• Sickest patients (multiple diagnosis, multi organ failure, immunocompromised, septic and trauma)
• Move less
• Malnourished
• More obtunded (Glasgow coma scale)
• May be associated Diabetics and Heart failure
“Repeated or continuous observations or measurements
of the patient, physiological function, and the function
of life support equipment, for the purpose of guiding
management decisions, including when to make
therapeutic interventions, and assessment of those
interventions”
A patient monitor may not only alert caregivers to
potentially life-threatening events; many provide
physiologic input data used to control directly
connected life-support devices.
There are at least four categories of patients who need physiologic monitoring:
1. Patients with unstable physiologic regulatory systems; for example, a patient
whose respiratory system is suppressed by a drug overdose or anesthesia.
2. Patients with a suspected life-threatening condition; for example, a patient who has
findings indicating an acute myocardial infarction (heart attack).
3. Patients at high risk of developing a life-threatening condition; for example,
patients immediately post open-heart surgery, or a premature infant whose heart and
lungs are not fully developed.
4. Patients in a critical physiological state; for example, patients with multiple trauma
or septic shock.

◦ Size◦ Reactivity◦ Equality
Cerebral perfusion pressure (>70mmHg)◦ CPP = MAP- ICP
Intracranial pressure (<10mmHg)
Mixed venous saturation◦ Measured with PA catheter◦ Normal is 65-75%◦ Low SvO2 may indicate inadequate tissue O2 delivery (even if arterial O2 is OK)
Lactates◦ Increased lactate concentration and metabolic acidosis suggests
anaerobic metabolism and inadequate tissue oxygenation. lactate also increases with liver failure and sepsis,
ABG monitoring◦ Monitors acid-base balance, PaO2, and PaCO2
Gastric tonometry Used to detect shock-induced splanchnic ischemia by measure gastric luminal PCO2
and deriving the mucosal pH
PA catheter TEE JVP CO monitor
NM- monitor: standard method of monitoring drug induced NM block is to apply a series of four low frequency(2Hz) electrical pulse to ulnar nerve at forearm, and observe for adduction of thumb.
Total absence of thumb adduction is evidence of excessive block. Desired goal is 1or 2 preceptible twitches, and drug infusion is
adjusted to achieve end point.
Capnography◦ End-tidal CO2 concentration is close to artrial PaCO2 levels◦ Indicates the adequacy of alveolar ventilation
Pain scoring Spirometry Plasma level of various drugs X-ray chest
Global measures◦ Reflect the adequacy of total tissue perfusion but could be
normal with local perfusion abnormalities◦ SvO2 <55% indicates global tissue hypoxia.
Organ-specific Measures◦ Urine flow
A sensitive indicator of renal perfusion provided the kidneys aren’t damaged
Normal is 1ml/kg
◦ Core-peripheral temperature The gradient between peripheral (skin) temp and core
(rectal) is often used as an index of peripheral perfusion The less perfusion, the colder the periphery

1- Acute respiratory failure due to:
Mechanical failure, includes neuromuscular diseases as Myasthenia Gravis, Guillain-Barré Syndrome, and Poliomyelitis (failure of the normal respiratory neuromuscular system)
Musculoskeletal abnormalities, such as chest wall trauma (flail chest)
Infectious diseases of the lung such as pneumonia, tuberculosis.
2- Abnormalities of pulmonary gas exchange as in:
Obstructive lung disease in the form of asthma, chronic bronchitis or emphysema.
Conditions such as pulmonary edema, atelectasis, pulmonary fibrosis.
Patients who has received general anesthesia as well as post cardiac arrest patients often require ventilatory support until they have recovered from the effects of the anesthesia or the insult of an arrest.

