1 Introduction 1.1 Intended Use The CapnoTrue® CO2 /SpO2 Monitor is intended to provide continuous monitoring of end-tidal CO2 concentration (EtCO2), inspired CO2 concentration (FiCO2), functional arterial oxygen saturation (SpO2), respiration rate (RR) and pulse rate (PR) of adult, paediatric infant and neonatal patients. The CO2 measurement can be performed either with the mainstream method using the CapnoTrue®AMP or with the sidestream method using the CapnoTrue®ASP. It may be used in hospital, hospital type facilities, operating suites, intensive care units, emergency medicine/emergency transport as well as in the home care environment. The CapnoTrue® CO2 /SpO2 Monitor is not intended to be used as the only means of monitoring a patient. It shall always be used in combination with other vital sign monitoring devices and/or professional human judgments of a patient’s condition. The CapnoTrue® is intended to be used by trained and authorized health care professionals only. 1.2 Warnings Adhere to the following warnings for safe operation of the CapnoTrue®AMP mainstream CO2 /SpO2 Monitor and the CapnoTrue®ASP sidestream CO2 /SpO2 Monitor. For CapnoTrue® in General: Warning: The monitor is to be operated only by trained personnel and is for attended monitoring only. Warning: Do not make any clinical judgments based solely on the CapnoTrue®. The monitor is intended only as an adjunct in patient assessment. It must be used in conjunction with clinical signs and symptoms. The interpretation of the measurement values should be done only by trained health care professionals. Warning: The monitor should only be used for the purpose and in the manner described in this manual. Warning: Explosion hazard. Do not use the monitor in the presence of flammable anaesthetic mixtures with air, oxygen, or nitrous oxide.
Warning: Routinely monitor the patient to make sure that the CapnoTrue® is functioning correctly and the SpO2 sensor, the mainstream IRMA™ CO2 analyzer and the CO2 sidestream sampling configuration are correctly placed. Warning: Do not place the monitor in any position that might cause it to fall on to the patient. Warning: Certain environmental and physiological conditions, medical procedures, sensor application errors and external agents may interfere with the monitor‘s ability to detect and display accurate measurements. (Chapter 9 provides information on possible interferences) Warning: For the SpO2 measurement, the monitor uses red and infrared light with specific fixed wavelengths. Consider that these wavelengths might influence diagnostic parameters of other optical applications. The specifications of the wavelengths used are listed in the ‘Instructions for Use’ of the specific sensor. Warning: The monitor detects respiratory effort via changes in CO2 concentration of exhaled air; therefore, the CO2 measurement can be used to detect apnoea. The device however is unable to discriminate between a patient not breathing and a sensor that is disconnected from the patient circuit. Always monitor and set alarms for SpO2 when using the CapnoTrue® to monitor respiratory function. Warning: If you are uncertain about the accuracy of any measurement, check the patient’s vital signs by alternate means; then make sure the monitor is functioning correctly. Warning: The use of accessories, sensors, and cables other than those specified may result in increased electromagnetic emission and/or create invalid readings of the monitor. Warning: In high ambient light conditions it is required to shield the SpO2 sensor application site with opaque material. Too much ambient light may result in inaccurate measurements. Warning: Check all alarm settings and auditory alarm before use of the monitor. Warning: Do not silence the audible alarm function, or decrease the audible alarm volume if patient safety could be compromised.

2 Theory of operation 2.1 CO2 measurement Principle The measurement of CO2 in gas mixtures with the CapnoTrue® is based on the fact that different gases absorb infrared light at specific wavelengths. The absorption spectra for CO2, N2O and different anaesthetic agents are shown in Figure 1. The CO2 analyzer of the CapnoTrue® uses the absorption peak at 4.2μm to determine the CO2 concentration in the gas. Two additional wavelengths beside this absorption peak are used as reference. To measure the absorption of light at these wavelengths, a broadband infrared radiation source is
Capnogram A capnogram is a graph representing the CO2 concentration in respiratory gasses plotted against time. The capnogram waveform is typically divided into 4 phases (Bhavani-Shankar & Philip, 2000). In the waveform below the inspiration (phase 0) is plotted in blue and the expiration (phase I - III) in red.

used. The light transmitted from the infrared source passes through the gas sample and is then filtered using a set of narrow optical band pass filters. The individual filters are mounted in a rapidly rotating filter wheel that intersects the light path before the light reaches the infrared detector. The infrared detector detects the portion of the light that is not absorbed by the gas. The amplitude of the detector output is an inverse function of the gas concentration. Thus, at a concentration of zero, the amplitude is at its maximum.
Phase I: Baseline (FiCO2) Phase II: Positive expiration slope (alveolar gas) Phase III: Alveolar plateau (EtCO2) Phase 0: Inspiration A capnogram provides valuable information regarding the health situation of patients in respiratory distress.

