Ventilator

A ventilator is an important mechanical ventilation device that replaces or assists people's breathing. Ventilators play an important role in the treatment and rescue of patients with respiratory failure, anesthesia respiratory management during surgery, respiratory support therapy for chronic respiratory diseases (such as chronic obstructive pulmonary disease), and respiratory support during emergency resuscitation,The following are its characteristics and uses: 

Characteristic:

Multiple gas supply driving modes: ventilators have three types of gas supply driving modes: pneumatic, electric, and pneumatic electronic control. Among them, the pneumatic type uses compressed gas supply; The electric type uses electric gas supply; The pneumatic and electronic control type uses compressed gas and electric supply to meet different clinical needs and usage scenarios.

Equipped with humidification device:

A necessary humidifier for modern ventilators, usually installed in the inhalation circuit, can heat and humidify the inhaled gas, simulate the functions of the human nasal cavity and oral cavity, prevent dryness of the respiratory mucosa, and maintain the normal function of the respiratory mucociliary system. Common types include heating humidification, nebulization humidification, etc.

Accurate air oxygen mixing:

The air oxygen mixer can adjust the compressed oxygen and air in proportion to the safe oxygen concentration required for treatment and output it to the patient. It uses the jet principle or electromagnetic proportional valve to accurately control the oxygen concentration, and also has monitoring and alarm functions for output oxygen pressure, flow rate, and oxygen concentration, ensuring accurate and controllable oxygen concentration for patients.

Rich attachments:

Breathing valves, safety valves, steam traps, flow and pressure sensors, one-way valves, filters, gas storage bags, and various classification methods can be used to classify portable emergency ventilators, respiratory therapy ventilators, anesthesia ventilators, and home ventilators; Divided into infant/newborn specific ventilators, child/adult ventilators, and adult ventilators according to their intended use; According to the driving mode, it can be divided into pneumatic controlled ventilators, pneumatic electronically controlled ventilators, and electrically controlled ventilators; According to the connection method with the patient, it can be divided into invasive ventilators and non-invasive ventilators. Equipped with a monitoring and alarm system, the modern ventilator host's monitoring and alarm system can display real-time respiratory parameter values, the current status of the ventilator, and parameter adjustment status. When the error exceeds a certain range, an alarm is triggered, and the ventilator is ensured to be within a safe range through safety valves and other devices. 

Usage:

Providing oxygen support:

For patients with severe hypoxia, such as acute respiratory distress syndrome and chronic obstructive pulmonary disease, high concentration oxygen is provided to rapidly improve blood oxygen saturation and maintain normal function of various tissues in the body; By increasing the concentration of inhaled oxygen, increasing the oxygen content in the alveoli, promoting the diffusion of oxygen into the blood, and correcting hypoxemia.

Implementing mechanical ventilation:

In intensive care and emergency situations, for patients with insufficient or failed spontaneous breathing, such as severe pneumonia, respiratory failure, and multiple organ failure, ventilators can replace spontaneous breathing by setting respiratory rate and tidal volume to ensure effective gas exchange.

Adjusting respiratory parameters:

Adjust respiratory frequency, pressure, and other parameters according to the patient's condition to meet the physiological needs of different patients such as airway obstruction, changes in lung compliance, and insufficient respiratory drive, reduce pathological respiratory burden, prevent lung injury, and improve ventilation efficiency.

Sputum aspiration to maintain airway patency:

patients, negative pressure is used to aspirate respiratory secretions to prevent airway obstruction, reduce the risk of ventilation and oxygenation being affected and infection, and prevent complications.

Monitoring respiratory status:

Through various sensors and monitoring devices, real-time monitoring of parameters such as respiratory rate, tidal volume, airway pressure, oxygen saturation, etc. The data can be displayed on the built-in display screen or remotely monitored by the central monitoring system, helping doctors to timely grasp the patient's respiratory status and adjust treatment plans.
