GHM-CA20M Capnograph | Mainstream EtCO2 Monitor with SpO2 & 8‑Hour Battery #

Mainstream capnograph with EtCO2, respiration rate, SpO2, and pulse rate monitoring. Audible/visual alarms, self‑calibration, 8‑hour battery, and high‑altitude capability. Ideal for ICU, ED, OR, and respiratory care.

The Global Healthcare Medical GHM-CA20M Capnograph is a compact, handheld mainstream capnograph designed for continuous, real‑time monitoring of end‑tidal carbon dioxide (EtCO₂) , airway respiration rate (AwRR) , blood oxygen saturation (SpO₂) , and pulse rate (PR) in a single integrated device. Using advanced mainstream measurement technology, the device places the CO₂ sensor directly in the patient's breathing circuit via an airway adapter and breathing tube, providing accurate, real‑time measurements at the airway.

This versatile monitoring solution is applicable for adult, pediatric, and infant patients in emergency departments, ICUs, operating rooms, respiratory departments, and pre‑hospital emergency transfer. With its compact design, rechargeable battery providing up to 8 hours of continuous use, and comprehensive alarm system, the GHM-CA20M is an essential tool for clinicians managing ventilated and non‑ventilated patients alike.

This device is intended for use by healthcare professionals in clinical settings. It is not a substitute for professional medical diagnosis.

Key Features

🫁 Mainstream EtCO₂ & Respiration Rate Monitoring

The GHM-CA20M adopts mainstream measurement technology to continuously measure end‑tidal carbon dioxide (EtCO₂) and airway respiration rate (AwRR). This enables clinicians to:

• Monitor pulmonary ventilation function

• Assess circulation and pulmonary blood flow

• Indirectly evaluate alveolar ventilation

EtCO₂ Specifications:

• Measurement range: 0 – 150 mmHg

• Resolution: 1 mmHg

• Accuracy: 0–40 mmHg: ±2 mmHg; 41–70 mmHg: ±5% of readings; 71–100 mmHg: ±8% of readings; 101–150 mmHg: ±10% of readings

Respiration Rate Specifications:

• Measurement range: 2 – 150 rpm

🩸 Integrated SpO₂ & Pulse Rate Monitoring

In addition to capnography, the GHM-CA20M measures blood oxygen saturation (SpO₂) and pulse rate (PR) in a single, integrated device, providing comprehensive respiratory and hemodynamic assessment without the need for separate monitors.

🚨 Comprehensive Audible & Visual Alarms

Patient safety is paramount with the GHM-CA20M's advanced alarm system:

• Audible and visual alarms with silencing function

• Adjustable alarm limits for all parameters

• Over‑limit alarms for EtCO₂, respiration rate, SpO₂, and pulse rate

• Low battery alarm

• "Adapter off" prompt to ensure proper airway adapter connection

🔬 Self‑Calibration & Environmental Compensation

The GHM-CA20M allows users to calibrate the device independently, ensuring ongoing measurement accuracy. It also features built‑in atmospheric pressure and temperature compensation functions, maintaining reliable performance across varying clinical environments—including high altitude areas.

🔋 Long‑Lasting Rechargeable Battery

Powered by a rechargeable lithium battery, the GHM-CA20M provides up to 8 hours of continuous use, ensuring uninterrupted monitoring during transport, emergency procedures, and power outages. The device also features a low battery alarm to alert clinicians before power runs out.

💾 Data Storage & Transmission

The GHM-CA20M includes a reserved data storage and transmission function module, enabling future expansion for data management and integration with hospital information systems.
