Summary Introduction
To review:
The benefits of breathing in the paper bag.
Introduction:
Hyperventilation is a situation, in which the person has an attack of anxiety. It is a situation where the person starts to breathe very fast. In this situation, there is an imbalance of healthy breathing by a human. In this condition, the person exhales more than inhaling. This causes an instant reduction of carbon dioxide in the body.

A 23-year-old woman with a history of asthma was brought to the emergency
department by ambulance. She was extremely short of breath. Her level of
consciousness was diminished greatly, and she was only able to respond to questions
with nods or one-word responses. She had a weak cough, with nearly inaudible
breath sounds. After drawing blood gases, she was placed on supplemental oxygen.
Vital signs: heart rate, 160 bpm; blood pressure, 120/84 mm Hg; temperature, 37°C;
and respiratory rate, 36/min. Her initial blood gas and total hemoglobin results were
as follows:
pH = 7.330
pCO2 = 25 mm Hg
pO2 = 58 mm Hg
HCO3 = 13 mmol/L
tHb = 12.4 g/L
QUESTIONS:
1. What is the patient’s acid-base and oxygenation status?
2. What is the cause of the acid-base disturbance?
3. Does asthma typically present in this matter?
4. What clinical findings are most indicative of this patient’s impending
failure?
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.
Anaphylaxis is a life-threatening allergic reaction that can cause a rash, symptoms of shock, low blood pressure, and closed airways. An autoinjector can be used to administer synthetic epinephrine to a patient suffering from anaphylaxis. What are the FOUR effects of epinephrine that can help save a person’s life?
Bronchioles dilate.
Bronchioles close.
Breathing rate decreases.
Breathing rate increases.
Blood pressure increases.
Blood pressure decreases.
Heart rate increases.
Heart rate decreases.
Record your answers in ascending (lowest to highest) order.

- Randi Marchant, a 42-year-old waitress, was vacuuming the family room when she felt a pain in her chest again. She also felt like her heart was being squeezed. This was the third time today that she felt this pain and pressure, but this time, it really hurt. Feeling short of breath, she stubbed out the cigarette she had left smoldering in the half-filled ashtray by the couch. Randi’s husband, Jimmy, and stepdaughter Melonie had pestered her until she finally took time off work to see her doctor. Dr. Harris found that her blood pressure was 158/88. Randi told herself it was probably due to the noon rush stress at work and didn’t take it seriously, At least her cholesterol test was only 30 points above average this time. It had been slowly coming down, even though she cheated on her diet and ate lots of high-fat foods. Another wave of pain tightened its icy fingers around her heart, and the pain moved up into both sides of her jaw. Randi thought, “Probably just heartburn.” (Randi often…arrow_forwardDave is a 41-year-old male who was referred by his primary care physician after presenting to the ER with difficulty breathing. Dave’s physician was unable to find a medical explanation for his symptoms, which left Dave feeling confused, stressed, and angry. Over the last 6 months, Dave has had several instances where he felt an intense fear that would reach a peak within a few minutes. During these instances, he would also experience sweating, heart palpitations, chest pain and discomfort, and shortness of breath. At times, Dave worried that might die. As a result, Dave has persistent worry about having another attack. In addition, he has begun to avoid unfamiliar places and people where it may be difficult to get help in the event of another panic attack. The panic and associated avoidance are significantly impacting Dave’s life as he has been turning down social invitations, making excuses to stay at home whenever possible, and relying on his wife to drive their children to their…arrow_forwardDave is a 41-year-old male who was referred by his primary care physician after presenting to the ER with difficulty breathing.
