Read the full statement (205 words)
Use of the Fukuda Denshi DynaScope Model DS-7000 Series Patient Monitor (Model: DS-7000/7000M/7210/7210M) is indicated in those situations where observation of one or more of the following parameters on an individual patient may be required. ECG (waveform, heart rate, ST-Level and ventricular arrhythmias), respiration, non-invasive blood pressure (NIBP), pulse rate, arterial oxygen saturation (SpO2), pulse wave, temperature, invasive blood pressure (IBP), cardiac output, carbon dioxide concentration (CO2), nitrous oxide concentration (N2O), oxygen concentration (O2), and anesthetic agent concentration (AG). The target populations of the system are adult, pediatric, and neonatal patients with the exception of the ST segment and arrhythmia analysis, for which the target populations are adult and pediatric only. These observations can include an audible and visual alarm if any of these parameters exceed values that are established by the clinician. The observations may include the individual or comparative trending of one or more of these parameters over a period of up to 24 hours. The DS-7000 Series Patient Monitor is indicated in situations where an instantaneous display of waveform, numeric and trended values is desired. The DS-7000 Series Patient Monitor is also indicated where a hard copy record of the physiological parameters, the alarms conditions or the trended values may be required.
Indications for use as stated in the FDA summary.
