設計一個簡單有效的呼吸速率訊號監視器

病患在看急診的過程中，先由護理人員量測病患的脈搏(Pulse)、血壓(Blood Pressure)、體溫(Temperature)、及呼吸速率(Respiration rate)等四大生命徵象，而後再由相關病症分類的醫生作緊急的醫治。四大生命徵象中的前三項(脈搏、血壓、體溫)，目前都已有測試結果精確的相關儀器。例如，血壓計(blood pressure meter)即可精確的量測到脈搏的跳動次數及血壓的收縮壓(Systolic Pressure)和舒張壓(Diastolic Pressure)。另外，四大生命徵象中的呼吸速率，它也是呈現個人整體健康狀況的一項重要指標。為了要提升呼吸計數的正確性，因此本篇論文所提出的呼吸速率(Respiration rate)訊號監視器。本篇論文提出的呼吸速率訊號監視器，它的組成包含下列的三大部份：(a)連結器：主要的任務是擔任系統與呼吸速率感知器(包含影像攝影機)之間的連結工作；(b)訊號擷取器：主要的任務是擷取呼吸速率訊號及影像訊號；(c)訊號傳送器：主要的任務是負責傳送所擷取訊號，其中的呼吸速率訊號是以Wi-Fi傳送，而影像訊號是以網路傳送。本監視器的優點如下：(a)價格便宜；(b)輸出入埠的控制容易完成；及(c)應用程式撰寫容易。為評估本論文所提之呼吸速率訊號監視器的效能，本文作者找了許多同學當作被測試的對象。依據多次測試的結果，證實本篇論文所提出的呼吸速率訊號監視器是一個簡單有效的訊號監視器。

The process of emergency treatment includes two important steps, the first is to measure pulse, blood pressure, temperature, and respiration rate of patient by nurses, and the second is that patient is cured by doctors based on such measured signals. The first three vital signs have been well measured by many accurate instruments. For example, blood pressure meter can accurately measure pulse, systolic pressure, and diastolic pressure. However, few instruments for respiration rate are developed. Thus, a novel respiration rate monitor with simple and effective design is presented in this paper. The proposed respiration rate monitor consists of three major parts: (a) Linker for communication of the main system and respiration rate sensor (including a video camera), (b) Signal capture for capturing respiration rate and video signals, (c) Signal transmitter for transmitting the captured respiration rate by Wi-Fi and video signals by internet to the main system. The advantages of the proposed respiration rate monitor are (a) low cost, (b) easy implementation of input/output control, and (c) easy coding of application software. Experiments show that the proposed respiration rate monitor is a simple and effective respiration rate monitor.
