Resumen del manual
When a finger is inserted into the sensor’s rubber cushion, the SpO2 value automatically displays. The pulse bar graph displays the user’s pulse beat, and the bar graph’s height shows pulse strength. The oximeter, which is powered by two AAA batteries, features a low- battery indicator and powers off automatically in eight seconds when not in use. Product Accessories (Included) 1. One lanyard 2. Two AAA batteries 3. One protective cover 4. One operator manual Principle of Measurement Two beams of different wavelength (660 nm glow and 940 nm near infrared light) are focused onto a human nail tip through a clamping finger-type sensor. A measured signal obtained by a photosensitive element, through processes of electronic circuits and microprocessor, will be shown on the oximeter’s display. Principle of Operation Diagram See illustration and descriptions below. 1 Red and Infrared Emission Tube 2 Red and Infrared Receipt Tube INTENDED USE The intended use of the OxyCheck Fingertip Pulse Oximeter is the measurement and display of the functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) of adults and pediatric users in hospital, ambulatory, home, and EMS (Emergency Medical Service) environments. The Pulse Oximeter is intended for spot-checking these levels. Contraindications ( WARNINGS): • If you do not understand any part of these instructions, contact a healthcare professional for direction in the use of this product. • This device is not intended for continuous monitoring. • Do not use this device in an explosive atmosphere. • Do not use this device in an MRI or CT environment. INACCURATE MEASUREMENTS MAY BE CAUSED BY THE FOLLOWING: • Autoclaving, ethylene oxide sterilizing, or immersing the device in liquid • Significant levels of dysfunctional hemoglobins (such as carbonxy- hemoglobin or methemoglobin) • Intravascular dyes such as indocyanine green or methylene blue • High ambient light — shield the sensor area (with a surgical towel, or direct sunlight, for example) if necessary • Excessive user movement • High-frequency electrosurgical interference • Venous pulsations • Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line • User hypotension, severe vasoconstriction, severe anemia, or hypothermia • User cardiac arrest or shock • Improper finger placement, e.g. fingernail not facing upward • Fingernail polish or false fingernails. SAFETY — PRECAUTIONS FOR USE WARNING: Indicates a potential hazard situation or unsafe practice that, if not avoided, could result in death or serious injury. WARNING statements follow: Before use, carefully read the manual. The pulse oximeter has no alarms. Do not use the pulse oximeter in situations where alarms are required. It is not for continuous monitoring. The pulse oximeter is intended only as an adjunct in user assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms. CAUTION: Indicates a potential hazard or unsafe practice that, if not avoided, could result in moderate or minor personal injury. CAUTION statements follow: Check the pulse oximeter sensor application site frequently to determine the positioning of the sensor and circulation and skin sensitivity of the user. Do not stretch the adhesive tape while applying the pulse oximeter sensor. This may cause inaccurate readings or skin blisters. Prolonged use or the user’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours. s NOTICE: Indicates a potential hazard or unsafe practice that, if not avoided, could result in product/property damage. SETUP Battery Installation 1. Open battery compartment cover. 2. Install two AAA batteries in battery compartment, ensuring that polarities are correct. 3. Close battery compartment cover: Push cover horizontally along the arrow as shown at right. s NOTICE: • Ensure battery polarities are correct, or the device could be damaged. Lanyard Installation 1. Thread the thinner end of the lanyard through the oximeter loop. 2. Thread the thicker end of the lanyard through the threaded end, then pull it tightly. OPERATION INSTRUCTIONS 1. Use isopropyl alcohol to clean the test finger and the rubber inside the oximeter that touches the finger. 2. Place clamp over fingernail as shown at right; insert finger, fingernail up as shown. 3. Press button on front panel once. User’s finger and body must remain still during measurement. 4. See display: the SpO2 value automatically displays, the pulse bar graph displays the pulse rate, and the bar graph’s height shows the pulse strength. MAINTENANCE AND STORAGE s NOTICE: • This device contains no serviceable parts. Do not disassemble. • Remove the batteries if the oximeter will not be used for a long period of time. • Do not autoclave, sterilize with ethylene oxide, or immerse the device in liquid. • See SPECIF...
