Patient Health Monitoring Literature Review

CHAPTER TWO

LITERATURE REVIEW

2.1 INTRODUCTION

In this chapter, the concept of patient health monitoring will be reviewed; the theory of components and existing works will be reviewed also.

2.2 OVERVIEW OF PATIENT HEALTH MONITORING.

According to Hudson L.Respir.Care 1985, patient health monitoring systems can be defined as “repeated or continuous observations or measurements of the patients, their physiological functions, and the function of the life support equipment for the purpose of guiding management decisions including when to make therapeutic interventions and assessments of these interventions” [1].

Patient health monitoring is needed in situations where the patient is;

• In the case of a drug overdose or anesthesia

• In a life threatening condition, where there is a warning of a heart attack

• In a critical

The main purpose was creating an ECG monitoring and alert system that detects cardiac abnormalities like tachycardia and bradycardia. The downside to this project was its need for medical professionals for operation

[4] Proposed a heart rate monitor using a low cost microcontroller, AT89C52, He measured heart rate from the fingertip using infra-led transmitter and receiver sensor box. The rate is then averaged and displayed on a text based LCD, but does not have voice output to aid visually impaired persons.

[5] Proposed a microcontroller based heart rate monitor using fingertip sensors. The design uses the optical technology to detect the flow of blood through the fingertip.
