导言 1986年由国家健康研究所举办的婴儿窒息家庭监护讨论会的总结报告中列举了阻抗式窒息监护仪公认的缺点。例如:这些装置不能检测出这种窒息,在窒息的同时产生与心脏活动有关的人为补偿运动以及(或者)在障塞性窒息过程中产生的徒劳无效的呼吸动作。由于低的潮气量呼吸信号而被误检为窒息的检测说明了此类装置的阈值校准方面存在的问题。对阻抗式窒
Introduction The summary report of the Symposium on Infant Suffocation Family held by the National Institutes of Health in 1986 cited the shortcomings recognized by impedance asphyxiation monitors. For example, these devices can not detect such asphyxiation, causing asphyxiation to produce artificial compensatory movement associated with cardiac activity and / or futile and ineffective respiratory action during obstructive asphyxia. Detection of a false positive asphyxiation due to a low tidal volume respiratory signal illustrates the problems with threshold calibration of such devices. Impedance-based stifles
