Arterial desaturation in HIV positive patients undergoing sputum induction.
Arterial oxygen saturation (SaO2) was monitored continuously during and immediately after sputum induction in 41 HIV positive patients with respiratory symptoms and in 20 symptomless medical and nursing staff, who acted as control subjects. Arterial oxygen desaturation (defined as SaO2 less than or equal to 92%) occurred during sputum induction and persisted for up to 20 minutes after the end o...
متن کاملEffect of sputum induction on arterial oxygen saturation and spirometry in HIV-infected patients.
We wanted to study the effect of sputum induction on forced expiratory volume in one second (FEV1) and on oxygen saturation in normal controls, asymptomatic human immunodeficiency virus (HIV)-seropositive individuals, and HIV-seropositive patients under investigation for suspected Pneumocystis carinii pneumonia (PCP). Over a five month period, sputum induction with ultrasonically nebulized 3% s...
متن کاملSafety of sputum induction.
We have read with great interest the article by Castagnaro et al (October 1999),1 reporting a significant drop in oxygen saturation in the absence of an equivalent drop in FEV1 during sputum induction. This, however, has not been our experience. Although we agree that FEV1 may fall in asthmatics, COPD patients,2 and normal volunteers,3 we have not seen significant changes in oxygen saturation. ...
متن کاملEffect of sputum induction on spirometric measurements and arterial oxygen saturation in asthmatic patients, smokers, and healthy subjects.
BACKGROUND Sputum production induced by inhalation of hypertonic saline solution has been proposed as a technique to collect secretions and inflammatory cells from the airways of subjects with bronchial asthma or with a history of smoking. The aim of this study was to determine the effect of a sputum induction procedure on spirometric results and arterial oxygen saturation (SaO(2)) in asthmatic...

Introduction: Artificial airway stimulates the sympathetic system and the loss of ciliated cells and the accumulation of secretions. Therefore, since these patients do not have the ability to discharge, periodic suction is needed. This study aimed at comparing the effect of open suction endotracheal tube using 2 different sized suction catheters on arterial blood oxygen saturation in critical c...
