All we need to know about the ICU Ventilators

ICU ventilators feature as the last hope of an individual struggling for survival. Physicians after trying hard to save a person’s life have no other option but to shift him/her on to a ventilating machine.

Today, the demand for ventilators has peaked drastically. The Covid-19 medical emergency has engendered the medical service providers to supply adequate ICU ventilators to the patients in discomfort.

However, a lack of supply has caused an emergent need to manufacture more such medical devices for the population. Due to this lack, many hospitals try to simultaneously use a single ventilator for two patients.

This article discusses the definition, features, importance, and the working dynamics of an ICU ventilator. It also delineates its manufacturers and service providers in India.

What is an ICU Ventilator?

An ICU ventilator is a medical machine that aids patients suffering from breathing ailments. The ventilation device facilitates proper inhaling and exhaling process and helps an individual to balance out their breathing.

These remarkable and massively durable medical instruments cure people in distress especially those suffering from lung issues, stroke, cardiac problems, brain injury, pneumonia, etc.

In contemporary times, ICU ventilators are the best medical devices to fight COVID- 19. Generally used in an ICU (Intensive Care Unit) set up and during the period when a person is unable to maintain their breathing, these ventilating machines are a non-invasive device to furnish respiratory support to such patients.

And if the condition of a patient turns severe, the physicians attach an invasive tube to the ventilator or a person’s neck in order to allow him/her to use it conveniently.

Working Principle of an ICU Ventilator

A typical ICU ventilator operates on the breath in (oxygenation), breathe out (ventilation) principle. Oxygenation refers to the process of inhaling pure oxygen from the ambient atmosphere while ventilation is the process of exhaling unwanted and harmful carbon dioxide.

The different components dedicated to performing specific functions in an ICU ventilator are as follows:

  • Monitor: To monitor the amount of oxygen that the patient receives

  • Nasogastric tube: It passes oxygen from a person’s nose to the stomach

  • Endotracheal tube: It passes oxygen from an individual’s mouth to the windpipe

  • A set of Humidifiers: To moisten the breathable air

  • Other Fixated Tubes: To cater to the passage of carbon dioxide out of a patient’s body

Besides, there are both electricity-driven and battery-powered ventilators in the Indian markets.

Uses of an ICU Ventilator

An ICU ventilator is used during the following medical scenarios:

  • During surgery: Ventilators are often used while a physician conducts a surgery. This is because patients require an extra breathing support system while dozed with anesthesia.

  • Recovering from surgery: Patients who have had a surgery recently may require a ventilator to harmonize their breathing

  • Breathing Issues: Patients suffering from breathing ailments including respiratory diseases require the service of ICU ventilators

In addition to the above, ventilators find usage in medical conditions such as:

  • Coma or loss of consciousness

  • Amyotrophic lateral sclerosis

  • Chronic Obstructive Pulmonary Disease

  • Lung infection

  • Drug overdose

  • Myasthenia gravis

  • Polio

  • Premature lung development (in infants)

  • Upper spinal cord injuries

Side-Effects of an ICU Ventilator

Despite having numerous, using a ventilator involves certain risks. Some of the potential side-effects of an ICU ventilator are:

  • Sinus infection

  • Skin irritation

  • Cough and cold

  • Issues in the vocal cord

  • Oxygen toxicity due to extra oxygen in the lungs

  • Blood clots

The patients must consult their physicians at the earliest in case they encounter any of the above-mentioned problems.

Other Requirements while on the Ventilating Machine

Being on a ventilator may be uncomfortable. Patient breathing through this machine is unable to talk or eat properly. Here are a few requirements which need to be attempted in addition to the ventilating system:

  • Medicines as prescribed by your physician. This can include pain killers, muscle relaxers and sedatives

  • Other medical equipment to monitor heart rate, blood pressure, oxygen saturation, and respiratory rate

  • X-ray and chest scans

Technical Components of an ICU Ventilator

An ICU ventilator constitutes essential technical components to facilitate adequate breathing. Some of the important components are:

  • High-performance PSOL valves

  • Graphical display screens

  • Tiltable and rotatable monitor

  • Pre-defined flow sensor positions

  • Backup ventilation facilities

  • VCO2 and ECO2 monitoring systems

  • Auto-control user interface

  • Approved as per normative medical standards

Ventilation modes -

  • Pediatric mode.

  • Controlled mode.

  • Asst. Controlled mode.