the sidestream method. In both cases the measurement principle is very similar (infrared spectroscopy) the position of the sensor in the measurement setup however differs. In mainstream capnography an airway adapter is, for example, inserted between the endotracheal tube and the Y-piece of the breathing circuit. The airway adapter has an optical window over which the infrared mainstream CO2 sensor is positioned. The respiratory CO2 measurements are obtained by continuously measuring the infrared light absorption, in the gas flow, through the optical windows. For sidestream capnography a sampling line is connected to an endotracheal tube with the help of a sidestream airway adapter or directly from the nose via a nasal prong. Gas samples are continuously taken from the patient at a constant flow rate (CapnoTrue®ASP has a suction rate of 50ml/min) and transferred to the infrared CO2 sensor incorporated in the capnograph. The CO2 measurement is taken within the device and after measurement the waste gas is exhausted through the gas outlet. Typically water traps and bacteria filters are positioned between the sampling line and the device inlet to avoid damage to the device. 2.2 SpO2 measurement SpO2 measurement is performed in transmission mode. The SpO2 sensor consists of emitters which pass red and infrared light through peripheral sites such as a finger, toe or ear to a light-sensitive detector. For both wavelengths the change in absorption is continuously measured. In this way the pulsatile signal due to the arterial blood alone is extracted, excluding the offset due to absorption by venous blood, skin, bone, muscle and fat. This signal is used to determine the functional arterial oxygen saturation (SpO2) based on the fact that the amount of absorbed infrared light and red light is different for oxygenated haemoglobin (HbO2) and deoxygenated haemoglobin (Hb). The amount of red and infrared light received is compared and the percent of haemoglobin molecules bound with oxygen molecules calculated:
SPO2=
HbO2 HbO2 + Hb
These measurement values are continuously displayed as a waveform (plethysmogram) and also used to determine the pulse rate. Note that the pulse oximeter equipment is calibrated to display the functional oxygen saturation. Certain physiological conditions, medical procedures, and external agents may interfere with the monitor’s ability to detect and display accurate SpO2 measurements (see chapter 9.2 for detailed information). 3 Product overview 3.1 Available models Mainstream Capnograph/Pulse Oximeter – CapnoTrue®AMP The CapnoTrue®AMP is used together with an IRMA™ CO2 analyzer, an IRMA™ airway adapter and an application appropriate SpO2 sensor.

Sidestream Capnograph/Pulse Oximeter – CapnoTrue®ASP The CapnoTrue®ASP monitor is used together with a Nomo Adapter, a suitable sampling line configuration (e.g. sampling line, airway adapter, nasal/oral sampling) and an application appropriate SpO2 sensor. Power is delivered via either the provided power supply, a rechargeable Li-ion battery or 4 x AA batteries. Sidestream CO2 monitoring is performed with the ISA™ CO2 analyzer incorporated in the CapnoTrue®ASP. Together with the Nomo technology that removes water from the sampled gas, the ISA™ CO2 analyzer with integrated sampling pump delivers highest performance in ultra-compact format. Key features of CapnoTrue®ASP: • Warm-up time < 10s • Specially designed for all applications using low flow sampling (50 ml/min); from adults to neonates • For intubated and non-intubated patients • Nomo technology incorporated in the Nomo Adapter to remove water and water vapour from the sampling line. • Hydrophobic bacterial filter incorporated in the Nomo Adapter to reduce the potential for water intrusion and cross contamination. • Maintenance and calibration-free technology • Wide range of high-quality SpO2 sensors available • 2 years warranty 3.2 Mainstream Capnography Accessories 3.2.1 IRMA™ CO2 analyzer The IRMA™ CO2 analyzer is an ultra compact measurement device for mainstream CO2 measurement with the CapnoTrue®AMP. As all necessary calibration constants are stored within each IRMA™ CO2 analyzer, the analyzer can be replaced without the need for recalibration.
Figure 3: IRMA™ CO2 analyzer with airway adapter
To perform gas measurements, the IRMA™ CO2 analyzer requires an airway adapter. The IRMA™ CO2 analyzer connects in place on top of the IRMA™ airway adapter. This airway adapter is, for example, inserted between the endotracheal tube and the Y-piece of the breathing circuit. Respiratory CO2 measurements are obtained by continuously measuring the infrared light absorption, through optical XTP™ windows, in the gas flow through the adapter. 3.2.2 IRMA™ airway adapter The IRMA™ airway adapter is designed as a singlepatient-use disposable product and is available as: • IRMA™ airway adapter (adult/paediatric) for patients over 1 year of age or 10kg in weight. • IRMA™ airway adapter (infant) for patients up to 1 year of age or 10kg in weight. The IRMA™ airway adapter (infant) has specially designed connectors for minimizing the dead space and can be used on very small patients.
The analyzer has a rugged mechanical design providing reliable shock resistance.

