Measurement item

Maximum intake pressure (hereinafter referred to as PImax)

Maximum expiratory pressure (hereinafter referred to as PEmax)

Measurement mode

S mode = Measure and record PImax or PEmax once.

​

A mode = In accordance with the ATS/ERS standard method, perform at least three measurements and record the minimum value (PImax) or maximum value (PEmax) with a difference of less than 20% as PImax or PEmax.

​

T mode = Repeat inspiration or expiration 10 times in the same manner as measuring PImax or PEmax, and record the average value.

Measurement unit: cmH2O or kPa (1cmH2O=0.098067kPa) Default is cmH2O Measurement range: ±407.9cmH2O (±40kPa)

Allowable pressure: ±815.8cmH2O (±80kPa)

Error range: ±1% FSS (TEB)

TEB=Total Error Band=0°C~50°C total possible errors (offset, full scale span, pressure nonlinearity, pressure hysteresis, pressure non-repeatability, thermal effects on offset, span error range that includes thermal effects (thermal effects, thermal hysteresis).
