This includes checking the fingers for clubbing or splinter haemorrhages. The first sound you hear is S1 and is caused by the closure of the atrioventricular valves (AV) TRICUSPID AND MITRAL VALVES. S2 is normal. S1 and S2 are heard and are of normal intensity. Support + education for early career nurse practitioners. From the general practice to the ICU, listening to lung sounds can tell you a great deal about a patient and their relative health. This article is a compilation of guides on assessing lung, heart and bowel sounds. Sounds like: Lub du bub S1S3S2 cadence similar to "Kentucky" Clinical Significance: Results from increased atrial pressure leading to increased flow rates, as seen in congestive heart failure, which is the most common cause of a S3. Here’s a quick guide to documenting an exam of the heart. Describe carefully the sound head that is abnormal.  Is it a “rubbing sound” or a “clicking sound” a “swooshing” or other?  Chart the sound just as you heard it. Following is a guide to auscultation of sounds of the heart.  It is only a guide, and should be used with existing guidelines at your facility.  The methods of charting are different at each hospital, so are responsibility levels for each type of nurse.  Always use terms which are acceptable at your facility.  If a heart sound or murmur is accompanied by adverse clinical symptoms, results should be reported. A minimally split first heart sound is a normal variation of the first heart sound. Heart sounds are generated by valves that control bloodflow in and out of the heart’s chambers. Specializes in School Nursing. That is not to diminish the importance or difficulty of acquiring the necessary skills. Factors that affect the sympathetic nervous system are: anxiety, fear, fever, extreme physical exercise, other.  These conditions will generally cause an increase in the sympathetic stimulation of the SA node and subsequently, tachycardia. An aortic ejection click follows the first heart sound by 75 milliseconds.

PMI is not visible and is palpated in the 5th intercostal space at the midclavicular line. These sounds are produced when the pericardium becomes inflamed. With your stethoscope, identify the first and second heart sounds (S1 and S2). Timing-describe where the sound is heard in the cardiac cycle. Any ideas for describing something that sounds normal in other words?? S1 occurs with the downstroke of the R wave on the EKG.  It also occurs simultaneously with the carotid impulse upstroke. S2 is caused by the closure of the aortic and pulmonic valves. The normal heart beat is also referred to as sinus rhythm, or being initiated in the sinoatrial nods.  Very specifically, if the rate is normal and the heart beat is a sinus rhythm, it is called “normal sinus rhythm.”  Using this terminology, it would be easy to see why a rapid but otherwise normal (sinus) rhythm, is called sinus tachycardia.  Conversely, a slow, but otherwise normal (sinus) rhythm is called sinus Bradycardia.  Both of these arrhythmias are not normal, but they are usually not severe or life-threatening.  The nurse might easily understand that sinus tachycardia could be caused as a normal reaction to anxiety.  In fact, just being sick and in the hospital might produce anxiety and also sinus tachycardia.  The nurse would need to assess the patient very carefully if a rapid heart rate is present; especially if there are no adverse clinical signs or symptoms present.  Of course, an EKG tracing and interpretation would be necessary to absolutely confirm that only sinus tachycardia is present, and that there is now immediate danger to the patient.Â. 3. Normal Respirations physiological splitting of S2. For instance, the absence of bowel sounds after a surgery can indicate an ileus before the patient starts vomiting or complaining of abdominal pain. The murmur of aortic insufficiency is caused by the backward flow of blood from the aorta into the left ventricle across an aortic valve that is incompetent.  This backward pressure exerted by the blood in the aorta is the greatest, just after the closure of the aortic valve and progressively fall thereafter thought diastole. Cap refill : Resp: rate, rhythm, depth, effort Accessory muscle use Chest expansion Breath sounds: Rate 20, even, unlabored respirations. Decrescendo/Crescendo begins loudly, becomes softer, and then becomes loud again. The sound produced is described as regurgitation.  The murmur usually beings immediately after S2 and can progress throughout the entire diastole.  This murmur is best heard at the base of the heart and will often radiate to the apex. S2        Listen for S2 split in the pulmonic and secondary aortic area.  Ask the patient to breathe deeply through the nose to accentuate the split. Other factors affect closure.  Exercise, fever, anemia, and other factors and affect heart rate and force of the closure of the valves. Assessing heart rate: You can calculate the heart rate in a number of ways, including measuring for 60 seconds, measuring for 30 seconds and multiplying by 2 or measuring for 15 seconds and multiplying by 4. Record vital signs, TPR and blood pressure, note any abnormalities. Heart murmurs are heart sounds produced when blood is pumped across a heart valve and creates a sound loud enough to be heard with a stethoscope.

