SPM 100 Clinical Skills Lab 5
Pulse Oximetry andCardiac Monitoring
Daryl P. Lofaso, M.Ed, RRT
Arterial Blood Gas (ABG)
Normal Ranges pH 7.35-7.45 PaCO2 35-45 mmHg PaO2 80-100 mmHg
Oxyhemoglobin Dissociation Curve
Oxygen Transport
Dissolved in plasma: (vol % = 0.0031 (ml O2
/100cm3/mmHg) x PaO2
Bond to Hemoglobin: 1.34 ml of O2/g of Hb x g of Hb x g
of Hb/100 cm3 x % Saturated
Cyanosis
Approximately 5 g/dl of unoxygenated hemoglobin in the capillaries (> 5 gHb / 100ml of blood)
Hypoxemia: Signs and Symptoms
Tachycardia Tachypnea Mental Status Changes

Cardiac Assessment
Ref: Bates 8ed
Heart Sounds S1: “ lub” occurs at the beginning of
systole (mitral and tricuspid close)
S2: “dub” marks the start of diastole,
(aortic and pulmonic close) S3: (ventricular gallop) early signs of
CHF S4: (atrial gallop) pulmonic stenosis,
aortic stenosis, hypertension, MI & cardiomyopathy
Professional Conduct Introduce yourself Explain the procedure /
examination to the patient Ask the patient if they have any
questions Cover the patient with a sheet.
Only expose area examining while performing a procedure/examination
