Department of Critical Care Medicine develops closed sputum suction technology

Many patients require mechanical ventilation treatment immediately after admission to the ICU, and sputum suctioning is the most frequent operation for mechanically ventilated patients in the ICU. The traditional open suction method requires the suction catheter to be separated from the ventilator during each suction process, interrupting mechanical ventilation and the patient's access to the air, which generate the great risks.

In response to this situation, the Intensive Care Unit (ICU) of Zhongshan People's Hospital actively developed closed sputum suction technology to fill the technical gap in our hospital and bring good news to patients.

The closed suction catheter does not need to terminate mechanical ventilation, and the airway pressure is not affected to reduce accidents. It has important clinical significance for patients with respiratory diseases. Compared with the open suction tube, the closed suction set makes a complete seal. It protects the safety of patients and medical staff, prevents droplet-borne diseases, and reduces unnecessary nosocomial infections.

Airway humidification can be sustained during mechanical ventilation. The closed suction can use a micropump to continuously pump physiological saline through the injection port to reduce the viscosity of sputum and reduce the incidence of sputum blocking the artificial airway during mechanical ventilation.

The closed suction system is simple and convenient to operate and does not require disconnecting the ventilator. It can ensure ideal oxygenation during the sputum suction process and prevent reflex symptoms such as increased heart rate and blood pressure and reduces the risk of sputum suction in awake patients. sense of fear. The use of closed suction technology can significantly reduce the incidence of hypoxemia and bradycardia, shorten the time required for various physiological indicators to return to the level before sputum suction, and enhance the safety of medical treatment for patients.
