A&P II Lab CARDIO RESPIRATORY

Listening to body movements (like with a stethoscope)

About 75 bpm

119/ 79

(systolic/diastolic)

5 Korotkoff sounds: turbulence when the brachial is occluded

first sounds are loud, last sound is when it disappears or is very softened

pp=40 is normal

By measureing the different pulses at the aprical, radial, and tibial arteries

TV is the amount of aire inhaled or exhaled with each breath under resting conditions (500ml)

Inspirtatory Reserve Volume: amount of air that can be forefully inhaled after a normal tidal volume inhalation (3100ml)

Expiratory Reserve Volume: amount of air that can bbe forecully exhaled after a normal tidal volume exhalation

Residual Volume: about 1200ml

1200+1200= 2400ml



3100+500= 3600ml

• Total lung capacity:
• 

Mean Arterial Pressure: Measures condition of arteries

FEV is forced expiratory volume and FEV1 is the air forcefully expired in the first second



FVC=forced vital capacity, we will use regular VC for manual calculations

these numbers come from chart with averages, or from spirometer measurements

Maximum amount of air that can be exhaled after a maxiumum inspiration (3600-4800ml)





predicted VC comes from chart, average VC measured with spirometer

measures respiratory volumes

Asthma or Emphysemia

(COPD diseases make it harder to exhale. sometimes results in air trapping)

TB, polio, pulmonary fibrosis
