Replacing printer paper Cleaning the printer Ordering the printer and printer accessories Printer specifications Print indicator screen icon The TuffSat is a small, durable, portable pulse oximeter that operates on battery power. These items are included with the oximeter:. For information on ordering and using this printer with the TuffSat, see the appendix: Printer Features and Use.
The TuffSat is designed specifically for spot-checking arterial oxygen saturation SpO 2 and pulse rate. This easy-to-use oximeter is ideal for use in the environments listed below:. The TuffSat oximeter is not intended for continuous monitoring. It has no alarms audible or visual and no user-definable parameters. The PI r pulsatile value indicates the strength of the pulse signal at the sensor site: the higher the PI r value, the stronger the pulse signal.
A strong pulse signal increases the validity of SpO 2 and pulse rate data. PI r is a relative value that varies from patient to patient. Clinicians can use the PI r value to compare the strength of the pulse signal at different sites on a patient in order to locate the best site for the sensor the site with the strongest pulse signal. The TruTrak data sampling system, patented by Datex-Ohmeda, enables the TuffSat oximeter to calculate SpO 2 many times each second through advanced statistical data processing.
While other oximeters calculate only at the peak and trough of each waveform, the TuffSat assesses SpO 2 continuously. The TruTrak data sampling system provides reliable readings during times of low perfusion, motion, or electrical interference. The result is a highly reliable level of oximetry performance.
The TuffSat oximeter uses a two-wavelength pulsatile system—red and infrared light—to distinguish between oxygenated O 2 Hb and reduced HHb hemoglobin, each of which absorbs different amounts of light emitted from the oximeter sensor.
The SpO 2 and pulse rate are determined by the oximeter through sensor signal processing and microprocessor calculations. The two light wavelengths generated by the sensor light source the red and infrared LEDs pass through the tissue at the sensor site. The light is partially absorbed and modulated as it passes through the tissue. The pulsatile portion of the incoming signal is used to detect and isolate the attenuation of light energy due to arterial blood flow. The oximeter uses this information to calculate the relative percentage of O 2 Hb and HHb.
The photodetector sends the electronic signal, which contains the light intensity information, to the oximeter. Datex-Ohmeda pulse oximeters use two wavelength ranges, nm to nm and nm to nm, both with an average power of less than 1 mW.
These wavelengths are used to calculate the presence of oxyhemoglobin O 2 Hb and reduced hemoglobin HHb. The calculation of SpO 2 assumes 1. Appreciable variation from these values will influence SpO 2 accuracy. Two different methods of calibration are currently used by manufacturers of pulse oximeters: fractional and functional.
Important : The TuffSat pulse oximeter uses the functional calibration method. The user cannot change the calibration method to fractional. Functional saturation is represented mathematically as the percentage of hemoglobin capable of carrying oxygen that is carrying oxygen. The functional calibration is obtained by multiplying the fractional SpO 2 by a value of 1. The circuit board contains all the circuitry for the TuffSat oximeter. The functions performed by this board are illustrated below.
Warnings and cautions associated with following safe practices while using the oximeter appear throughout this manual. Warning : Power off the oximeter before cleaning or servicing. Warning : Do not use the monitor in the presence of any flammable anesthetic mixture.
Warning : It is possible for any device to malfunction; therefore, always verify unusual data by performing a formal patient assessment. Warning : Do not use the oximeter if it fails to function as described or if the validity of data is questionable. Refer to the appropriate sections of this manual to identify and correct the malfunction.
Warning : To prevent erroneous readings, do not use an inflated blood pressure cuff or arterial blood pressure measurement device on the same limb as the oximeter sensor.
Warning : Conditions that may cause inaccurate readings include interfering substances, excessive ambient light, electrical interference, excessive motion, low perfusion, low signal strength, incorrect sensor placement, poor sensor fit, and movement of the sensor on the patient.
Warning : To protect against injury and equipment damage from leaking batteries, remove the batteries when the oximeter is not to be used for some time.
Warning : The TuffSat oximeter is not intended for continuous monitoring. Warning : Never test or perform maintenance on the oximeter while using it to monitor a patient. Warning : When the battery becomes depleted, the oximeter shuts off. No alarm sounds. Warning : The correct use of the oximeter is to measure only arterial oxygen saturation SpO 2 , pulse rate, and the Relative Perfusion Index PI r pulsatile value.
