Ventilator
(Redirected from Medical ventilator)
Ventilator[edit | edit source]
A ventilator is a machine designed to provide mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Modern ventilators are computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask.
History[edit | edit source]
The history of ventilators dates back to the 19th century with the development of the first mechanical ventilators. The East-Radcliffe Respirator was one of the early models used in hospitals. Over the years, technology has advanced significantly, leading to the development of sophisticated devices like the Hamilton C6.
Types of Ventilators[edit | edit source]
Ventilators can be classified into several types based on their operation and application:
- Closed-circuit ventilators: These systems are designed to provide a controlled environment for the patient, minimizing the risk of infection and contamination.
- Open-circuit ventilators: These are typically used in less controlled environments and may be more susceptible to external factors.
Functionality[edit | edit source]
Ventilators work by delivering a set volume of air to the patient at a controlled rate. The main parameters that can be adjusted include:
- Tidal volume: The amount of air delivered to the lungs with each breath.
- Respiratory rate: The number of breaths delivered per minute.
- Inspiratory pressure: The pressure applied to deliver the air into the lungs.
Applications[edit | edit source]
Ventilators are used in various medical settings, including:
- Intensive care units (ICUs): For patients with severe respiratory conditions.
- Operating rooms: To assist patients under anesthesia.
- Emergency medicine: For immediate respiratory support in critical situations.
Recent Developments[edit | edit source]
In response to the COVID-19 pandemic, there has been a surge in the development and production of ventilators. Notably, NASA developed the VITAL ventilator, a device specifically designed to address the needs of COVID-19 patients.
