Non-Rebreather Oxygen Mask (Adult, Elongated Style
This adult-size non-rebreather oxygen mask is a high-flow supplemental oxygen delivery device engineered for emergency and clinical use. It features a built-in one-way exhalation valve and a large reservoir bag to deliver enriched oxygen, supplying roughly 60–90% FiO₂ at recommended flow rates (10–15 L/min). By isolating inhaled oxygen from exhaled CO₂, it maximizes blood oxygenation – far higher than a nasal cannula or simple face mask (which deliver only ~24–50% oxygen. The transparent, latex-free vinyl mask fits over the nose and mouth (elongated style for better coverage) with a soft perimeter seal for comfort. Its adjustable elastic head strap and metal nose clip ensure a secure, custom fit on most adult faces, minimizing leakage and improving oxygen saturation. A 7-foot medical-grade oxygen tubing connects to any standard O₂ cylinder or concentrator (barbed fitting). This single-patient, disposable mask is latex-free (hypoallergenic) and individually packaged to prevent cross-contamination in hospital or field settings.
-
High-Concentration Oxygen Delivery: The reservoir bag accumulates oxygen between breaths, allowing patients to inhale near-pure O₂. At a flow of 10–15 liters per minute, FiO₂ reaches about 60–80% (up to ~90%). (Set flow to at least 10 LPM to keep the bag inflated for maximum effectiveness.) This makes it ideal for raising blood oxygen levels in hypoxemic or critically ill patients.
-
One-Way Exhalation Valve: A precision check valve on the mask directs exhaled air out and blocks room air from entering. This prevents rebreathing CO₂ and guarantees delivery of fresh oxygen each inhale. High inspired oxygen (FiO₂) can be maintained without mechanical ventilation, supporting patients who can still breathe on their own.
-
Adjustable Fit (Head Strap & Nose Clip): The elastic head strap is fully adjustable for a snug, leak-free fit on most adult heads. The metal nose clip can be pinched to contour around the bridge of the nose. Combined with the contoured, elongated mask shape, this helps seal out ambient air and focus oxygen delivery. The mask’s clear, soft vinyl construction allows easy visual monitoring of the patient, and its latex-free material minimizes allergic risk.
-
Reservoir & Tubing: The 750+ mL oxygen reservoir bag (included) stores extra oxygen between breaths, so even deep inhalations draw from enriched reserve oxygen. The kink-resistant 7-foot tubing provides flexibility for patient movement and easy attachment to O₂ sources. (Tubing length and standard fittings ensure compatibility with hospital wall units and portable oxygen tanks alike.)
-
Disposable for Safety: Each polyethylene mask is single-use and individually packaged. This disposable design eliminates cross-contamination between patients, an essential infection-control measure in clinical environments. It is economic yet durable for short-term oxygen therapy.
-
Comfort & Coverage: The elongated mask extends comfortably over the nose and mouth, and a soft foam edge (perimeter seal) cushions contact with the face. The clear, flexible material contours to facial anatomy, fitting even “hard-to-fit” faces with the help of the adjustable strap. This maximizes comfort and helps maintain therapy for as long as needed.
Health Benefits and Clinical Uses
Non-rebreather masks are critical in emergency medicine and respiratory therapy. By delivering high FiO₂ oxygen quickly, this mask helps relieve hypoxemia and improve oxygen saturation in the blood. It is commonly used by EMTs, paramedics, first responders, and in hospitals (ER, ICU, ambulances) for conditions that demand immediate oxygen support. Typical applications include: trauma and shock (e.g. car accidents, severe injury), acute asthmatic attacks, COPD exacerbations, pneumonia, near-drowning, or post-cardiac arrest when breathing is compromised. It’s also indicated for chemical or smoke inhalation, and carbon monoxide poisoning – situations where oxygen competition requires a high-concentration supply. In these scenarios, flooding the lungs with pure oxygen helps drive out carbon monoxide or other toxins from hemoglobin. High oxygen delivery also supports the brain and heart during distress, reducing the risk of organ damage.
Because it does not provide mechanical respiration, the patient must be breathing on their own. However, for any spontaneously-breathing patient needing supplemental oxygen, this mask can quickly raise FiO₂ to hospital-grade levels. The boost in oxygenation can alleviate symptoms like severe shortness of breath and cyanosis. For chronic conditions like advanced COPD or heart failure, it serves as a critical intervention during acute attacks.
Clinicians should ensure proper setup: inflate the reservoir by running oxygen at the required flow (typically 10–15 LPM) before putting on the patient. This guarantees the bag is filled with oxygen. Then fit the mask snugly, and adjust the strap and nose clip to minimize leaks. With this safe setup, the mask can deliver therapeutic oxygen to support patient recovery and comfort.
Overall, this Non-Rebreather Oxygen Mask (Adult, Elongated) is designed to deliver peak performance under stress. Its efficient one-way valve and reservoir system boost inspired oxygen levels for compromised patients. The adjustable, comfortable fit and latex-free construction ensure it can be used safely across diverse clinical scenarios. Whether in an ambulance, emergency department, or hospital ward, this mask is an essential part of respiratory care kits and oxygen therapy protocols.
