Pulse oximeter is a device used for non-invasive measurement of arterial oxygen saturation and pulse rate. And oximeters are widely used in hospitals, clinics, operating rooms and homes. Both oxygen saturation and pulse rate are vital signs of the patient. The oximeter is inexpensive and can report accurate readings within a few seconds. Speed is very important, especially in emergency situations.
For many patients, doctors usually recommend exercise to improve their physical strength and overall health. However, exercise can cause shortness of breath. Patients should use a pulse oximeter to monitor their oxygen saturation during exercise so that they can adjust their pace as the oxygen saturation decreases.
Patients with severe heart disease usually experience low SpO2 levels. A pulse oximeter will help them monitor their condition and use supplemental oxygen when needed. The heart rate chart produced by the pulse oximeter shows that changes in blood volume during the heart beat can usually indicate certain heart conditions well.Pilots, climbers and people at high altitudes also use pulse oximeters to prevent hypoxia.Pulse oximeter can also help athletes in altitude training. The decrease in oxygen levels will increase the athlete's red blood cells and help increase their endurance.
Many patients with low oxygen saturation can increase their saturation all the way to 93% through good breathing techniques. Practice and pulse oximeter will help patients reach this level of efficiency.
What are the benefits of a pulse oximeter?
- Monitor oxygen saturation over time
- Be alert to dangerously low oxygen levels, especially newborns
- Reassure people with chronic respiratory or cardiovascular diseases
- Assess the need for supplemental oxygen
- Monitor the blood oxygen saturation of a person under anesthesia
- Indicate the dangerous side effects of taking medications that affect breathing or blood oxygen saturation.
- Determine the effectiveness of respiratory interventions, such as oxygen therapy and ventilators
- The doctor evaluates the safety of the patient during physical exercise or exercise (for example, people with cardiovascular or respiratory diseases)
What is the function of a pulse oximeter?
- Lung diseases such as chronic obstructive pulmonary disease (COPD), asthma, pneumonia and lung cancer
- Heart disease, such as heart attack or heart failure and congenital heart disease
- Assess the efficacy of new lung drugs
- Assess how the ventilator works for patients who rely on the ventilator
- Monitor oxygen levels during or after surgical procedures that require sedation
- Determine the effectiveness of supplemental oxygen therapy, especially when in new therapy
- Assess the individual's ability to withstand increased exercise.
- Assess whether it will appear the individual’s temporary cessation during sleep (if in the case of sleep apnea during a sleep study)
How accurate is the pulse oximetry reading?
Pulse oximetry is usually an accurate test. Either way, it will always provide results with a 2% difference. For example, if the reading is 82%, the actual oxygen saturation level may be between 80% and 84%. However, the waveform quality and personal evaluation must be considered. Factors will affect accuracy, such as exercise, temperature or nail polish. Generally, more than 89% of blood should carry oxygen. This is the level of oxygen saturation required to maintain cell health. For most healthy individuals, an oxygen saturation level of 95% is considered normal. A level of 89% indicates potential hypoxemia or insufficient oxygen reaching the body’s tissues.
