METHOD FOR DIAGNOSING THE CASES OF ACUTE LUNG DISORDER Russian patent published in 2004 - IPC

FIELD: medicine.

SUBSTANCE: method involves measuring patient height and determining reference body weight of the patient (m_ref). Excessive body weight (m_exc) is determined. Age (a) is taken into consideration. Reference thoracic lung compliance (C_ref) is calculated from formulas C_ref = (m_ref) - (m_exc)/3 - (a-3)/3 in patients elder than 30 years and having excessive body weight, C_ref = (m_ref) - (a-3)/3 in patients elder than 30 years and having no body weight excess, C_ref = (m_ref) - (m_exc)/3 in 30 years old patients having excessive body weight, C_ref = (m_ref) in 30 years old patients having no body weight excess, where C_ref is the reference thoracic lung compliance in ml/cm of water column, m_ref is the reference body weight of the patient in kg, m_exc is the excessive body weight of the patient in kg, a patient age in years. Thoracic lung compliance (C) is measured and ratio of C/ C_ref is calculated. The value being from 1.4 to 1.99, the first degree of acute lung disorder is to be diagnosed. The value being from 2 to 2.99, the second degree of acute lung disorder is to be diagnosed. The value being from 3 to 5, the third degree of acute lung disorder is to be diagnosed. The value being greater than 5, the fourth degree of acute lung disorder is to be diagnosed.

EFFECT: high accuracy of diagnosis.
