ProbTolError {bpAcc}

Probability of tolerable error - AAMI-SP10 standard.

Description

Probability of tolerable error - AAMI-SP10 standard.

Usage

  ProbTolError(distribution = "normal", mu, std.dev, delta)
  

Arguments

distribution

The errors distirbution. Default and only option is "normal".

mu, std.dev

Mean and standar deviation of the average errors distribution (normal).

delta

Maximum average error allowed for the device D.

Details

Computes the probability of tolerable error for a device D for blood pressure measuring under the ANSI/AAMI-SP10 standard for a size-n sample of average errors from a normal distribution with mean mu and stadard deviation sd. The maximum error accepted is 0.85, A tolerable error, according to the ANSI/AAMI-SP10, is a an error of 10mmHg or less on a single person, using the average of that person's readings.

Currently, only normally distirbuted errors are handled. Further choices will be implemented over time.

Fuller details in Chandel, et al. (2022).

Value

It returns the probability of tolerable error based on a normal distribution.
