Handheld anaesthetic-gas monitoring for veterinary surgery — N2O and five agents plus EtCO2 and SpO2 in one 5.5-inch 720P unit.
Hero Media
Product Overview
The IWA-HM320 is a handheld veterinary monitor that combines anaesthetic gas analysis, end-tidal CO2 and pulse oximetry in a single 900 g unit. It identifies and measures nitrous oxide (N2O) and five volatile agents — sevoflurane, isoflurane, enflurane, halothane and desflurane — alongside EtCO2, FiCO2, SpO2, pulse rate and respiration rate.
By bringing agent analysis into a handheld form factor, the IWA-HM320 lets practices monitor anaesthetic depth and ventilation without a benchtop gas bench. Live waveforms and numeric values are shown on a 5.5-inch 720P display, with an 8000 mAh battery for more than 8 hours of operation and 400-hour trend storage.
Key Features
- Integrated anaesthetic gas analysis: N2O and five agents (SEV, ISO, ENF, HAL, DES)

- SpO2, pulse rate and respiration rate on the same handheld unit
- 5.5-inch 720P (1280 × 720) colour display with waveforms and numeric values
- Handheld 900 g form factor — agent monitoring without a benchtop bench
- 8000 mAh battery for over 8 hours of operation per charge
- Short-term trends (15 min / 1 h / 6 h) and long-term storage up to 400 hours
- Battery-status indicator, audible-and-visual alarms and SpO2 pulse tone
- USB 2.0 data interface; universal 90–260 V AC charging
- Bilingual Chinese / English interface

Clinical Applications
- Intra-operative anaesthesia monitoring of agent concentration, ventilation and oxygenation in canine, feline and equine patients
- Confirmation of inspired and expired agent levels during inhalation anaesthesia
- Recovery-area monitoring of CO2 and SpO2 after gas anaesthesia
- Mobile and referral anaesthesia where a benchtop agent analyser is unavailable
- Teaching and clinical audit of anaesthetic gas delivery
Workflow & Setup Notes
- Connect the mainstream CO2 / agent sensor in-line at the airway and attach the SpO2 clip sensor.
- The monitor identifies the volatile agent in use and displays inspired and end-tidal concentrations with waveforms.
- Review short-term trends (15 min / 1 h / 6 h); long-term data is retained up to 400 hours.
- Charge from any 90–260 V mains via the charging stand between cases.
- Set agent, CO2, SpO2 and respiration alarm thresholds per anaesthetic protocol.

- All-day battery: 8000 mAh for over 8 hours of operation, with 400-hour trend storage.
- Mobile by design: brings agent monitoring to referral, field and multi-room practice.
Warranty & Support
Manufacturer warranty period [TBC]. Training, maintenance and servicing are provided through the local distributor. Sensors and CO2 / agent airway adapters are wear items.
Frequently Asked Questions
- Which anaesthetic gases does the IWA-HM320 measure?
- Nitrous oxide (N2O) and five volatile agents: sevoflurane (SEV), isoflurane (ISO), enflurane (ENF), halothane (HAL) and desflurane (DES), alongside EtCO2, FiCO2, SpO2, pulse and respiration rate.
- How does it differ from the IWA-HM310?
- The IWA-HM310 measures SpO2, pulse, respiration and EtCO2. The IWA-HM320 adds full anaesthetic gas analysis (N2O and five agents) on the same handheld platform.
- Does it need a separate gas analyser?
- No. Agent analysis is integrated into the handheld unit, so no benchtop gas bench is required.
- How long does the battery last?
- The built-in 8000 mAh battery supports more than 8 hours of operation and charges from any 90–260 V mains.
- Which species does it support?
- Canine, feline, equine and other patients undergoing inhalation anaesthesia. Select an SpO2 sensor site appropriate to the patient.
