Such patients may be unstable, have complex needs, and require intensive and Characteristics of a Critical Care Nurse vigilant nursing care. Attributes of critical care nurse = quality and behavior - Examples of Critical ill clients: Critical care nurses need to ACT Who needs immediate surgery 1) Advocate – a person who works on another person’s Post surgical behalf (protect his/her rights, assist with family decisions, With Comorbidities negotiate with other members of the healthcare team, Diagnosed with diseases that affects multiple parts of keeping patient and family informed) the body 2) Critical Thinker – a person with a complex mixture of Emergency conditions knowledge, intuition, logic, common sense, and experience.

Many times, team members perform assessment and actions in ACLS simultaneously. - An important component of this survey is the differential diagnosis, where identification and treatment of the underlying causes may be critical to patient outcome. - REMEMBER! For unconscious patients, healthcare providers should conduct the BLS Survey followed by ACLS Survey. For conscious patients, providers should conduct ACLS Survey first.

J.A.K.E 6 of 16 CRITICAL CARE NURSING LECTURE: BSN 4TH YEAR 1ST SEMESTER PRELIM 2023 Step 2 – Gather Evidence To describe if clinical practice is streamlined when questions are asked 1) Internal Evidence - Direct from client or institutions 2) External Evidence - Scientific literatures; research database - Kapag maghahanap ng research = Meta-analysis papers 3) Database Step 3 – Assess the Evidence - Once articles are selected for review, these must be rapidly appraised to determine those most relevant, valid, reliable, and applicable to the clinical question. (Guide: Are the results of the study valid? What are the results and are they important? Will the results help me care for my patients?) - Iassess kung quality sya or hindi, kung applicable ba sya sa setting mo 1) Internal Evidence – Does this study investigate a population similar to my client? 2) External Evidence – Is your client demonstrating a response to the intervention? Step 4 – Make your Clinical Decision - Synthesize the studies to determine if they come to similar conclusions, thus supporting an EBP decision or change - Research evidence alone is not sufficient to justify a change in practice. Clinical expertise, based on patient assessments, laboratory data, and data from outcomes management programs, as well as patients' preferences and values are important components of EBP 1) Define – Your clinical question 2) Extrapolate – Applicable information from external evidence 3) Consider – Clinical expertise 4) Incorporate – Needs and perspectives of clients 5) Develop – Assessment & treatment plan 6) Evaluate – Your clinical decision Forest plot - An essential tool to summarize information on previously published study findings. - Research figure - Invented by Richard Peto (Statistician and Epidemiologist, Pag nagcross ng line ung diamond = parehas lng, walang University of Oxford) difference ang intervention Pag hindi sya nag cross ng line = meron syang pagkakaiba Salient Points to consider in the use of EBN Practice: Promotes use of EBP among advanced practice nurses and direct care nurses Identifies a network of stakeholders who are supportive of the EBP project Cognitive behavioral theory underpinnings Emphasis on healthcare organizational readiness and identification of facilities and barriers Encompasses research, patient values, and clinical expertise as evidence.

