Patient monitoring equipment

Patient monitoring equipment

Physiologic monitoring systems continuously measure and display a number of vital signs via electrodes and sensors that are connected to the patient.

They allow continuous monitoring of a range of parameters that include heart rate and heart electrical tracing via an electrocardiogram (ECG), apnea monitors to measure breathing/respiration, oximeters to enable monitoring the oxygen level of the patient's blood, as well as monitors for urine output, intracranial pressure, blood pressure, body temperature and the administered fluids, food and drugs.

Each patient bed in an ICU has a physiologic monitor that measures these body activities and all monitors are networked to a central nurses' station.

Here are the components of patient monitoring systems you’ll need to consider, from pulse oximeter parts to components of an ECG machine:

​PCB card guides

PCB card guides

Horizontal plastic PCB card guides snap in to mount circuit boards in tight spaces. Two tapered ends mean a quick and easy insertion of the PCB from both sides. Side grips hold PCB in place.

Life support equipment

Life support equipment

Intensive care equipment for life support and emergency resuscitation includes the following:

  • ICU ventilator (also called a respirator): assists with or controls pulmonary ventilation in patients unable to breathe on their own. Ventilator parts consist of:
    • A flexible breathing circuit
    • Gas supply
    • Heating/humidification mechanism
    • Monitors and alarms
    They are controlled by a microprocessor and can be programmed to regulate the volume, pressure, and flow of breathing. The monitors and alarms communicate with a central monitoring or information system. The computers in sophisticated ventilator units allow patients to breathe as much as possible for themselves, with the machine helping when necessary. In some cases, the patient breathes with the help of masks, which enables them to avoid sedation and a tube in their windpipe.
  • Suction pump: airway suctioning reduces the risk of:
    • Lung infections
    • Prolonged hypoxia
    • Pooling of secretions
    Mechanically ventilated patients require frequent suctioning. This life-saving procedure must always be available for them.
  • Infusion pump: device that delivers fluids to the patient intravenously or epidurally through a catheter. Automatic, programmable pumping mechanisms provide:
    • Continuous anaesthesia
    • Drugs
    • Blood infusions
    The pump is clamped to an intravenous pole, next to the patient's bed. Your infusion pump components will need to include support for hoses and tubing.
  • Dialysis machine: kidneys filter blood and remove waste products, which produces urine. If kidneys fail, this machine takes over their function, which makes the quality of dialysis machine parts critical. Components of dialysis machines also need support for hoses and tubing.
  • Crash cart: also known as a resuscitation or code cart. This is a movable cart that holds emergency resuscitation equipment for patients whose vital signs are in a dangerous range. The emergency equipment typically contains:
    • Defibrillator
    • Airway intubation devices
    • Resuscitation bag/mask
    • Medication box
    Crash carts are strategically located in the ICU for immediate use when a patient experiences cardiorespiratory failure. The crash-cart components you’ll need include access hardware, handles and fasteners.
  • Intra-aortic balloon pump: a device that helps reduce the heart's workload and aids blood flow to the coronary arteries for patients with:
    • Unstable angina
    • Myocardial infarction (heart attack)

And patients awaiting:

  • Organ transplants

Intra-aortic balloon pumps use a balloon placed in the patient's aorta. The balloon is on the end of a catheter that is connected to the pump's console, which displays heart rate, pressure, and electrocardiogram (ECG) readings. The patient's ECG is used to time the inflation and deflation of the balloon.

Here are the components you’ll need for high-quality life support equipment:

​Twist ties

Diagnostic equipment

Diagnostic equipment

The use of diagnostic imaging equipment – and non-imaging devices – is an increasingly common and essential requirement in the ICU.

  • Scans: Some ICU patients may need further investigation in terms of a computerised tomography scan (CT or CAT scan) or an MRI (Magnetic Resonance Imaging machine) of their head, chest or abdomen. These investigations give detailed radiological pictures which are not possible with a plain x-ray film. Components of CT scan machines and MRI components include fan hardware, cable management, fasteners, PCB and electronics hardware.
  • Ultrasound: increasingly used to assess and guide the management of critically ill patients due to more compact, portable, higher quality and less expensive equipment.
  • Echocardiography (ECG): a scan of the heart to look how it is functioning and guide treatment of the patient using the same principle as an ultrasound. Just a few of the ECG components you’ll need include feet and PCB hardware.
  • Mobile x-ray units: used for bedside radiography, particularly of the chest. Mobile x-ray units use a battery-operated generator that powers an x-ray tube. X-ray machine components range from cable management and fasteners to access solutions.
    The ability to carry out quick examinations by the bedside is a clear advantage in an acute care setting. The ultrasound machine is used to assist the doctor in inserting lines, and also forms an easy and safe investigative tool. A probe is placed on the part of the body to be examined and images are obtained based on the density of the organ such as bone, muscle or a blood vessel. Ultrasound machine parts range from cable management to fasteners.
  • Point-of-care testing: handheld, portable clinical laboratory devices, or point-of-care analysers, are used for blood analysis at the bedside. A small amount of whole blood is required, and blood chemistry parameters can be provided much faster than if samples were sent to the central laboratory. The components you’ll need range from PCB hardware to fasteners.
