Abstract

A non-invasive blood gas test is carried out by a method that utilizes a venous blood sample together with a pulse oximeter and a plurality of mathematical equations. The method generates the following data points of the blood: (i) the pH level; (ii) the [H+] concentration; (iii) the [HCO₃−] concentration; (iv) the partial pressure of carbon dioxide; and (v) the oxygen saturation level. Mathematical formulas, tables, and chemical equations provide a simple method by which a doctor or other medical professional can easily calculate the blood gas data without the need for an arterial blood sample or specialized machines. Blood gas measurements are obtained from a patient in a faster, safer and less painful manner than tests that require an arterial blood sample. In another embodiment of the present invention, a system for locating a dysfunctional organ in a patient is disclosed.

Claims

1. A system for locating a dysfunctional organ in a patient, consisting of:

(a) a means for monitoring the pH level data of the patient'"'"'s venous blood;

(b) a means for monitoring the patient'"'"'s complete metabolic profile; and

(c) computer programming means for analyzing said patient'"'"'s pH level and said patient'"'"'s complete metabolic profile in order to locate said dysfunctional organ in said patient.

2. A process for locating a dysfunctional organ in a patient, consisting of the steps of:

(a) monitoring the pH level data of said patient'"'"'s venous blood;

(b) monitoring the complete metabolic profile data of said patient; and

(c) analyzing said patient'"'"'s pH level and said patient'"'"'s complete metabolic profile and using said patient'"'"'s PH level and complete metabolic profile together with clinical judgment to locate said dysfunctional organ in said patient.

3. In a first response system adapted for use in a terrorist attack to aid in diagnosis and treatment of respiratory disorders, and acid-base disorders, and to help locate a dysfunctional organ in a patient, the improvement consisting of:

(a) a non-invasive blood gas test is obtained from said patient using a lightweight, portable pH/[HCO₃—

] meter and a hand-held calculator;

(b) the patient'"'"'s venous blood pH level is obtained using the portable pH/[HCO₃—

] meter;

(c) the patient'"'"'s complete metabolic profile is obtained; and

(d) an analysis of said patient'"'"'s venous blood pH level and said patient'"'"'s complete metabolic profile is used, together with clinical judgment, in order to locate said dysfunctional organ in said patient.
