The phases of a volumetric capnogram, the shape and curve morphology, and measurements based on calculations derived from it can tell you an important story about:
On our ventilators, CO2 is measured with a CAPNOSTAT-5 mainstream CO2 sensor proximal to the patient's airway.
The CAPNOSTAT-5 sensor gives you precise measurements of end-tidal carbon dioxide (PetCO2), and a clear, accurate capnogram at all respiratory rates of up to 150 breaths per minute.
The volumetric capnogram window on the display shows exact quantitative information as a combination of proximal flow and proximal CO2 data such as:
To allow a more comprehensive analysis of the patient condition, a 72-hour trend (or 96-hour with HAMILTON-G5/S1) is available for:
To make your life easier, Hamilton Medical ventilators offer an overview of all relevant CO2-related values in the Monitoring CO2 window.

The volumetric capnogram has been used successfully in the measurement of anatomical dead space, pulmonary capillary perfusion, and ventilatory efficiency (
Calculations derived from volumetric capnography are useful for identifying pulmonary embolism at the bedside (
Volumetric capnography measurements of physiologic dead-space-to-tidal-volume ratio in mechanically ventilated patients with ARDS are as accurate as those obtained by metabolic monitor technique (
The expiratory capnogram is an effort-independent, rapid, noninvasive measurement that indicates significant bronchospasm in adult patients with asthma (
Volumetric capnography provides valuable insights into the physiology of lung collapse and recruitment in a noninvasive, real-time manner, and thus lends itself to monitoring cyclic recruitment maneuvers at the bedside (
We offer original consumables for adult, pediatric, and neonatal patients. You can choose between reusable and single-use products, according to your institutional policies.
Volumetric capnography is available as an option on the HAMILTON-C6, the HAMILTON-G5, the HAMILTON-C3, and the HAMILTON-C1/T1, and as a standard feature on the HAMILTON-S1.
