1e. How PORTO2VENT™ CPAP

OS

System Works

The System (See figure 1) provides continuous positive airway pressure (CPAP) throughout the breathing cycle
(inspiration and expiration), and flow of gas on patient demand during inspiration.

The peak inspiratory flow rate from the CPAP

OS

unit is determined by the patient inspiratory effort. Prior to inspiration

the flow rate of gas from the CPAP

OS

system is zero liters per minute (lpm) (0 lpm). To initiate flow of gas the patient

must “trigger” the CPAP pressure generator.
DISS Oxygen Inlet Port The gas inlet port is a 9/16 standard DISS oxygen connector. The specification for inlet

pressure is 40 – 60 psi (2.8 – 4.1 bar).
CPAP Pressure Generator The CPAP Pressure Generator maintains a continuous positive airway pressure

and delivers flow from 0 to 100 or greater, liters per minute on demand to a spontaneous breathing patient.
CPAP Adjustment Regulator The CPAP adjustment is an operator adjustable pressure control providing pressure to

the patient airway between 0 and 15 cmH2O.

NOTE: Mask and proximal airway pressure will vary.

Pressure Balanced Patient Valve and Inspiratory Check Valve The inspiratory valve opens to supply flow to a
spontaneous breathing patient during the inspiratory phase of breath delivery. The expiratory valve is pressure
balanced to precisely maintain CPAP levels and reduce patient effort to open and exhale through the valve. The

patient valve gas collector port rotates 360O and is a 22 mm I.D. and 30 mm O.D. port to accept filters and spirometry
devices.

CAUTION: Do not use any other make or manufacturer of the pressure balanced patient valve that is not labeled
for use with the CPAP

OS

device. The patient breathing circuit must be connected as illustrated in section 2c and
described in section 3b of this manual. Failure to do so could result in device malfunction. The patient and
equipment must be observed constantly.

Over Pressure Relief Valve In the event of an occlusion and/or pressure build up in the CPAP

OS

system, the Over

Pressure Relief Valve is preset to relieve pressure at 22 cmH2O.
Anti-asphyxiation Port In the event of complete gas supply failure the Anti-asphyxiation Port allows the

spontaneous breathing patient access to ambient air.
Outlet Port Connector The Outlet Port Connector is a locking bayonet connector used to attach the corrugated

main tube, and engage the airway pressure line.

Airway Pressure Line The Airway Pressure Line is attached from the outlet of the Pressure Balanced Patient Valve
through the outlet connector with a standard 1/8

th

inch I.D. tube.

CAUTION: The airway pressure line is connected internally to the pressure gauge.
Disconnection or occlusion of this line may not be detected. The patient and equipment
must be observed constantly to check for such problems.

Bacteria/Viral Filter The bacteria/viral filter is connected to the Airway Pressure Line and outlet connector.
Corrugated Breathing Tube The corrugated main tube directs gas flow from the CPAP

os

outlet port through the

inspiratory valve to the patient and Pressure Balanced Patient Valve. It is six (6) feet in length.
Positive Pressure Face Mask The Positive Pressure Face Mask is a standard single-ported mask. It is available in

small, medium and large adult sizes.
Black Neoprene Head Harness The Black Neoprene Head Harness is used to secure the positive pressure

facemask to the patient’s face. It is a one size fits all adjustable design.

2. Installation and Assembly
2a. Suggested functional testing of Control unit prior to initial use.
Attach the included oxygen hose to the unit and to an oxygen source.

With the CPAP pressure control knob turned completely in the counterclockwise direction (against the stop), apply an
inlet pressure of 50 PSI to the Control Module. If the unit free-flows upon initial application of supply pressure,
momentarily (3-5 seconds) block the outlet. Unblock the outlet and the flow shall have ceased.

Block the outlet. Rotate the CPAP Adjustment Knob clockwise until the Airway Pressure Gauge indicates approximately
5 cmH2O. Unblock the outlet. The unit should fully flow.

Block the outlet, being careful to not block the Airway Pressure Line (small plastic tube). Slowly rotate the CPAP Adjustment
Knob to the fully clockwise position. Observe that the pressure rise indicated on the gauge needle is smooth. An outlet
pressure of 15 cmH2O or greater on the Airway Pressure Gauge indicates the unit is operating properly.

Unblock the outlet. Turn the pressure control knob back to off position. Do not force the knob against the stop. In
the majority of cases, the unit will continue to flow. Momentarily (3-5 seconds) block the outlet and then unblock. The
unit should shut off.

Contact Emergent Respiratory Customer Service if unit fails to pass these tests.

2b. Oxygen Supply
The CPAP

OS

device can use oxygen from a cylinder or from a central supply system of 40 to 60 psi. When ready to

administer CPAP therapy, connect the oxygen supply to the DISS inlet located on the side of the device.

WARNING: To prevent explosion hazard, make sure the oxygen
connector is free from oil.

NOTE: To turn the CPAP

OS

unit off, disconnect the O2 supply hose from the

source or turn off at the O2 cylinder.

CAUTION: Certain data on the use of high concentrations of inspired oxygen
show adverse effects on cardiac function in patients who have congestive
heart failure or other specific conditions. When attached to an oxygen source,
the CPAP

OS

provides an FIO2 of up to 95% dependent upon outlet flow.

NOTE: To monitor FIO

PORTO2VENT™ CPAP

OS

System Operator’s Manual

Part Number 1900-140 Rev I

CAUTION: Check the airway pressure gauge while the patient is breathing to assure that pressure is
maintained within specifications (see CPAP

OS

Specifications page 12). As the patient breathes, larger
changes in pressure shows that CPAP is not being effectively delivered. Possible causes are insufficient
source gas pressure and flow or possibly a malfunction of the CPAP unit and/or breathing circuit. Excessive
pressure variation during CPAP treatment can cause fatigue and respiratory failure.

WARNING: Potential side effects of continuous positive airway pressure may include fluid
retention, pneumothorax, decreased cardiac output and gastric distension.

4. Care and Maintenance

The housing and faceplate of the CPAP

OS
