Pulse & Respiration Unit III: Ch. 19

Pulse & Respiration p. 321 Counted together, first pulse, then respirations Keep fingers on pulse while counting respirations Tell pt you are taking her/his pulse and continue counting respirations after obtaining pulse – why? Respirations are partly voluntary and if the pt knows they are counted, the breathing pattern is altered Count both for a full minute! Need 2nd hand on watch for this

Pulse p. 321 Pressure of blood against an artery wall when heart beats (pulse) and relaxes (no pulse) Easier felt in arteries close to surface that can be pressed against a bone Is the same in all arteries throughout body Indication of how well the cardiovascular system works Stethoscope p. 322 Used to listen to sounds inside body by intensifying sounds Parts: see Figure 19-3 p. 323 (need to know) ALWAYS clean earpieces, diaphragm, bell and tubing with alcohol or cavy wipes before and after use Used for obtaining apical pulse, blood pressure, listening to heart, lungs, abdomen See p. 324: Guidelines for using a stethoscope! Inspect for damages Clean, clean, clean Always use directly against skin, not over clothing!

Radial pulse p. 322 Most commonly measured pulse Measured at radial artery on wrist, count for 1 full minute Pt arm should be in comfortable position, palm down, arm resting on flat surface Use tips of your fingers, never thumb Only used on conscious patients Unconscious pt: carotid artery or apical pulse See Figure 19.1 for common pulse sites Record as: beats per minute (bpm) ex. Pulse 85bpm R

Pulse rate/character p. 322 Procedure 37: counting radial pulse p. 323 Rate/speed: see Table 19.1 for normal pulse rates; need to know adult!!!! Adult: 60-80 General: the smaller the body, the higher the pulse rate ex. Hummingbird 1000bpm Bradycardia: unusually slow pulse rate; below 60 beats per minute (bpm) Tachycardia: unusually fast pulse rate; over 100 bpm Character: Rhythm: regular or irregular (normal: regular) Volume/fullness: weak, strong, thread Always report any abnormalities to the nurse: Bradycardia Tachycardia Irregular pulse Threaddy/ weak pulse Procedure 37: counting radial pulse p. 323

Influencing factors p. 322 Rate can be affected by: Disease Emotions Age Exercise Elevated temp Gender Position Physical training Low temp Drugs

Apical pulse p. 322 Measured by counting heart contractions using a stethoscope Measured at the apex (tip) of the heart at left side of front of chest, for 1 full minute Rate should be same as pulse When documenting: write AP after the bpm ex. 80 bpm AP Sound: lub/dub Lub: contraction of ventricles pushing blood out Dub: relaxation of ventricles when they fill back up with blood Used when: There is a pulse deficit (see next slide) Before RN gives heart rate altering medicine In children when rapid pulse rate is difficult to count at radial artery Everyone 12 months or younger Irregular radial pulse or uncertain of accuracy of radial pulse

Apical-radial pulse rate p. 324 Comparing apical and radial pulse rate Should be the same If heart contracts to weekly, can’t send enough blood through the arteries for pulse to be felt One person takes apical pulse while other person takes radial pulse see Procedure 38 p. 324 Difference between apical and radial pulse = pulse deficit; found in some forms of heart disease

How to record pulse: ex. 76 beats per minute, regular, strong _____________/minute, ____________, _________________

Respirations p. 325 Function: supply O2, discard CO2 If ineffective: less O2 for body, too much CO2 in body Cyanosis: bluish or dusky color of the skin 2 parts of respiration: Inspiration (inhalation), expiration (exhalation) Breathing patterns: Normal: regular; 12-20 breaths per minute Tachypnea: rapid, shallow Shallow: breaths only fill lungs partially Apnea: period of no respirations (ex. Sleep apnea) Dyspnea: difficult or labored breathing Cheyne-Stokes respiration: period of dyspnea followed by periods of apnea Stertorous: snoring-like respirations Rales (crackles): moist respirations; air has to bypass mucus / wet passage ways; common in dying pt Wheezing: difficult breathing by whistling or sighing sound due to narrowing of bronchioles (ex. asthma)

What to look for p. 325 Check respirations for: Rate: number of respirations per minute Rhythm: should be regular/ even Symmetry: chest should expand and retract equally Volume: depth of respiration Character: regular, irregular, shallow, deep, labored (difficult) Normal: even, unlabored Rate: see norms in Table 19-2 p. 326 Normal for adult: 12-20 respirations per minute Accelerated: over 25 respirations per minute Too slow: under 12 per minute Report: accelerated or too slow breathing (i.e. Over 25 or under 12) Affected by: Illness Emotions Elevated temp Gender Age Exercise Position Drugs

How to measure p. 325 How to record: Procedure 39 p. 326 Continue counting respirations after pulse, without letting pt know you are counting respirations Record rate, depth and regularity eg. 18 respirations per minute, unlabored, regular How to record: Ex. 22 breaths per minute, even, unlabored _____________________/minute, ____________, _______________

Wash hands, get supplies (eg. Paper, pen, watch) Introduce yourself by name, call pt by name, explain that you will measure her/his pulse, lock bed/WC if in bed or WC Privacy curtain Wash hands, get supplies (eg. Paper, pen, watch) Wash hands before touching pt Position pt’s arm comfortably, palm down Position your fingertips on radial artery Use 2nd hand on watch, say start, count pulse for 1 full minute (remember number), say stop Immediately, count respirations for 1 full minute, say stop Call bell in reach? Pt feels ok or needs anything else? Privacy curtain open Wash hands Record pulse and respirations as: Pulse: ____________ beats per minute, regular, strong Respirations: _______________breaths per minute, even, unlabored
