Artificial Respiratory Support Ventilators are professional medical devices that play a pivotal role in critical care and emergency medicine. These life-saving machines are designed to help patients in breathing when their own respiratory systems are compromised, either due to severe illness, injury, or surgery. Ventilators are equipped with advanced technology that precisely provides oxygen and regulates airflow into the patient’s lungs, maintaining proper oxygenation and carbon dioxide removal. They are crucial in intensive care units, emergency rooms, and operating rooms, as they provide essential support for patients with conditions such as acute respiratory distress syndrome (ARDS), pneumonia, chronic obstructive pulmonary disease (COPD), and those undergoing critical surgeries. Ventilators come in different modes and settings to cater to the specific needs of individual patients, allowing healthcare professionals to individualise ventilation strategies based on factors like age, lung capacity, and the underlying cause of respiratory failure. Continuous monitoring and adjustment ensure the patient receives the appropriate amount of oxygen and maintains a proper breathing rate. The adaptability of ventilators also allows for the weaning process, gradually reducing support as the patient’s condition improves, ultimately facilitating a safe transition back to natural breathing.
