Best Overall: Contec CMS50DL When researchers at the University of California at San Francisco tested six low-cost finger pulse oximeters , the Contec CMS50DL was one of two that read oxygen saturation precisely enough to meet the International Organization for Standardization (ISO) criteria for accuracy .
The normal oxygen saturation level is 97–100% (OER #1). Older adults typically have lower oxygen saturation levels than younger adults. For example, someone older than 70 years of age may have an oxygen saturation level of about 95%, which is an acceptable level .
Per Medicare guidelines, oximeters (E0445) and replacement probes (A4606) will be considered non- covered because they are monitoring devices that provide information to physicians to assist in managing the member’s treatment.
CONCLUSIONS: Many low-cost pulse oximeters sold to consumers demonstrate highly inaccurate readings. Nonetheless, further development of accurate , low-cost oximeters for use in clinical practice is feasible and, if pursued, could improve access to safe care, especially in low-income countries.
A pulse oximeter measures two things: Blood Oxygen Saturation (SpO2): The measurement that indicates what percentage of blood is saturated. Pulse Rate : Pulse rate is nothing but the heart rate that indicates the number of times a heart beats per minute.
Pulse oximetry is also used to check the health of a person with any condition that affects blood oxygen levels, such as: Heart attack .
Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent . Values under 90 percent are considered low.
Low blood oxygen levels can result in abnormal circulation and cause the following symptoms: shortness of breath . headache. restlessness. dizziness. rapid breathing . chest pain. confusion . high blood pressure.
Your body needs oxygen to work properly, so if your oxygen levels are too low , your body may not work the way it is supposed to. In addition to difficulty breathing, you can experience confusion, dizziness, chest pain, headache, rapid breathing and a racing heart.
While people with COPD often have lower oxygen saturation and can safely fall between 92% and 88% when it comes to a normal oxygen saturation for them, it is still essential not to let it fall too low . An oxygen level below 88% can be dangerous for any period of time.
Conditions for Which Oxygen Therapy May Be Covered Examples of these symptoms and findings are pulmonary hypertension , recurring congestive heart failure due to chronic cor pulmonale, erythrocytosis, impairment of the cognitive process, nocturnal restlessness, and morning headache.
Supplemental home oxygen therapy is considered medically necessary during sleep in an individual with any of the following conditions: Unexplained pulmonary hypertension , cor pulmonale, edema secondary to right heart failure , or erythrocytosis and hematocrit is greater than 56%; or.
Causes of incorrect readings on pulse oximetry Hypoperfusion. Vasoconstriction . Calloused skin. Excessive movement. Incorrect sensor application. Methemoglobinemia .
The oxygen level from a pulse oximeter is reasonably accurate . Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas.
As stated above, a reading of 94 to 99 percent or higher indicates normal oxygen saturation , and anything below 90 percent is considered to be low blood oxygen , also known as hypoxemia.
