PERFORMANCE CHARACTERISTICS
The performance characteristics for Manual Resuscitators will vary from
user to user depending on a variety of factors: ambient temperature,
patient lung compliance, ventilator frequency, size of operator's hands.
The following data has been derived from Manual Resuscitators in accor-
dance with ISO standards.
