Pulsus paradoxus in the bedside assessment of patients with bronchial asthma.
Pulsus paradoxus (PP) was measured in 35 patients with bronchial asthma. The presence and degree of PP correlated well with the clinical conditions of the patient and with peak expiratory flow rate (PEF). PP and PEF are useful bedside measurements in the assessment and management of patients with bronchial asthma. Although the degree of PP is usually directly related to the severity of the attack of asthma, it was absent in the one patient who remained severly ill with unreleived bronchospam when he became exhausted. Our experience with this patient, and with previous patients who are not included in the present analysis, emphasises the fact that PP must not be considered in isolation but in conjunction with the patient's clinical state and with other indices of the severity of the astmatic attack.
