Humidity

Humidity is the presence of water vapour in gas. Absolute humidity is the amount of water vapour per litre of gas, expressed in mg/l. Relative humidity is a measure of how much water vapour is in a gas compared to its capacity to hold water vapour. It is measured as a percentage.

Principle

•When dry gas passes over a moist surface evaporation occurs and the gas becomes more humid. •When moist gas cools, water droplets condense and the gas becomes less Humid.•The warmer a gas, the more moisture (absolute humidity) it can carry. •If a gas already has 100% humidity no more moisture will evaporate into it unless it is heated further.

What is Respiratory Humidifier?

During mechanical ventilation ,When dry air/gas is administered to the patient there occurs airway cooling, airway drying ,inflammation which can lead to many complications. Optimum humidity is required for ventilation -33mg/L in non invasive mode and 44 mg/L in invasive mode. Exposure to humidity levels below 25mg H2O /l or 100% saturated gas can lead to respiratory complications. Less humidity can cause airway mucosal dysfunction and more humidity can cause reduced mucus viscosity and increased pericellular depth fluid.

To avoid the above said conditions and to administer optimal humidity. respiratory humidifiers are used during ventilation. Respiratory Humidifiers heats the water contained in the humidification chamber, humidifying the air passing through it.

Why Humidifiers are Used?

Prevent Airway Cooling

Prevent Airway Drying and Water Loss

Control Panel Operation

Temperature Probe : if the temperature probe is damaged or disconnectedHeater Wire : if the heater wire is defected or disconnectedHeater : if the heater is defected or disconnectedMaximum System Operating Pressure : 20 kPa,Gas leakage at max. Pressure : <100 mL/minute.

Alarms

•Humidified gas from the chamber pass through the inspiratory limb, where its temperature must be maintained in order to prevent the generated humidity from condensing. •This is achieved with a heater wire encapsulated within the inspiratory limb. The humidifier maintains the temperature along the inspiratory limb by monitoring the temperature at the airway probe and controlling the voltage delivered to the heater wire.• Under normal conditions the gas is heated to 40 °C in the invasive mode, 34 °C for the non-invasive mode.

Heater Wire Operation

Respiratory Humidifier maintains the airway temperature at the desired set point (invasive 37 °C or non-invasive 31 °C) by heating the chamber of water through the heater plate. As the gas cools considerably down theunheated circuit, a water trap circuit must be used to collect the resulting condensate.

Non-Heater Wire Operation

Automatic Humidity Compensation

nice 8050 Respiratory humidifier calculates the power required to adequately humidify the gas flow through the chamber. If the minimum power level is not met then the chamber set point will automatically be increased in 0.5 °C steps until the minimum power is achieved. The maximum amount of compensation applied is either 3 to 5 °C depending on the mode (Invasive/Non-invasive)If humidification is improved and too much power is being applied, then the humidifier will automatically reduce the chamber set temperature.

Display & Controls

Power SwitchThe humidifier will power ON and OFF by the rocker switch is provided in the right side of the humidifier. After power-on the humidifier starts self test which checks for possible problems in the humidifier setup. If everything is working correctly, normal control is initiated.

Mode KeyBy press mode key select humid ifier to toggle Invasive & Non-Invasive. The Mode indicator LED shows the user which mode is selected.

Invasive modeInvasive mode is for use with patients whose upper airways have been bypassed by either a tracheostomy or endotracheal tube. In this mode of operation the humidifier attempts to deliver optimal humidity to the patient (37 °C, 100 % RH).

Non-Invasive mode The humidifier normally controls the chamber outlet temperature to 31°C, and the airway temperature to 34°C, maintaining a +3°C temperature gradient alongthe inspiratory limb.

Standby ModeIf the humidifier detects a problem with its setup or operation it will alarm. Depending on the severity of the alarm condition, the humidifier will either remove all power from the heating systems, or enter stand-by. The humidifier will also enter stand-by if the gas flow through the breathing circuit has stopped. Heater wire power is set at 15%. Control of chamber temperature is attempted, within the following limits: Heater plate temperature is limited to 50°C.Mute KeyThe mute key silences the humidifier's audible alarm.Heater WireBy press heater wire key select humidifier to toggle heater wire ON or OFFCH/AW Temp KeyBy press CH/AW Temp key to shows the Chamber Actual Temperature and Airway Actual Temperature.Temperature DisplayThe front panel display window shows the saturated gas temperature (the lower of the airway and chamber temperatures in °C) delivered to the patient.

Indicators

Heater wire IndicatorHeater wire indicator LED glow if the heater wire in the breathing circuit has not been connected correctly, or if the heater wire or heater wire adaptor is faulty. An intermittent connection or excessive current (total current in all limbs > 3.5 A) in the heater wires will also produce this alarm.

Temperature / Flow Probe IndicatorTemperature Probe indicator will glow if the temperature probe is not correctly plugged in, or the probe used isfaulty. The humidifier tests for the following probe fault conditions: Temperature probe disconnected Chamber thermistor open or short circuit Airway thermistor open or short circuit Flow thermistor open or short circuit One thermistor shorted to another

Chamber Probe & Airway Probe IndicatorThese indicators are used to show that either the chamber probe or airway probe is not inserted into the breathing circuit correctly.Add Water IndicatorIf there is insufficient water in the humidification chamber, Add Water LED will glow

TROUBLESHOOTING

AND MAINTENANCE

Cleaning ProcedureCleaning the Humidifiers

It is recommended that only the following cleaners be used on the nice 8050. Clean the humidifier with one of the following recommended disinfectants using a damp cloth:

Isopropyl AlcoholSoft dishwashing detergentNote: Follow the manufacturer’s instructions carefully.Use the correct dilution of the disinfectant.DO NOT immerse the humidifier in any liquid.Wipe the humidifier clear of any cleaning residues before use.

Cleaning of Temperature & Flow Probe

1.Physically clean the probes, removing all visible contaminants.2.Disinfect the probes with one of the following solutions:Sporicidin; Sporox; Cidex & OPA OR Sterilize the probe using Ethylene Oxide sterilization at 55 °C (131 °F), 80kPa allow at least 15 hours for residual ETO to disperse before use.3. Wipe the airway temperature probes clear of any cleaning residues before use.4. Store in clean conditions.

Preventive Maintenance Checking the Humidifier

AnnuallyCheck for physical damage:Check the mains cable for damage, replace if necessary.Check the heater plate for deep scratching etc., replace if necessary.Check the heater wire adaptor for kinks, abrasions and damaged connectors. Check that the plugs couple with the sockets on the humidifier. Carry out a full performance test.

Checking the Temperature Probe

Every Six monthsa. Visually check the humidifier probes for physical damage:Check that the chamber probe's glass thermistor has not been damaged. Replace probe if required.Inspect the chamber probe's glass thermistor for deposits or foreign material. Clean probe as required.Check the probe cable for kinks and abrasions etc.Check that the probe connectors couple with the humidifier sockets.b. A temperature accuracy check and flow accuracy check should be performed on the nice 8050 temperature probe.

Cautions Use cleaning solution sparingly on a cloth when cleaning

the unit. Do not saturate the unit - excessive solution causes

damage to internal components. Do not autoclave or gas sterilize the unit. Only competent individuals trained in the repair of this

equipment should attempt to service it as detailed in the service manual. The Service Manual provides detailed information solely for use by individuals having proper knowledge, tools and test equipment, and for service representatives trained by nice Neotech .
