FIELD: medicine. ^ SUBSTANCE: what is conducted is 10-minute hypoxic loading test (LT) using oxygen poor (up to 10-11%) normobaric gas mixture with reoxygenation time recorded and physiological parameters controlled. It is followed by calculating a functional deviation coefficient (Cf) in standard units by formula: Cf=öRR/10+öHR/10+öSBP/10+öDBP/10+öSaO2/10+Tr/60, wherein öRR/10 is a gradient of respiratory rate (respiratory rate increment for a hypoxic time divided by 10), standard units; öHR/10 is a gradient of heart rate (heart rate increment for a hypoxic time divided by 10), standard units; öSBP/10 is a gradient of systolic blood pressure (increase/decrease of systolic blood pressure (mm Hg) for a hypoxic time divided by 10), standard units; öDBD/10 is a gradient of diastolic blood pressure (increase/decrease of diastolic blood pressure (mm Hg) for a hypoxic time divided by 10), standard units; öSaO2/60 is a gradient of SaO2 (decrease of arterial oxygen saturation (%) for a hypoxic time divided by 10), standard units; Tr/60 is a gradient of reoxygenation (a reoxygenation time (sec.) divided by 60), standard units. If Cfëñ6.5, an optimum level of functional reserves is stated; the value 6.5<Cfëñ12 means decrease of functional reserves; while depleted functional reserves are shown by the value Cf>12. ^ EFFECT: use of the method enables the objective assessment of manifestation of the deviations, including the pre-clinical one for the purpose of directed correction. ^ 3 ex |
