Frequently asked questions
A catheter mount (also called breathing circuit connector or tube extension) is a flexible tubular device that connects the patient's endotracheal tube or tracheostomy tube to the breathing circuit in ventilators or anesthesia systems. Its primary purpose is to transfer the weight and drag of the heavy breathing circuit tubing away from the ET tube, minimizing traction and torque forces that can cause tracheal trauma, tube migration, or accidental extubation. The flexible, often corrugated tubing provides mobility and flexibility, allowing patient repositioning without disrupting the airway connection.
Double swivel refers to rotating elbow connectors at both ends of the catheter mount (patient end and circuit end). This dual-articulation design allows the breathing circuit to be positioned and oriented in any direction without transmitting rotational forces to the endotracheal tube. Single swivel mounts have rotation at only one end, while fixed mounts have no rotation. Double swivel provides maximum flexibility for patient repositioning, surgical field accommodation, and circuit management without putting torsional stress on the airway that could cause tube displacement or tracheal injury.
Corrugated catheter mounts have accordion-style ridges that provide flexibility and allow extension/compression while maintaining structural integrity against kinking. Expandable catheter mounts can be stretched to different lengths and hold that position (shape memory), useful when exact positioning is needed. Smoothbore catheter mounts have smooth inner walls that reduce airflow resistance and dead space, preferred for pediatric patients or when minimizing breathing work is critical. Corrugated is most common for general use, smoothbore for low-resistance applications, and expandable for precise length adjustment.
Catheter mounts use ISO standard connector sizes: 15mm ID (inner diameter) / 22mm OD (outer diameter). The patient end typically has a 15mm female connector that fits standard endotracheal tubes, tracheostomy tubes, and laryngeal masks. The circuit end has a 22mm female connector (sometimes with integrated 15mm male) that fits breathing system Y-pieces, HME filters, and ventilator circuits. These standardized dimensions ensure universal compatibility across all manufacturers' respiratory equipment meeting ISO 5356 standards.
The suction port (typically with flip-top cap) allows closed-system suctioning without disconnecting the breathing circuit. This is critical for maintaining PEEP (positive end-expiratory pressure) during suctioning procedures, which prevents alveolar de-recruitment and maintains oxygenation. Closed suctioning also reduces staff exposure to aerosolized pathogens from the patient's airway. Some advanced ports have dual-cap designs that allow fiber optic bronchoscopy while maintaining circuit pressure. Not all mounts include suction ports—the choice depends on clinical requirements and institutional protocols.
Catheter mounts are designed and intended as single-use, single-patient disposable devices. They must NOT be reused or resterilized. Each patient must receive a new sterile catheter mount. Reusing these devices introduces unacceptable infection control risks including ventilator-associated pneumonia (VAP), cross-contamination between patients, biofilm accumulation in corrugations that cannot be adequately cleaned, and material degradation that compromises structural integrity potentially leading to disconnection or kinking. Proper disposal as biohazard waste after single use is mandatory.

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.

Airways Surgicals Resuscitator Ambu Bag (BVM Manual Resuscitator)
Emergency ventilation during cardiac arrest or respiratory failure comes down to a manual skill that nobody practices enough until the moment they desperately need it. Squeeze too hard and you rupture alveoli or fill the stomach with air, triggering aspiration. Squeeze too gently and the patient gets inadequate tidal volumes while cerebral hypoxia accumulates by the second. Maintain improper head position and the airway occludes despite perfect bag technique. These are failures that happen in real emergencies when trained providers discover that occasional simulation training does not translate to confident performance under actual code blue pressure. Airways Surgicals resuscitator bags exist because patients in respiratory arrest need immediate positive pressure ventilation regardless of whether trained providers feel confident delivering it. This is a self-inflating manual resuscitator (bag-valve-mask or BVM) designed to provide emergency positive pressure ventilation to patients with absent or inadequate spontaneous breathing during cardiac arrest, respiratory failure, anesthesia induction, and pre-hospital emergency care. The device consists of a self-inflating bag (available in adult 1600ml, pediatric 550ml, or infant 280ml capacities), a non-rebreathing patient valve, a transparent face mask with cushioned seal, and an oxygen reservoir bag that allows delivery of near-100% oxygen when connected to a supplemental oxygen source. The self-inflating bag features an internal spring mechanism that automatically re-expands after manual compression, drawing in ambient air or oxygen from the reservoir for the next breath. This self-inflation characteristic distinguishes these devices from anesthesia bags that require continuous gas flow to remain inflated. The bag can function entirely without electricity or external gas supply, making it suitable for field use where no infrastructure exists. The non-rebreathing valve directs fresh gas flow to the patient during inspiration while venting exhaled CO2 to atmosphere during expiration, preventing rebreathing. The valve design is critical to device performance. Some models use single shutter valves that close the expiratory port during spontaneous inspiration, preventing room air entrainment. Others use duckbill valves with separate expiratory discs. The specific valve design affects oxygen delivery performance, particularly in spontaneously breathing patients. The transparent anatomically-molded face mask with air-cushioned seal provides the interface between device and patient. The cushion compresses to conform to facial contours, creating a seal without excessive pressure. Mask sizing is critical: adult masks fit patients over 88 lbs, pediatric masks fit children 10-50 kg, infant masks fit neonates and small infants. The transparent construction allows visual confirmation of lip color, secretions, and vomit. The oxygen reservoir bag (typically 2600ml for adult systems) attaches to the gas inlet and fills with oxygen when connected to a flow source at 10-15 L/min. With reservoir attached and high oxygen flow, the device can deliver FiO2 approaching 90-100%. Without reservoir, the device delivers approximately 40-50% oxygen even with supplemental flow, as ambient air mixes with oxygen during bag self-inflation. Optional PEEP (positive end-expiratory pressure) valves attach to the exhalation port to maintain positive airway pressure during expiration, which can improve oxygenation in specific clinical situations during resuscitation. These devices are used in crash carts, ambulances, emergency departments, operating rooms, ICUs, and any location where emergency airway management capability is required. Both reusable (autoclavable) and single-use disposable versions exist. For distributors supplying emergency medical services, hospitals, clinics, and first responder organizations, manual resuscitators represent critical life-saving equipment with predictable replacement cycles.
