No
The device description and performance studies focus on mechanical regulation of exhalation resistance through physical ports and a handle, with no mention of AI or ML algorithms for data analysis, decision-making, or personalized adjustments.
Yes
The device is described as having a "specific therapeutic effect" by regulating the "force and flow of exhalation" and is intended to "open closed airways, enhancing aerosol deposition, increasing oxygenation and improving bronchial hygiene." These descriptions clearly indicate a therapeutic purpose.
No
The device is designed to provide controllable exhalation resistance for therapeutic purposes (enhanced aerosol deposition, increasing oxygenation, improving bronchial hygiene), not to diagnose a condition. While a manometer can be used to determine resistance, this is for setting the therapeutic effect, not for diagnostic assessment.
No
The device description explicitly states it is a "non-sterile, injection molded plastic device" and describes its physical components and how they function to regulate exhalation resistance. This indicates it is a hardware device, not software-only.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that this device is a "nebulizer accessory" that "connects to the exhalation port" and "serves to provide a controllable exhalation resistance." It is used for "enhanced medicated aerosol deposition or lung exercise."
- No Sample Analysis: The device does not analyze any biological samples from the patient. Its function is purely mechanical, affecting the physical process of exhalation.
Therefore, the Salter Labs PEP Device falls under the category of a therapeutic or respiratory device, not an in vitro diagnostic.

Intended Use / Indications for Use
The purpose of the Salter Labs PEP Device is to allow for a variable regulation of exhalation resistance through a selectable set of orifices in order to obtain a specific resistance at a given flow rate. The restriction of exhalation serves to open closed airways, enhancing aerosol deposition, increasing oxygenation and improving bronchial hygiene.
This product is indicated for use in patients where enhanced medicated aerosol deposition or lung exercise is recommended by a physician or licensed clinician. This device is intended to be used in the hospital, clinic and home care markets,
The Salter Labs PEP device is designed to be used with the Salter Labs Nebutech Nebulizerseries Mouthpiece as a stand-alone device, or the device may be used in conjunction with the Salter Labs Nebutech Nebulizer and the Salter Labs Aerosol Filter during the nebulization process.
This product is a nebulizer accessory that connects to the exhalation port of the Salter Labs Nebutech Nebulizer mouthpiece and serves to provide a controllable exhalation resustance of from 5 to 20 cm H20 at flow rates ranging from 10 to 55 L/min.

Device Description
The Salter Labs PEP Device (PEP Device) is a non-sterile, injection molded plastic device that will attach to the exhalation valve of the Salter Labs NebuTech™ Model 8960 & 8660 Nebulizer mouthpiece assembly or to the NebuTech™ mouthpiece placed in line in a 25 to 50 cm flex tube with a one-way valve at the distal opening. In either of these assemblies, the PEP Device will regulate the force and flow of exhalation to provide a specific therapeutic effect. The device is intended to be single patient use and is prescribed by a physician or licensed clinician.
The purpose of the Salter Labs PEP Device is to allow for a variable regulation of exhalation resistance through a selectable set of orifices in order to obtain a resistance at a given flow rate. The restriction of exhalation serves to open closed airways, enhancing aerosol deposition, increasing oxygenation and improving bronchial hygiene.
The Salter Labs PEP Device has a variable exhalation resistance capability. Effective exhalation resistance is determined by rotation of a "handle," located at the top of the device. The handle is connected to a disk that contains a set of predetermined exit ports. The diameter of these ports establishes the resistance to exhalation.
A manometer may be placed on the device port in order for the clinician to determine the correct resistance for each patient. This will also help the patient determine what a proper exhalation force feels like. The patient will be instructed by the clinician on proper breathing techniques and the manometer will be used to assure that exhalation pressure ranges do not exceed 20cm of water pressure, which is considered to be the maximum average therapeutic target value. The prescribing doctor or licensed clinician will determine all appropriate settings and device use and application to meet the particular requirements of his/her patient.
The Salter Labs PEP Device is unique to current predicate devices in that it incorporates a pressure relief valve. This spring-activated valve is designed to open whenever exhalation pressures exceed 20cm water pressure, thereby helping to assure consistent product performance with minimum discomfort to the patient. Instructions are included with each device, and are intended for use by the clinician in his/her instructions of device use by the patient. As with all PEP devices, this device is intended to be used by each patient according to the specific directions of his/her clinician.

System Similarities and Differences to Currently Marketed Devices
The Salter Labs PEP Device and the predicate devices upon which equivalence is sought share the same purpose: to serve as a means of producing a controllable exhalation flow resistance in order to provide a small positive pressure in the lungs for lung exercise or during nebulizer aerosol treatment. This positive pressure allows for enhanced aerosol deposition within the lungs.
Additional Remarks: Similarities and Differences to Predicate Devices:
-
- The Salter Labs PEP Device has an overpressure relief valve. The intent of this device is to provide device flow resistance to 20 cm H20, which is considered to be an appropriate therapeutic value.
-
- The Salter Labs PEP Device has been designed and is intended for use only with the Salter Labs Nebutech Nebulizer Mouthpiece. Product labeling clearly states that the PEP Device is intended for use only with the Salter Labs Nebutech Nebulizer.
