1.0 Information Technology System Applicable in Nursing Practice

Critical Care Nursing

Is an area of expertise within nursing that focus specifically with human responses to life- threatening problems.

Critical Care Applications

Areas where patients require complex assessment, high- intensity medication, continuous therapy and interventions, and unrelenting nursing attention and continuous watchfulness.

Critical Care Information System

Provide real-time resource utilization data and management of information and access critical care areas through the integration of the medical facilities in the critical care or intensive care unit to an intelligent computer system which is capable of processing all data.

Critical Care Information System

Enables the electronic collection of hospital and patient- specific critical care data of the entire patient in the critical care areas which can be processed to create a patient profile which generate real time and historical report on indicators including bed occupancy, delayed discharges, readmission rates, and outcomes.

Critical Care Information System

Automated collection and management of medical information will become the important task of the __________

ok

• Process store and integrate physiological and diagnostic, information from various sources.

• Present deviations from pre – set ranges by an alarm or an alert.

• Accept and store patient care documentation in a a lifetime’s clinical repository.

• Trend data in a graphical presentations.

• Provide clinical decision support through alerts, alarms and protocols.

• Provide access to vital patient information from any location both inside and outside critical care settings.

• Comparatively evaluate patients from outcomes analysis. Present clinical data based on concept – oriented views.

Microprocessors

Embedded in the device, processes physiological signals after they are amplified, conditioned and digitized

Alerts nursing personnel through a report, an alarm, or a visual notice.

Physiological Monitor

were developed to oversee the vital signs of the astronauts. By the 1970’s these monitors found their way into the hospital setting.

• Sensors

• Signal Conditioner

• File

• Computer Processor

• Evaluation/Controlling Component

Physiologic systems consist of 5 basic parts.

File

rank and order information.

Computer Processor

analyze data and direct reports.

Evaluation/Controlling Component

regulate the equipment or alert the nurse.

Hemodynamic Monitors

Machines under the human machine interface used specifically for the following:

• Measuring Hemodynamic Parameters

• Cardiac output

• Patterns (arrhythmia analysis)

• Vascular system integrity

• Glucose Levels

• Store Waveforms

Automatically transmit selected data to a computerized database.

Thermodilution Technique

The bolus must be injected within 4 seconds. Amount solution must be accurate temperature of the injective. Must be measured and accurately maintained. Catheter must be properly placed.

➢ Computer must have the appropriate computation. Constant bolus must be injected at the appropriate time in the respiratory cycle.

Pulse Oximeter

Co-oximetry

spectrophotometry

A critical piece of hemodynamic information involves the availability of oxygen to bodily tissues. The standard for measurement of blood’s oxygen saturation is ______. _____ is a noninvasive method of measuring oxygen saturation that also uses ________. Light is emitted through a pulsatile arteriolar bed and then detected by photosensor.

• Blood pressure cuff

• Tourniquet

• Air splint (venous pulsations)

• Limits the sensor to distinguish arterial and venous bp

LARGEST CONTRIBUTOR TO ALARMS IN THE ICU CAUSED BY:

Capnography

HEMODYNAMICS

• Continuously assess respiratory gases

telemetry

Hemodynamic monitoring can take place at the bedside of can be conducted from a remote location via ______.

allows for the continuous monitoring of patients usually outside of the ICU.

monitoring is susceptible to signal loss. Remember that computer-based hemodynamic monitoring offers the critical care nurse a wealth of information that does not replace clinical judgment.

Physiologic Monitoring System; Arrhythmia Monitor

Ventricular Fibrillation

Computerized monitoring and analysis of cardiac rhythm have proved reliable and effective in detecting potentially lethal heart rhythms. A key functional element is the system’s ability to detect _________ and respond with an alarm.

• Detection Surveillance Diagnostic

• Interpretive

Arrhythmia Monitor System Types:

• Sensor

• Signal Conditioner

• Cardiographer

• Pattern Recognition

• Rhythm Analysis

• Diagnosis Written Report
