ARTERIAL PUNCTURE PROCEDURES Flashcards
used to collect blood specimen for arterial blood gas (ABG) analysis to manage
cardiopulmonary disorders and maintain the acid-base balance of the body
Arterial puncture
ideal specimen for the respiratory function evaluation due to the consistency of its composition and high oxygen content.
arterial blood
A measure of acidity or alkalinity of blood (acidosis or alkalosis)
PH
Percent O2 bound to hemoglobin
O2 saturation
Partial pressure of CO2 dissolved in arterial blood
PaCO2
A calculation of non respiratory part of acid-base balance
Base excess
Partial pressure of O2 dissolved in arterial blood
PaO2
A calculation of non respiratory part of acid-base balance
Base excess
A measure of bicarbonate in blood
HCO2
Normal Range of HCO2
22–26 mEq/L
Normal Range of PaO2
80–100 mm Hg
Normal Range of pH
7.35– 7.45
Normal Range of Base excess
(-2)–(+2) mEq/L
Normal Range of PaCO2
35–45 mm Hg
Normal Range of O2 saturation
97%– 100%
most commonly used site and located in the thumb side of the wrist.
Radial Artery
located in the groin lateral to the pubic bone.
Femoral Artery
located in the medial anterior of the
antecubital fossa.
Brachial Artery
is performed to diagnose respiratory disorders.
Arterial Blood Gas (ABGs)
Arterial Blood Gas (ABGs) test provides
information about
(1) oxygenation,
(2) ventilation, and
(3) acid-base balance which helps in the
management of the disease.
