  • Look Inside

A disposable condenser humidifier (DH) was developed for the purpose of keeping heat and moisture of inhalated gas, thereby preventing postoperative respiratory complications due to inhalation of dried anesthetic gas. The experi-mental and clinical study showed that the preser-vation of respiratory function was attained by using DH in terms of physiological shunt in the lung and alveolar-arterial PO2 difference. In addition, the patients treated with DH could cough up serous sputum easily immediately after operation. Electromicroscopic study in the dog experiments indicated better preservation of the mucociliary epithelium of the bronchus in the group with DH. It was concluded that DH was effective for preserving respiratory function during and after operation.
