Principle of operation General Description

Symbols
Principle of operation
CO2
TIDAL WAVE Spuses the CAPNOSTAT CO2sensor to measure CO2by using the infrared absorbtion technique,
which has endured and evolved in the clinical setting for over two decades and remains the most popular and
versatile technique today.
The principle is based on the fact that CO2molecules absorb infrared (IR) light energy of specific wavelengths,
with the amount of energy absorbed being directly related to the CO2concentration. When an IR beam is passed
through a gas sample containing CO2, the electronic signal from the photodetector(which measures the remaining
light energy) can be obtained. This signal is then compared to the energy of the IR source and calibrated to
accurately reflect CO2concentration in the sample. To calibrate, the photodetector’s response to a known
concentration of CO2is stored at the factory in the monitor’s memory. A reference channel accounts for optical
changes in the sensor, allowing the system to remain in calibration without user intervention.
SpO2
The TIDAL WAVE Sp determines oxygen saturation using sensors that contain red and infrared (660 and 940
nanometer) light sources, called lightemitting diodes (LEDs). The light energy from each LED is beamed through
a tissue sample—a pulsating vascular bed such as the patient’s finger or toe. The remaining light energy not
absorbed by the tissue sample reaches a photodiode light receptor in the sensor. Oxygen saturated blood absorbs

different amounts of light at each wavelength as compared to desaturated blood. Therefore, the amount
of light absorbed by the blood in each pulse can be used to calculate oxygen saturation.
The TIDAL WAVE Sp is calibrated to display “functional”saturation. This differs from the “fractional”
saturation value displayed by most co-oximeters. Functional saturation is defined as:
This can be considered to represent the amount of oxyhemoglobin as a percentage of the hemoglobin that
can be oxygenated. Dysfunctional hemoglobins (COHb and METHb) are not included in the
measurement of functional saturation.
Pulse Rate is calculated by measuring the time interval between peaks of the infrared light waveform.
The inverse of this measurement is displayed as pulse rate.
The oxygen saturation and pulse rate values are updated once each second. Presence of a pulse is
indicated visibly by a plethysmogram graphic display and audibly by a “beep,”when configured.
The TIDAL WAVE Sp must be used in conjunction with SuperBright™Sensors. See “Accessories”on
page 69 for a list of available sensors and accessories.
Functional Saturation = HbO2
100 - (COHb + METHb)
HbO2 = Fractional Oxyhemoglobin
COHb = Carboxyhemoglobin
METHb = Methemoglobin

Section 2 Safety
For maximum patient and operator safety, you must follow the following warnings and cautions.
•Explosion Hazard: DO NOT use TIDAL WAVE Sp in the presence of flammable anesthetics. Use
of this instrument in such an environment may present an explosion hazard.
•Electrical Shock Hazard: Always turn TIDAL WAVE Sp off and remove any external devices
before cleaning it. Refer servicing to qualified service personnel.
•Failure of Operation: If the monitor fails to respond as described, do not use it until the situation
has been corrected by qualified personnel.
•Do not operate TIDAL WAVE Sp if it appears to have been dropped or damaged.
•Do not operate TIDAL WAVE Sp or its accessories when it is wet due to spills or condensation.
•Never sterilize or immerse the monitor, sensor or accessories in liquids.
•The monitor does not alert for NO RESPIRATION if the airway adapter is removed from the
CAPNOSTAT CO2sensor.
•Verify the “No Resp Timer”setting prior to use.
•Do not position any sensor cable in a way that may cause entanglement or strangulation.
•The TIDAL WAVE Sp is not intended to be used as a primary diagnostic apnea monitor and/or
recording device.
•Patient Safety: Care should be exercised to assure continued peripheral perfusion distal to the
SpO2sensor site after application.
•Inspect the SpO2sensor site often for adequate circulation - at least once every four hours. When
applying sensors take note of patient’s physiological condition. For example, burn patients may
exhibit more sensitivity to heat and pressure and therefore additional consideration such as more
frequent site checks may be appropriate.
•Data Validity: As with all pulse oximeters, inaccurate SpO2and Pulse Rate values maybe caused by:
- Incorrect application or use of sensor;
- Significant levels of dysfunctional hemoglobin; carboxyhemoglobin or methemoglobin;
- Significant levels of indocyanine green, methylene blue, or other intravascular dyes;
- Exposure to excessive illumination such as surgical lamps-especially those with a
xenon light source, or direct sunlight;
- Excessive patient movement;
- Venous pulsations;
- Electrosurgical interference.
•The external battery charger should NOT be used to recharge the battery nearor in close proximity
to patients and/or other medical equipment in operation. It is intended for use in service areas only
(i.e. nurses station, biomed lab, etc.).
WARNINGS
Indicates a potentially harmful condition that can lead to personal injury.

•If a Single Patient Use Sampling Adapter becomes occluded, replace and discard the adapter.
•It is recommended that the CAPNOSTAT CO2sensor be removed from the circuit whenever an
aerosolized medication is delivered. This is due to the increased viscosity of the medications
which may contaminate the sensor windows, causing the sensor to fail prematurely.
•Where electromagnetic devices (i.e. electrocautery) are used, patient monitoring may be
interrupted due to electromagnetic interference. Electromagnetic fields up to 3V/m will not
adversely affect system performance.
•Refer servicing to qualified personnel.
•The TIDAL WAVE Sp monitor is intended for operation with Novametrix Single Patient Use
airway adapters.
•Operating the TIDAL WAVE Sp below 50°F (10°C) will result in longer warm-up time and reduce
battery life.
•Components of this product and its associated accessories which have patient contact are free of
latex.
•Certain rebreathing circuits, or the presence of artifacts such as cardiogenic oscillations, may
cause TIDAL WAVE Sp to react to non-respiratory CO2fluctuations as if they were breaths. This
condition affects only the RESP numerical displays; the capnogram display continues to provide
an accurate picture of the CO2waveform.
•After the life cycle of our equipment and all accessories has been met, disposal of the equipment
