Frequently asked questions
An Ambu bag (the name comes from the original manufacturer and is now generically used for all manual resuscitators) is a self-inflating bag-valve-mask (BVM) device used for manual ventilation of a patient who is not breathing adequately. It consists of: a self-inflating bag that refills with air automatically after each compression; a non-rebreathing patient valve that allows gas to flow from the bag to the patient during compression and directs exhaled gas out through an exhalation port without re-entering the bag; and a face mask that seals over the patient's nose and mouth. An optional oxygen reservoir bag, when connected to a supplemental oxygen source, enriches the delivered oxygen concentration. The operator holds the mask to the face with one hand (the C-E grip technique), compresses the bag with the other hand, and releases — the bag self-inflates for the next breath. The silicone version uses medical-grade silicone for the bag, valve, and mask components rather than PVC.
Silicone and PVC are both used for manual resuscitator construction, but with different properties relevant to clinical use. Silicone: autoclavable for true sterilisation and reuse; maintains elasticity through repeated sterilisation cycles without cracking or hardening; more durable long-term; transparent or translucent allowing visual inspection; softer compliance provides tactile feedback on bag refill; higher initial cost. PVC: typically lower initial cost; available as single-use disposable format (common in high-resource emergency departments for single patient use); not autoclavable — PVC degrades under autoclave temperatures; acceptable for single use but not for extended reuse with sterilisation cycles between uses. In resource-limited settings and reusable clinical equipment protocols, silicone resuscitators are the more appropriate and cost-effective choice because they can be properly sterilised between patient uses rather than being discarded or inadequately decontaminated.
Bellcross Silicone Ambu Bags are available in three sizes corresponding to standard BVM size classifications: Adult (1600ml self-inflating bag) for adult patients — delivers tidal volumes appropriate for adult lung compliance; Paediatric/Child (500ml bag) for patients approximately 1-8 years or 10-25kg — appropriate for paediatric tidal volumes; Infant/Neonatal (240ml bag) for neonates and infants under 1 year or below 10kg — provides the smaller, more precise tidal volumes required for neonatal resuscitation. Each size is sold with a corresponding face mask sized appropriately for the age group. The adult set typically includes masks in sizes 3, 4, and 5 to accommodate different adult facial dimensions. A paediatric mask (size 2) accompanies the paediatric bag.
Yes. The silicone construction of the Bellcross ambu bag is the key clinical advantage over PVC resuscitators — it can be disassembled and autoclaved (steam sterilised at 121°C at 15 psi for standard cycles) between patient uses. The bag, valve, and mask components can be separated for sterilisation, ensuring complete decontamination rather than relying on surface wipe disinfection which cannot guarantee sterilisation of internal surfaces that come into contact with the patient's exhaled breath. After sterilisation, components are reassembled and stored in a clean, covered location on the emergency trolley or crash cart. The non-rebreathing valve should be checked for correct function after each reassembly by occluding the patient outlet and squeezing the bag — resistance should be felt, confirming valve competence.
Without supplemental oxygen, a self-inflating bag-valve-mask resuscitator delivers ambient air at approximately 21% oxygen concentration — which is sub-optimal for resuscitation but maintains basic ventilation. When a supplemental oxygen supply is connected to the oxygen inlet port at a flow rate of 10-15 litres per minute without an oxygen reservoir bag, delivered oxygen concentration is approximately 40-60%. When the oxygen reservoir bag is attached and oxygen flow is 10-15L/min, the delivered oxygen concentration approaches 90-100% — as the reservoir pre-fills with pure oxygen between breaths, each compression delivers a near-100% oxygen tidal volume. In cardiac arrest and respiratory emergency resuscitation, the target is to deliver 100% oxygen if available, making the reservoir bag an important component for high-quality BVM ventilation.
The C-E (or C and E) grip is the recommended single-operator face mask application technique for bag-valve-mask ventilation. With one hand, the operator forms a 'C' shape with the thumb and index finger, pressing these digits down firmly on the top of the face mask to seal it against the face. The remaining three fingers (index, middle, ring) form an 'E' shape along the patient's mandible (lower jaw), lifting the jaw upward into the mask — this jaw-thrust position maintains airway patency. The other hand compresses the bag with enough volume to produce visible chest rise (approximately 500-600ml for adults — one-third to one-half of the adult bag). In team resuscitation settings, one operator holds the mask with both hands using the two-handed C-E technique for a better seal while the second operator squeezes the bag, improving ventilation quality significantly over single-operator technique.

