DEFINITIONS

CRITICAL CARE : CRITICAL CARE IS A TERM USED TO DESCRIBE AS THE CARE OF PATIENTS WHO ARE EXTREMELY ILL AND WHOSE CLINICAL CONDITION IS UNSTABLE OR POTENTIALLY UNSTABLE.

3Prof. Dr. R S Mehta, BPKIHS

Page 4: Critical care   design and facilities

CRITICAL CARE UNIT :IT IS DEFINED AS THE UNIT IN WHICH COMPREHENSIVE CARE OF A CRITICALLY ILL PATIENT WHICH IS DEEMED TO RECOVERABLE STAGE IS CARRIED OUT.

4Prof. Dr. R S Mehta, BPKIHS

Page 5: Critical care   design and facilities

CRITICAL CARE NURSING :IT REFERS TO THOSE COMPREHENSIVE, SPECIALIZED AND INDIVIDUALIZED NURSING CARE SERVICES WHICH ARE RENDERED TO PATIENTS WITH LIFE THREATENING CONDITIONS AND THEIR FAMILIES.

Historical Background

Page 8: Critical care   design and facilities

World War II Shock wards

established for resuscitation

Transfusion practices in early stages

After World war-II, nursing shortage forced grouping of postoperative patients in recovery areas

8Prof. Dr. R S Mehta, BPKIHS

Page 9: Critical care   design and facilities

Polio epidemic 1950’s: use of

mechanical ventilation (“iron lung”) for treatment of polio

Development of respiratory intensive care units

At the same time, general ICU’s developed for sick and postoperative patients

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

ICU’s also treat the dying Isaac Asimov:

“Life is pleasant. Death is peaceful. It is the transition that is difficult”

An Ideal ICU

13Prof. Dr. R S Mehta, BPKIHS

Page 14: Critical care   design and facilities

Multidisciplinary & Collaborative approach to ICU care Medical & nursing directors : co-responsibility for ICU management• a team approach : doctors, nurses, R/T, pharmacist• use of standard, protocol, guideline consistent approach to all issues• dedication to coordination and communication

for all aspects of ICU management• emphasis on research, education, ethical

issues, patient advocacy14Prof. Dr. R S Mehta, BPKIHS

Page 15: Critical care   design and facilities

CLASSIFICATION OF CRITICAL CARE PATIENTS

Level O : normal ward care Level 1: at risk of deteriorating , support

from critical care team Level 2 : more observation or

intervention, single failing organ or post operative care

Level 3; advanced respiratory support or basic respiratory support ,multiorgan failure 15Prof. Dr. R S Mehta, BPKIHS

Page 16: Critical care   design and facilities

Types of ICU General Medical Intensive Care Unit(MICU) Surgical Intensive Care Unit Medical Surgical Intensive Care Unit(MSICU)

Specialized Neonatal Intensive Care Unit(NICU) Special Care Nursery(SCN) Paediatric Intensive Care Unit(PICU) Coronary Care Unit(CCU) Cardiac Surgery Intensive Care Unit(CSICU) Neuro Surgery Intensive Care Unit(NSICU) Burn Intensive Care Unit(BICU) Trauma Intensive Care Unit

DESIGN OF ICU

Prof. Dr. R S Mehta, BPKIHS 17

Page 18: Critical care   design and facilities

ORGANIZATION OF ICU DESIGN OF ICU : 1. Should be at a geographically distinct area

within the hospital, with controlled access.2. There should be a single entry and exit.

However, it is required to have emergency exit points in case of emergency and disaster.

3. There should not be any through traffic of goods or hospital staff. Supply and professional traffic should be separated from public/visitor traffic. 18Prof. Dr. R S Mehta, BPKIHS

Page 19: Critical care   design and facilities

4. Safe, easy, fast transport of a critically sick pt should be a priority in planning its location. Therefore, the ICU should be located in close proximity or ER, OT, trauma ward etc.

5. Corridors, lifts and ramps should be spacious enough to provide easy movement of bed/trolley of a critically sick patient.

6. Close, easy proximity is also desirable to diagnostic facilities, blood bank, pharmacy etc.

BED STRENGTH:1. It is recommended that total bed strength in ICU

should be between 8-12 and not less than 6 or not more than 24 in any case.

19Prof. Dr. R S Mehta, BPKIHS

Page 20: Critical care   design and facilities

2. 3-5 beds per 100 hospital beds for a Level III ICU or 2 to 20% of the total no of hospital beds.

