and a threshold time for the trigger. if you set the trigger threshold time to 12 seconds, the monitor triggers an event if the threshold is violated for more than 12 seconds. if you set " on measurement " triggers you can set aperiodic measurements ( such as nbp ) or procedures ( such as cardiac output ) to trigger an event whenever they start. if you set user - defined deviation triggers you can define event triggers that are independent of specific limits and based instead on deviations from the current values. you must set a deviation and a period of time in which the deviation occurs. there are three types of deviation available : any deviation, up deviation where only changes in a positive direction are detected and down deviation where only changes in a negative direction are detected. the deviation can be defined either in relative terms as a percentage, for example 10 %, or as an absolute value, such as 10 bpm. event retriggering if a condition that triggered an event persists and the values remain beyond the trigger threshold, a new event will not be triggered. for a new event to be triggered by the same condition, the measured values for at least one of the triggers must cross back into the normal range and then recross the trigger threshold. event notification advanced you can be notified when an event is detected. for each event group you can define a type of event notification depending on the severity of the event conditions. the notification can be a status surveillance message with a prompt tone or a standard *, * *, or * * * alarm notification. these event alarms are only handled exactly like measurement alarms ; they can be silenced and are also suspended when all alarms are suspended. you should only use alarm notification for events which are comparable in severity to standard measurement alarms to avoid potential confusion due to too many alarms. notification in the form of an alarm is not available when the trigger condition is at least one para @topic:8

( resp ) for the respiratory measurement ( resp ), the monitor measures the thoracic impedance between two ecg electrodes on the patient's chest. changes in the impedance due to thoracic movement produce the resp waveform on the monitor screen. the monitor counts the waveform cycles to calculate the respiration rate ( rr ). lead placement for monitoring resp correct patient skin preparation techniques for electrode placement are important for resp measurement : you will find this information in the chapter on ecg. the resp measurement uses the standard ecg cable sets and lead placements. you can use any of thdifferent types of ecg cable sets - 3 - lead, 5 - lead, 6 - lead or 10 - lead, using either standard or easi™m lacement to measure resp, as long as you use icu ecg cables. the resp signal is always measured between two of the ecg electrodes. if you are using standard ecg electrode placement, resp is measured between the ra and ll electrodes. if you are using easi™ ecg electrode placement, resp is measured between the i and a electrodes. optimizing lead placement for resp if you want to measure resp and you are already measuring ecg, you may need to optimize placement of the two electrodes between which resp will be measured for some patients. repositioning ecg electrodes from standard positions, especially when you are using easi™ ecg electrode placement, results in changes in the ecg waveform and may influence st and arrhythmia interpretation. ardiac overlacardiac activity that affects the resp waveform is called cardiac overlay. it happens when the resp electrodes pick up impedance changes caused by the rhythmic blood flow. correct electrode placement can help to reduce cardiac @topic:8
