Intended Use
ExSpiron 2Xi is indicated for use by healthcare professionals in healthcare facilities, such as post-operative care and critical care units, to monitor breathing in patients at least 1 - year of age. ExSpiron 2Xi is a non-invasive monitor that graphically displays lung volume against time and reports an approximate value of: - Minute Ventilation (MV) - Tidal volume (TV) - Respiratory Rate (RR) ExSpiron 2Xi measurements are used as an adjunct to other clinical information.
Device Description
The ExSpiron 2Xi Respiratory Monitor System consists of: Monitor: The Monitor contains a bioimpedance measurement system and a tablet PC housed within a single enclosure. Bioimpedance measurement system: The Monitor incorporates a stabilized high frequency current generator and an adaptive circuit that conditions the resulting voltage signal and converts it to digital form. Firmware within the Monitor performs signal acquisition and relays data to the tablet PC. Computer: A tablet PC performs signal processing and calibration and runs the graphical user interface (GUI). The PC takes user input from a touch screen through a virtual keyboard and mouse. The GUI is used for recording patient data and displaying the respiratory trace as well as scalar values and trends for minute ventilation, tidal volume, and respiratory rate. Patient Cables and Electrode Padsets that are also included in the system but were cleared in previous 510(k)s: K130170, K162131, K173181 ExSpiron Patient Cable: A reusable cable that connects the ExSpiron 2Xi Monitor to the Electrode PadSet. Single patient use ExSpiron Electrode PadSet: A Single-Patient Use Electrode PadSet is placed on the skin of the patient's torso. It delivers current to, and records impedance measurements from, the skin.
More Information

Yes
The description explicitly mentions a "proprietary, non-linear, regressive model trained with a dataset containing respiratory data from a large historical cohort," which is characteristic of a machine learning approach.

No
The device is described as a non-invasive monitor that displays lung volume, minute ventilation, tidal volume, and respiratory rate, and its measurements are used as an "adjunct to other clinical information." It monitors breathing but does not directly treat or alleviate a medical condition.

No

The device is described as a non-invasive monitor that graphically displays lung volume against time and reports approximate values for Minute Ventilation (MV), Tidal volume (TV), and Respiratory Rate (RR). It is used to "monitor breathing" and its measurements are "used as an adjunct to other clinical information." It does not identify or diagnose a disease or condition, but rather provides physiological parameters for monitoring purposes.

No

The device description explicitly states that the system consists of hardware components including a Monitor containing a bioimpedance measurement system and a tablet PC, patient cables, and electrode padsets.

Based on the provided information, the ExSpiron 2Xi is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • ExSpiron 2Xi Function: The ExSpiron 2Xi is a non-invasive monitor that measures respiratory parameters (Minute Ventilation, Tidal Volume, Respiratory Rate) by applying a current to the patient's torso and measuring impedance. It does not involve the collection or analysis of specimens from the body.
  • Intended Use: The intended use is to monitor breathing in patients, not to analyze biological samples for diagnostic purposes.

Therefore, the ExSpiron 2Xi falls under the category of a non-invasive physiological monitor, not an In Vitro Diagnostic device.

No
The letter does not explicitly state that the FDA has reviewed and approved or cleared a PCCP for this specific device. The provided text indicates "Control Plan Authorized (PCCP) and relevant text Not Found".
