Claustrophobia - Nursing Case Study
Pathophysiology
• Primary mechanism: Claustrophobia primarily involves hyperactivation of the amygdala, the brain's fear center, leading to an exaggerated fear response when in confined spaces. This heightened activity triggers the fight-or-flight response, causing symptoms like increased heart rate and sweating.
• Secondary mechanism: Dysfunction in the prefrontal cortex, which normally helps regulate emotional responses, further exacerbates claustrophobia. This leads to impaired ability to rationalize fears, making it difficult for individuals to control their anxiety in tight environments.
• Key complication: Persistent claustrophobia can result in avoidance behaviors, significantly impacting daily functioning and quality of life, as individuals may go to great lengths to avoid enclosed spaces.

Section 1
Following her initial assessment, the patient underwent a series of diagnostic evaluations to further understand the underlying factors contributing to her claustrophobia. An MRI of the brain was conducted to rule out any structural abnormalities that might be exacerbating her anxiety symptoms. The results revealed no significant findings, confirming that her claustrophobia is primarily psychological in nature rather than due to an organic brain disorder. Additionally, pulmonary function tests were performed to assess her mild asthma, which could be contributing to her shortness of breath. The tests showed slightly reduced forced expiratory volume (FEV1), indicating that while her asthma is not severe, it may still play a role in her respiratory symptoms during anxiety episodes.
Despite these findings, the patient's condition took a turn with the onset of more frequent panic attacks. These episodes, which occurred even in mildly crowded settings like grocery stores, were characterized by severe hyperventilation, leading to transient hypoxia as evidenced by a drop in her oxygen saturation levels to 88% during an attack. This new complication has increased her reliance on her Albuterol inhaler, although it offers only limited relief from her anxiety-induced symptoms. Her blood pressure and heart rate have also shown more variability, with recordings as high as 160/95 mmHg and 110 bpm during these episodes, further complicating her clinical picture.
The escalation in her symptoms has prompted a multidisciplinary approach, involving her primary care physician, a psychiatrist, and a respiratory therapist. The team is considering adjusting her medication regimen to better address both her anxiety and respiratory needs. Cognitive-behavioral therapy (CBT) is also being emphasized as a critical intervention to help her develop coping strategies for managing her claustrophobia and preventing the cascade of physiological symptoms that arise from her anxiety. The patient's journey continues with a focus on stabilizing her condition and enhancing her quality of life by addressing both psychological and physiological components of her disorder.
Section 2
As the multidisciplinary team continued to address the patient's complex presentation, they opted to focus intensively on her response to interventions, particularly the integration of cognitive-behavioral therapy (CBT) and pharmacological adjustments. The patient was started on a low-dose selective serotonin reuptake inhibitor (SSRI) to help manage her anxiety symptoms, alongside scheduled sessions with a CBT-trained therapist. Initial feedback from the patient indicated a slight reduction in the frequency of her panic attacks, though she still reported significant anxiety in confined spaces. During her therapy sessions, she began to identify specific triggers and develop personalized coping mechanisms, such as controlled breathing techniques and visualization exercises, which she reported using to moderate success.
However, as the therapy progressed, the patient experienced a sudden increase in her asthma-related symptoms, particularly notable during therapy exercises that involved exposure to anxiety-inducing scenarios. These stress tests, designed to gradually desensitize her to triggers, occasionally resulted in acute episodes of breathlessness and wheezing, despite her regular use of the Albuterol inhaler. Pulmonary function tests conducted during these episodes showed a further decrease in FEV1, now at 70% of the predicted value, suggesting an exacerbation of her respiratory condition. Her oxygen saturation levels also demonstrated increased variability, frequently dropping to 90% during these stress tests, thereby complicating her therapeutic progress.
The team, recognizing these challenges, decided to adjust her asthma management plan in tandem with her anxiety treatment, introducing a low-dose inhaled corticosteroid to reduce airway inflammation. This adjustment aims to provide a more stable respiratory foundation as she continues her CBT. The clinical reasoning underscores the importance of a balanced approach, addressing both psychological and physiological factors to improve her overall quality of life and prevent further complications. The patient's journey remains dynamic, with the team closely monitoring her response to these interventions, ready to adapt strategies to better meet her evolving needs.
Section 3
As the patient continued with her integrated treatment approach, the multidisciplinary team observed a concerning change in her status. During a routine follow-up, the patient reported increased fatigue and difficulty sleeping, which she attributed to her heightened anxiety and respiratory challenges. A comprehensive assessment revealed elevated blood pressure at 145/92 mmHg, increased heart rate at 98 beats per minute, and persistent respiratory symptoms despite the adjusted asthma regimen. Her oxygen saturation, while generally stable at rest, still showed dips to 88% during mild exertion, indicating ongoing respiratory compromise.
