Factors That Influence Blood Pressure
Five factors influence blood pressure: Cardiac output Peripheral vascular resistance Volume of circulating blood Viscosity of blood Elasticity of vessels walls Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls. Blood pressure decreases with decreased cardiac output, peripheral vascular resistance, volume of blood, Read more »
What is Blood Pressure?
Blood pressure is the force of blood exerted against the arterial walls, and is reported in millimetres of mercury (mm Hg). Try turning your kitchen tap on just a little bit, and then full blast. Compare the varying forces of water pressure as you adjust the tap. This comparison will give you a better sense Read more »
Test Yourself
Now that you have completed this chapter, it’s time to test your knowledge. Try to answer the following questions (you may want to review parts of the chapter before answering). Pulse What is the apical pulse rate? Listen to the audio clip of the apical pulse. Count the pulse for 30 seconds and report the Read more »

Radial Pulse Which is the correct technique for measuring the radial pulse? Infant Apical Pulse Which image shows the correct method for measuring the apical pulse on a toddler? Adult Apical Pulse Which image shows the correct method for measuring the apical pulse on an adult?
Respiration Technique
Technique The respiratory rate is counted after taking the pulse rate so that the client is not aware that you are taking it (OER #1). Once you have finished counting the pulse, leave your fingers in place and then begin assessing respiration. Observe the chest or abdomen rise and fall. One respiration includes a full Read more »
Apical Pulse
Apical pulse is auscultated with a stethoscope over the chest where the heart’s mitral valve is best heard. In infants and young children, the apical pulse is located at the fourth intercostal space at the left midclavicular line. In adults, the apical pulse is located at the fifth intercostal space at the left midclavicular line Read more »
Radial Pulse
Technique Use the pads of your first three fingers to gently palpate the radial pulse (OER #1). The pads of the fingers are placed along the radius bone, which is on the lateral side of the wrist (the thumb side; the bone on the other side of the wrist is the ulnar bone). Place your Read more »
What Pulse Qualities are Assessed?
The pulse rhythm, rate, force, and equality are assessed when palpating pulses. Pulse Rhythm The normal pulse rhythm is regular, meaning that the frequency of the pulsation felt by your fingers follows an even tempo with equal intervals between pulsations. If you compare this to music, it involves a constant beat that does not speed Read more »
What is Pulse?
Pulse refers to a pressure wave that expands and recoils the artery when the heart contracts/beats. It is palpated at many points throughout the body. The most common locations to accurately assess pulse as part of vital sign measurement include radial, brachial, carotid, and apical pulse as shown in Figure 3.1. The techniques vary according Read more »