As the airway adapter is positioned directly in the airway, its performance can be affected by water vapour, patient secretions or nebulised medications that can accumulate on the adapter’s windows.
The Nomo Adapter contains an unique water separation section and a hydrophobic bacterial filter to protect the ISA™ CO2 analyzer against water intrusion and cross contamination.
The water vapour can condense on the surface of the adapter windows in the format of small discrete water droplets. This condensation can affect light absorption through the windows, thus affecting the precision of the measurement. The XTP™ windows of the IRMA™ airway adapter therefore have special features that prevent a decrease in performance when vapour is present. Using the latest advances in material technology they are designed to provide a window minimizing the impact of water vapour on light transmission. For optimal results, the airway adapter shall not be placed between an endotracheal tube and an elbow, as this may allow patients secretions to block the adapter window. 3.3 Sidestream Capnography Accessories Sidestream CO2 measurement is performed by continuously removing a gas sample at a flow of 50ml/min from the respiratory circuit and analyzing it within the sidestream ISA™ CO2 analyzer incorporated in the CapnoTrue®ASP. To transport the gas sample from the patient to the device, a sampling line configuration is required. A sampling line configuration consists of a Nomo Adapter connected to a sampling line with an appropriate patient interface for sampling gas, e.g. a nasal cannula, respiratory mask or the Y-piece of an intubated patient. 3.3.1 Nomo Adapter The gas sample coming from the sampling line is fed through the Nomo Adapter to the CapnoTrue®ASP. The Nomo Adapter is specifically designed for 50ml/ min low sampling flow applications. It has a very low dead space that results in an ultra-fast rise time, making CO2 measurement possible, even at high respiratory rates. The CapnoTrue®ASP application therefore ranges from neonates to adults.
Figure 5: Nomo Adapter
No condensing water: Because of condensing water within the connected sampling line, droplets can potentially result in occlusion of the sampling system and interfere with the CO2 measurement. To prevent this situation the Nomo Adapter incorporates a unique water separation section, the NOMO section. This section is made of a special polymer and a hydrophobic bacteria filter and removes water vapour and aspired or condensed water. Water and water vapour passes through the membrane-like surface of the sampling line and evaporates into the surrounding air, while leaving CO2 unaffected. Bacterial filter: To protect the sidestream ISA™ CO2 analyzer against cross contamination, the Nomo Adapter includes a filter with bacterial filter efficiency of ≥99.9980%. It is important to be aware that secretion and nebulised medication may be absorbed by the surface of the bacteria filter, and may block the Nomo Adapter. Replacement of Nomo Adapter: The Nomo Adapter is reusable as the Nomo technology allows up to two weeks of continuous monitoring with high moisture containing breathing gases. Warning: The Nomo Adapter is reusable. It only needs to be replaced if occluded. Replace the Nomo Adapter if “Sampling system occlusion !” is displayed by the CapnoTrue®ASP whilst only the Nomo Adapter is connected.

3.3.2 Sidestream sampling line, airway adapter and other patient interfaces Sampling with intubated patient Sampling with intubated patients is typically performed with an appropriate sidestream airway adapter connected to the Nomo Adapter with a disposable sampling line. The sidestream airway adapter is designed as a single-patient-use disposable product and is available in different sizes ranging from adults through to neonates.
Sampling with non-intubated patient Sampling with non-intubated patients is typically performed with a nasal or oral sampling configuration. This sampling assembly is directly connected to the nose or mouth with a cannula. For further instructions, warnings and precautions refer to the ‘Instructions for Use’ provided with the selected sampling system assembly. Note: Our sampling line configurations are continuously updated; please contact bluepoint MEDICAL for detailed information. Specific patient sampling line configurations and interfaces are available upon request. 3.4 SpO2 Sensors Bluepoint MEDICAL supplies a large variety of disposable and reusable SpO2 sensors for use with the CapnoTrue®.
