Estimation of airway obstruction using oximeter plethysmograph waveform data

Respiratory Research, 2005
Background Validated measures to assess the severity of airway obstruction in patients with obstructive airway disease are limited. Changes in the pulse oximeter plethysmograph waveform represent fluctuations in arterial flow.

Relationship between pre-anesthetic and intra-anesthetic airway resistance in patients undergoing general anesthesia: A prospective observational study. [PDF]

PLoS ONE, 2017
Surgery patients in Japan undergo routine spirometry testing prior to general anesthesia. The use of a flow sensor during general anesthesia has recently become common. However, it is not certain whether the information derived from flow-volume curves is

Acute airway obstruction management in scorpion envenomation to submandibular region: A case report

Otolaryngology Case Reports, 2018
Acute airway obstruction following scorpion envenomation to the head and neck region can present a unique challenge to a clinical practitioner and will require expeditious management to appropriately secure the airway. We present the case of acute airway

Fractional exhaled nitric oxide could identify early spirometry change in clinically suspected asthma patients without airway obstruction

European Journal of Inflammation, 2021
Fractional exhaled nitric oxide (FeNO) has been proposed as a non-invasive biomarker for allergic inflammation seen in asthma. The aim of this study was to assess the ability of FeNO to discriminate spirometry and lung volume measurements between those ...

Management of airway obstruction [PDF]

BJA Education, 2018
Key points • Patients with airway obstruction are high risk; they should be managed by senior anaesthetic and surgical staffs that have good technical and non-technical skills. • There is no universal ‘best approach’ with experts often providing differing opinions on optimal management.

Ultrasonographic Detection of Airway Obstruction in a Model of Obstructive Sleep Apnea

Ultrasound International Open, 2017
Purpose Obstructive sleep apnea (OSA) is a common clinical disorder characterized by repetitive airway obstruction during sleep. The gold standard for diagnosis of OSA, polysomnogram (PSG), cannot anatomically localize obstruction. Precise identification

Negative pressure pulmonary edema: a case report

BMC Anesthesiology, 2019
Background The negative pressure pulmonary edema is rare clinical situation which caused mainly by upper airway obstruction. However except upper airway obstruction, there may be other pathophysiological disorders making patients more vulnerable to ...

Smoking Status Modifies the Relationship between Th2 Biomarkers and Small Airway Obstruction in Asthma

Canadian Respiratory Journal, 2021
Background. Cigarette smoking and Th2-inflammation are both crucial in the pathogenesis of asthma. However, it is unknown whether smoking can affect the association between Th2-inflammation and small airway obstruction in adults with asthma.

Importance of slow vital capacity in the detection of airway obstruction

Jornal Brasileiro de Pneumologia, 2013
OBJECTIVE: To investigate the presence of airway obstruction by determining the FEV1/FVC and FEV1/slow vital capacity (SVC) ratios. METHODS: This was a quantitative, retrospective cross-sectional study.
