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 (SpO
2
) 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 (SpO
2
), 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 (SpO
2
)
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

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.