Airways Surgicals Airomount Catheter Mount
Ventilated patients require a connection between their endotracheal tube and the breathing circuit that does more than simply join two pieces of equipment. That connection must absorb the weight of heavy circuit tubing so it doesn't drag on the ET tube and traumatize the trachea. It needs to provide flexibility for patient repositioning without disconnecting the airway. It should allow suctioning and bronchoscopy access without breaking the circuit seal. Standard rigid connectors fail at all three requirements, which is why tracheal injuries from tube displacement remain a persistent ICU complication. Airways Surgicals Airomount catheter mounts were engineered specifically to solve these mechanical stress points in ventilated patient management. This is a flexible tubular connector designed to link the patient's endotracheal tube or tracheostomy tube to the breathing circuit in anesthesia delivery systems, mechanical ventilators, and resuscitation equipment. The primary function is transferring the weight and drag of the breathing circuit away from the airway device, minimizing traction and torque forces on the ET tube that can cause tracheal mucosal injury, tube migration, or accidental extubation during patient care activities. The double swivel elbow configuration provides rotational freedom at both ends of the mount. This dual-articulation design allows the breathing circuit to be positioned optimally without transmitting rotational forces to the ET tube. Clinical staff can reposition patients, adjust circuit angles, or accommodate surgical field requirements without fighting against rigid connections that want to twist the airway back to their preferred geometry. The collapsible corrugated tubing construction (in corrugated models) provides axial flexibility while maintaining structural integrity under positive and negative pressure. The corrugations allow the tube to extend, compress, and bend without kinking or collapsing, which is critical during patient transport, surgical positioning changes, or when accommodating different patient sizes and bed heights. Smooth bore variants offer lower airflow resistance for patients requiring minimal dead space. The suction port with flip-top cap (when present) enables closed-system suctioning without disconnecting the breathing circuit. This maintains PEEP (positive end-expiratory pressure) during suctioning procedures, prevents alveolar de-recruitment that occurs with open suctioning, and reduces staff exposure to aerosolized pathogens. The tethered cap design ensures the port remains clean when not in use and cannot be misplaced. Standard 15mm ID / 22mm OD connectors ensure universal compatibility. The patient end features a 15mm female connector that fits all standard endotracheal and tracheostomy tubes. The circuit end features a 22mm female / 15mm male connector compatible with all breathing system Y-pieces, HME filters, and ventilator circuits meeting ISO standards. The transparent material allows visual confirmation of condensate accumulation and secretions within the mount, alerting staff when replacement is needed to maintain optimal airflow and prevent infection risks from contaminated equipment. Individual sterile packaging ensures infection control compliance for single-patient use, which is now standard practice in most facilities to prevent ventilator-associated pneumonia and cross-contamination. For distributors supplying intensive care units, operating rooms, anesthesia departments, and respiratory therapy services, catheter mounts represent essential respiratory consumables with predictable usage tied to ventilated patient census.

Airways Surgicals Airopop CPAP Nasal Mask
Sleep apnea therapy fails for most patients not because the machine delivers inadequate pressure. Not because the prescription was wrong. It fails because the mask is uncomfortable enough that patients find reasons not to wear it every night. Pressure points on the nasal bridge by 2 AM. Strap marks still visible at breakfast. Air leaks every time you shift position. These are the small frustrations that accumulate until the expensive CPAP machine gathering dust in the closet becomes just another abandoned medical device that technically works but nobody actually uses. Airways Surgicals Airopop nasal mask was designed to address the comfort barriers that undermine CPAP therapy compliance. This is a lightweight nasal interface mask designed for continuous positive airway pressure (CPAP) therapy in patients diagnosed with obstructive sleep apnea (OSA). The mask covers only the nose, delivering pressurized air through soft silicone cushions that create a seal around the nasal area while leaving the mouth free and unobstructed. This minimalist design is preferred by nasal breathers who find full-face masks claustrophobic and prefer less facial coverage during sleep. The soft silicone nasal cushion features a dual-wall construction that conforms to individual facial contours without requiring excessive strap tension. This cushion technology distributes seal pressure evenly across the contact surface rather than concentrating force on pressure points like the nasal bridge, which is the primary complaint causing mask abandonment. The cushion is available in multiple sizes (Small, Medium, Large) because proper sizing is critical for both comfort and seal effectiveness. An incorrectly sized