Only then is it time to move to the chest and even then it is still not y… No murmurs, gallops, or rubs are auscultated. There are two periods of this rapid ventricular filling in the cardiac cycle.  These are: early diastole, shortly after the opening of the atriventricular valves; and immediately prior to the onset of systole just s the atria contract.  This explains why there are two murmurs heart in mitrial stenosis.  The first is an early to middiastolic murmur and a presystolic murmur.  There is also another distinct sound heard with the condition of mitral stenosis.  This sound is referred to as the opening snap of mitral stenosis.  Normally, this opening of the mitral valve is silent.  In the presence of mitral stenosis, there is a sharp, high-pitched click that can be ausculated.  The click is best heard between the apex and the lower left sterna border. Listening to the heart sounds through a stethoscope (auscultation) is one of the first steps a physician takes in evaluating a patient’s medical condition. Sounds referred to as “rubs” occur when the visceral and parietal layers of the pericardium rub together. If you’re a nurse practitioner who could use a documentation brush up, check out this quick guide to documenting a cardiovascular exam. at the tricuspid and mitral area (apex) S1 is often, but not always louder than S2. Your email address will not be published. Holosystolic Stays the same intensity through systole and diastole, also called pansystolic murmur. A heart murmur is a very general term used to describe any one of the verity of abnormal sounds heard in the heart due to turbulent or rapid blood flow through the heart, great blood vessels, and/or heart valves (whether the heart valves are normal or are diseased).  Most nurses associate murmurs with an abnormal heart valve.  However, there are a variety of other conditions that can cause murmurs.  Murmurs can also be caused by the forward flow of blood across a constricted or otherwise irregular valve, or into a dilated heart chamber or dilated vessel.  They can also be caused by the backward flow of blood through an incompetent valve or a septal defect murmurs are usually described as a “rushing” or “swooshing” sound.  Murmurs are usually related to defect in valves or ventricular septal defect, or atrial septal defect. Abnormal heart sounds are called heart murmurs. Patient’s home address If a patient label containing at least 3 identifiers is available then this can be used instead of writing out … The bell of the stethoscope may be used for low frequency sounds (they are better amplified by the bell). S2 is single. So, for our purposes, we’ll break the exam and documentation of the chest down into its components. This murmur was recorded at the point of its maximal intensity over the mitral valve area (left apex). The loudness of the sound is also affected by the pressure of the blood.  It is this pressure that “slams” the valves shut and generates the sound.  If you recal that the interval between S1and S2 corresponds to the systolic phase, then a murmer that is heard between S1 and S2 wuld be called a systolic murmur.  Then a diastolic murmur would be called a murmer heard between S2 and S1, which corresponds to the diastolic phase of the cardiac cycle. Sign Up . Heart block varying intensity of S1 and S2 due to incomplete emptying of the atria, leaflets may be partially open at some times, completely open at others.Â. S1:    Supine or lying with upper body slightly elevated. Determine the regularity of rhythm; regular or irregular? at the aortic and pulmonic areas (base). Loudness, of course, is also affected.  Note the following changes due to disease: These are some disease conditions and the resulting change in the heart sounds.  The term murmur refers generally to any “extra” or unusual heart sounds.  Most nurses will not be expected of fully diagnose all murmurs and/or abnormal heart sounds.  However, the nurse should be able to recognize whether or not the two normal sounds are present, and if they are not, what sounds that are present, should be described carefully. Crescendo begins softly and becomes louder. SA node – variation of the rate of discharge of the node. The S3 creates and extra heart sound that can be rapid and very distinctive. Auscultation. There is a third heart sound gallop in diastole. Remember these areas do not correspond to the location of heart valves, but the areas where the cardiac sounds are best heard. Auscultation for heart sounds is mainly done in 4 areas, namely Mitral, Tricuspid, Aortic & Pulmonic. Systolic Murmurs: Mitral Regurgitation. S1 is considered the lub of 'LUB-dub.' Lung Sounds Made Easy. Auscultating the heart allows the nurse to assess the heart’s rhythm, rate, and sound of valve closure. For every new sheet of paper your first task should always be documenting at least three key identifiersfor a patient: 1. Auscultate left lateral, sitting, leaning forward, exhaling. An arrhythmia is described as an abnormal heartbeat.  An arrhythmia might be caused by one or more of several different factors: The “average” person’s heart rate is usually 70 – 100 beats per minute (BPM).  