Pulmonary (or pulmonic [4]) regurgitation (or insufficiency, incompetence) is a condition in which the pulmonary valve is incompetent [5] and allows backflow from the pulmonary artery to the right ventricle of the heart during diastole. [6] While a small amount of backflow may occur ordinarily, it is usually only shown on an echocardiogram and ...
distension of pulmonary vascular bed causes tachypnoea: Chvostek sign: František Chvostek: endocrinology: hypocalcemia: tapping over facial nerve elicits abnormal muscle contraction(s) Claybrook sign: Edwin Claybrook: emergency medicine, surgery: blunt abdominal trauma: heart and/or breath sounds heard through abdominal wall indicate rupture ...
pulmonary regurgitation A Graham Steell murmur is a heart murmur typically associated with pulmonary regurgitation . [ 1 ] [ 2 ] It is a high pitched early diastolic murmur heard best at the left sternal edge in the second intercostal space with the patient in full inspiration , originally described in 1888.
Integrated pulmonary index (IPI) is a patient pulmonary index which uses information from capnography and pulse oximetry to provide a single value that describes the patient's respiratory status. IPI is used by clinicians to quickly assess the patient's respiratory status to determine the need for additional clinical assessment or intervention.
The pneumonia severity index (PSI) or PORT Score is a clinical prediction rule that medical practitioners can use to calculate the probability of morbidity and mortality among patients with community acquired pneumonia. [1] The PSI/PORT score is often used to predict the need for hospitalization in people with pneumonia. [2]
In 1994, a new definition was recommended by the American-European Consensus Conference Committee [6] [10] which recognized the variability in severity of pulmonary injury. [51] The definition required the following criteria to be met: acute onset, persistent dyspnea; bilateral infiltrates on chest radiograph consistent with pulmonary edema
The presence of this murmur is a good positive predictor for AR and the absence of this murmur strongly suggests the absence of AR. An Austin Flint murmur is usually associated with significant aortic regurgitation. Early diastolic Pulmonary regurgitation: Pulmonary regurgitation is most commonly due to pulmonary hypertension (Graham-Steell ...
A bronchodilator is also given in certain circumstances and a pre/post graph comparison is done to assess the effectiveness of the bronchodilator. See the example printout. Functional residual capacity (FRC) cannot be measured via spirometry, but it can be measured with a plethysmograph or dilution tests (for example, helium dilution test).
