Why is this important? this is important on soo many reason in levels, But first let me tell u what a pulse ox test is. Pulse oximetry is a non-invasive method allowing the monitoring of the oxygenation of a patient's hemoglobin.
A sensor is placed on a thin part of the patient's body, usually a fingertip or earlobe, or in the case of an infant, across a foot. Light of two different wavelengths is passed through the patient to a photodetector. The changing absorbance at each of the wavelengths is measured, allowing determination of the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) fingernail polish] With NIRS it is possible to measure both oxygenated and deoxygenated hemoglobin on a peripheral scale (possible on both brain and muscle).
A blood-oxygen monitor displays the percentage of arterial hemoglobin in the oxyhemoglobin configuration. Acceptable normal ranges for patients without COPD with a hypoxic drive problem are from 95 to 99 percent, those with a hypoxic drive problem would expect values to be between 88 to 94 percent, values of 100 percent can indicate carbon monoxide poisoning. For a patient breathing room air, at not far above sea level, an estimate of arterial pO2 can be made from the blood-oxygen monitor SpO2 reading.
Pulse oximetry is a particularly convenient noninvasive measurement method. Typically it utilizes a pair of small light-emitting diodes (LEDs) facing a photodiode through a translucent part of the patient's body, usually a fingertip or an earlobe. One LED is red, with wavelength of 660 nm, and the other is infrared, 905, 910, or 940 nm. Absorption at these wavelengths differs significantly between oxyhemoglobin and its deoxygenated form; therefore, the oxy/deoxyhemoglobin ratio can be calculated from the ratio of the absorption of the red and infrared light. The absorbance of oxyhemoglobin and deoxyhemoglobin is the same (isosbestic point) for the wavelengths of 590 and 805 nm; earlier equipment used these wavelengths for correction of hemoglobin concentration.
The monitored signal bounces in time with the heart beat because the arterial blood vessels expand and contract with each heartbeat. By examining only the varying part of the absorption spectrum (essentially, subtracting minimum absorption from peak absorption), a monitor can ignore other tissues or nail polish, (though black nail polish tends to distort readings) and discern only the absorption caused by arterial blood. Thus, detecting a pulse is essential to the operation of a pulse oximeter and it will not function if there is none.
A pulse oximeter (saturometer) is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram. It is often attached to a medical monitor so staff can see a patient's oxygenation at all times. Most monitors also display the heart rate. Portable, battery-operated pulse oximeters are also available for home blood-oxygen monitoring
A pulse oximeter is useful in any setting where a patient's oxygenation is unstable, including intensive care, operating, recovery, emergency and hospital ward settings, pilots in unpressurized aircraft, for assessment of any patient's oxygenation, and determining the effectiveness of or need for supplemental oxygen. Assessing a patient's need for oxygen is the most essential element to life; no human life thrives in the absence of oxygen (cellular or gross). Although a pulse oximeter is used to monitor oxygenation, it cannot determine the metabolism of oxygen, or the amount of oxygen being used by a patient. For this purpose, it is necessary to also measure carbon dioxide (CO2) levels. It is possible that it can also be used to detect abnormalities in ventilation. However, the use of a pulse oximeter to detect hypoventilation is impaired with the use of supplemental oxygen, as it is only when patients breathe room air that abnormalities in respiratory function can be detected reliably with its use. Therefore, the routine administration of supplemental oxygen may be unwarranted if the patient is able to maintain adequate oxygenation in room air, since it can result in hypoventilation going undetected.
Because of their simplicity and speed, pulse oximeters are of critical importance in emergency medicine and are also very useful for patients with respiratory or cardiac problems, especially COPD, or for diagnosis of some sleep disorders such as apnea and hypopnea. Portable battery-operated pulse oximeters are useful for pilots operating in a non-pressurized aircraft above 10,000 feet (12,500 feet in the U.S.) where supplemental oxygen is required. Prior to the oximeter's invention, many complicated blood tests needed to be performed. Portable pulse oximeters are also useful for mountain climbers and athletes whose oxygen levels may decrease at high altitudes or with exercise. Some portable pulse oximeters employ software that charts a patient's blood oxygen and pulse, serving as a reminder to check blood oxygen levels
NOW THAT U KNOW WHAT THIS IS , LET ME TELL YOU WHY IM DOING THIS. I GAVE BIRTH TO A PRECOUS LITTLE GIRL, PEYTON BRYCE CRYMES ON NOV. 17,2008 AT ST FRANCIS HOSPITAL IN MONROE LOUISIANA. LITTLE DID WE KNOW SHE WAS A SICK GIRL, HERE'S HER STORY!
Peyton Bryce Crymes, daughter of Lindsay Danielle Crymes, was born on Nov. 17 2008 @ 7:40pm, she weighted 6.2 pounds & was 17 inches long~ right after birth the drs found out she had heart problems. She was immedialty rushed to Arkansas Children Hospital for better treatment. She does not have a plumnary artery witch carries the blood to the lungs and to the rest of the body, & she also has a hole in the bottom chamber. She had her 1st surgery on Nov. 26th 2008. She did great!
She had her 2nd surgery on april 3rd 2009.
PEYPEY JUS HAD HER 3RD OPEN HEART SURGERY ON APRIL 29TH 2010 AND SHE DID GREAT 9 AND HALF HOURS LONG SHE IS SO PINK NOW.
COMPLETE DIAGNOSIS- TOF PA VSD ASD 22Q VON WILLEBRAND AND COLOR BLIND!
WE GO IN JUNE 2012 FOR HEART SURGERY 4
BY THE TIME AN INFANT IS ONE HOUR OLD, THEY HAVE BEEN PICKED IN THE HEEL, GAVE BLOOD AND POKED SOME MORE! WHY CANT THIS BE PASSED TO SEE IF THEY HAVE A HEART CONDITION!
CHD KILLS MORE LIVES THAN ANY CHILDHOOD CANCER COMBINED!
NOW AS A MOMMY AND A LIFE LONG RESIDENT OF LOUISIANA, CAN YALL STAND UP BEHIND ME AND GET THIS PASSED!!!!!!
