What are the Basic Functions of Breathing Circuits?

Author: admin / 2022-10-21

Ventilators can increase lung ventilation and reduce the consumption of respiratory work. Ventilators for treatment are often used for patients with complicated and severe conditions. It needs more complete functions, and can carry out a variety of breathing patterns to meet the needs of disease changes. Is Disposable Breathing Circuits suitable for all ventilators?


The ventilator must have four basic functions, namely, inflating to the lung, inhaling to exhaling, expelling alveolar gas, and changing from exhaling to inhaling, as well as rotating circulation. It can produce certain respiratory rhythm, including respiratory rate and respiratory rate, and replace the function of respiratory rhythm controlled by the human respiratory central nervous system; Provide appropriate tidal volume (VT) or minute ventilation (MV) to meet the needs of respiratory metabolism. The air supply replaces the human nose function with heating and humidification, which can provide more O2 than the atmospheric oxygen content, thus increasing the inhaled O2 concentration and improving oxygenation.


Disposable Breathing Circuits is applicable to all ventilators. Indications of Disposable Breathing Circuits include acute respiratory failure caused by various reasons, including acute exacerbation of chronic respiratory failure caused by respiratory distress syndrome (ARDS); Persistence of severe acute pulmonary edema and asthma; Ventilation support during and after cardiothoracic surgery in children; High frequency ventilation is usually used for fibrobronchoscopy, neck and trachea surgery for patients with respiratory insufficiency.


Disposable Breathing Circuits can prevent cross infection transmitted by body fluids, protect respiratory and anesthetic machines, patients, staff and working environment, reduce hospital infection, reduce the workload and cost of disinfection and cleaning, and protect the interior of the machine from pollution. Reduce nursing hours.
