1 - Systematic Approach Flashcards
4 Types of Respiratory Problems
- Upper Airway Obstruction
- Lower Airway Obstruction
- Lung Tissue Disease
- Disordered Control of Breathing
4 Types of Circulatory Problems
- Hypovolemic Shock
- Distributive Shock
- Cardiogenic Shock
- Obstructive Shock
ABCDE
Airway Breathing Circulation Disability Exposure
Signs of Maintainable Airway
Airway is obstructed but can be maintained by simple measures - head tilt-chin lift
Signs of not Maintainable Airway
Airway obstruction that cannot be maintained without advanced interventions - intubation
Signs of upper airway obstruction
- Increased inspiratory effort with retractions
- Abnormal inspiratory sounds (snoring or high pitched stridor)
- Resp effort but no airway/breath sounds
Ways to position a responsive child for optimal breathing
- Allow the child to assume a position
2. Elevate HOB
Ways to position an unresponsive child for optimal breathing
Turn child on side if you do not suspect cervical injury
Use a head tilt-chin or jaw thrust
Foreign Body? <1 year of age
5 Back slaps and 5 Chest thrusts
Foreign Body? >1 year
Give abdominal thrusts
Fast Respiratory rate possibly reasons
Sepsis Fever Pain Dehydration CHD Anemia
What is an ominous clinical sign of impending arrest in infant or children
Bradypnea or irregular RR in acutely ill children
Three types of apnea
- Central Apnea
- Obstructive
- Mixed Apnea
Central Apnea is…
No respiratory effort
Central nervous system is not send signals regularly or at all
Obstructive Apnea is…
Inspiratory effort without airflow
Obstruction is in the way
Mixed Apnea is…
Periods of obstructive and central apnea
When do agonal gasps present in a child?
Very late deterioration
Increased respiratory rate is from
conditions that increase resistance to airflow
Examples of conditions that increase resistance to airlfow
- Bronchitis
- Asthma
- Anything that causes stiff lungs and difficult to inflate
3 objective signs of a child trying to compensate and increase respers
- Nasal Flaring
- Retractions
- Head bobbing/seesaw respirations
Retractions
inward movement of the chest wall/tissues/sternum during inspiration. Trying to move air into the lungs
Retractions w/ stridor or an inspiratory snoring
Upper Airway Obstruction
Retractions by expiratory wheezing
Lower Airway Obstruction
obstruction during both ins and exp
Retractions WITH
grunting or labored respirations
Lung Tissue Disease - Grunting to keep the alveoli open
Head Bobbing is using what muscles
neck muscles
Seesaw respirations are seen in children w/
neuromuscular disease
Tidal volume measurement
5 to 7ml/kg
Minute Ventilation Equation
RR X Tidal Volume
Stridor/Reason
High pitched - Upper Airway Obstruction
Snoring reason
Soft tissue swelling or dec LOC
Grunting/Reason
Low pitched sound during expiration
Exhale against a partially closed glottis
Lung Tissue Disease
Pain from abd pathology
Gurgling/Reason
Bubbling sound during insp and exp
Upper airway obstruction due to secretions, vomit, blood
Wheezing/Reason
Whistling - mostly during expiration
Usually intrathoracic
Isolated inspiratory wheezing suggests
a foreign body / upper ariway/trachea
Crackles mainly during exp or insp?
Inspiratory
Fluid filled alveoli opening causing crackles
Wet crackles
Fluid filled alveoli
Dry crackles
Atelectasis or interstitial lung disease (Scaring of the lung tissue)
Cause of RUBBING
Infant/child develops “Barking”
Upper Airway Obstruction
O2 saturation does not indiacte
02 delivery
Profoundly anemic?
Saturation could be 100% but 02 content in the blood and 02 delivery may be low
What to be careful with CO posioning
Falsely high 02 saturation bc it counts the carboxyhemoglobin as fully saturated hemoglobin
What is methemoglobin
When the iron in the body is in the ferrite state not the normal ferrous
Cannot bind oxygen meaning - no O2 to tissues
Methemoglobin clinical signs
if methemoglobin concentrations are above 5% - the pulse ox will read approximately 85% regardless of the degree of methemoglobinemia
Some drugs that can cause methemoglobin
Nitrates, Topical anesthetics (benzoincaine), local anesthesia
Pulsus Paradoxus
Cardiac Tamponade
Dec pulse strength (and BP) during inspiration
More than 10mmhg decrease systolically due to the preload causing the septum wall to curve in towards the left ventricle
What is and Causes of cardiac tamponade
What is: Excessive accumulation of fluid within the pericardial sac
Cancer, Kidney failure
TB, pericarditis
Beck’s Triad
- Low BP
- Increased JVD
- Muffled heart sounds
Hypotension w/ hemorrhage is how much of a loss of circulation blood volume
20-25%
UO for infants and young children
1.5 to 2ml/kg per hour
UO for older children and adolescents
1 ml/kg per hour
Disability is evaluating
neurologic function
Standard evaulation
- APVU (alert, responsive to voice, responsive t pain, unresponsive)
- GCS
- Pupil reaction
- BS
Eye Opening GCS

Pinpoint puppils

Brief head to toe
Infants compensate for hypercarbia through
renal retention of bicarb
Arterial Lactate means…
Metabolic acidosis - associated w/ tissue hypoxia
Anaerobic Metabolism
What is lactic acid
When there is not enough oxygen to break down glucose/glycogen and the body instead breaks down carbohydrates for energy
What lactic acid level is abnormal
> 2