3. 1 isolation bed for every ICU beds.

BED AND ITS SPACE:1. 150-200 sq.ft per open bed with 8 ft in between

beds.2. 225-250 sq.ft per bed if in a single room.3. Beds should be adjustable, no head board, with

side rails and wheels.4. Keep bed 2 ft away from head wall.

20Prof. Dr. R S Mehta, BPKIHS

Page 21: Critical care   design and facilities

ACCESSORIES:1. 3 O2 outlets, 3 suction outlets (gastric, tracheal

and underwater seal), 2 compressed air outlets and 16 power outlets per bed.

2. Storage by each bedside.3. Hand rinse solution by each bedside.4. Equipment shelf at the head end.5. Hooks and devices to hang infusions/ blood

bags, extended from the ceiling with a sliding rail to position.

6. Infusion pumps to be mounted on stand or poles.7. Level II ICUs may require multi channel invasive

monitors. 21Prof. Dr. R S Mehta, BPKIHS

Page 22: Critical care   design and facilities

8. ventilators, infusion pumps, portable X ray unit, fluid and bed warmers, portable light, defibrillators, anaesthesia machines and difficult airway management equipments are necessary.

STAFFING :1. Medical Staff – the best senior medical staff to

be appointed as an Intensive Care Director or Intensivist. Less preferred are other specialists from anaesthesia / medicine who has clinical commitment elsewhere. Junior staff are intensive care trainers and trainees on deputation from other disciplines.

2. Nursing staff – The major teaching tertiary care ICU requires trained nurses in critical care. 22

Page 23: Critical care   design and facilities

The no of nurses ideally required for such unit is 1:1 ratio, however it might not be possible to have such members in our set up. So 1 nurse for 2 patients is acceptable. The no of trained nurses should also be worked out by the type of ICU, the workload and work statistics and type of patient load.

3.Allied Services – Respiratory services, Nutritionist, Physiotherapist, Biomedical engineer, technicians, computer programmer, clinical pharmacist, social worker / counsellor and other support staff, guards and grade IV workers.

23Prof. Dr. R S Mehta, BPKIHS

MONITORING IN CRITICAL CARE AREAS…

Airway monitoring Keep talking to your patient

Breathing check Don’t forget to auscultate your patient

Circulation monitoring When in doubt check bilateral limb BP and radio-femoral delay

Disability(neurological monitoring) Keep an eye when your patients walking

Expose and look for problems Keep an eye on all tubes and wires

Pain management is must

Guidelines for monitoring the patients in ICU: Discuss

Decrease anxiety & fear: reassure, sedation Assess: all physiological parameters Inspect & examine pt.: LOC, secretions etc. Vitals : TPR BP RR HR Pao2, paco2, urine output Weight gain Capillary refill: 3-5 sec Phy. Exam: head to toe & systematic ETT, Airway, subcutaneous emphysema, chest tube, Skin temp, gastric distention All relevant Laboratory reports: ABG, BUN, LFT etc.

Role of Nurses in ICU

67Prof. Dr. RS Mehta, BPKIHS

Page 68: Critical care   design and facilities

ICU nurses play a vital role in the patient’s care, including the following:

Taking regular blood tests Changing the patient’s treatment in line with test results Giving the patient the drugs and fluids that the doctors

have prescribed Recording  a patient’s blood pressure, heart rate and

oxygen levels Clearing fluid and mucus from the patient’s chest using

a suction tube Turning the patient in his or her bed every few hours to

prevent sores on the skin

68Prof. Dr. RS Mehta, BPKIHS

Page 69: Critical care   design and facilities

Contd… Cleaning the patient’s teeth and

moistening the mouth with a wet sponge Washing the patient in bed Changing the sheets Changing a patient’s surgical stockings,

which help circulation when he or she is inactive (lying still) for a long time

Putting drops in the patient’s eyes to make it easier to blink

69Prof. Dr. RS Mehta, BPKIHS

Page 70: Critical care   design and facilities

Nurses role to patient with CVP Position the patient in Semi Fowler position. Removes clothing that could constrict the

neck or upper chest Provide adequate lightening to visualize

effectively the external jugular veins. Prevent the infection from the ports by

change dressing.

70Prof. Dr. RS Mehta, BPKIHS

Page 71: Critical care   design and facilities

Contd… Label the date of insertion and change. Observe for complication such as

pneumothorax, hemothorax, hematoma, cardiac tamponade, air embolism and colonization of micro-organism.
