Assessment of blood gas status is important in the management of patients with chronic pulmonary disease. Arterial puncture is often painful and may damage the arterial wall. Measurement of oxygen saturation by transcutaneous oximetry offers a non-invasive alternative to arterial methods but does not allow assessment of partial pressure of carbon dioxide. We have examined the value of oximetry ...

BACKGROUND patients with hypoxemia (blood oxygen saturation <90%) are usually hospitalized, although validated criteria (eg, the Pneumonia Severity Index [PSI]) suggest outpatient treatment is safe. We sought evidence to support or refute the practice. METHODS all patients in Edmonton, Alberta, Canada with pneumonia assessed at any of 7 emergency departments (EDs) and then discharged were enr...

introduction inhalation sedation is used for pain and anxiety control in dentistry. hypoxia is the most important side effect which can be detected using pulse oximetry, however, there are different opinions about the use of this instrument. this study has been designed to investigate this subject. methods and materials in this study, 32 adult patients from periodontal surgical department were ...

BACKGROUND Perioperative disturbances of microvascular blood flow and oxygenation in the intestinal tract have been hypothesized to play an important role in development of the multiple organ dysfunction syndrome. Herein, increased intra-abdominal pressure (IAP) has been identified as a key factor in the initiation of the pathophysiologic cascade. The authors hypothesized that increasing the IA...

In this paper, the rough set theory is used to deal with the relations between patient's temperature, oxygen saturation, blood pressure and decision ADM-DECS in care of postoperative patients, we select 28 postoperative patients as a sample, take ADM-DECS as a decision attribute and take patient's temperature, oxygen saturation, blood pressure as

INTRODUCTION Pulse oximetry is a useful tool for clinical and investigational purposes for indirect measurements of oxygen saturation [1-3]. Measurement of oxygen saturation with pulse oximetry (SpO2) can be used for evaluation and control of hypoxemia in chronic obstructive pulmonary disease (COPD). As pulse oximetry is a non–invasive device, it can be used instead of arterial blood gases (ABG...

mean values for Po2 of 58, 60, and 72 mm Hg, respectively, were found for the three groups. When the same patients breathed oxygen via a nasal cannula or face mask at flow rates of 8 to 12 L/min, values were 106, 128, and 160 mm Hg, respectively. In all instances hemoglobin saturation values in excess of 95% were obtained when the patient breathed oxygen. In 15 patients measurements of the oxyg...

conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...

BACKGROUND Determination of the blood oxyhemoglobin saturation in the retinal vessels of the eye can be achieved through spectrophotometric retinal oximetry which provides access to the state of oxyhemoglobin saturation in the central nervous system circulation. The purpose of this study was to test the capability of the Oxymap T1 oximeter to detect systemic hypoxemia and the effect of suppleme...

BACKGROUND Stressors in the intensive care unit (ICU) impair patients' comfort, excite the stress response, and increase oxygen consumption in their body. Non-medical interventions are recommended by several studies as a treatment to improve comfort in the ICU patients. Sensory stimulation is one of the most important interventions. Since arterial blood oxygen saturation is an important index o...