cushion either leaks or requires overtightening to maintain seal. The adjustable four-point headgear system uses soft elastic straps with Velcro adjustment that allows independent tuning of upper and lower strap tension. This granular adjustability accommodates different head shapes and sizes while maintaining stable mask position throughout the night despite sleep position changes. The quick-release clips allow mask removal without readjusting straps, which is valuable for middle-of-night bathroom breaks or when briefly removing the mask is necessary. The lightweight frame minimizes the sensation of wearing equipment on your face. Heavier masks create fatigue and pressure awareness that interferes with sleep initiation. The rigid frame component maintains cushion shape and position while the minimal design reduces overall weight to barely noticeable levels once patients acclimate. The swivel elbow connection at the frame allows tubing rotation without torquing the mask seal. This feature accommodates different sleeping positions and tubing routing preferences without generating the twisting forces that break seal integrity and cause leaks. Active sleepers who change position frequently benefit considerably from this rotational freedom. The exhalation port features diffuser technology that disperses exhaled air quietly to minimize disturbance to bed partners. Early CPAP masks were notoriously loud, creating enough air turbulence noise to wake anyone sleeping nearby. Modern diffuser design redirects exhaled air in a pattern that reduces noise while maintaining proper CO2 washout. For distributors supplying sleep medicine clinics, home medical equipment providers, and respiratory therapy departments, nasal CPAP masks represent essential durable medical equipment with replacement cycles driven by cushion wear.

Airways Surgicals Airoventuri Venturi Mask
Oxygen therapy for COPD patients operates under a paradox that standard oxygen delivery systems cannot accommodate. Give too much oxygen and you risk suppressing the hypoxic respiratory drive that keeps these patients breathing. Give too little and hypoxemia worsens. Simple masks and nasal cannulas offer no precision here, just rough approximations that force clinicians to titrate blindly and hope physiological monitoring catches problems before they become crises. The margin between therapeutic and harmful oxygen concentration can be as narrow as five percentage points. Venturi masks solve this control problem through engineering that standard oxygen delivery devices ignore entirely. This is a high-flow oxygen delivery system designed to provide precise, controlled oxygen concentrations (FiO2) ranging from 24% to 60% regardless of patient breathing pattern variations. The mask uses air-entrainment technology based on the Venturi principle, where high-velocity oxygen flow through a narrow jet creates negative pressure that entrains room air at a fixed ratio, diluting pure oxygen to predetermined concentrations. This principle-based dilution ensures consistent FiO2 delivery even when tidal volumes, respiratory rates, or inspiratory flow demands fluctuate. The color-coded diluters are where precision lives in this system. Each diluter is engineered with specific port geometry that determines the air-to-oxygen mixing ratio. Blue delivers 24% oxygen at 2-4 L/min flow. Yellow delivers 28% at 4-6 L/min. White delivers 31%. Green delivers 35%. Pink delivers 40% at 8-10 L/min. Orange delivers 50%, and some kits include red for 60% at 10-12 L/min. The color coding prevents selection errors during emergency situations where grabbing the correct diluter must happen instantly without consulting reference charts. The high-flow characteristic matters clinically because total flow (oxygen plus entrained air) meets or exceeds patient inspiratory flow demand. Low-flow devices like nasal cannulas deliver oxygen at 1-6 L/min, but patients can inhale at 30-40 L/min during respiratory distress. The gap gets filled by room air (21% oxygen) diluting whatever the cannula delivers. Venturi systems provide total flows of 30-60 L/min depending on diluter selection, eliminating room air dilution and maintaining precise FiO2. The transparent PVC mask construction allows visual monitoring of facial color, lip position, and secretions without removing the mask. The soft, anatomically-molded design with cushioned edges minimizes pressure points during extended use. The adjustable nose clip and elastic headstrap provide secure positioning without excessive tightness. The elongated style extends under the chin, improving seal without claustrophobic full-face coverage. The 7-foot oxygen supply tubing is crush-resistant with star lumen design that maintains patency even when kinked or compressed. This length provides mobility for patient repositioning without disconnecting oxygen supply. Barbed fittings at connections prevent accidental disconnection during use. Venturi masks are preferred in COPD exacerbations, post-operative recovery requiring controlled oxygenation, pneumonia with hypoxemia risk, and any condition where oxygen toxicity or CO2 retention are clinical concerns. The device is latex-free, single-use disposable, and individually packaged. For distributors supplying respiratory therapy departments, emergency rooms, intensive care units, and home oxygen providers, Venturi masks represent essential controlled oxygen delivery devices.
