In the 1930s, Hess, followed by Chapple, described the use of oxygen in infants 10). Specifically, Chapple's unit delivered 100% oxygen at 4 L/min, resulting in a fraction of inspired oxygen (FiO 2) of approximately 46% in the incubator. Today, a FiO 2 of 46% is considered a high concentration of oxygen for premature infants. Your “Normal” SpO 2 Range. According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, increased heart rate The oxygen saturation level (also known as SPO2) stands for serum (S) pressure (P) and oxygen (O2). In most people, the body needs a minimum of 95% of oxygen in the blood to function ably.
To avoid carbon dioxide (CO 2) narcosis, O 2 must be provided in a controlled fashion with a target saturation of only 88–92% [ 3 ]. This recommendation was studied in a prehospital care setting of 405 patients with COPD exacerbations: When O 2 was delivered via nasal prongs with a target percentage of oxygen saturation of arterial blood of
The independent variable of interest was oxygen saturation; the outcome was the composite endpoint of 30-day mortality or hospitalization. Results: the study evaluated 2923 individuals with pneumonia who were treated as outpatients at any of 7 EDs. The patients' mean age (standard deviation [SD])was 52 (20) years; 47% were women; 74% were low

Respiratory rate is your pace of breathing, and it tends to slow while sleeping. A low respiratory rate can be caused by sleep apnea, heartburn, or other health conditions. A high respiratory rate can be caused by anxiety, infection, or lung conditions. See a doctor if you or a partner notices that you have a low or high respiratory rate while

Normal amounts — called oxygen saturation rates — range between 95% and 100% blood-oxygen, whereas a rate of 93% signals physicians that a patient may soon suffer organ damage due to a lack of
