No
The device description and performance studies focus on mechanical components and aerosol delivery, with no mention of AI or ML.
Yes
The device is described as "a Positive Expiratory Pressure Device for patients suffering from Cystic Fibrosis, lung diseases with secretory problems, and to prevent or reverse atelectasis," indicating its clear therapeutic purpose.
No
The device is described as a "Positive Expiratory Pressure Device for patients suffering from Cystic Fibrosis, lung diseases with secretory problems, and to prevent or reverse atelectasis." Its function is therapeutic, assisting with breathing and secretion removal, rather than diagnosing a condition.
No
The device description clearly outlines physical components like a resistor, pressure range indicator, pressure port adapter, mouthpiece, and mask, indicating it is a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for therapeutic purposes (Positive Expiratory Pressure Device for patients with lung diseases, preventing/reversing atelectasis, and potentially used with aerosol drug therapy). It is designed to directly interact with the patient's respiratory system for treatment.
- Device Description: The description details a mechanical device for breathing exercises and drug delivery, not for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
The device is a respiratory therapy device used for treatment, not for diagnostic testing.

Device Description
The DHD TheraPEP® is a single-patient-use Respiratory Therapy device. The standard system consists of a resistor, pressure range indicator, pressure port adapter, and mouthpiece. The mask may be substituted for the mouthpiece. Pressure monitoring is optional, and the pressure port adapter is removable.
Air and aerosolized drugs are drawn in through the inlet of TheraPEP, which is opposite the mouthpiece end of the device. The air and aerosolized drug passes by the inlet valve which baffles out some of the medication, primarily large diameter particles of aerosolized drug which can not be absorbed by the patient's lung tissue. The air and respirable diameter particles of the aerosolized drug continue undeterred past the inlet device and through the device past the mouthpiece and into the patient's body. As the user begins exhaling, the inlet valve closes, forcing all of the air from the lungs out the selected orifice in the selector dial.
The MDI with spacer or Nebulizer may be connected directly or by means of an adapter to the 22mm O.D. inlet end (opposite mouthpiece end) of the TheraPEP device. Positive Expiratory Pressure (PEP) occurs during exhalation and aerosol drug delivery occurs during inspiration. Use of an MDI Spacer and/or Nebulizer requires the same technique of breathing for inhalation and breath hold as does PEP therapy. A patient would be instructed by a clinician to take in a larger than normal breath for PEP Therapy or Aerosol Drug delivery followed by a short breath hold prior to exhalation. PEP occurs during exhalation and helps prolong exhalation plus keeps airways open longer thereby helping to move secretions, increase the transpulmonary pressure gradient, and resolve atelectasis.

Summary of Performance Studies
The purpose of Phase I was to complete particle size distribution data using cascade impaction measurement, for the effect of expiratory resistance on metered dose inhaler (MDI) and small volume nebulizer (SVN) delivery of aerosolized albuterol (Proventil® and Proventil HFA) by metered dose inhaler (MDI) and aerosolized albuterol (Proventil®) by SVN. These tests were conducted using various products currently on the market such as the 1) Ace® Aerosol Cloud Enhancer MDI Spacer, and three brands of SVN's, Airlife Misty Neb, Salter Neb and the Vortran Uni-Heart using albuterol sulfate (Proventil®), solution for inhalation.
The purpose of Phase II evaluation testing was to complete particle size distribution data using cascade impaction measurement, for the effect of expiratory resistance on small volume nebulizer (SVN) delivery of aerosol medication. Specifically, the effect of two expiratory resistance devices (TheraPEP, Resistex) on nebulized drug delivery was investigated usinq metaproterenol (Alupent®) and cromolyn sodium (Intal ®). This represents follow-up measures to the previous project testing MDI and nebulizer delivery of albuterol (Proventil®) with expiratory resistance.
The conclusions drawn from this evaluation were that there is no difference in albuterol drug delivery for MDI with the Ace® spacer, with or without the TheraPEP® attached in place of the Ace® mouthpiece, for either the CFC or the HFA formulations of albuterol. The results reported also indicate that there is no difference in albuterol drug delivery with the Misty Neb, the Salter or the Uni-Heart nebulizers between the TheraPEP® and the Resistex®.
Additional conclusions drawn indicate that there is no difference statistically in either total drug mass delivered, or respirable drug mass delivered, with Intal® (cromolyn sodium) or with Alupent® (metaproterenol suffate) between the TheraPEP® and the Resistex devices attached to any of the three brands of nebulizer (Misty Neb, Salter, Uni-Heart). In each individual trial, larger amounts of total and respirable drug mass, for both drugs, were recovered with the TheraPEP® compared to the Resistex® device. However, the greater drug delivery with the TheraPEP® did not achieve statistical significance with the small sample size (n=3) and with the conservative nonparametric Wilcoxon statistic.
The added claim (the device may be combined with aerosol drug delivery) for PEP therapy will not adversely affect the safety and effectiveness of the TheraPEP device when utilized for this application.
