Yes.
Explanation: The device is described as a "Universal Jet Ventilator" used to provide ventilation and supplemental oxygenation, which directly addresses a medical condition (respiratory support) and is intended for use in medical procedures like bronchoscopy and laryngoscopy.
No
Explanation: The device is described as a "Universal Jet Ventilator" used for a short-term application during bronchoscopy and laryngoscopy, primarily for ventilation and oxygenation in airway surgery and procedures. It is a therapy delivery device, not a device used to diagnose a medical condition.
No
The device description clearly outlines hardware components such as sensors, a screen display, a built-in air/oxygen blender, and a microprocessor, indicating 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:
- Intended Use: The intended use clearly describes a device used for ventilation during medical procedures (bronchoscopy, laryngoscopy, surgery). This is a therapeutic and supportive function, not a diagnostic one.
- Device Description: The description details components related to gas delivery, pressure measurement, and control of ventilation parameters. These are typical features of a ventilator, not an IVD.
- Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, urine, tissue, etc.) or to provide information for the diagnosis of a disease or condition.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not perform any such function.
N/A
Intended Use / Indications for Use
The MISTRAL Universal Jet Ventilator is designed to use for short term application in bronchoscopy and laryngoscopy.
Jet ventilation applied with the Mistral 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 Mistral Universal Jet Ventilator is intended for use during bronchoscopy or laryngoscopy for applications up to 45 minutes duration on adults in a hospital or other clinical setting.

Alarm functions
General information
In case of an alarm, the Mistral 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 Mistral 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:
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 Ventilator in case of an airway obstruction.
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 authorised 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 can not be disabled.
Specification and characteristics of the FIO2 not adjustable alarm
Application:
The Flo2 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 requlation. 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 can not 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 can not 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 instead of 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.
Error functions
Overview
The error message signals a system malfunction. The error messages can be reset by the alarm button but if the malfunction is still detected the message immediately returns to the screen. In any of these cases the Monsoon needs a service.
| Type of error | characteristic |
|---|---|
| PP sensor | the PP sensor is out of range (probably |
| disconnected or defect) | |
| DP sensor | the DP sensor is out of range (probably |
| disconnected or defect) | |
| O2 sensor is | |
| weak | O2 signal is getting to weak replace the |
