If the temperature is less than desired on your GGM Humidifier and there is no alarm, the humidifier may be in the process of warming up. Wait for a few minutes to see if the temperature reaches the desired level.
Why is there excessive water in the inspiratory circuit of my GGM VH-2600?
Excessive water in the inspiratory circuit of the GGM Humidifier, also known as rainout, can occur for several reasons. If in non-heated wire mode, reposition the water trap to the lowest point of the circuit. If in heated wire mode, increase the distance from the heater wire to the temperature probe so that the distance is between 25 mm and 100mm, ideally 30mm. If the inspiratory circuit is being cooled by an air conditioner, shield the circuit or use a heater wire circuit. If the chamber control is set too high, reduce the setting. If the maximum permissible peak flow rate of the humidification chamber has been exceeded, use the correct chamber referring to the operating instructions for the chamber type. Ensure the chamber is level. Finally, check the temperature probe for any faults.
How to fix airway temperature low alarm on GGM VH-2600 Humidifier?
If the airway temperature low alarm is activated on your GGM Humidifier, first check the position of the temperature probe in the circuit. If the gas flow has stopped or been interrupted, turn the humidifier off until gas flow resumes. Ensure the temperature probe is correctly fitted in its housing. Also, ensure the gas flow rate is more than 5 liters per minute; increase it if it's too low.
What to do if the chamber temperature high alarm is activated on GGM VH-2600?
If the chamber temperature high alarm is activated on your GGM Humidifier, first refill the humidification chamber if there is no water in it. Also, check the chamber sensor on the temperature probe for faults.
How to resolve airway temperature high alarm on GGM Humidifier?
If the airway temperature high alarm is activated on your GGM Humidifier, wait for the temperature to fall below the threshold if there was a sudden spurious increase in gas flow. If the heater wire is too close to the temperature probe, adjust the wire or hose so that the distance is between 25 mm and 100 mm, ideally 30 mm. Check the airway sensor on the temperature probe for faults.
What does ‘ER.03’ mean on my GGM Humidifier display?
If you see ‘ER.03’ on your GGM Humidifier display, it indicates the heater plate is broken or the heater plate overheated protector has been activated. You can try to reset the overheated protector. If that doesn't work, the unit may need repair.
What to do if the expiratory heater wire alarm goes off on my GGM VH-2600 Humidifier?
If the expiratory heater wire alarm activates on your GGM Humidifier while the temperature is still displayed, the expiratory heater wire may be broken. Replace the heater wire, or push the HEATER WIRE button twice.
How to troubleshoot a breathing circuit leak in GGM VH-2600 Humidifier?
If the GGM Humidifier has a breathing circuit leak, check all circuit connections. Ensure the water bag is connected. Also, check that the temperature probes are correctly fitted and connected.
What does temperature probe alarm ‘C.SHT’ mean on the GGM VH-2600 Humidifier?
If your GGM Humidifier displays a temperature probe alarm ‘C.SHT’, it means the chamber temperature probe is short. Replace the probe.
What does temperature probe alarm ‘A.SHT’ mean on my GGM VH-2600 Humidifier?
If your GGM Humidifier displays a temperature probe alarm ‘A.SHT’, it means the airway temperature probe is short. Replace the probe.

This document describes the GGM Respiratory Gas Humidifier, models VH-2600 and VH-2600A, a medical device designed to add heat and moisture to respiratory gases for patients in an Intensive Care Unit (ICU). The humidifier passes gas through a humidification chamber where it is warmed and humidified. It monitors the gas temperature at the chamber outlet using a chamber probe and controls the power delivered to the heater plate to maintain a set chamber temperature.
The primary function of the GGM Respiratory Gas Humidifier is to provide humidity to breathing circuits or masks for patients. It features two heating systems: a heater plate that warms the water in the humidification chamber and, in certain modes, a heater wire within the breathing circuit to further heat respiratory gases. The device includes various probes to monitor temperatures at different points in the system, ensuring optimal and safe humidification.
