Impact of Supine Versus Semirecumbent Body Posture on the Distribution of Ventilation in Acute Respiratory Distress Syndrome
Autor: Alex K. Pearce, MD, W. Cameron McGuire, MD, MPH, Ann R. Elliott, PhD, Ewan C. Goligher, MD, PhD, G. Kim Prisk, PhD, James P. Butler, PhD, Atul Malhotra, MD
Publikováno v: Critical Care Explorations, Vol 5, Iss 12, p e1014 (2023)
In some patients with acute respiratory distress syndrome (ARDS), a paradoxical improvement in respiratory system compliance (CRS) has been observed when assuming a supine (head of bed [HOB] 0°) compared with semirecumbent (HOB 35–40°) posture. W

Overview of lunar dust toxicity risk
Autor: Michael Pohlen, Danielle Carroll, G. Kim Prisk, Aenor J. Sawyer
Publikováno v: npj Microgravity, Vol 8, Iss 1, Pp 1-9 (2022)
Abstract Lunar dust (LD), the component of lunar regolith with particle sizes less than 20 μm, covers the surface of the Moon. Due to its fineness, jagged edges, and electrostatic charge, LD adheres to and coats almost any surface it contacts. As a

The effect of oxygen and carbon dioxide cross-sensitivity sensor error in the Eco Medics Exhalyzer D device on measures of conductive and acinar airway function
Autor: Jack Bozier, Edward Jeagal, Paul D. Robinson, G. Kim Prisk, David G. Chapman, Gregory G. King, Cindy Thamrin, Sandra Rutting
Publikováno v: ERJ Open Research, Vol 8, Iss 3 (2022)
Introduction The multiple breath nitrogen washout (MBNW) test provides important clinical information in obstructive airways diseases. Recently, a significant cross-sensitivity error in the O2 and CO2 sensors of a widely used commercial MBNW device (

Non-invasive Measurement of Pulmonary Gas Exchange Efficiency: The Oxygen Deficit
Autor: G. Kim Prisk, John B. West
Publikováno v: Frontiers in Physiology, Vol 12 (2021)
The efficiency of pulmonary gas exchange has long been assessed using the alveolar-arterial difference in PO2, the A-aDO2, a construct developed by Richard Riley ~70years ago. However, this measurement is invasive (requiring an arterial blood sample)

The spatial-temporal dynamics of pulmonary blood flow are altered in pulmonary arterial hypertension
Autor: Abhilash S. Kizhakke Puliyakote, G. Kim Prisk, Ann R. Elliott, Nick H. Kim, Beni Pazar, Rui Carlos Sá, Amran K. Asadi, Susan R. Hopkins
Publikováno v: Journal of Applied Physiology. 134:969-979
Using proton MRI-arterial spin labeling to obtain serial images of pulmonary perfusion, we show that global fluctuation dispersion (FDglobal), a metric of temporal fluctuations in the spatial distribution of perfusion, was significantly increased in

Assessing the calculation of conductive and acinar ventilatory heterogeneity indices Scond and Sacin from multiple-breath washout data
Autor: G. Kim Prisk, Sandra Rutting, Jack Bozier, Cindy Thamrin, Paul D. Robinson, Bruce R. Thompson
Publikováno v: Journal of Applied Physiology. 134:879-886
Sensor errors that elevated values of N2 concentration in commercial multiple-breath washout (MBW) devices resulted in errors in calculated parameters including Scond and Sacin. We examined the mechanism of the change in values produced by these erro

Ventilation–perfusion heterogeneity measured by the multiple inert gas elimination technique is minimally affected by intermittent breathing of 100% O2
Autor: Ann R. Elliott, Abhilash S. Kizhakke Puliyakote, Vincent Tedjasaputra, Beni Pazár, Harrieth Wagner, Rui C. Sá, Jeremy E. Orr, G. Kim Prisk, Peter D. Wagner, Susan R. Hopkins
Publikováno v: Physiological Reports, Vol 8, Iss 13, Pp n/a-n/a (2020)
Abstract Proton magnetic resonance (MR) imaging to quantify regional ventilation–perfusion ( V˙A/Q˙) ratios combines specific ventilation imaging (SVI) and separate proton density and perfusion measures into a composite map. Specific ventilation

Small airways dysfunction is associated with increased exacerbations in patients with asthma
Autor: Claire F. O’Sullivan, Kris Nilsen, Brigitte Borg, Matthew Ellis, Pam Matsas, Frank Thien, Jo A. Douglass, Chris Stuart-Andrews, Gregory G. King, G. Kim Prisk, Bruce R. Thompson
Publikováno v: Journal of Applied Physiology. 133:629-636
This study assessed the relationship between peripheral airway function, measured by multiple breath nitrogen washout and oscillometry impedance, and exacerbation history. We found that those with a history of exacerbation in the last year had worse
