Indications for Use

For use on any patient unable to cough or clear secretions effectively due to reduced peak cough expiratory flow, resulting from high spinal cord injuries, neuromuscular deficits or severe fatigue associated with intrinsic lung disease. It may be used either with a facemask or mouthpiece, or with an adapter to a patient's endotracheal or tracheostomy tube. Clinical Settings: For use in a hospital / institutional environment, or in the home, given adequate training and a physician's prescription. Patient Population: For use on children and adults. It should not be used on neonates and infants. Contraindications: Any patient with a history of bullous emphysema, known susceptibility to pneumothorax or pneumomediastinum or known to have had any recent barotrauma, should be carefully considered before use.

Device Story

Comfort Cough (SICC2001) is a portable electric secretion clearance device. It uses an electronically powered blower and valve system to apply alternating positive and negative airway pressures, simulating a natural cough reflex (mechanical insufflation-exsufflation) to assist in clearing bronchopulmonary secretions. Operated in hospital, institutional, or home settings by trained users or patients under physician prescription. The system includes a breathing hose, face mask, adapter, and power cable. Users adjust pressure and suction levels via a user interface; a pressure gauge monitors output. The device can operate in manual or automatic modes. By generating high expiratory flow, it helps patients with impaired cough mechanisms clear airways, potentially reducing respiratory complications. It is software-controlled to manage inhalation, exhalation, and pause timing.

Clinical Evidence

Bench testing only. Compliance with IEC/EN60601-1 and 60601-1-2 electrical safety standards. Side-by-side performance testing against the Emerson Cough Assist (K002598) demonstrated similar pressure and flow rate characteristics. Emissions testing for VOCs, CO, CO2, particulate matter, and ozone conducted per US EPA TO-15, 21 CFR 801.415, OSHA ID-214, and NIOSH 0600 confirmed no significant emission of toxic substances.

Technological Characteristics

Portable electric device; blower and valve system for mechanical insufflation-exsufflation. User interface for pressure/suction adjustment; pressure gauge. Software-controlled (vs electrical switches in older predicates). Lightweight construction. Operates in manual or automatic modes. Complies with IEC 60601-1 and 60601-1-2. Compatible with external bacteria filters.

Indications for Use

Indicated for children and adults unable to cough/clear secretions effectively due to reduced peak cough expiratory flow from high spinal cord injuries, neuromuscular deficits, or severe fatigue from intrinsic lung disease. Contraindicated in patients with history of bullous emphysema, susceptibility to pneumothorax/pneumomediastinum, or recent barotrauma. Not for neonates or infants.

Regulatory Classification

Identification

A noncontinuous ventilator (intermittent positive pressure breathing-IPPB) is a device intended to deliver intermittently an aerosol to a patient's lungs or to assist a patient's breathing.

5. Description:

The Comfort Cough is a portable electric device which utilizes a blower and a valve to apply alternately a positive and then a negative pressure to a patient's airway in order to assist the patient in clearing retained bronchopulmonary secretions. It includes a means to adjust the pressure and suction levels applied, a pressure gauge to measure the pressures, and a means to reduce the positive pressure flow. The Comfort Cough system includes accessories such as a breathing hose, a face mask, an adapter and a power cable, but not a bacteria filter. The Comfort Cough can be used with a 510K cleared bacteria filter made by other manufacturers. The compatible size information is specified in the manual.

6. Indication for use:

For use on any patient unable to cough or clear secretions effectively due to reduced peak cough expiratory flow, resulting from high spinal cord injuries, neuromuscular deficits or severe fatigue associated with intrinsic lung disease.

It may be used either with a facemask or mouthpiece, or with an adapter to a patient's endotracheal or tracheostomy tube. .

· Clinical Settings: For use in a hospital / institutional environment, or in the home, given adequate training and a physician's prescription.

▪ Patient Population: For use on children and adults. It should not be used on neonates and infants.

· Contraindications: Any patient with a history of bullous emphysema, known susceptibility to pneumothorax or pneumomediastinum or known to have had any recent barotrauma, should be carefully considered before use.

7. Performance Data

· The Comfort Cough has been tested and found to comply with IEC/EN60601-1 and 60601-1-2.

· A side by side testing was performed on the Comfort Cough and the Cough Assist (K002598) to compare pressure and flow rate. The test results show that the two devices have similar performance.

· Several tests have been conducted to check if the device emits a significant amount of volatile organic compounds(VOCs), carbon monoxide(CO), carbon dioxide(CO2), particulate matters and/or ozone(02). The tests were performed in accordance with the following reference methods.

- US EPA TO-15

- 21 CFR 801.415

510(k) Submission.

{2}------------------------------------------------

- OSHA(U.S Department of Labor Operation Safety and Health Administration) Method ID-214
- NIOSH (National Institute of Occupational Safety & Health) 0600

i The test result has shown that the Comfort Cough does not emit a significant amount of toxic substances which may cause harmful effects on patients.

### 8. Summary of Technological Characteristics

The Comfort Cough is substantially equivalent to the predicate devices as described below.

#### Similarities:

- l ) The devices have the same Indications for Use.
- 2) With the same fundamental technology, all three devices produce positive and negative pressures to simulate a patient's cough reflex in a controlled manner.
- 3) The devices comply with IEC 60601 standards for electrical safety.
- 4) Pressure developed for positive and negative values are comparable.
- 5) They have electronically powered blowers to generate pressure.
- 6) They have user interface to adjust to produce positive and negative pressures.
- 7) The devices simulate a cough using "mechanical insufflation-exsufflation". This is achieved in the devices by applying a positive pressure to the airway initially and rapidly shifting to a negative pressure. The change in pressure effect produces a high expiratory flow from the lungs.
- 8) The devices can be operated in a manual or in an automatic mode.

#### Differences:

- 1) Inhalation, exhalation and pause times differ. The subject device and the Emerson controls these events to 0 to 5 seconds; whereas, the Pegaso Cough controls them from 0.1 to 9.9 seconds.
- 2) The unit weight of the subject device and the Pegaso is almost half less than the Emerson unit through use of light weight materials.
- 3) The subject device and the Pegaso Cough is software controlled whereas the Emerson device is controlled by electrical switches.

#### 9. Basis for Substantial Equivalence

Upon reviewing the safety and effectiveness information including testing data provided in this submission and comparing intended use, principle of operation and overall technological characteristics, the Comfort Cough is determined to be by SEOIL PACIFIC CORP. to be substantially equivalent to the predicate devices.
