Intended Use
The Monsoon Universal Jet Ventilator is designed to use for bronchoscopy and laryngoscopy. Jet ventilation applied with the Monsoon Universal Jet Ventilator is useful in airway surgery, as it is performed in thoracic surgery units and ENT surgery. Jet ventilation is the optimal ventilation technique during the application of LASER light, where the presence of an ETT bears the risk for ignition, airway fire and burn injuries. Jet ventilation is useful for the removal of foreign bodies from the airway (e.g. after accidental aspiration of foreign bodies) via rigid bronchoscopes, for supplemental oxygenation during lung surgery (when the operated lung must be recruited for additional oxygenation, but may not be ventilated conventionally for surgical reasons), for surgery of the lower trachea close to the carina (when during the reconstruction phase, no tight airway sealing can be achieved), for radiation therapy of lung metastasis (when the tidal movements of the chest during spontaneous respiration or conventional ventilation would preclude the focusing of the radiation beam onto the target. The Monsoon Universal Jet Ventilator is intended for use during bronchoscopy or laryngoscopy in a hospital or other clinical setting.
Device Description
In the past time, a jet ventilator system consisted of a jet ventilator and a humidifier, both made as individual units in separate enclosures. Now, those components in electronics became smaller and smaller, both units have been put together in one enclosure. One of the key features of the MONSOON is the safety concept to avoid having excessive pressures occurring in the patient's airways. To reach this goal, a high pressure resistant sensor with excellent resolution in the working range of 1 to 200 cmH2O is used. Another new feature in airway pressure measurement is the use of a small bias flow going through the airway pressure line, to eliminate the dead-space of the airway pressure line. In addition, the bias flow avoids, bacteria and humidity going back into the machine, creating contamination. If the airway pressure line is occluded, the bias flow makes the pressure rising and the ventilation is stopped immediately. A large screen displays the main parameters of ventilation and allows quick information of the anaesthetist about the status of the ventilation. A graphic indication of the airway pressure makes quantitative reading possible and allows quick access for parameter changes. Special functions are activated in menus and displayed on the screen. The MONSOON has a built in blender, which allows concentrations between 21 and 100 % oxygen. The access for changes is via a knob on the front panel. This parameter is accessible without going into menus, to allow a rapid change in case of emergency. The MONSOON uses an oxygen sensor, which is calibrated each time the unit, is switched on. If the ventilator can't reach the selected FiQ2, an alarm message appears on the screen, informing about a problem in the qas supply. The MONSOON has an additional outlet for gas, which can be adjusted from 0 to 70 LPM and a concentration between 21 % and 100 %. This feature allows mask ventilation of the patient for induction in anaesthesia or for emergency ventilation with a manual breathing bag. The MONSOON is equipped with a heating and humidification system, controlled by the microprocessor, which automatically adjusts the water injection and temperature of the jet gas. The water supply is based on the minute volume and therefore quarantees an efficient climatisation of the gas. In the MONSOON, the gas is preheated prior the injection of the water and therefore a saturation of the gas is achieved much easier. On the ventilator, all changes affecting the minute volume are controlled by the microprocessor, resulting in a reduction or increase of water injection. The temperature is controlled by a PT-100 temperature sensor and for safety; a thermostatic switch shuts down the heating system in case of a system failure. If the water supply is occluded or the bottle is empty, an alarm message on the screen informs the operator. The MONSOON has a small roller pump mounted on the right side of the unit, allowing easy access. A standard IV set is used to connect the bottle with the pump inlet.

More Information

Not Found

No
The document describes a microprocessor-controlled device with various sensors and safety features, but there is no mention of AI or ML algorithms for data analysis, decision-making, or learning. The control logic appears to be based on predefined parameters and sensor inputs.

Yes
The device is a jet ventilator designed to provide ventilation during medical procedures, which directly supports and maintains physiological functions.

No

Explanation: The device is a jet ventilator designed for therapeutic purposes, specifically for ventilation during bronchoscopy and laryngoscopy, including airway surgery, LASER light application, foreign body removal, and supplemental oxygenation. While it includes sensors for monitoring ventilation parameters, these are for controlling the ventilation process and ensuring patient safety, not for diagnosing medical conditions.

