Critical Care Nursing

Debbie L. Dempel

history of critical care icu s
History of Critical Care & ICU’s
  • 1930’s – Introduction of Recovery Rooms
  • WWII & Korean War – Concepts of triage and specialty nursing
  • Late 1950’s – beginning of Critical Care Units
  • Early Technology
history continued
History Continued
  • Collaboration between nurses and physicians
  • 1950’s & 1960’s – CV Disease most common diagnosis
  • 1960’s – 30-40% mortality rate for MI
  • 1965 – 1st specialized ICU – The Coronary Care Unit
  • Emergence of Specialized ICU’s

Nursing shortage

Half of patients in ICU’s >65

In US – critical care beds account for 8% of all hospital beds

20% of patients spends time in a critical care unit

Downsizing

Goal: provide high quality, holistic care

Critical Care Technology
the critical care nurse
The Critical Care Nurse
  • “Specialty dealing with human responses to life-threatening problems”
  • Requires Extensive Knowledge and a Continual Desire to Learn
slide9
CCRN
  • Critical Care Certification by AACN
  • Requires:
    • Clinical hours working in an ICU
    • Successful completion of an exam
    • Requires continuing education and clinical hours for recertification
critical care clinical nurse specialist ccns
Critical Care Clinical Nurse Specialist (CCNS)
  • Advanced practice nurse
  • Licensed by the State
  • Five Roles of a CNS:
    • Patient & staff educator
    • Consultant
    • Administrator
    • Researcher
    • Expert practitioner
acute care nurse practitioner acnp
Acute Care Nurse Practitioner (ACNP)
  • Advanced practice nurse
  • Licensed by the State
  • Provides comprehensive care to select critically ill patients
the critical care patient
The Critical Care Patient
  • Physiologically Unstable
  • At Risk for Serious Complications
  • Require Intensive and Complicated Nursing Support and/or Advanced Technology
common problems of critical care patients nutrition
Common Problems of Critical Care Patients - Nutrition
  • Address it early
  • Goal: prevent or correct nutritional deficiencies
  • Parenteral
  • Enteral
common problems of critical care patients anxiety
Common Problems of Critical Care Patients - Anxiety
  • 70-80% of patients
  • Indicators – agitation, increased BP, increased HR, verbalization, restlessness
  • Treatment
common problems of critical care patients pain
Common Problems of Critical Care Patients - Pain
  • 70% reported moderate to severe pain
  • 5th vital sign
  • Leads to anxiety, agitation, increased myocardial oxygen consumption, delays wound healing
common problems of critical care patients impaired communication
Common Problems of Critical Care Patients – Impaired Communication
  • Patient on the ventilator
  • Use of medications
  • Nursing Interventions
common problems of critical care patients sensory perceptual problems
Common Problems of Critical Care Patients – Sensory-Perceptual Problems
  • “ICU Psychosis” – Really Delirium
  • 15-40% of patients
  • Alteration in mentation
  • Psychomotor behavior
  • Alterations in sleep
  • Predisposing factors
common problems of critical care patients sleep deprivation
Common Problems of Critical Care Patients – Sleep Deprivation
  • Poor sleep/wake cycles
  • Lack of REM sleep
  • Predisposes patients for delirium
  • Treatment
family need of the critical care patient
Family Need of the Critical Care Patient
  • Information – major source of anxiety and litigation
  • Reassurance – can reassure care is being given
  • Convenience – access to the patient
arterial lines
Arterial Lines
  • Catheter placed in an artery
  • Pressure from the artery is transmitted to a transducer by a column of fluid and converted in a pressure tracing
  • Transducer must be placed at the Phlebostatic Axis – 4th intercostal space
  • Radial artery is the most common site
arterial lines waveform
Arterial Lines - Waveform
  • Systole – aortic valve opens, blood ejected from LV, sharp rise in waveform
  • Dicrotic Notch – closure of the aortic valve, signifies the beginning of diastole
  • Diastole – lowest point recorded on the waveform
pulmonary artery catheter swan ganz catheter
Pulmonary Artery Catheter (Swan-Ganz Catheter)
  • Evaluate heart disease, shock states, compromised CO, and fluid status
  • Also used to evaluate a patient’s response to treatment
  • Catheter placed through a central vein to the right atrium, right ventricle, and into the pulmonary artery
pulmonary artery catheter swan ganz catheter25
Pulmonary Artery Catheter (Swan-Ganz Catheter)
  • Measures Intracardiac Pressures
  • Measures Cardiac Output
  • Able to Obtain Mixed Venous Blood Samples
pulmonary artery catheter swan ganz catheter26
Pulmonary Artery Catheter (Swan-Ganz Catheter)
  • Pulmonary Artery Port
  • Central Venous Port
  • Injectate Port
  • Thermister Connection
  • Balloon Inflation Valve
preload
Preload
  • Volume within a cardiac chamber at the end of diastole
  • Pulmonary Capillary Wedge Pressure – estimates the left ventricular end-diastolic pressure, 6-12 mm Hg
  • Central Venous Pressure – right ventricular end-diastolic pressure, 2-8 mm Hg
afterload
Afterload
  • Refers to the forces that oppose ventricular ejection
  • Systemic arterial pressure, resistance of the aortic valve, and mass and density of the blood
  • Systemic Vascular Resistance
cardiac output
Cardiac Output
  • Volume of blood pumped by the heart in 1 minute
  • Normal: 4-8 L/minute
  • Doesn’t take into account body size
  • More specific is Cardiac Index – size adjusted by Body Surface Index
intraaortic balloon pump iabp
Intraaortic Balloon Pump (IABP)
  • Balloon Catheter placed in the descending thoracic aortic arch
  • Balloon inflation timed to begin to inflate at the time the aortic valve closes – time of early diastole – dicrotic notch
slide33
IABP
  • Augments aortic pressure and forward flow
  • Increases coronary perfusion
  • When balloon deflates at end of diastole and aortic valve opens negative pressure pulls blood forward
slide34

A: Systole-balloon

Deflated, facilitates

Ejection of blood to

Periphery

B: Early diastole –

Balloon begins to

Inflate

C: Late diastole –

Balloon is totally

Inflated, augments

Aortic pressure &

Increases coronary

perfusion
