The VADI VH-1500 is a respiratory humidifier designed to heat and warm breathing gases before they enter a patient's airway. It is intended for use by qualified medical staff with medical gloves in professional healthcare facility environments, such as hospitals.
Function Description
The device provides nine temperature settings, with the highest power level delivering the highest amount of vaporized water. It can be used for patients of all ages, including neonates, children, and adults, who have upper airway malfunction. The VH-1500 is compatible with any ventilator, including those with servo control and invasive ventilation, and can provide a maximal flow rate of 40 LPM.
The humidifier features a control panel with three main buttons:
- Power On/Off: Turns the device on or off.
- + Heating-power Up (Silence Button): Increases the heating level. Pressing this button also silences the alarm signal for 2 minutes, after which the alarm signal resumes.
- - Heating-power Down (Silence Button): Decreases the heating level. Pressing this button also silences the alarm signal for 2 minutes, after which the alarm signal resumes.
The power level scheme on the control panel indicates the temperature of the heater plate. A setting of '0' indicates standby, where the heater plate is not heated.

Usage Features
- Installation:
- Slide the device onto the bracket.
- Slide the chamber onto the heater base. Users should choose the appropriate chamber (adult, pediatric, or neonatal).
- Add distilled water into the chamber (up to 300 C.C.) or stab distilled water with an IV-SET needle and connect the tube to the humidification chamber.
- Connect the tube from the gas supply to the inlet port of the chamber and the inspiratory part of the circuit to the outlet port.
- Water Level: The water level should not exceed the highest level and should not be less than the lowest level.
- Device Positioning: The device cannot be leaned over 10°.
- Water Condensation: Condensed water in the circuit is not acceptable. Water traps are recommended to collect condensation.
- Heater Plate Safety: Do not touch the heater plate during operation.
- Flow Requirement: If there is no flow, turn off the humidifier.
- Absorbent Paper: Recommended for use to increase temperature and moisture performance.
- Dry Heating: It is not allowed to heat the chamber without distilled water.
- Temperature Monitoring: A thermometer is recommended for more accurate temperature data on the patient's side, as the temperature at the patient's side may differ from the heater plate's due to tubing size, length, flow rate, and room temperature.
- Over-heated Protection: If the heater temperature exceeds 95 ± 6°C, power to the heated plate is discontinued, and the Power-on/off function will not be operative.
- Low Temperature Alarm: 30 minutes after operation, if the heater plate temperature is 5°C lower than the setting, the display will show "L" and an alarm will sound.
- High Temperature Alarm: If the heater plate temperature is over 85 ± 3°C, the display will show "H" and an alarm will sound.
Maintenance Features
- Disposition: Dispose of the humidifier according to local rules for electronic devices.
- Cleaning: The heated plate may be wiped with a damp cloth using clean water or 75% ethyl alcohol.
- Regular Checks:
- Check the power cord for damage; replace if necessary.
- Check the heater plate for scratching, dirt, or moisture; replace if necessary.
- Conduct cleaning when necessary.
- Reprocessing of Accessories:
- Breathing Circuit:
- Dismantle all components except the stainless steel spring attached to the body of the water trap.
- Clean parts with low-flow running water, using a soft brush to remove all foreign material (e.g., soil or organic matter).
- Sterilize by autoclave: 132°C / 4 minutes.
- Chamber:
- Clean parts with low-flow running water, using a soft brush to remove all foreign material (e.g., soil or organic matter).
- Sterilize by autoclave: 132°C / 4 minutes.
