Spirometry Reference Equations Including Existing and Novel Parameters (Douglas Johnson) All Scholarly Works (2023)

Introduction: Spirometry is an essential component of pulmonary function testing, with interpretation dependent upon comparing results to normal. Reference equations for mean and lower limit of normal (LLN) are available for usual parameters, including forced ...

PAP therapy and readmission rates after in-hospital laboratory titration polysomnography in patients with hypoventilation (Karin Johnson, Vida Rastegar, Nicholas Scuderi, et al.) All Scholarly Works (2022)

Study objectives: Hypoventilation associated with sleep disordered breathing in inpatients is associated with higher risk of morbidity, hospitalizations and death. In-hospital titration polysomnography qualifies patients for positive airway pressure (PAP) therapy and optimizes settings, but ...

Respiratory Candida in Patients with Bronchitis, Mucus Plugging, and Atelectasis (Douglas Johnson, Suresh Chirumamilla and Armando Paez) All Scholarly Works (2020)

Background: The significance of Candida in pulmonary secretions is unclear, and usually is regarded as colonization, not contributing to symptoms or disease. Yet, in our experience, Candida seemed associated with chronic sputum, mucus plugging, atelectasis, ...

Cardiovascular and Somatic Comorbidities and Sleep Measures Using Three Hypopnea Criteria in Mild Obstructive Sleep-Disordered Breathing: Sex, Age and Body Mass Index Differences in a Retrospective Sleep Clinic Cohort (Karin Johnson, Douglas Johnson, Vida Rastegar, et al.) All Scholarly Works (2020)

Study objectives: To describe sex, age and body mass index (BMI) differences in comorbidities and polysomnography (PSG) measures, categorized using three different apnea-hypopnea index (AHI) criterion, in sleep clinic patients with mild obstructive sleep-disordered breathing ...

Flow limitation/obstruction with recovery breath (FLOW) event for improved scoring of mild obstructive sleep apnea without electroencephalography (Karin Johnson, Douglas Johnson, Robert Thomas, et al.) All Scholarly Works (2018)

OBJECTIVE: Apnea/hypopnea index (AHI), especially without arousal criteria, does not adequately risk stratify patients with mild obstructive sleep apnea (OSA). We describe and test scoring reliability of an event, Flow Limitation/Obstruction With recovery breath (FLOW), ...

Treatment of sleep-disordered breathing with positive airway pressure devices: technology update (Karin Johnson and Douglas Johnson) All Scholarly Works (2015)

Many types of positive airway pressure (PAP) devices are used to treat sleep-disordered breathing including obstructive sleep apnea, central sleep apnea, and sleep-related hypoventilation. These include continuous PAP, autoadjusting CPAP, bilevel PAP, adaptive servoventilation, and ...
