Covidien Puritan Bennett 840 ventilator Exhalation Flow Sensor Q3 PN 4-072212-SP

► Brief Introduction

The exhalation flow sensor (Q3) provides flow information on exhaled gas. Flow sensor measurements are used to determine net gas flow to the patient and spirometry

During exhalation, patient gas enters the exhalation system from the patient circuit. The ventilator actively controls the exhalation valve (EV), opening and closing it in precise increments throughout inspiration and exhalation. Such precise control of the valve allows the ventilator to deliver aggressive breaths while minimizing pressure overshoots, controlling PEEP, and relieving excess pressures. The exhalation module also performs spirometry of the exhaled gas and monitors flow sensitivity.

The exhalation heater (EXH HTR) heats the exhaled gas to minimize moisture in the exhalation module, while thermistors provide the ventilator with temperature feedback. The expiratory pressure transducer (PE), on the exhalation transducer PCB, and the exhalation flow sensor (Q3) provide readings used in breath delivery alculations.

► Installing exhalation flow sensor (Q3)

1 If you are installing a new Q3, remove caps from both ends.

2 Make sure O-rings at both ends of Q3 tube are in place.

3 Orient body of Q3 with harness connection facing up.

4 Gently insert longer portion of tube into heater port.

5 Connect cable to connector on Q3.

6 Install exhalation valve.

► Running Flow Sensor Calibration

1 Enter Service Mode.

2 Ensure both air and oxygen are connected to the ventilator.

3 Connect the gold standard circuit between the To Patient and From Patient ports.

4 Ensure that there are no leaks or occlusions by running EST and ensure that the ventilator passes the EST Leak Test. Once this test has passed, exit EST.

5 Select the Other Screens button.

6 Select Flow Sensor Calibration.

7 Press the Start button and press Accept.

The ventilator automatically starts the calibration. When the calibration is complete, press the Other Screens button again to return to the Other Screens menu.