Negative-pressure ventilators
Early negative-pressure ventilators were known as “iron lungs.”
The patient’s body was encased in an iron cylinder and negative pressure was generated .
Intermittent short-term negative-pressure ventilation is sometimes used in patients with chronic diseases.
The iron lung are still occasionally used today.
Positive-pressure ventilators are deliver gas to the patient under positive-pressure, during the inspiratory phase.
A- Volume Modes1- Assist-control (A/C)
2- Synchronized intermittent mandatory ventilation (SIMV)
B- Pressure Modes
1. Pressure-controlled ventilation (PCV) 2- Pressure-support ventilation (PSV)
3- Continuous positive airway pressure (CPAP)
4- Positive end expiratory pressure (PEEP)
5- Noninvasive bilevel positive airway pressure ventilation (BiPAP)
ventilator provides the patient with a pre-set tidal volume at a pre-set rate .
Patient may initiate a breath on his own, but the ventilator assists by delivering a specified tidal volume to the patient. pt can initiate breaths that are delivered at the preset tidal volume.
Pt. can breathe at a higher rate than the preset number of breaths/minute.
The total respiratory rate is determined by the number of spontaneous inspiration initiated by the patient plus the number of breaths set on the ventilator.
In A/C mode, a mandatory (or “control”) rate is selected.
If the patient wishes to breathe faster, pt. can trigger the ventilator and receive a full-volume breath.
Often used as initial mode of ventilation
When the patient is too weak to perform the work of breathing (e.g., when emerging from anesthesia).
Disadvantages:
Hyperventilation,
The ventilator provides the patient with a pre-set number of breaths/minute at a specified tidal volume and FiO2.
In between the ventilator-delivered breaths, the patient is able to breathe spontaneously at his own tidal volume and rate with no assistance from the ventilator.
However, unlike the A/C mode, any breaths taken above the set rate are spontaneous breaths taken through the ventilator circuit.
The tidal volume of these breaths can vary drastically from the tidal volume set on the ventilator, because the tidal volume is determined by the patient’s spontaneous effort.
Adding pressure support during spontaneous breaths can minimize the risk of increased work of breathing.
Ventilators breaths are synchronized with the patient spontaneous breathe( no fighting).
Used to wean the patient from the mechanical ventilator.
Weaning is accomplished by gradually lowering the set rate and allowing the patient to assume more work
Ingento EP & Drazen J: Mechanical Ventilators, in Hall JB, Scmidt GA, & Wood LDH(eds.): Principles of Critical Care
Ventilation is completely provided by the mechanical ventilator with a preset tidal volume, respiratory rate and oxygen concentration
Ventilator totally controls the patient’s ventilation i.e. the ventilator initiates and controls both the volume delivered and the frequency of breath.
Client does not breathe spontaneously.
Client can not initiate breathe
The PCV mode is used
◦ If compliance is decreased and the risk of barotrauma is high.
◦ It is used when the patient has persistent oxygenation problems despite a high FiO2 and high levels of PEEP.
The inspiratory pressure level, respiratory rate, and inspiratory–expiratory (I:E) ratio must be selected.
Sedation and the use of neuromuscular blocking agents are frequently indicated, because any patient–ventilator asynchrony usually results in profound drops in the SaO2.
This is especially true when inverse ratios are used. The “unnatural” feeling of this mode often requires muscle relaxants to ensure patient–ventilator synchrony.
Inverse ratio ventilation (IRV) mode reverses this ratio so that inspiratory time is equal to, or longer than, expiratory time (1:1 to 4:1).
Inverse I:E ratios are used in conjunction with pressure control to improve oxygenation by expanding stiff alveoli by using longer distending times, thereby providing more opportunity for gas exchange and preventing alveolar collapse.
The patient breathes spontaneously while the ventilator applies a pre-determined amount of positive pressure to the airways upon inspiration.
Pressure support ventilation augments patient’s spontaneous breaths with positive pressure boost during inspiration i.e. assisting each spontaneous inspiration.
Helps to overcome airway resistance and reducing the work of breathing.
Indicated for patients with small spontaneous tidal volume and difficult to wean patients.
Patient must initiate all pressure support breaths.
Pressure support ventilation may be combined with other modes such as SIMV or used alone for a spontaneously breathing patient.
The patient’s effort determines the rate, inspiratory flow, and tidal volume.
In PSV mode, the inspired tidal volume and respiratory rate must be monitored closely to detect changes in lung compliance.
It is a mode used primarily for weaning from mechanical ventilation.
Constant positive airway pressure during spontaneous breathing
CPAP allows the nurse to observe the ability of the patient to breathe spontaneously while still on the ventilator.
CPAP can be used for intubated and nonintubated patients.
It may be used as a weaning mode and for nocturnal ventilation (nasal or mask CPAP)

Prevent atelactasis or collapse of alveoli
Treat atelactasis or collapse of alveoli Improve gas exchange & oxygenation Treat hypoxemia refractory to oxygen therapy.(prevent

Treat pulmonary edema ( pressure help expulsion of fluids from alveoli
BiPAP is a noninvasive form of mechanical ventilation provided by means of a nasal mask or nasal prongs, or a full-face mask.
The system allows the clinician to select two levels of positive-pressure support:
An inspiratory pressure support level (referred to as IPAP)
An expiratory pressure called EPAP (PEEP/CPAP level).
1- T-piece trial,
2- Continuous Positive Airway Pressure (CPAP) weaning,
3- Synchronized Intermittent Mandatory Ventilation (SIMV) weaning,
4- Pressure Support Ventilation (PSV) weaning.

