including the resources, enrol in the Online Critical Care Course created by DigiNerve.

Do you think shockwave would purr?? I would think his anatomy as a car-like creecher would at least make something adjacent 👀

You're absolutely right though because human machines can make all kinds of noises, like laptop fans and car engines, so it makes sense that a living machine could do the same. The engine even makes a sound similar to purring!

In most cases, Shockwave turns into a tank, so that's a big boy right there. The purring would probably be just as strong and rumbly 🥰

I mean, cool, but half my mind goes back to the urban legend about the serial killer who covered his victims in paint and waited for them to suffocate.

I can appreciate the concept, but the logistics of this make my skin crawl. Skin needs to breathe!

Lil Nas X said “Choupette does demon twink made out of diamonds and glitter” and the world said yes. Men what’s stopping you from dressing like this every day? THIS is what men need to be wearing on the red carpet!
