1 System basics
1.1 Intended use
The BT-740 Patient Monitors acquire the physiological signals such as ECG, respiratory rate, non-invasive blood pressure (NIBP), Invasive Blood Pressure (IBP), blood oxygen saturation (SpO2), temperature. The signals are converted into digital data and processed, examines the data for alarm conditions and display the data. The monitor also provides operating control for the user. 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-740 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), temperature (TEMP), invasive blood pressure (IBP), CO2 and C.O. monitoring. It is equipped with a replaceable built-in battery to provide convenience for the patient movement in hospital.
5) Indications and contraindications

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 ocardiovascular 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.

|
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.

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
