Pulmodyne O2-MAX Disposable CPAP System for EMS and Hospital Use

Choose Your O2-MAX System:

Each part number is a case of 10 complete systems: generator with inhalation filter, 72 in circuit, PEEP valve, BiTrac ED mask with headgear and O2-MAX Guard exhalation filter.¹² N adds the nebulizer, -1 adds a pre-attached Ohmeda Quik-Connect, and X is the expandable circuit.² Shop opens the system page. Quote sends the part number to Pacific Biomedical customer service.

Which fitting do I need? Every O2-MAX needs a 50 psi oxygen source, not a flowmeter.¹

• Ohmeda wall outlet: choose a -1 part number. The Ohmeda Quik-Connect comes attached.²
• Cylinder regulator with a 50 psi DISS outlet: choose a part number without -1: 313-7538X, 313-7555X or 313-7556X, or with a nebulizer 313-7554XN, 313-7555XN, 313-7556XN or 313-7557XN by quote.²⁴
• Chemetron, Puritan Bennett or Schrader wall outlet: choose a part number without -1 and add the matching Quik-Connect: 313-121111, 313-131111 or 313-141111 (by quote).⁵

O2-MAX Trio Systems:

Trio systems add a knob that sets about 30, 60 or 90%+ FiO2. They come with an expandable circuit, with or without the nebulizer.⁶² The Trio control unit, part number 313-8000, converts a Fixed generator to a Trio, and cannot be used alone.⁷⁸² All Trio part numbers are by quote.

Product Highlights:

• High flow from a 50 psi source. The venturi generator connects directly to a 50 psi oxygen source and entrains room air to deliver up to 140 LPM at about 30% FiO2. The PEEP valves maintain positive pressure at flows from 60 to 140 LPM.¹
• PEEP set by the valve, not the flowmeter. 3-SET (5, 7.5, 10), 5-SET (5 to 15) or fixed valves (2.5 to 20 cmH2O) hold PEEP independent of the patient's flow rate.⁹²¹
• Filtered in and out. An inhalation filter on the generator and the pre-attached O2-MAX Guard exhalation filter. Filter efficiency is more than 99.99% bacterial and viral.²³
• Nebulize during CPAP. N systems include a nebulizer canister that pushes into the nebulizer port with a quarter turn. The filter sits before the nebulizer port, so it saturates with medication less than an in-line filter would, and flow to the patient stays consistent.¹³²
• Up to 28 minutes on a D cylinder (Fixed system), or run it from the vehicle or hospital wall outlet.²⁵
• Select 30, 60 or 90% FiO2 with Trio. Trio systems, or a Fixed generator fitted with the Trio control unit (313-8000), set about 30, 60 or 90%+ FiO2 with a knob.⁶⁸⁷
• Ready to apply. No assembly. The BiTrac ED mask comes with pre-attached headgear and the adjustable Omni Clip, on a 72 in anti-asphyxia circuit with expandable tubing. Check airflow and valve function before use.¹⁹²¹⁰
• Quik-Connect ready. -1 systems come with a disposable Ohmeda Quik-Connect that plugs into an Ohmeda wall outlet and moves with the patient from bedside to ambulance.²⁵⁹

Works With:

PEEP Valves and Colors:

O2-CPAP valves snap onto the end of the O2-MAX circuit and maintain positive pressure at flows from 60 to 140 LPM.¹ Swap a valve to change PEEP, or replace a valve that becomes occluded.¹¹² Each valve part number is a case of 10.¹³ The standalone O2-MAX Guard exhalation filter is part number 313-8300 (Quote).³

O2-MAX vs Flow-Set Disposable CPAP:

Disposable EMS CPAP comes in two common designs. A flow-set CPAP uses the oxygen flowmeter as the pressure control: more oxygen flow, more PEEP, checked on a manometer. The O2-MAX separates the two: a 50 psi oxygen source drives a high-flow venturi, and the valve on the circuit sets PEEP.¹⁹ The table compares the O2-MAX with a flow-set disposable CPAP that has a built-in color-coded manometer and an integrated-nebulizer version. Flow-set values come from that design's published flow-to-PEEP chart and instructions.

Need a CPAP that runs from a flowmeter? Pulmodyne's GO-PAP disposable emergency CPAP runs on a fixed 10 LPM from a metered oxygen supply, about 40 minutes per D cylinder, with PEEP set at 5, 7.5 or 10 cmH2O on the generator.¹⁵

Replacing a flow-set disposable CPAP? Check the oxygen supply first: the O2-MAX connects to a 50 psi outlet, not a flowmeter, and PEEP moves from the flowmeter to the valve, so crews choose a valve setting instead of reading a flow-to-PEEP chart.¹⁹

Who Uses This:

• EMS Agencies and Fire Departments: high flow for severe respiratory distress,¹¹¹ PEEP chosen with the valve, nebulizer systems for in-line treatments, and filtered exhalation in the patient compartment.²³ Compare all disposable EMS CPAP devices.
• EMTs, Paramedics and BLS Crews: PEEP is a valve setting rather than a flow calculation,⁹ for agencies whose scope and protocols include CPAP at the EMT, AEMT or paramedic level.¹⁶
• Emergency Departments and Hospitals: labeled for hospital as well as prehospital use. The Quik-Connect plugs into the wall outlet and moves with the patient between rooms and to the ambulance.¹⁵
• Critical Care and Interfacility Transport: Trio systems set about 30, 60 or 90%+ FiO2 for patients who need more oxygen, with continuous pulse oximetry.⁶
