Breathing Bag by KELLYUNION: Essential Respiratory Support for Critical Care


A Breathing Bag, also known as a manual resuscitation bag or Ambu bag, is a fundamental, life-sustaining device used to provide positive pressure ventilation to patients who are not breathing or are breathing inadequately. This essential piece of equipment is a cornerstone of emergency response, anesthesia administration, and patient transport. The primary purpose of a Breathing Bag is to deliver ambient air or supplemental oxygen directly into a patient's lungs, ensuring vital gas exchange until spontaneous breathing resumes or mechanical ventilation is established. The reliability and performance of the Breathing Bag are therefore non-negotiable in high-stakes medical environments.


Core Knowledge: Understanding the Breathing Bag

The standard Breathing Bag is a hand-held, self-inflating device comprised of several key components: the bag itself, a patient valve, an oxygen reservoir, and a face mask. Its operation is based on manual compression; when squeezed, the bag forces air through a one-way valve to the patient. Upon release, the Breathing Bag automatically re-inflates, drawing in ambient air or oxygen while the patient valve allows for exhalation. The simplicity of this design is its greatest strength, allowing for immediate use without an external power source. A high-quality Breathing Bag must maintain integrity under repeated use, offer consistent volume delivery, and provide a secure, leak-free connection system.


Primary Applications: Where the Breathing Bag is Indispensable

The versatility of the Breathing Bag makes it critical across numerous healthcare settings. Its most prominent use is in Emergency Medical Services (EMS) and Cardiopulmonary Resuscitation (CPR), where it is the first-line tool for ventilating patients in cardiac arrest or respiratory failure. Within hospital walls, the Breathing Bag is vital in Operating Rooms and Post-Anesthesia Care Units (PACU) for managing patient airways during induction, emergence, or in case of ventilator malfunction. Furthermore, it is indispensable during patient transport within a facility (e.g., to radiology) or between facilities, providing continuous ventilation support. Finally, these bags are essential stock in hospital wards, ICU, and emergency departments for rapid response to acute respiratory distress.


Introducing the KELLYUNION Breathing Bag: Engineered for Reliability

The KELLYUNION Breathing Bag is meticulously engineered to meet the rigorous demands of these critical applications. We understand that in moments of crisis, every detail counts. Our Breathing Bag is designed to provide healthcare professionals with a dependable, intuitive, and high-performance tool they can trust implicitly during ventilation procedures.


Precision Capacity Options for Tailored Care

Recognizing that patient needs vary, the KELLYUNION Breathing Bag is available in multiple capacity sizes to ensure appropriate tidal volume delivery. Our range includes 23L, 18L, 16L, and 12L options. This selection allows medical personnel to choose the ideal Breathing Bag for different patient populations, from adults to pediatric cases, ensuring more controlled and effective ventilation support.


Optimized Chamber Design for Effective Ventilation

The chamber dimensions of our Breathing Bag are precisely crafted to facilitate optimal hand placement and efficient compression. For our high-capacity units, the 23L Breathing Bag features a chamber size of 245x150mm, while the 18L Breathing Bag measures 245x350mm. This ergonomic design ensures that the Breathing Bag fits securely in the hand, allowing for consistent and fatigue-resistant squeezes to deliver the necessary air volume repeatedly.


Superior Material and Sensory Profile

The tactile and olfactory experience of a Breathing Bag matters. Cheap materials can off-gas and create a pungent smell, causing discomfort or distraction. The KELLYUNION Breathing Bag is manufactured from premium medical-grade materials that guarantee no pungent smell. It features a soft handle for a secure, comfortable grip and a smooth touching surface, enhancing the user experience during prolonged resuscitation efforts.


Standardized Connector and Impeccable Construction

Interoperability is key. Our Breathing Bag comes equipped with a 22mm standard connector, ensuring universal compatibility with most face masks, endotracheal tubes, and other airway adjuncts. The construction integrity of the Breathing Bag is paramount. We employ advanced manufacturing techniques to create a product with a net and smooth surface, which is free from pinholes and dirt. This flawless construction prevents air leaks, maintains hygiene standards, and upholds the overall durability of the Breathing Bag.
