Functioning of a Medical Ventilator: Everything You Should Know

A ventilator is a certain type of machine that helps your lungs function properly. If you or any of your family members face difficulties during breathing, this respirator will act as a saviour. A medical ventilator pushes the air in and out of your lungs. It enables the body to receive an adequate amount of oxygen. You need to wear a fitted mask to get oxygen from the breathing machine into your lungs.

Types of Breathing Ventilators

There are multiple types of medical respirators, as listed below:

  1. Critical care ventilator
  2. Emergency and transport ventilator
  3. Multipurpose respirator

When Do You Need a Ventilator?

Various types of health conditions cause difficulties in breathing. Under such circumstances, you need a ventilator support system:

  1. Acute Respiratory Distress Syndrome (ARDS)
  2. Chronic Obstructive Pulmonary Disease (COPD)
  3. Brain injury
  4. Asthma
  5. Pneumonia
  6. Stroke

How Does a Medical Ventilator Work?

Here’s an overview of how a respiratory ventilator works:

  1. Patient connection: Initially, the patient is connected to the machine with a breathing circuit. Usually, the linkage is created via an endotracheal tube. However, it is dependent on the type of ventilation and the patient’s condition.
  2. Air intake: The respirator draws air from the surroundings. The air composition can be modified as per the patients’ requirements.
  3. Airflow regulation: The breathing machine controls the amount of oxygen to ensure the patient receives the right amount of breaths per minute.
  4. Positive pressure ventilation: The artificial ventilator pushes air into the patient’s lungs at a higher pressure. It overcomes the hindrances in the respiratory system and ensures the lungs are inflated.
  5. Exhalation: The life support machine allows the patient to exhale by removing the air or releasing the pressure from the lungs.
  6. Monitoring and adjustments: Respirators come with monitors and sensors that analyse diverse parameters like the oxygen concentration, tidal volume, and patient’s respiratory rate.

How Long Do You Require to be on the Ventilator?

The period of time you will be on the ventilator depends on the reason you require assistance with breathing. If you need a ventilator support system during surgery, you will be on it when you are drowsy. The time range will be from less than an hour to several hours.

If you require a respirator for a particular health condition, you may need it for hours, days, weeks, or more. When your lungs get stronger and you can breathe properly, you don’t need the ventilator anymore.

A gadget called a medical ventilator aids in the functioning of your lungs. If you have a medical condition that affects your ability to breathe correctly or when you cannot breathe on your own, this device may save your life.

A ventilator aids in forcing air into and out of the lungs so that your body can receive the oxygen it requires. You could put on a fitting mask to help deliver oxygen from the ventilator into your lungs. Or, if the severity of your disease warrants it, a ventilator may be placed down your neck to oxygenate your lungs.
Ventilators are most frequently used in hospitals. A physician or respiratory therapist will manage the quantity of oxygen injected into your lungs.

What makes a ventilator necessary?

Respiratory failure is the medical term for being unable to breathe correctly and is a serious emergency.

Your brain, heart, liver, kidneys, and other organs won’t be able to perform as they should if they don’t receive enough oxygen. You can acquire the oxygen your organs require by using a ventilator.

How long should you use a ventilator?

If a ventilator is required during surgery, it is typical that you will  use it only when you are in a snooze state. This could last anywhere from a few seconds to a few more hours.

You could use a ventilator for several hours, days, weeks, or even longer if you need one for a medical reason. It varies depending on how long your lungs take to develop strength and independence.

What to anticipate on a ventilator?

It can be exceedingly painful to be on a ventilator while awake, especially if it includes a breathing tube through your throat. While attached to the ventilator, you cannot speak, eat, or move about.


If you’re on a ventilator, your doctor may prescribe medication to make you feel more at ease and relaxed. This lessens the trauma of using a ventilator. The most typical medications administered to patients on a ventilator are as follows:
Painkillers, sedatives, muscle relaxants and sleep aids.
These substances frequently lead to disorientation and sleepiness. Once you stop taking them, the symptoms will fade. Once you’ve finished using the ventilator, you won’t require more medication.

Renting Or Purchasing Medical Equipment – Which Is More Feasible?

Renting Or Purchasing Medical Equipment - Which Is More Feasible?

ECG Machine

It is a challenging decision for hospitals to buy medical equipment as soon as the need arises. There are budget constraints that hold back the decision. Moreover, to smoothly run a hospital, numerous medical equipment pieces are necessary; however, not all hospitals receive the same amount of funding. To prioritise a purchase decision, the facilities and management of the hospitals have to compromise in some other departments.

Hence the hospitals should purchase medical equipment pieces from authentic medical equipment dealers in Kolkata. There are instances where the hospitals end up opting for renting options instead of purchasing the equipment pieces. This can be the case when the equipment might be required temporarily.

Which is a wiser decision? To know more, read on.

Factors determining the need for renting or purchasing medical equipment

Amount of budget allocated

The budget constraint is a significant reason that provokes medical facilities to rent medical equipment over purchasing. If the hospital’s funds are less and new technologies are needed, they prefer renting the equipment instead of funding the same. This helps the hospital to get hold of all necessary equipment pieces that are required. Moreover, the costs of repair and services provided to the rental provider help them to get overall coverage of the same.

Type of flexibility

Depending on the flexibility that the hospital receives from the medical equipment dealer, they generally take the decision. If the rental services are more flexible, then the same is used instead of buying the equipment. The flexibility that the care facilities receive when they take the equipment on rent is more compared to the purchase decision. They can save money and use the same for administering more medical treatments.

Type of patient care

The decision to purchase or rent the equipment depends on the type of patient care that the medical facility is about to provide. If customised patient care is the need of the hour, then buying equipment is not wise as you would need to change the same frequently. On the contrary, in such situations renting is a better option. You can get patient-friendly equipment now and then.


To sum up, the decision to rent or purchase medical equipment depends on many factors. For buying good quality medical equipment pieces, approach KR Lynch. We are a trusted name dealing in medical and surgical equipment. To know more, check our website.
