Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults: Conclusion
In an attempt to determine the factors that would be most predictive of arterial oxygen desaturation, we examined factors related to minimum Sa02. Three factors were found to be independent predictors: (1) low baseline Sa02; (2) the duration of the procedure; and (3) indices of left ventricular failure such as increased pulmonary arterial diastolic pressure, […]
Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults: Discussion
Arterial hypoxemia may be associated with arrhythmias, myocardial ischemia, myocardial infarction, or congestive heart failure in the patient with coronary artery or valvular heart disease. It is difficult to predict, in any particular patient, the oxygen tension necessary to prevent morbidity; however, an arterial oxygen tension (Pa02) less than 60 mm Hg is considered by […]
Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults: Angiography
When the effect of coronary cineangiography, left ventriculography, and balloon inflation during percutaneous transluminal coronary artery angioplasty on Sa02 were measured, two patients were excluded, one because he was having multiple episodes of desaturation with such frequency that we were unable to establish accurate readings for Sa02 before angiography or baseline values before angioplasty, and […]
Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults: Results
The patient population had a mean age of 53 ±3 years (range, 21 to 83 years) and mean weight of 83 ± 3 kg. Nineteen patients were men, and ten were women. Eighteen patients (62 percent) had a history of smoking. Nineteen patients received sedation before or during catheterization (14 with diazepam [2 to 15 […]
Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults: Materials and Methods
From the continuous recording of SaOa, the following data were derived for each patient: (1) lowest Sa02 persisting for at least eight seconds during the entire procedure; (2) number and duration of episodes during which Sa02 decreased below 90 percent; (3) the Sa02 immediately before and the lowest Sa02 in the one minute following ventriculography, […]
Continuous Oxygen Saturation Monitoring during Cardiac Catheterization in Adults
Cardiac catheterization has been associated with a variety of complications, including arrhythmias, myocardial infarction, hypotension, and acute pulmonary edema. Hypoxemia may occur during cardiac catheterization and could contribute to morbidity, as well as potentially alter physiologic parameters measured at catheterization. We know of only two published studies in which arterial hemoglobin oxygen saturation (SaOJ was […]

Resource Utilization of Adults Admitted to a Large Urban Hospital With Community-Acquired Pneumonia Caused by Streptococcus pneumoniae: Summary
Excluding those patients who died, median length of stay was 2 days longer in patients who met our definition of delayed discharge. If patients were discharged within 1 day of meeting our clinical definition and receiving oral antibiotic therapy, the median length of stay for these 88 patients would have been 3 days (range, 2 […]
