Intended Use

The ISO-Gard® Mask is intended to be used to scavenge waste anesthetic gases from patients during recovery from general anesthesia and to provide supplemental oxygen. The ISO-Gard® Mask helps to reduce the amount of anesthetic agents released to the work environment of the healthcare worker.

Device Story

ISO-Gard Mask is an oxygen delivery mask for patients recovering from general anesthesia in the PACU. It connects to an institutional regulated vacuum source to actively scavenge exhaled waste anesthetic gases (WAGS), reducing exposure to healthcare workers. The device also delivers supplemental oxygen and includes an ETCO2 monitoring port. It features a divided manifold to separate oxygen delivery from scavenging, and entrainment valves to manage excess negative or positive pressure. The mask is secured to the patient via an elastic strap and includes a foam bridge pad for sealing. Healthcare providers use the mask to aid patient recovery while maintaining a safer work environment. The device is a passive/active hybrid system; it functions as a standard oxygen mask with or without vacuum suction.

Clinical Evidence

Bench testing only. Testing evaluated oxygen delivery performance at variable flow rates and vacuum levels, scavenging performance (N2O levels) compared to a standard medium concentration mask, and ETCO2 waveform consistency. Results demonstrated that the device meets performance requirements and is equivalent to the predicate.

Technological Characteristics

Oxygen delivery mask with integrated scavenging manifold. Materials: PVC (mask, tubing), natural ester foam with acrylic adhesive, thermoplastic elastomer, polyisoprene (valves), polystyrene, polypropylene, polyester. Features: divided manifold for gas separation, one-way flapper/diaphragm entrainment valves for pressure regulation, ETCO2 sampling port (female luer lock). Connectivity: connects to wall oxygen and wall vacuum. Form factor: adult size, elastic strap fixation. Shelf life: 1 year.

Indications for Use

Indicated for patients recovering from general anesthesia in the PACU to scavenge waste anesthetic gases and provide supplemental oxygen.

Regulatory Classification

Identification

A gas-scavenging apparatus is a device intended to collect excess anesthetic, analgesic, or trace gases or vapors from a patient's breathing system, ventilator, or extracorporeal pump-oxygenator, and to conduct these gases out of the area by means of an exhaust system.

### Predicate Device

This submission demonstrates substantial equivalence to the predicate device ISO-GARD ClearAir Mask - K123176

## Device Description

The ISO-Gard Mask system is an oxygen delivery mask that actively scavenges waste anesthetic gases (WAGS) exhaled by patients recovering from surgery in the Post-Anesthetic Care Unit (PACU). Vacuum/suction for scavenging of WAGS is provided by the institution's regulated vacuum source. The proposed device allows for the delivery of supplemental / therapeutic oxygen to patients to aid in their recovery while reducing the amount of patient expelled waste anesthetic agents released to the work environment of the healthcare workers. The mask can be used with or without suction / vacuum to function as a standard oxygen mask with an ETCO2 monitoring port.

## Indications for Use

The ISO-Gard® Mask is intended to be used to scavenge waste anesthetic gases from patients during recovery from general anesthesia and to provide supplemental oxygen.

The 1SO-Gard® Mask helps to reduce the amount of anesthetic agents released to the work environment of the healthcare worker.

## Patient Population

Patients recovering from general anesthesia in the PACU.

### Environments of use

The environment of use is - Post-operative Care Units (PACU) in hospital, sub-acute facilities.

## Contraindications

None

## Substantial Equivalence

The proposed device is substantially equivalent to the predicate devices:
