CHEST TUBE 101 Critical Care Boot Camp Class 1
![Page 3: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/3.jpg)
NORMAL BREATHING
Inhalation - the diaphragm contracts, the ribs move up and out, the sternum moves out, and the lungs expand
Exhalation - the diaphragm relaxes, the ribs move down and in, the sternum returns to normal position, and the lung volume decreases
This process occurs automatically, as regulated by the central nervous system via the respiratory centers in the pons and medulla
Negative intra-pleural pressure keeps the lungs against the chest wall. Loss or disruption of this pressure leads to lung collapse.

A & P BASICS
Visceral/Pulmonary pleura - a thin membrane covering the lungs
Parietal pleura - a thin membrane lining the rib cage
Pleural space - the space between the parietal and visceral pleura
Pleural fluid - a thin layer of lubricating fluid in the pleural space that allows the two membranes to slide across one another when the lungs expand and contract

CARE AND ASSESSMENT OF PATIENT WITH A CHEST TUBE
Physical assessment of the patient
Special consideration given to the patient’s respiratory status
Check the chest tube site/dressing for leakage
Reinforce the dressing, if necessary, to ensure the tube’s safety
Starting from the patient, work your way down to the collection chamber, checking for kinks in the tubing
Make sure the connections are secure, paying close attention to the connection between the chest tube/pigtail and the drainage tubing
Assess for any blood or tissue clots in the chest tube, as these may prevent adequate drainage
![Page 25: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/25.jpg)
ASSESSMENT
Check the drainage systemCollection chamber
Note the date/time of the last recorded volume
Drainage rate > 10 mL/kg/hour should be reported to the physician
Water seal chamber
Disconnect system from suction and assess for water level fluctuation with respirations
Note the presence of bubbling, as this will indicate an air leak
Suction control chamber
The water in this chamber should bubble gently when suction is applied. If the bubbling is vigorous, the amount of suction needs to be decreased
![Page 26: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/26.jpg)
IMPORTANT POINTS!
IF THE CHEST TUBE FALLS OUT: Quickly cover and seal the insertion site with a sterile petroleum gauze dressing to prevent air from entering into the pleural cavity. Notify the physician immediately!!!
SAFETY SACK: there should ALWAYS be an emergency chest tube kit at the bedside. The kit should contain:
sterile petroleum gauze dressing
2 x 2 or 4 x 4 gauze
transparent dressing
hemostats
a small bottle of sterile water
![Page 27: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/27.jpg)
REMOVAL OF A CHEST TUBE
An order must be obtained and the chest tube is always removed by a physician!
Administer pain medication prior to chest tube removal
Obtain a suture removal kit
Have your emergency kit supplies open and ready
The MD/NP/PA will remove the chest tube:
Ask the patient to take a deep breath or wait for the infant/small child to inspire
The tube is removed during inspiration
Sterile dressing is applied: Petroleum gauze to seal the insertion site
2 x 2 or 4 x 4 covering the petroleum gauze
Cover with a transparent dressing
![Page 28: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/28.jpg)
INTERVENTIONS POST CHEST TUBE REMOVAL
Incentive spirometry, coughing, and deep breathing exercises are very important after chest tube removal
These activities should be reinforced with all patients who are able to participate
![Page 29: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/29.jpg)
CARING FOR THE CHILD IN SHOCK Critical Care Boot camp Class 1
![Page 30: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/30.jpg)
WHAT IS SHOCK?
oA sustained, progressive circulatory dysfunction resulting in inadequate cardiac output and delivery of oxygen to meet metabolic demand, along with compromised tissue utilization of available oxygen
HUH?!
What does that mean?
![Page 31: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/31.jpg)
DEFINITION IN PLAIN ENGLISH
oA drop in cardiac output = decreased blood flow to the tissues
oDecreased blood flow = not enough oxygen reaching the tissues (decreased perfusion)
oLack of perfusion leads to multi-system failure
oIf not treated, the body’s response to inadequate perfusion is death
![Page 32: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/32.jpg)
PERFUSION
oDependent Variables:
oBlood Volume
oCardiac Pump
oVascular Tone
oAdequate Oxygenatio n
oCellular Function
oWhen one variable fails, the other must compensate
![Page 33: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/33.jpg)
TYPES OF SHOCK
o Cardiogenic
o Obstructive
o Hypovolemic
o Distributive
o Anaphylactic
o Neurogenic
o Septic
![Page 34: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/34.jpg)
CARDIOGENIC SHOCK
o The result of myocardial dysfunction
o Structural: congenital heart defects
o Non-structural: inflammatory heart disease,
metabolic/electrolyte imbalances, drug toxicities, cardiac
tamponade, dysrhythmias
o The heart is unable to pump enough blood out to meet the body’s
needs, resulting in pulmonary congestion and inadequate tissue
perfusion
o TREATMENT: increase cardiac output by restoring myocardial
function
![Page 35: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/35.jpg)
HYPOVOLEMIC SHOCK
oThe most common type of shock in infants and children
oResults from inadequate intravascular volume
oCaused by blood loss, dehydration, fluid shifts related to capillary leak
oLack of volume = decreased blood flow to tissues and organs
oTREATMENT: fluid resuscitation and treatment of the underlying cause
![Page 36: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/36.jpg)
DISTRIBUTIVE SHOCK
oDecreased blood flow due to decreased systemic vascular resistance
oCommon causes
oEarly septic shock, anaphylaxis, toxic ingestions, spinal or epidural anesthesia, spinal cord injuries
oAssessment details
oFlushed skin, warm extremities, bounding pulses, tachycardia (except SCI), wide pulse pressure, brisk capillary refill
oTREATMENT: reversal of underlying etiology, rapid volume expansion, vasoactive medications
![Page 37: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/37.jpg)
ANAPHYLACTIC SHOCK
oInitiated by an overwhelming response to an allergen
oComplete vasodilation and increased capillary permiability
oThird-spacing results in intravascular hypovolemia
oTREATMENT: removal of allergen, when possible, and symptom management (antihistamines, subcutaneous epinephrine, and steroids)
![Page 38: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/38.jpg)
NEUROGENIC SHOCK
oOccurs following insult to the spinal cord or nervous system (spinal cord injury, spinal anesthesia, nervous system injury)
oCauses loss of sympathetic tone, which leads to arterial and venous vasodilation
oTREATMENT: stabilize spinal cord injury and minimize additional trauma, elevate lower extremities and apply anti-embolic stockings and/or compression devices to encourage venous return
![Page 39: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/39.jpg)
SEPTIC SHOCK
oRelated to a severe infection, usually caused by gram-negative bacteremia
o“Sepsis” = the body’s systemic response to infection
oDefinition: sepsis with hypotension, despite adequate fluid resuscitation, along with perfusion abnormalities
oTREATMENT: treat the infection and support circulation/perfusion. Antibiotics must be given as soon as possible after blood cultures are obtained
![Page 40: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/40.jpg)
SEPSIS
oThe body’s systemic response to infection
oA systemic inflammatory response syndrome (SIRS) that alters capillary permiability, impairing vasoregulation
oInflammatory cells and mediators cause endothelial injury, tissue hypoxia, and microthrombi formation
oLeads to organ dysfunction/failure, and can cause death
![Page 41: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/41.jpg)
LEVELS OF SEPSIS
o Sepsis – the presence of SIRS accompanied by an infection
o Severe Sepsis – sepsis plus end-organ dysfunction resulting from lack of
perfusion
o Septic Shock – severe sepsis with persistent hypotension and decreased
tissue perfusion, despite fluid resuscitation
o Multiple Organ Dysfunction Syndrome (MODS) – Presence of altered
organ function in an acutely ill patient, such that homeostasis cannot be
maintained without interventions
![Page 42: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/42.jpg)
CLASSIFICATION OF SHOCK
• Compensated– Blood pressure remains NORMAL
– Compensatory mechanisms are able to redistribute blood flow or maintain vascular tone
• Decompensated– Blood pressure is LOW
– Compensatory mechanisms are no longer able to support blood flow or vascular tone
• Irreversible– Decompensated shock where cardio-pulmonary arrest is imminent
![Page 43: CRITICAL CARE BOOT CAMP CLASS #1 - Nicklaus Children's ...](https://reader031.fdocuments.net/reader031/viewer/2022013005/61cd6722ecb073210708d893/html5/thumbnails/43.jpg)
