Flagship mainstream capnography at the airway — real-time EtCO2 with a rechargeable 10-hour lithium battery and optional Bluetooth.
Hero Media
Product Overview
The IWA-CAPNO-M is the flagship configuration of the mainstream capnograph range. It measures, displays and monitors expired CO2 partial pressure and respiration rate during anaesthesia, recovery and respiratory therapy, with the sensor mounted directly on an in-line airway adapter for measurement at the airway and no sampling line.
The flagship configuration is powered by a high-capacity 1200 mAh rechargeable lithium battery that delivers 10 hours of operation and recharges in about 1.5 hours, removing the running cost of disposable cells. As a fully solid-state device it shows a real-time EtCO2 waveform within 4 seconds of power-up, needs no user calibration, and offers optional Bluetooth data transfer — all in an under-65 g sensor with IPX4 protection.
Key Features
- Mainstream measurement at the airway — no sampling line, no water trap
- Rechargeable 1200 mAh lithium battery — 10 hours of operation, ~1.5-hour recharge
- Real-time EtCO2 waveform displayed within 4 seconds of power-up
- Fully solid-state design — rugged and reliable in demanding environments
- No user calibration required
- Optional Bluetooth data transfer for record-keeping and remote display
- 1.4-inch colour TFT display with EtCO2 value, respiration rate and capnogram
- Comprehensive audible-and-visual alarms: adapter check, apnoea, low battery, EtCO2 and RR limits
- Under 65 g sensor head adds minimal weight to the breathing circuit
- IPX4 ingress protection; adult adapter dead space ≤6 ml, paediatric/neonatal ≤1 ml

Clinical Applications
- Capnography during anaesthesia in canine, feline and equine patients
- Confirmation of endotracheal tube placement and apnoea detection
- Recovery and respiratory-therapy monitoring of ventilation
- Emergency and critical-care use during resuscitation
- High-volume practice and transport where a rechargeable battery lowers running cost
Workflow & Setup Notes
- Fit the airway adapter in-line between the endotracheal tube and breathing circuit, then mount the sensor head on the adapter.
- Select the adult (≤6 ml) or paediatric/neonatal (≤1 ml) adapter to match patient size and minimise dead space.
- A real-time EtCO2 waveform appears within 4 seconds; no warm-up calibration is required.
- Recharge the lithium battery between sessions — about 1.5 hours for a full charge.
- Pair the optional Bluetooth link for record-keeping or remote display where required.

Frequently Asked Questions
- How does the IWA-CAPNO-M differ from the IWA-CAPNO-E and -P?
- All three are mainstream capnographs sharing the same sensor performance. The flagship IWA-CAPNO-M uses a rechargeable 1200 mAh lithium battery (10 hours, ~1.5-hour recharge) and offers optional Bluetooth, whereas the IWA-CAPNO-E runs on AAA cells.
- How long does the battery last and how is it charged?
- The rechargeable 1200 mAh lithium battery delivers about 10 hours of use and recharges from 0–100% in roughly 1.5 hours.
- Does the IWA-CAPNO-M need calibration?
- No. It is a fully solid-state device requiring no user calibration, showing a real-time EtCO2 waveform within 4 seconds of power-up.
- Which airway adapter should I use?
- Use the adult adapter (dead space ≤6 ml) for larger patients and the paediatric/neonatal adapter (≤1 ml) for small patients to minimise added dead space.
- Which species does it support?
- Canine, feline, equine and other intubated or mask-ventilated patients. Match the airway adapter to patient size.
