Objective:
This study examined the resting oxygen consumption in patients with a twin pregnancy and compared the results with those of singleton pregnancies.
Methods:
In 15 patients with a twin and 26 patients with a singleton pregnancy, the resting oxygen consumption was measured using an open-circuit ventilatory system during the third trimester of pregnancy.
Results:
The average resting oxygen consumption in patients with a twin pregnancy was 231+/-25 ml/min, significantly higher than that in patients with a singleton pregnancy (209+/-24 ml/min, P<0.05).
Conclusion:
Our results indicate an estimated increase in metabolic rate in patients during the third trimester of a twin pregnancy compared with those with a singleton pregnancy.

Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves the...
