The Penh index represents the OVA-induced AHR to methacholine, which was measured in mice from control, asthma, vehicle-treated, and suramin-treated groups using a body
plethysmograph. Values represent the means [+ or -] SEM (n = 3~5).
During exposure, clean or irritant-laden air was drawn into the headspace of the double
plethysmograph at a flow rate of 1 L/min.
SBP was measured by the indirect method and measurements were taken weekly by means of a tail-cuff
plethysmograph (Model IITC 31, Woodland Hills, CA - USA) using software supplied by the manufacturer.
The assessment tools utilized include the STATIC-99R, STABLE 2007, penile
plethysmograph (PPG), and sexual history polygraph.
Although non-invasive ABP measurement technique (Finapres
plethysmograph) might be used for CA assessment [22], the invasive ABP sensors are more often used in clinical practice.
Spirometry including reversibility test was performed maintaining ATS recommendation on Elite Series Body
Plethysmograph (Make- Medical Graphics Corporation, USA; Software- Breeze Suite Version 6.2C).
The rat was tracheal cannulated after anesthetized with urethane (40 mg/kg), then placed in a whole-body
plethysmograph for the measurement of lung resistance (RL) and lung dynamic compliance (Cdyn) with a real-time data analysis system (MedLab Biological Signal Collection System V 5.0, Medease Scientific Technic Co.
To analyze the AHR, methacholine-induced airflow obstructions from conscious mice that were placed in a whole body
plethysmograph (model PLY 3211, Buxco Electronics, Troy, NY, USA) were performed, and the dimensionless parameter known as enhanced pause (Penh) was measured as previously described [19].
The paw volume was measured at half an hour after the injection using a
plethysmograph by dipping the foot in the mercury bath of the
plethysmograph apparatus up to the anatomical hairline on lateral malleolus.

plethysmograph variation and its relationship to the arterial waveform in mechanically ventilated children," Journal of Clinical Monitoring and Computing, vol.
Thoracoabdominal
plethysmograph, oronasal temperature thermistor, and nasal-cannula pressure transducer system were used to identify apneas and hypopneas.
