Photoplethysmogram (Ppg) To Estimate Respiratory Rate

Case Study: D.Q. is a 57-year-old male who worked in a water treatment plant for many years. He also smoked heavily for approximately 30 years. He has been diagnosed with COPD. During an extremely hot summer, he arrived at the emergency department in severe exacerbation of the COPD. The patient’s heart rate is 123, blood pressure is 163/90, respiratory rate is 34, oxygen saturation is 86% on 2 L NC, and temperature is 37.5 celsius.

A normal respiratory rate is between 12 & 20 breaths per minute, this can be recorded manually by using a clock. If you respiratory rate drops below the normal measurements

In conclusion, the respiratory and cardiovascular systems are directly related in a complex manner, relying on one another to perform their physiological functions. Only together can both systems work to maintain the body’s internal balance, this is evident when physical demand is higher than normal. In order to meet this demand, the heart must pump more nutrient-rich blood around the body; however it needs oxygen to do this, in response the

At higher altitudes respiration rate is increased which leads to increases in ventilation (possibly a five-fold increase from sea level). Chemoreceptors in the arterial blood vessels are stimulated to signal the brain to increase ventilation. The increase in ventilation is associated with increased breathing frequency and tidal volume.

I and my colleague systematically assessed the patient using rapid assessment (ABCDE) and observation of vital sign. ABCDE mean assessing patient Airway, Breathing, Circulation, Disability and Exposure. Vital signs consist of blood pressure, pulse temperature, and respiration rate. They are essential basic observation that provides information on which clinical decisions are based and for identifying when any nursing or medical intervention is required according to Lina and Barbara (2008 p59).

Both rapid, shallow breathing patterns and hypoventilation effect gas exchange. Arterial blood gases will be monitored and changes discussed with provider. Alteration in PaCO2 and PaO2 levels are signs of respiratory failure. Patient’s body position will be properly aligned for optimum respiratory excursion, this promotes lung expansion and improved air exchange. Patient will be suctioned as needed to clear secretions and maintain patent airways. The expected outcome is that the patient’s airway and gas exchange will be maintained as evidence by normal arterial blood gases (Herdman,

The Ventilatory threshold was reached at 5 minutes or stage 3 for patient 92 C. The ventilatory threshold is important because it indicates the point at which the blood lactate acid increases non-linearly. It indicates that there is an increase in the lactate acid level in the blood as well as the excess carbon dioxide (Kenny et al., 2015). The increase in carbon dioxide will stimulate chemoreceptors to increase ventilation. The ventilatory threshold is related to the anaerobic threshold which refers to the increase in carbon dioxide and indicates that the body has shifted towards anaerobic metabolism (Kenny et al., 2015).

The authors then share their analysis on the changes of heart rate and GSR at the many different points throughout their study.

hypotensive with a blood pressure of 82/44 mm Hg. His respiratory rate is 28 breaths/min

In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until

2. Physiological state in defined as “the condition or state of the body or bodily functions”. This can be measured when we perform our observations. By measuring a patient’s respiratory rate, oxygen saturations, peak flow (in asthma patients), pulse rate, systolic and diastolic blood pressure, core temperature, blood sugar, pupil reaction and Glasgow coma scale. All these combined measurement can give us an insight into the patient’s health or Physiological state.

Once the patient was correctly hooked up to the EKG the BIOPAC Student Lab Program was started. Lesson five is the one we used for this experiment and once it had been chosen we label it and started the experiment. There were four conditions we needed to measure; the first being lying down. The subject was lying down relaxing on the cot. We clicked record and let it run for 20 seconds. The data resembled the chart below. If it did not we would have had to repeat the steps until it did.

The right side of heart will increase in size as the muscle builds up and the heart rate will increase due to compensation for the left ventricle. With auscultation, the lungs will sound crackly from the liquid in the alveoli and interstitial space and when assessing respiration rate it is likely to be above thirty breaths per minute (Lewis et al., 2014). The patient may report that they are experiencing dyspnea, nocturia, fatigue, and a productive coughing. They may appear anxious and their skin may look pale (Lewis et al., 2014).

Following the principles of patient physical examination by Lawson and Peate (2009), her breathing would be described as tachypnoeic with a respiratory rate of 28 breaths per minute. There were equal rise and fall of the chest with no abnormal sounds on auscultation. Her oxygen saturation levels and end-tidal co2 were below normal range respectively at 93% and 3.8 kilopascals (kPa), whilst the capnography waveform showed signs of hyperventilation (South Western Ambulance Service, 2013). Her heart rate would be defined as regular and tachycardic for having