Further diagnostic evaluations were conducted to elucidate these new symptoms. A chest X-ray ruled out any acute pulmonary infection, but a subsequent spirometry test confirmed a further decrease in lung function, with FEV1 now at 65% of the predicted value. Additionally, routine blood work indicated elevated eosinophil levels, suggesting an allergic component contributing to her asthma exacerbation. These findings prompted the team to consider additional interventions, including a potential adjustment to her inhaled corticosteroid dosage and the introduction of a leukotriene receptor antagonist to better manage her asthma symptoms.
The team recognized that these developments required a nuanced approach, balancing the need to control her respiratory symptoms while continuing to address her anxiety. Emphasis was placed on refining her CBT techniques to incorporate low-impact physical exercises that could improve her overall stamina and help mitigate her anxiety-related exhaustion. This dual focus on optimizing both her psychological and physiological health remains critical, as the team aims to stabilize her condition and improve her quality of life. Close monitoring will continue, with the team prepared to further tailor her treatment plan based on her evolving clinical picture.
Section 4
As the multidisciplinary team continued to monitor the patient, they noted a concerning change in her clinical status. Despite the adjustments to her asthma management plan, the patient began experiencing episodes of dizziness and palpitations, particularly during periods of mild exertion. These symptoms were accompanied by an increased frequency of anxiety attacks, which she described as overwhelming and debilitating. Upon further evaluation, her vital signs revealed a heart rate that intermittently spiked to 110 beats per minute, and her blood pressure fluctuated more widely, reaching highs of 150/95 mmHg. In light of these developments, the team acknowledged the need for a more comprehensive cardiovascular assessment.
An ambulatory Holter monitor was employed to gain insights into her heart rhythm over a 24-hour period. The results indicated frequent premature ventricular contractions and occasional episodes of supraventricular tachycardia, suggesting an underlying cardiac arrhythmia potentially exacerbated by her anxiety and respiratory challenges. Additionally, the patient's serum cortisol levels were noted to be elevated, reflecting a stress response that further complicated her clinical picture. These findings prompted the cardiology team to consider the introduction of a beta-blocker to manage her heart rate and reduce the occurrence of palpitations, while also being mindful of potential interactions with her asthma medications.
Recognizing the intricate interplay between her anxiety, respiratory, and cardiovascular symptoms, the team emphasized the need for an integrated treatment strategy. They proposed enhancing her cognitive behavioral therapy to include stress reduction techniques specifically targeting her cardiac anxiety. Furthermore, they planned to introduce a graded exercise program under close supervision to safely build her cardiovascular endurance without triggering respiratory distress. The team remains vigilant, prepared to refine her treatment plan further, as they aim to stabilize her condition and improve her overall well-being.
Section 5
As the multidisciplinary team continued to monitor the patient, they observed a change in her status that prompted further investigation. Despite the introduction of a beta-blocker, the patient reported an increase in fatigue and an occasional sensation of lightheadedness. During a follow-up visit, her blood pressure was noted to have decreased to 105/65 mmHg, and her heart rate had stabilized at 85 beats per minute, suggesting an initial positive response to the beta-blocker. However, her respiratory symptoms showed minimal improvement, and she continued to experience frequent anxiety attacks, particularly in enclosed spaces, which exacerbated her claustrophobia.
The team decided to perform a pulmonary function test to reassess her asthma control in light of her ongoing symptoms. The test revealed a slight decrease in her forced expiratory volume in one second (FEV1), suggesting suboptimal asthma management. In response, her asthma management plan was adjusted to include a long-acting inhaled corticosteroid and a leukotriene receptor antagonist to better control her symptoms. Additionally, her cognitive behavioral therapy sessions were intensified, with a focus on desensitization techniques to address her claustrophobia and anxiety during potential triggers like medical appointments.
Despite these adjustments, the patient developed new complications, including sleep disturbances and increased reliance on her rescue inhaler, which the team attributed to the heightened stress and anxiety she was experiencing. Her serum cortisol levels remained elevated, reinforcing the need for a holistic approach to her care. The team recommended a consultation with a psychiatrist to explore the potential benefit of anxiolytic medication, carefully considering the risk of respiratory depression. This comprehensive and multidisciplinary strategy aimed to address the interconnected nature of her conditions, paving the way for a more stabilized clinical picture and improved quality of life.
