Introduction

Welcome

Thank you for choosing the GE Healthcare CARESCAPE® R860. Our goal is to provide you with the highest quality product and services available. This ventilator features a user interface specifically designed to streamline workflow while providing exceptional insight into patient needs.

Connecting the breathing circuit

WARNING

Do not use antistatic or electrically conductive breathing tubes or masks.

Check all connections to the breathing circuit to make sure that there are no unintended connections made to other equipment, especially equipment that delivers fluids, as the patient could be harmed.

The inspiratory safety guard is required to connect the breathing circuits to the ventilator. The inspiratory safety guard must be used at all times during ventilation.

Note

See "Cleaning and maintenance" for information on the replacement of the inspiratory safety guard. See "Parts and accessories" for ordering information.

The exhalation valve heater should be used when an active humidifier with a heated expiratory limb is used.

Important

Consult your hospital guidelines for proper use of expiratory filters in conjunction with heated humidifiers.

2065492-001

Connecting a HME (heat and moisture exchanger)

Note

To prevent excessive resistance in the breathing circuit, the HMEF500 should not be used for Adult patients.

Note

If using optional accessories see Figure in "Connecting the Pedi-lite(+) and D-lite(+) sensors".

1. Connect the inspiratory safety guard to the inspiratory port.

2. Attach the inspiratory limb of the patient circuit to the inspiratory safety guard.

3. Attach the expiratory limb of the patient circuit to the expiratory port or expiratory filter (if used).

4. Connect the Pedi-lite(+) or D-lite(+) sensor to the patient wye (if used). Use a 5 ml (minimum) spacer and elbow when using the Pedilite(+) or D-lite(+) sensor.

5. Connect the HME.

• Place the HME between the SpiroDynamics catheter (if used),

but after the Pedi-lite(+) and D-lite(+) sensor (if used).

• The HME should be removed when a nebulizer is active.

Replace the HME when the nebulizer is not in use.

6. Connect the circuit elbow to the HME (if used).

Note

To disconnect, follow instructions in reverse order.

Connecting the humidifier

The ventilator is designed to work with active humidification. GE Healthcare recommends the use of the Fisher & Paykel MR850 humidifier (refer to humidifier instructions for detailed information on humidifier connections and use).

WARNING

Never position any filter in the inspiratory limb downstream of a humidifier.

When adding attachments or other components to the ventilator, the pressure gradient across the breathing circuit may change.

1. Slide the humidifier heater onto the accessory rail (do not plug in).
