Arterialbloodgas - Study guides, Class notes & Summaries

Presentation outline • Objectives • Introduction • Definition of Arterial Blood Gases • Components of ABGs • Indications of ABGs • General Approach to ABG Interpretation • Case Studies • Take Home Message Objectives  Understand ABG and its terms  Know indications for ABGs  Understand General approach to ABG Interpretation  Clinical use of ABG’s  Be able to diagnose Case studies using ABGs Introduction

ABG • Determines the blood pH and the partial pressures of O2 and CO2 • Measures the respiratory and metabolic effects of the disease on the acid-base balance • Cannot be determined by clinical assessment alone ↑CO2 ↑RR = ↓CO2 Respiratory Effects CO2 + H2O H2CO3 HCO3 - + H+ pH = -log [H+] ↑CO2 = ↑H+ = ↓pH

NCSBN–Lesson 8B:Respiratory System Study Guide Upper Respiratory System Disorders The upper respiratory system consists of the nose, mouth, pharynx and larynx. It allows air flow into and out of the lungs as it warms, humidifies and filters inspired air.This section will review upperrespiratorydisorderssuchasrhinitis,sinusitis,pharyngitis,tonsillitis,peritonsillarabscess, laryngitis, vocal cord paralysis, upper respiratory tract infections and croup syndromes.
