The values of SpO2 above 89% are not considered in the calculation of HTi, as such saturation levels do not contribute to the treatment. SpO2 values below 75% count as 75%. HTi is calculated as an integral value of SpO2 readings made with 1 s sampling frequency and divided by 60 in order to produce a “per minute” value.
A related condition, orthodeoxia, describes the clinical finding of low oxygen saturation in the upright position, which improves when lying down. [3] Platypnea and orthodeoxia (low oxygen levels when in upright posture) can co-exist, and this combination is named platypnea-orthodeoxia syndrome. [4] [5] The syndrome is considered extremely rare ...
The body maintains a stable level of oxygen saturation for the most part by chemical processes of aerobic metabolism associated with breathing.Using the respiratory system, red blood cells, specifically the hemoglobin, gather oxygen in the lungs and distribute it to the rest of the body.

The drop in blood pressure may be sudden (vasovagal orthostatic hypotension), within 3 minutes (classic orthostatic hypotension) or gradual (delayed orthostatic hypotension). [4] It is defined as a fall in systolic blood pressure of at least 20 mmHg or diastolic blood pressure of at least 10 mmHg after 3 minutes of standing.

When a person is recumbent, or is lying down, blood is redistributed from the lower extremities and abdominal cavity (splanchnic circulation) to the lungs. [5] Failure to accommodate this redistribution results in decreased vital capacity and pulmonary compliance , further causing the shortness of breath experienced in PND.
