Used at the beginning of the initial assessment 1. A Alert. If the pt is alert he or she will be able to maintain his or her airway once it is clear. 2. V responds to verbal stimuli responds to pain. If the patient needs verbal stimulation to respond, an airway adjunct may be needed to keep the tongue from obstructing the airway. 3. P responds to pain. If the pt. responds only to pain, he or she may not be able to maintain his or her airway adjunct may need to be placed while further assessment is made to determine the need for intubation. 4.

Preparation 2. Preoxygenation 3. Pretreatment 4. Paralysis and Induction 5. Protecting and positioning - v 6. Placement of proof - secure the tube 7. Post intubation - secure ETT Tube, get X-ray for placement - ANSWER Steps of Rapid Sequence Intubation from hemorrhage is leading cause. Hypovolemia is caused by decrease in the amount of circulating volume. Goal is to replace volume. - ANSWER Hypovolemic Shock results from hypo perfusion to the tissue due to an obstruction in either vasculature or heart. Goal is to relieve obstruction and improve perfusion. Ex: tension pneumo or cardiac tamponade are two classic examples that may result from trauma. - ANSWER Obstructive Shock Results from pump failure in the presence of adequate intravascular volume. There is a lack of cardiac output and end organ perfusion secondary to a decrease in myocardial contractility and/or valvular insufficiency. Ex: MI's or dysrhythmia are common causes - ANSWER Cariogenic Shock occurs as a result of maldistribution of an adequate circulating blood volume with the loss of vascular tone or increased permeability. Ex: Anaphylactic - release of antihistamines Septic Shock - systemic release of bacterial endotoxins, resulting in increased vascular permeability and vasodilation. Neurogenic shock - spinal cord injury results of loss in sympathetic nervous system control of vascular tone. Goal: Volume replacement and vasoconstriction - ANSWER Distributive Shock A breath every 5 to 6 seconds: 10-12 ventilations per minute - ANSWER Bag mask ventilation Stroke Volume X HR - ANSWER Cardiac Output = .. activation: .... are found in the carotid sinus and along the aortic arch, are sensitive to the degree of stretch in the arterial wall. When the receptors sense a decrease in stretch, they stimulate the sympathetic nervous system to release Epi, norepi, causing stimulation of cardiac activity and constriction of blood vessels, which causes a rise in heart rate and diastolic blood pressure - ANSWER Baroreceptors: activation: consist of carotid and aortic bodies. ... detect changes in blood oxygen and Co2 and pH. When Co2 rises or oxygen level of pH falls these receptors are activated and information is relayed to the CNS and the cardiorespiratory centers in the medulla , which increases respiratory rage and depth and BP - ANSWER Chemoreceptors: 50 to 150 - ANSWER MAP Range the decrease coagulopathy .. you will you bleed more - ANSWER The colder you are the more acidic you are.. in massive transfusion protocol... responsible for dissolving clots - ANSWER TXA stabilized vital signs, improved mental status, improved urine output - ANSWER What are indicators of increased perfusion? - ANSWER Prehospital shock index pg. 85 Flail chest - ANSWER Paradoxical chest wall movement can be caused by blunt trauma. air escapes from injured lung to pleural space and negative intrapleural pressure is lost causing partial or collapsed lung - ANSWER Simple Pneumothorax 1. Dyspnea 2. Tachycardia 3. Decreased or absent breath sounds on the injured side 4. CP - ANSWER Simple Pneumo assessment: Tx is based on size, presence of sx, and stability. For those are aysmpomatic and stable. Observation with or without oxygen. Larger pneumo who are unstable or likely to deteriorate a chest tube is placed. - ANSWER Simple pneumo interventions: can result from penetrating wound through chest wall causing air to be trapped in to the intrapleural place. Might hear "sucking" Tx: nonporous dressing tapes on 3 sided, then Chest tube and would closure surgical repair. - ANSWER Open Pneumo: Air cannot escape intrapleural space.. can begin to compress heart. pt will have sever resp distress, hypotension, JVD. - ANSWER Tension pneumo A 14 gauge needle that is inserted into the 2nd intercostal space in the midclavicular line on the affected side over the top of the rib to avoid neuromuscular bundle that runs under the rib. Prepare for chest tube placement. - ANSWER Tension pneumo intervention Caused by blood in the intrapleural space/ May also occur from lac to live or spleen combined with injury to the diaphragm. Ensure two large bore IVS are placed. Prepare for thoracentesis and chest tube insertion. If open thoracotomy is done chest tube is deferred. - ANSWER Hemothorax: 1. Hypotension 2. JVD 3. Muffled heart sounds - ANSWER Becks Triad: Needle pericardiocentesis, but it is a temp solution. Requires surgical evaluation. (Ultrasound guided) - ANSWER Cardiac Tamponade Intervention: Aortic Dissection - ANSWER Unequal extremity pulse strength possibility of.. 1. pain - hallmark sign, early sign 2. pressure - early sign 3. pallor, pules, paresthesia, paralysis - late sign - ANSWER Six P's of compartment syndrome: Pediatric Assessment Triangle 1. General appearance - muscle tone, interactiveness, consoloability, poor or gaze, speech or cry 2. Work of breathing - inadequate or excessive, accessory muscle use, retractions, tripod position, abnormal upper airway sounds 3.
