3OPERATION AND CONTROLS

3.1 APPLICATION

The MR810 Respiratory Humidifier is designed to heat and humidify respiratory gases delivered to the

 

patient via a face, nasal, or oral mask. The inspired gas is passed through the chamber of water where it is

 

heated and humidified. An optional heated breathing circuit (heated via a wire inside the circuit), can be

 

used to minimise condensate in the breathing circuit and maximise humidity delivery to the patient; this is

 

3

recommended.

 

The MR810 humidifier consists of two heaters: (a) a heater plate which the humidification chamber slides

 

 

onto, and (b) an optional heater-wire in the breathing circuit.

 

3.2WARNINGS AND CAUTIONS

WARNING:

Ensure probe port caps are inserted into probe ports of the breathing circuit. Caution is required when delivering gases that are not body temperature saturated.

The use of breathing circuits, chambers or other accessories which are NOT approved by Fisher & Paykel Healthcare may impair performance or compromise safety.

Refer to operating instructions for each accessory.

Ensure maintenance of grounding integrity by connection to a hospital grade receptacle.

Ensure that the humidifier is always positioned lower than the patient’s airway. Ensure the humidifier is securely mounted.

The operation of high frequency surgical apparatus, short wave or microwave equipment in the vicinity of the humidifier may adversely affect its function. If this occurs the humidifier should be removed from the vicinity of such devices.

Visually inspect accessories for damage before use. Hot surfaces may exceed 75 °C.

Do not use flammable anaesthetics. Always disconnect supply before servicing.

Caution

The MR810 does not deliver body temperature saturated gases.
