    What is Ventilator

    A medical ventilator (or simply ventilator in context) is a mechanical ventilator, a machine designed to move breathable air into and out of the lungs, to provide breathing for a patient who is physically unable to breathe, or breathing insufficiently. Ventilation: is using artificial methods to assist breathing
    Respiration: transporting oxygen and carbon dioxide between cells and the external environment.

    Ventilation Parameters

    Respiratory Rate:Respiration rate is at which breaths occur, usually measured in breaths per minute. The typical respiratory rate for a healthy adult at rest is 12–20 breaths per minute. Over 35 breaths per minute is a sign of unsufficient ventilation
    Tidal volume: During Ventilator respiration, total gas volume enters to or exits from lungs.
    Tidal capacity: Maximum volume that lungs can handle.
    Alveolar Ventilation: Total Gas exchange amount in a minute.
    Peak Expiratory Flow Rate: is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways.

    Ventilation Pressure Types

    Negative Pressure Ventilator: that enables a person to breathe when normal muscle control has been lost or the work of breathing exceeds the person's ability. The negative form of pressure ventilation has been almost entirely superseded by positive pressure ventilation or biphasic cuirass ventilation.
    Positive Pressure Ventilator: Positive-pressure ventilators increase the patient's airway pressure through an endotracheal or tracheostomy tube. The positive pressure allows air to flow into the airway until the ventilator breath is terminated. Then, the airway pressure drops to zero, and the elastic recoil of the chest wall and lungs push the tidal volume through passive exhalation.

    Working Principle of Ventilator

    During the piston withdrawal period, the ambient air is let in. The ambient air is mixed with O2. The pressure in the regulator is balanced. The air pressure transducer entering the O2 regulator converts it to electrical energy and sends it electronically for control. Oxygen combines in the air mixer manifold. The flow is then transmitted through the oxygen solenoid to the air channel. When these operations are performed, the piston returns to its original position, again with air from the medium.
    Piston: The cylinder system is a system that allows air to be drawn from the medium to provide oxygen and air mixture.
    Optical key: The light sensor detects two falling lights, two at the beginning and one at the end. When the piston is in the first position, the light falls on the switch at the beginning, while the light does not fall on the switch at the beginning. The key that perceives this state decides how the motor will move by sending information to the electronic system.
    Piston gears for motor: To transfer motor movements to the pistons, both the motor and the gear on the piston are needed. If the engine has a circular gear, it is a straight gear system. The spur gear converts the circular motions it receives into forward or backward motion.
    Engine Encoder: This allows the engine piston to move back and forth, which is controlled by the engine drive circuit. The motor encoder circuit is located at the top of the motor and detects the direction and speed of an optical drive motor during motor rotation and sends this data to the electronic drive.
    Oxygen sensor Measures the percentage of oxygen pumped from the cylinder, the oxygen in the delivered gas produces a voltage depending on the partial pressure. Oxygen sensor has ± 3% detection sensitivity.
    System operatio Two optical switches on the piston control the position of the piston and send it to the electronic system. The electronic system sends the motor a notification to the motor for the direction of rotation. The engine transfers the movement to the pistol through gear systems. When the piston is withdrawn to get air, the inlet valves are opened. Meanwhile, the pressure inside the cylinder is analyzed by transducer. The output piston is opened and the air is inspired monofold.

    Ventilation Types

    2 types according to occured in chest (positive, negative), 2 types according to patient connection (noninvasive ventilation, invasive ventilation), Ventilation modes according to inspiratory flow start mode: The inspiration is triggered when the ventilator starts. The volume or pressure controls. In the second type, when the patient initiates inspiration, the patient develops triggered ventilation. Either assisted ventilation or synchronized intermittent forced ventilation or pressure assisted ventilation occurs. Ventilation modes according to the target of the inspiratory current: Volume-targeted, volume-constant
    Passing from inspiration to exhalation: These can be both pressure and volume controlled.

    Patient Respiration System in Ventilators

    Connects patient to ventilator gas output. It also transfers patients exhalation to machine.
    The system has an inspiratory filter ventilator, a respiratory cycle collection bottle filter, a humidifier unit and an expiration unit.
    Inspiration filter: Protect the patient and ventilator device system against particles that may be contaminated from the outside. Granules larger than 0.3 min are blocked by this filter.
    Collector Bottle: The nourishment that occurs in the patient's expiration date is swollen.
    Ventilator Device Respiratory Circuit: A ventilator that provides gas flow between the device and the patient. Humidifier Unit: It is the unit that provides the humidification of the air given to the patient.
    Output Filter: Prevents airborne particles from interfering with the system.

    Warnings about Ventilator

    Before using, ventilator must be tested
