We studied 16 male patients with COPD. Using a bicycle ergometer, each patient started to exercise with a work load of 25W, which was increased in steps of 5W in one minute intervals until the symptom-limited endpoint. The same trial with oxygen inhalation was also performed in 6 out of 16 patients. During the exercise testing in room air (n=16), [K^+]_a increased from the baseline (3.82 ± 0.18 mEq / L) to 4.62±0.33 mEq/L (p\u003c0.01). Once exercise stopped, [K^+]_a decreased rapidly. In all patients, the increase in minute ventilation volume(V^^・_E) was significantly correlated with the elavation of [K^+]_a (p\u003c0.05). Ventilatory response to [K^+]_a (the slope of △V_E/△K^+) varied markedly among the patients (13.1 to 50.7 L/min/mEq/L), and was correlated with forced vital capacity (FVC) (P\u003c 0.05). During the trial with oxygen inhalation (n=6), the mean slope of △V^^・_E/△K^+ was not depressed, compared with the room air run, which was 21.9±11.9 in the former and 25.4±13.1 L/min/mEq/L in the latter, respectively. These findings indicate that: 1) ventilation and [K^+]_ a were correlated during exercise; 2) the slope of ventilatory response to [K^+]_a differed markedly among the patients, and was correlated with FVC; and 3) hyperoxia did not significantly affect the ventilation[K^+]_a relationship. We conclude that, while [K^+]_a may play some role, certain unknown factors may also be involved in determining the degree of exercise hyperpnea in patients with COPD.", "subitem_description_type": "Abstract"}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Niigata University School of Medicine"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AA00508361", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "05677734", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Nakajima, Toshiaki"}], "nameIdentifiers": [{"nameIdentifier": "52580", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohdaira, Tetsuro"}], "nameIdentifiers": [{"nameIdentifier": "52581", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Satoh, Makoto"}], "nameIdentifiers": [{"nameIdentifier": "52582", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kurashige, Kazuyuki"}], "nameIdentifiers": [{"nameIdentifier": "52583", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yokota, Tatsuya"}], "nameIdentifiers": [{"nameIdentifier": "52584", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Suzuki, Eiichi"}], "nameIdentifiers": [{"nameIdentifier": "52585", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kioi, Satoru"}], "nameIdentifiers": [{"nameIdentifier": "52586", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Arakawa, Masaaki"}], "nameIdentifiers": [{"nameIdentifier": "52587", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-06"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "46(3)_81-87.pdf", "filesize": [{"value": "675.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 675100.0, "url": {"label": "46(3)_81-87.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/6369/files/46(3)_81-87.pdf"}, "version_id": "08fb1191-6e1b-4ede-a95f-cb65f7842e0d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "arterial plasma potassium", "subitem_subject_scheme": "Other"}, {"subitem_subject": "exercise hyperpnea", "subitem_subject_scheme": "Other"}, {"subitem_subject": "hyperoxia", "subitem_subject_scheme": "Other"}, {"subitem_subject": "chronic obstructive pulmonary disease", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "The Relationship between Arterial Plasma Potassium Concentration and Ventilation during Exercise in Patients with Chronic Obstructive Pulmonary Disease", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "The Relationship between Arterial Plasma Potassium Concentration and Ventilation during Exercise in Patients with Chronic Obstructive Pulmonary Disease"}, {"subitem_title": "The Relationship between Arterial Plasma Potassium Concentration and Ventilation during Exercise in Patients with Chronic Obstructive Pulmonary Disease", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "610"], "permalink_uri": "http://hdl.handle.net/10191/33084", "pubdate": {"attribute_name": "公開日", "attribute_value": "2015-08-21"}, "publish_date": "2015-08-21", "publish_status": "0", "recid": "6369", "relation": {}, "relation_version_is_last": true, "title": ["The Relationship between Arterial Plasma Potassium Concentration and Ventilation during Exercise in Patients with Chronic Obstructive Pulmonary Disease"], "weko_shared_id": null}
