High flow humidification oxygen therapy for elderly patients with abnormal respiratory rhythms and difficult weaning:report of two cases and literature review / 中华老年医学杂志

ABSTRACT

Objective To evaluation the effect of high flow humidification oxygen (HFHO) therapy for two elderly cases with respiratory rhythm abnormalities and multiple organ dysfunction weaning from mechanical ventilation.Methods Clinical features and weaning processes of two elderly cases with respiratory rhythm abnormalities and multiple organ dysfunction were analyzed and the related literature was reviewed.Results Two elderly patients had multiple organ dysfunction,respiratory rhythm abnormalities and other difficult weaning factors.After a variety of unsuccessfully weaning patterns,HFHO was successfully used in helping patients wean from mechanical ventilation,with gradually increasing the time of HFHO and restoring respiratory muscle function.Conclusions For elderly patients with artificial airways,respiratory muscle dysfunction(long-term mechanical ventilation)and/or respiratory rhythm abnormalities,HFHO is a promising weaning method.