However, we all know that some persons may have a normal heart rate that is slightly higher or lower then these normal ranges.  Of course metabolism, exercise, and other factors will affect a person’s normal heart rate.  A rapid heart rate is called tachycardia, and a slower than normal rate is called Bradycardia. Heart sounds (S1, S2, S3, S4, murmurs) for nursing assessment examination. Unlock lessons, quizzes and more. For example, an early systolic murmur would be “timed” as occurring early in the phase of systole; and so on for all the phases.  Another term called holosystolic (also called pansystolic), is used to describe a murmur heard throughout the entire systolic phase (S1 to S2).  Similarly, holodiastolic will be used to refer to the murmur heard throughout the entire diastolic phase (S2 to S1). The S3 creates an extra heart sound that can be rapid and very distinctive. Client reports recent tachycardia when moving from bed to restroom post op. S1        S1 split best heard at lower left sterna border. Grade II           Medium Soft No extra heart sounds heard. Even though they’re little and hard to hear sometimes, they’re kind of a big deal. Learn more about ThriveAP, the program designed to boost primary care clinical knowledge. Grade V          Louder Systole is silent. Heart rate. The second sound you hear is S2 and is caused by the closure of the semilunar valves (SL) AORTIC AND PULMONIC VALVES. The heart murmur associated with mitral stenosis is caused by the flow of blood across the constricted mitral valve during the period of rapid ventricular filing. The timing of the murmur above is very difficult to assess in some patients.  In other patients, the timing will be very easy to assess. While learning to recognize heart sounds, try the inching technique. Description: Low frequency sound in early diastole, 120 to 180 ms after S2. An important factor is that the nurse has experience in listening to a variety of “normal” variation of normal heart sounds.  You must first listen to many different normal heart sounds.  Once you have some experience at differentiating normal S1 and S2 sounds, then you will be able to identify abnormal sounds, and to determine the timing of those abnormal sounds. If you’re learning to identify normal and abnormal pediatric heart sounds, keep this in mind: Actually auscultating pediatric patients is a better way to learn than listening to recordings. You are responsible for performing an appropriate physical exam and documenting your findings on each patient you interact with. When assessing a patient’s heart rate, you must consider that the heart rate is also controlled by the sympathetic and parasympathetic nervous systems.  The sympathetic nervous innervations increases the rate at which the SA node fires.  The parasympathetic nervous innervation decreases the rate of firing and subsequently the heart rate and produce a normal heart rate. The third heart sound S3 was discussed earlier as being normal in some adults an in children.  In the case of a pathological S3, it may be noted with ether vent of damage to the myocardium.  This heart sound, when ausculated, sounds like the gallop of a horse.  Indeed, it is described as a gallop. Some others use a scale of only I, II, III; so be aware of the scale that is generally used at your facility and apply the same principles to it.Â, Grade I            Soft This heart sound, when auscultated, sounds like the gallop of a horse. Holodiastolic  The same intensity throughout diastole; pandiastolic murmur. Objectives: Although congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and asthma patients typically present with abnormal auscultatory findings on lung examination, respiratory sounds are not normally subjected to rigorous analysis. When ausculatining murmurs, the nurse should record the timing, characteristics, location, and radiation of the murmur.  Characteristics include: loudness, intensity, pitch, and quality of the murmur.  These assessment factors are discussed in more detail later in the course. Lungs … On occasion the first heart sound can be made up of two separate sounds separated by a very small interval (20-30 milliseconds). The loudness and intensity of heart sounds are important when you are listening.  S1 and S2 are heard at different levels of loudness, depending upon where you listen on the chest.  The loudness of S1 is mainly determined by the position of the heart valves when ventricles contract.  If valve leaflets are wide open at the time of contraction, the sound is very loud.Â. Stay up to date with the latest advanced practice news! Myocardial irritability – an initiation of the contraction of the heart muscle by an impulse on a random area of the heart, other than the SA node. After reading this article, you may like to also review your knowled… Decrescendo  begins loudly and becomes softer. S2 is normally louder than S1. Sounds described as “clicks” are extra sounds often heard in those patients with mitral valve prolapsed, aortic stenosis, or those with prosthetic heart valves.  