No

The device description clearly outlines numerous hardware components, including sensors, a screen, a blender, a heating and humidification system, a roller pump, and a microprocessor. This indicates it is a physical medical device with integrated software, not a software-only device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
  • Device Function: The Monsoon Universal Jet Ventilator is a medical device used to provide ventilation (breathing support) to patients during specific medical procedures (bronchoscopy and laryngoscopy). It directly interacts with the patient's airway.
  • Intended Use: The intended use clearly describes its application in surgical and clinical settings for airway management and ventilation, not for analyzing biological samples.
  • Device Description: The description details components related to gas delivery, pressure monitoring, humidification, and control systems, all of which are consistent with a respiratory support device, not an IVD.

Therefore, the Monsoon Universal Jet Ventilator falls under the category of a therapeutic or life support medical device, not an In Vitro Diagnostic device.

Alarm functions

General information

In case of an alarm, the MONSOON will display the alarm message on the screen and an acoustic alarm sounds. The acoustic alarm is ceased as soon as the alarm condition is cleared. However, the screen message remains until it is confirmed by pressing the alarm reset button. If you press alarm reset button while the alarm conditions is not cleared, there is an alarm mute for 1 minute activated, which depresses the acoustic alarm for this period. The screen inverses to make the user aware that the alarm mute is active.

The Monsoon has an alarm concept to allow a safe use of the equipment for patient and operator. The following section shows the different alarm types and their sources:

PIP too high:

This alarm is activated if the airway pressure exceeds the set limit. It is only measured if the Proximal Pressure line is connected with the unit and therefore requires double lumen catheters.

PIP disconnect:

This alarm is activated if there was no pressure detected in the Proximal Pressure Line

PP too high:

This alarm is activated if the pressure in the Jet line remains above the set limit for the PP pressure. This alarm is a safety feature for the use of Jet Ventilation with single lumen catheters. It allows a security shut-off of the Jet Vertilator in case of an airway obstruction.

add water.

This alarm is activated when the water-detector in the unit doesn't detect any water.

System alarms

General information

These alarms signal the user a state of improper function of the device. There is no immediate danger to the patient but the device should be replaced and serviced by authorized personal (exception: low level of pressure input).

Specification and characteristics of the ventilation alarm

Application:

The ventilation device makes sure that max. oxygen level in the Jet ventilator is below a level of concern. The ventilation is periodically checked for ether disconnect (alarm level 1) or overload (alarm level 2) of the fan. This is an alarm, which cannot be disabled.

Specification and characteristics of the FIO2 not adjustable alarm

Application:

The FIO2 not adjustable alarm is evoked as soon as the O2 level can not be adjusted because of any other reason than missing ether O2 or airway pressure. There could be a mechanical problem or a system malfunction of the O2 regulation. If the O2 sensor could not be calibrated this alarm is also set active.

Specification and characteristics of the low O2 pressure alarm

Application:

The O2 pressure is continuously watched by the controller and goes on if there is not enough pressure on the O2 inlet. This is an alarm, which cannot be disabled. The alarm resets itself if pressure is sufficient.

Specification and characteristics of the low air pressure alarm

Application:

The air pressure is continuously watched by the controller and goes on if there is not enough pressure on the air inlet. This is an alarm, which cannot be disabled. The alarm resets itself if pressure is sufficient.

Specification and characteristics of low bat alarm

Application:

Battery level is measured and in case of a worn out battery the message "low bat" is displayed next to the time and date. There is no alarm going off because the battery is not used unless the power failure fault. This battery has not a data backup function. In case of "low bat" a replacement of the battery is sufficient.

Specification and characteristics of Power failure alarm

Application:

Main-line is less than 95 VAC the beeper on the back panel sounds with interval supplied by battery power. This is an alarm which can not be disabled.

Specification and characteristics of MAINTENANCE REQUIRED alarm

Application:

Mistral has an integrated timer function for servicing intervals. After one year, on the display the message "MAINTENANCE REQUIRED" appears. The unit may still be used, however, a service engineer must be called for servicing of the equipment to assure a proper function.
