Intended Use

AnapnoGuard 100 Respiratory Guard System is intended for airway management by oral/nasal intubation while providing continuous endotracheal cuff pressure control using non-invasive measurement and monitoring of carbon dioxide concentration in the subglottic space and evacuation of secretions from above the endotracheal tube's cuff.

Device Description

AnapnoGuard 100 Respiratory Guard System is comprised of the following three main components: The AnapnoGuard endotracheal tube (ETT) with inflatable cuff (FDA cleared under K093126). The AnapnoGuard 100 Respiratory Guard System interconnection harness of tubes, connecting the ETT to the AnapnoGuard 100 control unit The AnapnoGuard 100 Respiratory Guard System control unit which consists of the following main modules: Host computer (PC) Microcontroller (MCU) Suction module (regulator and flow potency meter): including . a set of valves and pipes controlling the secretions suction/evacuation from above the ETT cuff. Rinsing module: Pumps saline to rinse the Suction and Vent/ ● CO2 lumens. CO2 analyzer module: including CO2 analyzer assembly, ● pump, valve and flow filter which sucks air from the subglottic space above the ETT cuff into the CO2 analyzer. . Cuff pressure module: includes two pressure gauges which monitor cuff pressure, a miniature air pump and two valves. Pneumatic module: valves, pipes and filters . Connectors panel for connecting the interconnection harness . (ETT), vacuum, trap bottle, rinsing fluid and filters. Operation buttons panel and navigation wheel . I/O communication panel . Display monitor . AnapnoGuard 100 Respiratory Guard System, including its three components monitors leak between the endotracheal tube's cuff and the trachea by measuring the Carbon Dioxide levels in the subglottic area above the cuff through a dedicated lumen in the endotracheal tube. Detection of a high level of Carbon Dioxide is an objective indicator for a leak (improper sealing of the trachea by the endotracheal tube cuff). The system continuously monitors and adjusts the cuff pressure to prevent a leak at minimum possible pressure (all within pressure limits preset by the user). Preventing a leak reduces the likelihood of aspiration of secretions from the upper airways into the lungs and increases the likelihood for no loss of ventilation and delivery of anesthetic and nebulized drugs into the lungs. Keeping the cuff pressure as low as possible reduces the mechanical pressure of the cuff on the tracheal tissue throughout the intubation period. The system also performs evacuation of secretions from above the endotracheal tube's cuff through a dedicated lumen at the dorsal side of the endotracheal tube.

Study Details

Here's a breakdown of the specific information requested regarding the studies:

2. Sample size used for the test set and the data provenance:

  • Test Set Sample Size: The clinical study enrolled intensive care and post-operative patients expected to be mechanically ventilated for at least 12 hours. The exact number of patients is not explicitly stated in the provided text.
  • Data Provenance: The study was a prospective, two-arms controlled and multi-center study. The country of origin is not specified, but the applicant (Hospitech Respiration Ltd) is based in Israel, suggesting the study might have been conducted there or internationally.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • This information is not provided in the text. The ground truth for the clinical study was based on objective measurements by the AnapnoGuard 100 control unit itself (CO2 levels, cuff pressure measurements) rather than human expert interpretation of an image or signal for diagnostic purposes.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

  • None (N/A): The clinical study did not involve human interpretation requiring adjudication. The primary endpoints (CO2 AUC, cuff pressure measurements, significant leakages) were direct, quantifiable output from the device.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

  • No: An MRMC comparative effectiveness study was not conducted. This device is not an AI diagnostic tool that assists human readers in interpreting data; rather, it's an automated system for managing airway parameters. The study compared the device's automated full clinical mode against a "standard of care" manual monitoring approach, not human readers with or without AI.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

  • Yes, effectively: The "Study group" in the clinical trial represents the AnapnoGuard 100 Respiratory Guard System operating in its "full clinical mode, where the subglottic secretions suction and cuff pressure control was enabled (ON mode)." This is a standalone performance of the device's automated functions without continuous human intervention to adjust cuff pressure based on leak detection. The "Control group" was monitored manually, but the device's CO2 detection was still used to measure outcome. The results directly reflect the performance of the device's integrated algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

  • The ground truth for the clinical study's primary and secondary endpoints was based on objective, quantitative measurements obtained directly from the AnapnoGuard 100 control unit. This includes:
    • CO2 levels in the subglottic space (to determine cuff leakage).
    • Cuff pressure measurements.

8. The sample size for the training set:

  • The document does not mention a training set in the context of machine learning or AI models. Given the device's nature (closed-loop control system rather than a diagnostic AI), it likely uses pre-programmed logic and algorithms based on physiological principles rather than a trainable model from a large dataset. Therefore, a "training set" as commonly understood in AI/ML is not applicable or not disclosed.

9. How the ground truth for the training set was established:

  • As a training set (in the AI/ML sense) is not mentioned or implied, the method for establishing its ground truth is not applicable or not provided. The device's operation is based on established engineering and physiological principles.

Summary of Clinical Performance Data:

Background

The clinical performance of the AnapnoGuard 100 Respiratory Guard System as airway management tool in mechanically ventilated patients was evaluated in prospective, two arms controlled and multi-center study.

Methods

The study included intensive care and post-operative patients expected to be mechanically ventilated for at least 12 hours. Following screening and enrollment, patients were randomized to study or control group.

Study group patients were intubated with the AnapnoGuard ETT and connected to the control unit of the AnapnoGuard 100 Respiratory Guard System operating in its full clinical mode, where the subglottic secretions suction and cuff pressure control was enabled (ON mode).

{13}------------------------------------------------

Control group patients were treated according to the current standard of care- patients were intubated with the AnapnoGuard ETT and connected to the control unit of the AnapnoGuard 100 Respiratory Guard System where the subglottic secretions suction was enabled but cuff pressure control was disabled (OFF mode). The cuff pressure in the control group was monitored manually according to standard of care in the ICU. In both groups, the presence of CO2 levels above the cuff was measured by the AnapnoGuard 100 control unit.

The primary end point of the study was the overall duration and level of around ETT cuff leakage (determined by CO2 Area under the Curve (AUC)). Secondary end points included number of cuff pressure measurements within the safety accepted range (24 to 40cmH2O) and number of significant CO2 leakage (readings at ≥2mmHg in the subglottic space). The non-inferiority hypothesis, compared to the standard of care use today was tested (by the primary endpoint). In addition, the performance safety of the AnapnoGuard 100 Respiratory Guard System system was evaluated by monitoring and recording device related adverse events.

Results

The average AUC of CO2 leakage, calculated for the study group was significantly lower compare to control group (0.09±0.04 vs. 0.22±0.32 respectively, This result was found to be statistically significant (p<0.001). The significant reduction in CO2 leakage in study group indicates the efficacy of the AnapnoGuard 100 Respiratory Guard System (while operating in full clinical mode) in optimizing cuff pressure, and the efficacy of AnapnoGuard 100 Respiratory Guard System as airway management tool.

Additional aspects of cuff pressure control during mechanical ventilation were:

  • Number of cuff pressure measurements within the safety accepted range. Study result indicated that the normalized number of cuff pressure measurements within the safety range in the Study group more than twice the result of the control group (mean ratio Study / Control= 2.03, P<0.001).
  • Measurements of significant leakages (CO2) were significantly lower in Study group compare to control group
