3. OUR CASE
52 years old male was admitted in our
CICU with
C/C- severe breathlessness and sweating for
last 5 hours.
4. DEFINITION OF
CRITICALLY ILL
Critical illness is any disease process which
causes physiological instability leading to
disability or death within minutes or hours.
A critically ill patient is one at imminent risk of
death; the severity of illness must be recognized
early and appropriate measures taken promptly
to assess, diagnose and manage the illness.
5. NEED FOR ICU???
To provide appropriate care, specialized
knowledge ,skills and the care delivery
mechanisms needed to evolve to support the
patients' needs for continuous monitoring and
treatment.

7. CRITERIA FOR ICU ADMISSION
Critically ill patients in a medically unstable state
(monitoring and treatment).
Patients requiring intensive monitoring who may also
require emergency interventions.
Patients who are medically unstable or critically ill and
who do not have much chance for recovery due to the
severity of their illness .
Patients who are generally not eligible for ICU admission
because they are not expected to survive.
8. PHILOSOPHY OF MANAGEMENT
Outcome in ICU is predominantly determined by
initial management of patient at risk of life
threatening illness.
“TIME IS TISSUE”
So a prompt and protocolized resusucitation regimen
helps in salvaging these patients.
ASSESSMENT AND MANAGEMENT SHOULD
GO HAND IN HAND
9. PRIORITIES
1. Prompt resuscitation & adhering to advanced
life support guidelines
2. Urgent treatment of life threatening emergencies
such as hypotension, hypoxaemia , hyperkalaemia,
hypoglycaemia and dysrhythmias
3. Analysis of the deranged physiology
4. Establish a complete diagnosis as history &
further diagnostic results are available
5. Careful monitoring of the patient’s condition
and response to treatment
10. What are the steps to be
followed?
1. Initial assessment
2. Immediate management
3. Monitoring
4. Initial investigations

12. OUR CASE – ON EXAMINATION
52-years-old male in acute respiratory distress
Vitals : Temp. 98.8F, HR 120 bpm & regular, RR -
30pm, BP 140/90 mmhg.
He had no cyanosis and clubbing, JVP-Not raised
He was drowsy but easily arousable, oriented
On auscultation, breath sound was diminished
bilaterally, Ronchi throughout bilateral lung fields,
on percussion hyper resonant lung field.
13. STEP 1:
ASSIGN RESPONSIBILITIES
Quickly make a team and assign job
responsibilities to every member clearly and
appropriately.
Initially patient should be seen by a senior
intensivist for initial resuscitation, management,
planning and family briefing.
14. STEP 2: START INITIAL ASSESSMENT
AND RESUSCITATION
Correcting physiological abnormalities should take
precedence over arriving at an accurate diagnosis.
For patients in cardio-respiratory arrest follow
ACLS protocol.
For hemodynamically unstable patients assessment
and management should be simultaneous as per
the clinical clusters “A B C”

16. “B”- BREATHING
Clinical assessment of ventilation and oxygenation (with adjuncts)
C/F of Respiratory Distress:
1. Breathlessness
2. Tachypnea
3. Inability to talk
4. Open mouth breathing
5. Flaring of alae nassi
6. Paradoxical breathing
7. Use of accessory muscles
Respiration
C/F of Inadequate oxygenation:
1. Restlessness
2. Delirium
3. Drowsiness
4. Cool extremities
5. Cyanosis
6. Tachycardia
7. Arrhythmia
8. Hypotension
Clinical presentation of inadequate oxygenation is a late feature of
respiratory failure and imply impending cardio-respiratory arrest.
Patient needs to be identified much earlier and appropriate
management be instituted.
Adjuncts- Pulse Oximetry, ABG
17. “B”- BREATHING(contd...)
