Concept explainers
If you have sleep apnea, you never get a good night’s sleep. Although you may not realize it, your sleep is briefly interrupted from 30 to more than 100 times each night when you temporarily stop breathing for 10 to 60 seconds (“apnea” means “without breath”). Your blood O2 falls and CO2 rises, causing you to partially awaken, often with a snort. What causes this? Obstructive sleep apnea, the most common form, occurs when muscles that support the tongue and soft tissues of the pharynx relax, causing these tissues to collapse and obstruct the airway. People who snore, are overweight, drink alcohol before bed, or smoke are all more susceptible to sleep apnea. The resulting daytime drowsiness, making it hard to concentrate and dangerous to drive, is bad enough. But the repeated O2 deprivation and CO2 buildup caused by sleep apnea puts your heart at risk as well, so this is a condition to take seriously. How does your body know that you have stopped breathing?

- Which of the following statements about type I respiratory failure is correct? CNS depression with reduced respiratory drive can lead to type I respiratory failure. The partial pressure of carbon dioxide in the arterial blood is above 45 mmHg. It is caused by gas-exchange respiratory failure. Medical ventilator should be used in patients with type I respiratory failure. Hypercapnia occurs prior to hypoxemia.arrow_forwardA event At 11 p.m., a patient is admitted to the Emergency Department (ED) with a respiratory rate of 44 breaths/minute and SaO2 85%. They are anxious with audible wheezes. The patient is immediately given nebulised Salbutamol follow by oxygen via face mask and Hydrocortisone intravenously (I.V). 1. Explain the reason for Intravenous (I.V) Hydrocortisone.arrow_forwardWhich statement concerning the clinical manifestations of asthma is CORRECT? Question 18 options: tachypnea is common and can cause respiratory failure hypoxemia may occur as distal airways narrow bradycardia is a normal homeostatic response to SOB decreased vascular permeability leads to laryngeal edemaarrow_forward
- Bronchiolitis is caused by a bacterial infection. True or False? True Falsearrow_forwardA 9-year-old girl presents to your pharmacy. Her mother tells you that the child has been generally healthy; however, she does seem to become excessively winded when she plays soccer or any other sports. The patient agrees with her mother, telling you that she never feels like she can play as long as the other children because it becomes hard to breathe. You see that her physician has ordered an inhaler for her that will produce bronchodilation via the stimulation of adrenergic receptors on the smooth muscle of the bronchioles. What type of drug below would likely be in this inhaler?arrow_forwardA patient of 50 years old suffers from chronic obstructive bronchitis. Recently, after hypothermia, the patient had a cough with purulent sputum, dyspnea, weakness. On examination: acrocyanosis, blood pressure 140/90, heart rate 100 beats per minute (normally 60-90), respiration is frequent and superficial. At auscultation: there are wet wheezing in the lower lobe of the right lung. Questions: 4. Describe the mechanism of development of this TPP in the patient. 5. Describe the most likely changes in blood gas composition and pH in this case. 6. What signs of adaptive reactions are there in the patient? 7. What other adaptive reactions are typical for this type of TPP?arrow_forward
