SpO2 ANALYSISSpO2 ANALYSIS
Oxygen ‐ hemoglobin Affinity Changes.
The functions of hemoglobin are oxygen pickup and delivery. The hemoglobin has an affinity (the strength of bond between oxygen and hemoglobin) that can be increased or decreased due to various situations. If hemoglobin has an increased affinity it is highly saturated; but oxygen is less available for release to the tissuesaffinity, it is highly saturated; but oxygen is less available for release to the tissues due to the strong bond. The reverse is also true.

E.S TECK COMPLEX INTENDED USES
• HRV module: To analyze the basic rhythms of the NN or RR intervals in electrocardiograms, both in the time domain and in the frequency domain (short time 5 minutes)
• It only provides numerical analyses of the input electrocardiogram. • Estimate of the parasympathetic and sympathetic system
stimulation. • PP module: Analyze the pulse waveform by photoelectric
plethysmography and Pulse rate. • Evaluation of Large and small artery
• EIS module: • Monitoring of diseases, functional and lifestyle ‘ treatments
• Adjunct to conventional diagnosis of ADHD children• BIA module :• Calculation and Historical Tracking of body composition

Resistance and Reactance measurements
• Resistance is a measure of how difficult it isResistance is a measure of how difficult it is for electricity to flow through an object.
• Reactance• Reactance
Most objects have some capacitance, which is a f bili l i lmeasure of ability to store an electrical
charge. The more capacitance the object has, h f h h di ior the faster the current changes direction,
the less the object will “react” to the current.

Clinical application in survival in colorectal cancercolorectal cancer
The survival curves for the 2 categories of phase angle are shown. Patients with a phase angle < 5.57
had a median survival of 8.6 mo (95% CI: 4.8, 12.4; n = 26), and those witha phase angle > 5.57 had a mediana phase angle > 5.57 had a median survival of 40.4 mo (95%CI: 21.9, 58.8; n = 26); this difference was
significant (P = 0.0001).