ETIOLOGIES TO BE KEPT IN MIND:-
– Tension Pneumothorax
– Pleural Effusion or Hemothorax
– Flail chest
Indications for intubation and mechanical
ventilation:-
– GCS < 8
– Severe hemodynamic instability
– Severe respiratory depression
Non invasive ventilation tried in relatively stable
patients
18. “C”- CIRCULATION
Assessment of adequacy of circulation
– Peripheral and central pulse(rate, rhythm, volume,
symmetry)
– Skin temperature
– Heart rate
– Blood pressure
– Capillary refill
– JVP
– Urine output
Advanced monitoring- bedside ECHO, CVP , IBP,
Cardiac Output.

INFORMANT- PATIENT OR RELATIVES
CHIEF COMPLAINS- CHRONOLOGICAL ORDER
HISTORY OF PRESENT ILLNESS- ELABORATION OF
CHIEF COMPLAINS, ASSOCIATED PROBLEMS, INDICATION
TOWARD A DIFFERENTIAL DIAGNOSIS.
PAST HISTORY- COMORBIDITIES, PREVIOUS SURGERY,
HOSPITALIZATION
PERSONAL HISTORY- ADDICTION
ALLERGY HISTORY
TREATMENT HISTORY & HANDOVER HISTORY
PATIENTS RESUSCITATION STATUS AS PER
FAMILY’S WISH
22. HISTORY- OUR CASE
HOPI-Inability to do daily activities as he becomes short
of breath for last one year.
PH-Stage 1 COPD 4 years back , is not diabetic or
hypertensive but he suffered from bronchitis with upper
respiratory infection for 3 times last year
T/T History-salmetarol+Fluticasone
Personal History- He was a smoker and used to smoke 1
packet per day for 30years(30 pack year) and has quit for
1year.
23. STEP 4- PERFORM FOCUSED PHYSICAL
EXAMINATION
VITALS-BP,PULSE,TEMP,RESPIRATION
EXAMINE FOR PALLOR,CYANOSIS,JAUNDICE,
CLUBBING,PEDAL EDEMA
EXAMINE SKIN FOR
RASH,PETECHIAE,URTICARIA,ESCHAR.
EXAMINE ALL ORGAN SYSTEMS SYSTEMATICALLY
REPEAT EXAMINATIONS FREQUENTLY FOR NEW
FEATURES OR MISSED FINDINGS
IN NEUROLOGICAL PATIENTS,GCS NEEDS TO BE
ASSESSED FREQUENTLY
24. STEP 4- PERFORM FOCUSED
PHYSICAL EXAMINATION cont...
PATIENTS SHOULD BE FULLY EXPOSED WITH
PRIVACY DURING INITIAL EXAMINATION.
WARNING FEATURES OF SEVERE ILLNESS
SBP<90 OR MAP<60 MM HG
GCS<12
PR>150 OR <50 BPM
RR >30 OR<8/MIN
UO<0.5 ML/KG/HR
25. STEP 5-SEND BASIC
INVESTIGATIONS
Send screening investigations during initial
resuscitation
CBC, blood sugar ,electrolytes, urea, creatinine,
LFT, coagulation profile, ABG, Lactate Level in
sepsis patients-initial investigations
Chest x-ray,12 lead ECG
Appropriate microbiology cultures
Further investigations as per history and
examination
26. STEP 5 FOR OUR CASE
A chest radiograph showed hyper inflated lung
field, low and almost flat diaphragm,tubular heart.
ABG showed pH; 7.30, PO2; 62, mmhg PCO2:
64 mm hg HCO3: 29. mmol/l
Normal ECG
27. STEP 5-SEND BASIC
INVESTIGATIONS contd...
In unstable patients investigations should be performed at
bedside as much as possible
To transport outside ICU, patients should be accompanied
by qualified personnel.
