A mechanical ventilator which is also known as ventilator or respirator is a life support device. It helps a patient to breathe when they are unable to breathe on their own. It also helps patient to breathe when they are recovering from any critical illness or surgery. A patient is connected to the ventilator with the help of a hollow tube which is removed when the patient starts breathing normally on their own.
A mechanical ventilator is used for the following:
The following are the common indications of mechanical ventilation:
A ventilator is connected to a patient with the help of a tube called endotracheal tube (ET) which is inserted through nose or mouth and pushed down into the windpipe (trachea). The process of inserting the ET tube into patient’s windpipe is called as intubation. In some patients, a surgery is performed to make a hole in the neck through which the tube that is connected to the ventilator is inserted. This surgery is referred to as tracheostomy. The ventilator delivers air to the patient though the tubes. The ventilator may completely control breathing when a patient is unable to breathe at all. In other cases, in which the patient’s breathing is impaired, the ventilator assists in breathing. The respiratory secretions tend to get settled on the ventilator tubes which need to be removed regularly to prevent obstruction and infection of the airways. These secretions are removed through suction.
The team of healthcare professionals who care for the patients on mechanical ventilation include- anesthesiologist, pulmonologists, critical care physicians, critical care nurses and respiratory therapists.
Patients on the ventilator are also connected to a monitor which measures the patient’s heart rate, blood pressure, and oxygen saturation. Other tests for assessing the health of a patient on mechanical ventilator may include chest x-rays and measurement of blood gases. The healthcare team uses this information to assess the health condition of the patient and may adjust the settings of the ventilator if required.
A mechanical ventilator may be lifesaving, but it also has its risks. The following conditions may occur while a patientis on a mechanical ventilator:
Mechanical ventilation does not heal the patient instead it allows the patient to maintain normal blood gas levels (oxygen and carbon dioxide) unless the patient’s condition is stabilised. The following are the main benefits of the mechanical ventilation:
The main aim of using a mechanical ventilator is to maintain respiratory function of the patient until his/her health is stable. The healthcare team performs a series of tests to check the patient’s ability to breathe on their own. The mechanical ventilator can be removed as soon as a patient resumes normal breathing.
