Arterial oxygen tension in relation to age in hospital subjects.
One hundred and seventy-seven hospital patients whose ages ranged from 20 to 80 years were studied to determine whether or not there are any changes in arterial oxygen tension (during the breathing of room air) in relation to age. The findings indicated that there is an inverse correlation between age and arterial oxygen tension. This may be of great clinical significance since anoxemia has a p...
متن کاملThe normal alveolar-arterial oxygen-tension gradient in man.
2. The gradient increased with age and with inspired O2 concentration up to 60%. Above 60%, during normal breathing, there was no significant change in gradient. 3. Breathing 100% 0, in deep breaths decreased the gradient in all age-groups, significantly so in subjects of 50 years and younger. The remaining gradient was due to anatomical venous shunt. 4. When this anatomical shunt was allowed f...
متن کاملArterial oxygen tension during apnoea in parturient women.
The decrease in arterial oxygen tension, during 60 sec of apnoea with exposure to room air, was studied in twelve healthy parturient women undergoing Caesarean section under endotracheal fluroxene-oxygen anaesthesia. Eight young gynaecological patients, anaesthetized in an identical manner, served as controls. The reduction in oxygen tension was significantly greater in the pregnant women than ...
متن کاملBlood eosinophil counts and arterial oxygen tension in acute asthma.
OBJECTIVE To investigate whether during acute asthma episodes a decrease in blood eosinophil count could correlate with the severity of the disease. DESIGN Prospective study on paediatric asthmatic patients admitted for acute asthma exacerbation between January 1992 and August 1993. All patients were regularly followed up in an outpatient clinic and had had a complete clinical evaluation < 1 ...
متن کاملIntravenous oxygen administration in a rat model of hypoxia.
Introduction Hypoxemia reduces tissue oxygen delivery, thus compromising cell metabolism and organ function. Supplemental oxygen at high concentrations may prove ineffective and issues relating to hyperoxia, barotrauma, mechanical ventilation and extracorporeal oxygenation are well documented [1,2]. A century ago, Tunnicliffe et al reported rapid and safe relief of cyanosis in patients by admin...