Opening “snaps” are usually caused by mitral stenosis or stenosis of the tricuspid valves. Hypertension increases back pressure on aortic valve, causes increase in loudness of S2. Heart rate and rhythm are normal. Do you struggle with documentation as a nurse practitioner? S2  Use diaphragm of stethoscope. It is followed by assessment of jugular venous pressure (JVP), examining the pulse and checking blood pressure. During the nursing head-to-toe assessment, the nurse will be listening to the heart with a stethoscope. Pulmonic Stenosis delayed emptying of right side can cause splitting of S2. Rhonchi heard upon inspiration in R lung, wheezes auscultated on expiration bilaterally. A syndrome consisting of an absent or faint second heart sound, prominent cardiac impulse and non-regurgitant or forward collapse of the pulse is described. The S3 G can be best heard at the apex as a short, low-pitched sound.  It may possibly be palpated, since it is associated with the ventricle and can create a “thrust” from the heart.  A gallop rhythm is very suggestive of myocardial damage, as stated, and the possible presence of early congestive heart failure.Â. That’s because your heart movements shift the trapped air and cause the scratching sounds. You must use language appropriate to the body system to convey your exam so that your notes make sense to other providers. The cardiovascular system consists of more than just the heart. Save my name, email, and website in this browser for the next time I comment. You must also make sure to cover the components of each system relevant to the patient’s presentation. Normally, the AV valves close at the … Knowing the normal rhythm of the heart as well as the most common abnormal heart sounds will help you identify serious problems in a patient’s heart. The nurse will be assessing S1 and S2 while noting if there are any S1 and S2 splits or extra heart sounds like S3, S4, or heart murmurs. A physical exam of the chest includes both the heart and lungs, which can each be quite complex in themselves. Each module also includes a quiz. Coarse lung sounds ascultated in all lung fields bilaterally. External chest appearance (asymmetry, scars, signs of trauma, cardiac devices). S2 Follow the T wave on the EKG and occurs as the carotid pulse wave fades. Grade VI         Loudest. In the case of a pathological S3, it may be noted with ether vent of damage to the myocardium. Today, however, we will focus on the We will cover other findings, such as circulation to the extremities in the related parts of our documentation series here on ThriveAP. Rubs – Creaky, scratchy noises heard upon cardiac auscultation. Ausculate at the points mentioned previously. For example, there are findings like jugular venous distention and peripheral pulses to note. No accessory muscles used. However, in disease conditions, either or both of these nerves may dominate and produce a fast or a slowed heart rate. It focuses on auscultating normal heart sounds; it is beyond the scope of this article to discuss the pathophysiology of abnormal findings. Documentation of a basic, normal heart exam should look something along the lines of the following: The external chest is normal in appearance without lifts, heaves, or thrills. Basics of Lung Sounds: 201: Bronchovesicular Auscultation Reference This website is intended for use by medical professionals for educational purposes only. Use diaphragm of stethoscope. Heart sounds are caused by the closure of heart valves. 0 Likes. Recording the Physical Assessment Findings, Cardiovascular Assessment in Specific Disease Conditions, Electrical Activity of the Heart Related to Normal EKG. S2 is considered the dub of 'lub-DUB.' Documenting Software Architectures, Second Edition, provides the most complete and current guidance, independent of language or notation, on how to capture an architecture in a commonly understandable form. Extra heart sounds (S3, S4) Displaced PMI; External chest appearance (asymmetry, scars, signs of trauma, cardiac devices) Check out ThriveAP’s guide to documenting the basics of documenting a respiratory exam to complete your notes on examination of the chest. Abnormals on a respiratory exam may include: Respiratory distress (mild, moderate, severe) Decreased or absent breath sounds Documenting a Respiratory Exam - Just the Basics | ThriveAP Physical Assessment Integument. Auscultation is valuable as a basic diagnostic practice used to detect abnormal heart sounds and decide on further course of action. Required fields are marked *. C-V: pulses Heart: rhythm, S1, S2, extra sounds Capillary refill JVD, bruits Edema: S1, S2 auscultated over aortic, pulmonic, erb’s point, tricuspid and mitral areas. Jan 30, 2005. Sounds can range in volume from barely audible to easy to hear with a stethoscope. Indeed, it is described as a gallop. Third Heart Sound S3. This can be a problem because changes in bowel sounds can indicate problems with the patient long before other signs emerge. This course is not designed to make you a cardiologist, but the nurse should be able to recognize and chart anything abnormal in the cardiac cycle. The first and second heart sounds are the result of closing of the atrioventricular and semilunar valves. Have patent relax, remove clothes from waste up, cover with gown, provide for privacy.