Red flag investigations that require immediate corrective
actions
•Blood sugar<80 mg/dl
•Sodium <120 or >150 Meq/l
•Potassium<2.5 or > 6 Meq/l
•pH<7.2
•sPo2<90%
•Bicarbonate <18 mmol/l
28. STEP 6-RECOGNISE THE
PATIENT AT RISK
Special precautions in following groups
Elderly and immuno-compromised(may not
show features of decompensation)
Polytrauma patients(multiple injuries,
distracting pain)
Young adults(decompensation is late due to
physiological reserve)
29. STEP 7-ASSESS RESPONSE TO
INITIAL RESUSCITATION
Assess changes in vital signs with initial
resuscitation-pulse rate, rhythm, BP, oxygen
saturation, urine output, mental state
Continuous assessment is mandatory……one
needs to be vigilant and present at the bed side.
30. STEP 8-ASSESS INTENSITY
OF SUPPORT
Inspired oxygen fraction needed to maintain saturation
above 90%
Intensity of ventilatory support-MV,NIV
dose of vasopressor and ionotrope needed to maintain
MAP >60mmHg
need for volume support to keep adequate urine output
need for BT to keep Hb >8 gm/dl
Need for sedation in agitated patients
Need for dialysis support
31. STEP 9-SEEK HELP FOR
SPECIFIC PROBLEMS THAT MIGHT
REQUIRE EXPERTISE
Cardiologist-complete heart block, acute coronary
syndrome, cardiogenic shock, pericardial tamponade,
massive pulmonary embolism
Nephrologist-dialysis
Neurologist-acute stroke, undiagnosed depressed
conscious level
Neurosurgeon-ICH, head injury, cerebral edema
Trauma surgeon-polytrauma, abdominal trauma, thoracic
trauma
Obstetrician-ruptured ectopic,PPH.
32. STEP 10-CONSTRUCT A WORKING
DIAGNOSIS AND PLAN FOR FURTHER
MANAGEMENT
After initial resuscitation, assessment,and response, a
differential diagnosis should be arrived at.
Reassess the patient frequently to modify initial plan if
needed.
33. STEP 11-BRIEF AND COUNSEL
RELATIVES
After initial assessment, resuscitation,investigations and
response the family and relatives should be briefed about
the likely diagnosis, treatment plan, and approximate
prognosis and duration of stay and consent should be
taken for any invasive procedures.
Family briefing should be documented in clinical notes.
42. OUR CASE MANAGEMENT
Admitting diagnosis - Acute exacerbation of COPD
T/T- O2 2L/min via nasal cannula Goal- O2 saturation 90-
91%,
– Corticosteroid -Hydrocortisone 100 mg 6 hourly,
– Inhaled bronchodilator: Ipratropium bromide and
Salbutamol 4hrly.
– Later on we added aminophylline; initially 6 mg
/kg bolus with in 20 min then 1 mg/kg/hr.
– Antibiotics
– ABGs q 8 hours, CXR.
43. On second day of admission his condition
deteriorated: his distress became more pronounced,
his work of breathing increased significantly
– he became confused
– SpO2 went down 80 to 85% with 5L O2/min,
– ABG showed pH; 7.27, PO2: 55, PCO2, 72,
Hco3: 30,
with the consent of patient's relatives NIV was
added along with the conventional treatment.
44. Patient was kept in close monitoring with hourly
recording of vital signs, conscious level.
Blood gas was measured after 2 hours of
administration of NIV and every 6-hour interval.
There was gradual improvement of patient's
symptoms and blood gas parameter.
Patient was disconnected from ventilator for 10 mins
in every 2 hour and only during feeding.
After 20 hours of NIV patient's clinical condition
significantly improved.
48. Medicine is not the exact science,
I shall use my experience, knowledge
and judgement to its best,
I may go wrong or anything with
patient may go wrong anytime
49. I guarantee nothing but my honest
effort and care for you,
I am not God, but well-trained
professional wanting to take care of
patients
Although the criteria for admission to an ICU are somewhat controversial—excluding patients who are either too well or too sick to benefit from intensive care—there are four recommended priorities that intensivists (specialists in critical care medicine) use to decide this question. These priorities include:
