Hyposaturation

Hyposaturation typically refers to a state of low oxygen saturation in the blood (hypoxemia), where oxygen levels drop below 90% (T90). It is a critical, measurable parameter in medical contexts, often associated with respiratory disorders, postoperative recovery, and cognitive impairment. It can also refer to low saturation in other contexts, such as nutritional deficiencies or, in a technical context, low voltage differences in electronic components. 

Key Medical Aspects of Hyposaturation:

• Definition: Often defined as oxygen saturation <90% <90% (T90) in medical monitoring.

• Causes: Common causes include pneumonia, asthma, COPD, and general respiratory, cardiovascular, or neurological issues.

• Clinical Impact: Associated with postoperative cognitive decline following surgeries like total hip arthroplasty and is a key indicator of hypoxemia in critically ill patients.

• Monitoring: Measured via pulse oximetry or arterial blood gas analysis. 

Contextual Usage:

• Medical/Pathological: Describes deficiencies in oxygenation or, historically, in nutritional contexts (e.g., Vitamin C deficiency).

• Technical/Electronics: Refers to a specific feature in Sanken Electric's SI-3000KM Series power management components, indicating a design with a low difference between input and output voltages (Vdif=0.6 Vmax). 

Symptoms of Hypoxemia (Low Oxygen):

• Shortness of breath

• Rapid breathing

• Wheezing

• Coughing

• Confusion or rapid heart rate
