For hospital teams responsible for procuring materials for the hemodialysis department, choosing the right dialysis supplies is an important yet often challenging task. Their core objective is to find products that are safe, reliable, stable in supply, and reasonably priced. However, in actual operation, this process involves many real-world difficulties.

In the anesthesia system, the anesthesia breathing circuit is the crucial channel connecting the patient to the anesthesia machine. It not only delivers oxygen and anesthetic gases and removes exhaled carbon dioxide, but also plays multiple roles in heat and moisture retention, resistance control, and gas mixing regulation. The proper selection of a circuit directly affects the safety, efficiency, and cost of anesthesia, as well as a hospital’s sustainability goals.

In the core environment of operating rooms and anesthesia management, the anesthesia breathing circuit plays a vital role in sustaining life, ensuring the effective delivery and exchange of oxygen and anesthetic gases during surgery. As a crucial component of this sophisticated system, the breathing bag—also referred to as the reservoir bag, rebreathing bag, or anesthesia bag—is far more than a simple accessory. Its design, material, and performance selection are matters of serious technical significance. The proper selection of a breathing bag profoundly impacts several key aspects: it directly relates to the patient’s essential safety assurance, the operational reliability of the equipment, and the overall cost-effectiveness of long-term use. Furthermore, the choice of material is closely associated with minimizing potential risks of cross-contamination and addressing patient-specific allergic sensitivities.

This seemingly basic airway tool truly embodies both the starting point of responsibility and the meaning of defense. Its performance — sealing reliability, tactile comfort, and breathing support efficiency — has become an increasingly vital component in ensuring clinical safety. A deep understanding of its clinical applications, along with the accurate identification and selection of high-performance masks, is a fundamental obligation for every medical institution entrusted with patient safety.

In airway management, the laryngeal mask airway (LMA airway) occupies an indispensable role, especially when endotracheal intubation is either not applicable or encounters significant obstacles. Whether used as a supportive tool for spontaneous breathing or as an adjunct for positive-pressure ventilation, the laryngeal airway demonstrates remarkable adaptability. Its applications extend from meticulously planned operating room environments to pre-hospital and in-hospital emergency rescue scenarios.