◦ LMWH decrease incidence of DVT by 30% over UFH.
Type of fluid that is best designed to correct a specific problem with fluid balance is:
Crystalloid fluids are designed to fill extracellular space are would be use in pt. With dehydration, (loss of interstitial &intravascular fluid).
Colloid fluid are designed to expand the plasma volume and are appropriate for pt. With hypovolemia due to blood loss.
Albumin containing colloid fluid are appropriate for pt. With hypovolemia associated with hypoalbuminemia.
Regular oral and teeth cleaning should be done at lest 12 hrly. Prevent aspiration
1. Positioning—lateral position with head turned to the side or side-lying. Position back of head on a pillow so that the face tips forward and fluid/ secretions will flow out of the mouth, not back into the throat.
Place a bulb syringe or suction machine with suction equipment nearby.
Care of eyes: Clean from inner to outer conthus with wet (normal saline), warm
cotton ball or compress. Use artificial tear solution or normal saline every four hour, if blink
reflex is absent. Care for eye glass, contact lens.
Repositioning the ETT move it to a different location on the patient’s mouth avoiding areas of breakdown and ulceration.
Skin preparation is required when using tapes or devices with adhesives. This may include:
-Shaving (consent may be required before shaving), cleaning and drying. - Preparation with skin prep solutions such antiseptic.
If an ETT requires advancing or withdrawing, the patient’s oral airway should be suctioned and then the cuff deflated prior to moving the ETT.
ETT cuff pressure is monitored to minimize the risk of tracheal necrosis and to reduce aspiration of oral secretions into the airway.
Cuff pressure should be monitored at least every four hours.
ETT cuff pressure should be maintained at a minimum of 25 cmH2O to reduce the risk of secretions leaking into the trachea and bronchi.
Maximum cuff pressure is 30 cmH20 to avoid the risk of tracheal necrosis.
The measuring device connects to the one way valve of the ETT pilot balloon and the pressure is read at end of inspiration.
ETT suctioning should be performed at least 4-6hrly to ensure airway patency.
Perform hand hygiene prior to using the in-line suction.
Always wear gloves and eye protection.
Suctioning is the mechanical aspiration of pulmonary secretions from a patient with an artificial airway in place.
Indications◦ Inability to cough effectively◦ Sputum plugging
To assess tube patency
Contraindication Frank haemoptysis Severe brochospasm Undrained pneumothorax Compromised cardiovascular system
The suction catheter used must be less than half the diameter of endotracheal tube.
The vacuum pressure should be as low as possible. (60-150mmHg)
Suction should never be routine, only when there is an indication
Hazards of suctioning Mucosal trauma Cardiac arrhythmias Hypoxia Raised intracranial pressure
To be given every four hours

Inner cannula of metal tracheostomy -cleaned under running water
-immersed in hydrogen peroxide for 10mts
- washed with water and gauze wick -boiled for 10 mints and replaced once It is cool
Nosocomial infections◦ occur in approximately 10% of ICU patients at a rate of
21 to 25 infections per 1000 ICU patient-days.
◦ The most common nosocomial infections in medical ICUs are urinary tract infections (31%), followed by pneumonia (27%) and primary bloodstream infections (19%).
VAP is defined as pneumonia developing in mechanically ventilated patients after more than 48 hours of intubation, with no clinical evidence suggesting the presence or probable development of pneumonia at the time of initial intubation.
VAP is a leading cause of morbidity and mortality in mechanically ventilated, critically ill patients.
The incidence of VAP is estimated to be 10% to 25%, and the estimated mortality rate from VAP is 5% to 27%. VAP also increases hospital length of stay and cost.
The diagnosis of VAP is challenging. presumptive diagnosis of pneumonia is made when fever, leukocytosis, purulent secretions, and a new infiltrate on chest radiography develop and when bacteria are isolated by nonquantitative analysis of endotracheal aspirates.
These nonspecific diagnostic criteria may lead to unnecessary antibiotic use, increased hospital cost, emergence of resistant microorganisms, and a potential delay in diagnosis of the true cause of the fever.
Host Factors Factors that facilitate reflux& aspiration into the lower RT
• Elderly• Severe Illness• Underlying Lung Disease - Mechanical ventilation• Depressed Mental Status - Tracheostomy• Immunocompromising - Use of a Nasogastric
TubeConditions or Treatments - Supine Position
• Viral Respiratory Tract Factors that impede normal Infection Pulmonary Toilet
Colonisation - Abdominal or thoracic surgery• Intensive Care Setting - Immobilisation• Use of Antimicrobial Agents• Contaminated hands• Contaminated Equipment

