1 System basics
1.1 Intended use
The BT-780 Patient Monitors acquire the physiological signals such as ECG, respiratory rate, non-invasive blood pressure (NIBP),
blood oxygen saturation (SpO2) and temperature. The signals are converted into digital data and processed, examines the data for
alarm conditions and display them. The patient monitor intend to use in hospital clinical area such as intensive care units, cardiac
care units, operating room, emergency department, to provide additional information to the medical and nursing staff about the
physiological condition of the patient. The BT-780 patient monitors are intended to be used only under regular supervision of
clinical personnel. It is suitable for adult and pediatric, neonate. The intended locations of use are hospitals and clinics.
1) Intended patient population
-Adult (>18 years adults) and Pediatrics (30 days < and <18 years) and Neonate (0 days＜and ＜30days)
2) Intended user profile
-Doctor, physicians or nursing staff who is qualified personnel
-Basic experiences or knowledge on medical field, especially on patient monitoring
-Trained or requested to read IFU before use
3) Environment of use
-Hospital and clinic
-Requirements: Stable power source
4) Scope of application
This monitor is suitable for bedside monitoring of patient. This monitor enables ECG, respiration (RESP), pulse rate (PR), blood
oxygen saturation (SpO2), noninvasive blood pressure (NIBP) and temperature (TEMP) monitoring. It is equipped with a replaceable
built-in battery to provide convenience for the patient movement in hospital.
5) Indications and contraindications
Blood oxygen saturation (SpO2)
Indication:
- Monitoring effectives of oxygen therapy
- A reading is needed to facilitate the completion of an early warning score to inform clinical assessment
- Sedation or anesthesia
- Transport of patients who are unwell and require oxygenation assessment
- Haemodynamic instability (e.g. cardiac failure or Myocardial Infarction)
- Respiratory illness e.g. asthma, chronic obstructive pulmonary disease
- Monitoring during administration of respiratory depressant drugs, e.g. opiate epidural or patient-
controlled analgesia.
- Assessing oxygen saturation during physical activity e.g. in pulmonary rehabilitation
Contraindications
- Pulse oximetry does not give an indication of haemoglobin so if the patient is profoundly anaemic then
their oxygen saturation may by normal but they may still be hypoxic
Source: NHS. “Clinical Procedure_ Procedure for Pulse Oximetry/SPO2”. Wirral Community NHS Trust. Sep, 2013
Non-invasive blood pressure (NIBP)
Indication:
- To determine a patient’s blood pressure
- Screen for hypertension
- Following the effect of anti-hypertensive treatments in a patient to optimize their management
- Assessing a person’s suitability for a spot or certain occupations
- Estimation of cardiovascular risk
- Determining for the risk of various medical procedure
- Figuring out whether a patient is clinically deteriorating or is at risk.
Contraindications
- Oscillometric blood pressure devices may not be accurate in patients with weak or thready pulse
- In patients with heart beats below 50 beats/minutes, even if the rhythm is regular, some of the semi-
automatic devices are unable to reduce their deflation rate sufficiently so that too rapid a falling in cuff
pressure results in underestimation of systolic blood pressure and overestimation of diastolic blood
pressure.
- Do not apply to limb with AV fistula, significant injury or burn, or lymph node removal post mastectomy.

Electrocardiography (ECG)
Indication:
- The electrocardiogram (ECG) has proven to be among the most useful diagnostic test in clinical medicine.
It is routinely used in the evaluation of patients to detect myocardial injury, ischemia and the presence
of prior infarction, in the assessment of patients with electrolyte abnormalities, drug toxicities and
implanted defibrillators and pacemakers.

- In addition to its usefulness in the evaluation of ischemic coronary disease, the ECG, in conjunction with
ambulatory ECG monitoring, is of particular use in the diagnosis of disorders of the cardiac rhythm and in
the evaluation of syncope. Other common uses of the ECG include the assessment of metabolic
disorders and side effects of pharmacotherapy, as the evaluation of primary and secondary
cardiomyopathic processes, among others.
Contraindications
- No absolute contraindications to performing an ECG exist, other than patient refusal. Some patients may
have allergies or, more commonly, sensitivities to the adhesive used to affix the leads; in these cases,
hypoallergenic alternatives are available from various manufacturers.
Source: Tarek, A. “Electrocardiography”,<Medscape>, Apr 17, 2017
Temperature (TEMP)
Indication:
- To obtain the baseline temperature to enable comparisons to be made with future recordings
- To enable close observation in resolving hypothermia/hyperthermia
- To observe and monitor patients for changes indicating an infection
- To monitor the effect of treatment for antimicrobial therapy for infection
- Using before and during a blood transfusion to monitor for signs of a reaction
Contraindications
- No known contraindications

1.8 Essential performance
This device Multi-parameter Patient Monitor provides various patient vital signs such as pulse rate, ECG, respiration, blood oxygen
saturation, blood pressure and temperature by placing or inserting the various sensors to the appropriate site of patient. The device
is composed with display and control circuit, and input part for various sensors. It detects ECG, SpO2, NIBP, etc. using ECG cable and
specific probes and sensors. The detected analog signal amplifies and converted to digital. This concerted data feed to the CPU and
converted to the display format as number and waveform. This device is incorporated with alarm system. The alarm generated
when the detected signal range is beyond the user set alarm limits.

4 Patient information management
Connect the patient to the monitor, and the monitor will display and store the physiological data of the patient, so the patient can
be monitored without admitting the patient. However, admitting the patient correctly is very important.
If the monitor has admitted the patient, it is recommended to operate the monitor to discharge the current patient before
connecting to (not admitted) the next patient. Otherwise, the data of the previous patient will be stored in the data of the current
patient.
WARNING

Whether the patient is admitted or not, the system will give a default value to “Patient Type” and “Pace Maker”,
“Patient Type” default “Adult”, “Pace Maker” default “No”, and the user must confirm that the default value is
appropriate for the patient being monitored.
For patients with pacemakers, “Pace Maker” must be set to “Yes”. Otherwise, the pacing pulse will be treated as
normal QRS wave group, and the system is unable to detect the alarm status of “ECG Signal weak”.
For patients without a pacemaker, “Pace Maker” must be set to “No”. Otherwise, the system is unable to detect
the arrhythmias (including PVCs count) related to ventricular premature beats, and fails to perform ST segment
analysis.