For example: (Ang flow ng electricity ay mayroong direction. SA node---- - Normal rate is 60-100 for adults. Rate of less than 60bpm Atrioventricular Node----- Purkinje Fibers. Therefore, kapag is bradycardia, while more than 100bmp is tachycardia. nagplace ng leads sa chest ng client at nagfunction ang heart ay mayroong connection) STEP 2: Determine the Rhythm - Check the P-P interval (atrial) of R-R interval (ventricular). Rhythm may be regular or irregular. STEP 3: Determine Presence of P-wave - This can be done by locating an evident p-wave before the QRS complex; and if each P-wave is related to a QRS with 1:1 conduction. STEP 4: Check PR Interval (Ang waves ay parang spaghetti, mayroong pataas at pababa. - Count the number of small squares between the start of Yung pataas ay tinatawag na positive deflection meaning yung the P- wave and the start of the QRS complex; then pinakalocation ng electrodes ay papunta roon sa positive pole. multiply the number of squares by 0.04 second; normal ‘Yung negative deflection naman ay pababa wherein ang duration is 0.12 to 0.20 second. direction naman nito ay papuntang negative pole.) STEP 5: Check QRS Complex - Check is QRS complex is evident and similar in size and shape. Normal duration is 0.06 to 0.10 second STEP 6: Determine Presence of T-wave - This can be done by locating an evident T-wave after the QRS complex; and if each t-wave has normal shape and size. STEP 7: Check QT Interval - Count the number of small squares between the beginning of the QRS complex and the end of the T wave, where the T wave returns to the baseline; normal duration is 0.36 to 0.44 second STEP 8: Evaluate other components - Check for rhythm abnormalities (for example, flutter, fibrillation, heart block, escape rhythm, or other arrhythmias). J.A.K.E 12 of 16 CRITICAL CARE NURSING LECTURE: BSN 4TH YEAR 1ST SEMESTER PRELIM 2023 Sinus Rhythm Normal Sinus Rhythm - refers to any cardiac rhythm where the sinoatrial node is - It is imperative for critical care nurses to recognize the generating impulses within the cardiac muscle. The normal sinus rhythm to ascertain deviations and presence of sinus rhythm is necessary, but not sufficient, abnormalities. for normal electrical activity within the heart. Normal Sinus Rhythm (NSR) - If there is sinus rhythm and the heart rate is greater than Characteristics Description 100, then “sinus tachycardia” is present. If the there is Rate 60-100 bpm sinus rhythm and the heart rate is less than 60, then “sinus Rhythm regular bradycardia” is present. If there are no P waves present or P-wave precede QRS, consistent shape the P wave morphology is not normal, then the exact PR Interval 0.12 to 0.20 second rhythm must be determined. QRS Complex 0.04 to 0.10 second Normal Sinus Rhythm Conduction normal flow Rhythms Originating in the Sinus Node Sinus Bradycardia Sinus Tachycardia Sinus Bradycardia - can be normal findings in athletes Cardiac Arrhythmia during sleep; may be a response to vagal simulation and - a problem with the rate or rhythm of the heartbeat. During certain medications (digitalis, beta-blockers, calcium an arrhythmia, the heart can beat too fast, too slow, or with channel blockers); seen in patients with increased ICP, an irregular rhythm. uremia, myxedema and obstructive jaundice. - Arrhythmias are any cardiac rhythm that is not normal sinus rhythm. It may result from altered impulse formation or conduction. Arrhythmias are named by the place where they originate and by their rate. The typologies of arrhythmias are as follows: (a) rhythms originating in the sinus node, (b) rhythms originating in the atria, (c) rhythms originating in the ventricle, and (e) AV blocks. Sinus Tachycardia - a normal response to exercise and emotion; and can be caused by some medications (e.g. ephinephrine, dopamine, caffein) J.A.K.E 13 of 16 CRITICAL CARE NURSING LECTURE: BSN 4TH YEAR 1ST SEMESTER PRELIM 2023 Sinus Arrhythmia - occurs when sinus node discharges Rhythms Originating in the Ventricles irregularly, and is a normal phenomenon during respiration; [NOTE: ventricular arrhythmias are considered to be more may be caused by digitalis toxicity. dangerous than other arrhythmias due to their potential to decrease cardiac output] Sinus Arrest - occurs when impulses from the sinus node are not formed as expected (p-wave absent at some point); also known as sinus pause; causes include vagal simulation and drugs (digitalis, beta-blockers, calcium channel blockers) Ventricular Asystole - absence of any ventricular rhythm. Rhythms Originating in the Atria Ventricular Fibrillation - rapid, ineffective quivering of the ventricles; no cardiac output or palpable pulse (fatal without immediate treatment) Supraventricular Tachycardia - rapid rhythm of the heart that begins in the upper chambers. Atrial Flutter - caused by fixed re-entry circuit in the right atrium on patients with health concerns (e.g. rheumatic heart disease, atherosclerotic heart disease, heart failure, myocardial infraction) Ventricular Tachycardia - rapid ventricular rhythm; commonly caused by coronary artery diseases. Atrial Fibrillation - an extremely rapid and disorganised pattern of depolarisation; most commonly seen in adults AV BLOCKS post cardiac surgery and with conditions such as rheumatic heart disease, pulmonary disease , MI, and First Degree AV Block - prolonged AV conduction to the congenital heart disease ventricles; due to coronary artery disease, rheumatic heart disease and administration of some drugs (e.g. digitalis, beta- blockers or calcium channel blockers).

They are interchanging their roles every now and then. (Kasi nakakapagod mag compress all the time, palitan sila) 3) Monitor Defibrillator - Brings and operates the AED monitor/defibrillator and acts as the CPR Coach if designated. - If the monitor is present, places it in position where it can be seen by the team leader (and most of the team) - Partner of compressor - He or she is the one who checks the cardiac monitor and provides shock if necessary.