Early onset VAP is caused by Streptococcus pneumonia, H influenza, Moraxella catarrhalis and methicillin-sensitive Staphylococcus aureus (MSSA).
Late onset VAP is caused commonly by Pseudomonas aeruginosa, Acinetobacter, Enterobacter species and methicillin resistant staphylococcus aureus (MRSA).
VAP is frequently polymicrobial and gram negative bacilli are the predominant organism’s isolated.
Prevention of Ventilator-Associated Pneumonia
Gastric pH The use of sucralfate, an agent that does not increase gastric pH, may be
preferable to H2 receptor antagonists or proton pump inhibitors. Three studies found decreased mortality rates in patients treated with sucralfate rather than H2 receptor antagonists or proton pump inhibitors.
Positioning Positioning of the head of the bed at 30 degrees is the most cost-effective
intervention for prevention of VAP. This position results in decreased gastroesophageal reflux.
Subglottic Aspiration of Secretions Pooling of secretions above the endotracheal tube cuff may increase the
volume of bacteria that enter the airways. Removal of these secretions by continuous aspiration in the subglottic region requires the use of a specialized endotracheal tube with a second lumen that permits a suction catheter to exit proximal to the endotracheal tube cuff.
Aminoglycosides and quinolones are bactericidal in a concentration dependent fashion.
In addition these agents have a prolonged postantibiotic effect (PAE), allowing them to suppress bacterial growth even after their concentrations are below target level.
vancomycin and the beta-lactams (penicillins, cephalosporins, aztreonam) are also bactericidal but act in a time-dependent rather than in a concentration-dependent fashion, do not possess significant postantibiotic effect against gram negative bacilli,
Generally speaking, empirical therapy should be commenced once NP is suspected and altered as microbiologic data become available
Catheter-Related Bloodstream Infections
It is estimated that more than 5 million CVCs are inserted every year in the United States.
Unfortunately, more than 15% of patients have complications from these lines. Infectious complications are reported to occur in 5% to 26% of patients with
CVCs.
The mortality rate attributable to CRBSIs ranges from 12% to 25%,
Prevention of Central Venous Catheter Infections Antibiotic-Impregnated Central Venous Catheters
Examine the efficacy of antimicrobial-impregnated catheters in an effort to decrease the incidence.
CVCs coated with the antimicrobials chlorhexidine and silver sulfadiazine or impregnated with the antibiotics minocycline and rifampin are commercially available.
Chlorhexidine/sulfadiazine-coated catheters lowered the rate of bloodstream infection from 7.6 to 1.6 infections per 1000 catheter-days (P = .03).
The use of antimicrobial-impregnated catheters should be considered in all critically ill patients who require long-term (at least 3 days) indwelling central venous access.
Immunocompetent patients who will be catheterized for less than 3 or 4 days may not need these catheters because infection is rare during this period.
Sterile Technique Optimal sterile technique is the most cost-effective means of
reducing the incidence of central line colonization and CRBSI. Use of maximal sterile barrier precautions such as mask, cap,
sterile gown, sterile gloves, and a large sterile drape. Use of chlorhexidine solution for skin decontamination reduces the
risk of catheter colonization and is therefore preferred over the use of povidone-iodine solution.
Ultrasound Guidance With the development of portable, inexpensive ultrasound
machines, for reducing the complications associated with central venous cannulation .
Ultrasound guidance has been shown to reduce the number of complications, unsuccessful attempts, and time required for insertion of an internal jugular vein catheter,
Clinical trials assessing whether use of ultrasound can decrease the incidence of central venous line infections remain to be completed, but this technology can decrease the number of attempts required to locate the internal jugular vein and should be used routinely when available.
Duration The need for a CVC should be reassessed daily, and unnecessary catheters
should be removed because the probability of catheter-related infections increases with time.
The risk of infection with catheterization stays relatively low until about the fifth to seventh days and then increases.

Cleaning more Important than Disinfection and Sterilization
Cleaning Removes
contaminants, Dust, organic
matter,Disinfection Reduces number of
microbes
Sterilization is absolute, removes microbes and spores too.
To achieve Sterilization is Expensive, not sustainable, many times not needed.
An effective Disinfection reduces the infections drastically.
To Sterilization of ICU formaldehyde gas (bactericidal & sporicidal,viricidal) is widely employed as it is cheaper for sterilization of huge areas like operation theatres and ICU.
Formaldehyde kills the microbes by alkylating the amino acids and sulfydral group of proteins and purine bases.
In spite of the gas being hazardous continues to be used in several developing countreis
