Introduction to respiratory system

Structure of respratory system

• External (Pulmonary) respiration: absorption of O2 and removal of CO2 from the body.

• Internal (tissue) respiration: utilization of O2 and production of CO2 by cells and the gaseous exchanges between the cells and their fluid medium.

• What is the normal respiratory rate in humans: 16-20 times per minute in adults. 

• Children breathes more superficially and therefore have a higher respiratory rate.

Which of the following is the smallest functional unit of the lung?

:arynx anatomy

Larynx

AKA voice box 

Short section of the airway that connects the laryngopharynx and trachea.

Located in the anterior portion of the neck, just inferior to the hyoid bone and superior to trachea.

:arynx internal anatomy

Epiglottis:

 a flap of elastic cartilage that acts as a switch between the trachea and the esophagus.

Inferior to the epiglottis, is the thyroid cartilage, often known as Adam’s apple, visible in adult males.

Trachea 

AKA windpipe

5 inch long tube made up of C-shaped hyaline cartilage rings.

Connects the larynx to the bronchi and allows the air to pass through the neck and into the thorax.

Function: to provide a clear airway for air to enter and exit the lungs.

Lungs 

A pair of large, spongy organs found in the thorax lateral to the heart and superior to the diaphragm.

Each lung is surrounded by a pleural membrane that provides the lung with space to expand.

The left lungs are slightly different that right in size and shape due to the heart pointing in the left side of the body.

2 lobes in the left and 3 lobes in the right.

Chronic Obstructive Pulmonary Disease

A board classification of disorder including emphysema, chronic bronchitis and asthma. 

Irreversible condition associated with dyspnea on exertion and reduced airflow in or out of the lung.

4th non communicable disease in the world according to recent study. 

Risk factors of COPD

Pneumothorax and pleural effusion- diagnosis and management with MCQs

left sided pneumothorax

PNEUMOTHORAX

Pneumothorax is the presence of air in the pleural space.

Two types

• Traumatic pneumothorax
• Spontaneous pneumothorax

• Results from penetrating or non-penetrating chest injuries.

• Transthoracic needle aspiration
• Thoracentesis
• The insertion of central intravenous catheters

• Primary Pneumothorax

1. No evidence of overt lung disease.
2. Due to rupture of a small subpleural emphysematous bulla or pleural bleb, or the pulmonary end of a pleural adhesion
3. Occur almost exclusively in smokers
4. one-half of patients will have a recurrence

• Secondary Pneumothorax

1. Underlying lung disease, most commonly COPD and TB;
2. also seen in asthma, lung abscess, pulmonary infarcts, bronchogenic carcinoma, all forms of fibrotic and cystic lung disease

Tension pneumothorax

• Results from a wound in the chest wall which acts as a valve that permits air to enter the pleural cavity but prevents its escape
• Intrapleural pressure rises to well above atmospheric levels. 
• The pressure causes mediastinal displacement towards the opposite side, with compression of the opposite normal lung 
• Impairment of systemic venous return, causing cardiovascular compromise

Closed pneumothorax

• Communication between the airway and the pleural space seals off
• mean pleural pressure remains negative
• reabsorption of air, re-expansion, infection is uncommon

Open pneumothorax

• Communication fails to seal and air continues to pass freely
• Occur following rupture of an emphysematous bulla, tuberculous cavity or lung abscess into the pleural space
• Infection is common

Clinical Features of tension pneumothorax

• sudden-onset unilateral pleuritic chest pain or breathlessness
• larger pneumothorax (> 15% of the hemithorax) results in decreased or absent breath sounds
• combination of absent breath sounds and resonant percussion note is diagnostic of pneumothorax.

• Inspection

• Tachypnoea (pain, deflation reflex)

• Palpation

• ↓Expansion

• Percussion

• Resonant or hyper-resonant

• Auscultation

• Absent breath sounds

Tension pneumothorax also causes

• Deviation of trachea to opposite side
• Tachycardia and hypotension
• Cyanosis 

Investigations for pneumothorax

• Chest X-ray

• Sharply defined edge of the deflated lung with complete translucency
• Extent of any mediastinal displacement and reveal any pleural fluid or underlying pulmonary disease.

• CT scan
•  In doubt, distinguish bullae from pleural air.

Treatment of tension pneumothorax

• Primary pneumothorax with lung edge < 2 cm from the chest wall, not breathless requires no intervention.

Percutaneous needle aspiration of air 

• In young patients with a moderate or large spontaneous primary pneumothorax
• Intercostal tube drainage
• In those over 50 years old and those with respiratory compromise

Surgical pleurodesis 

• Recommended following a second pneumothorax
• should be considered following the first episode of secondary pneumothorax if low respiratory reserve makes recurrence hazardous. 

• Pleurodesis can be achieved by pleural abrasion or parietal pleurectomy at thoracotomy or thoracoscopy.
• Prevents recurrences

Post Chest Tube monitoring: what to look for after keeping a chest tube

• After 24 hours;  if lungs reinflated and no bubblingremove drain
• Continuing bubbling after 5- 7days  is indication of surgery
• High flow O2 supplement- may speed resolution
• If bubbling stops before full inflation of lung then tube is either blocked , kinked or displaced
• Pleural Effusion 

Pleural effusion:

Pleural Fluid

• Excessive accumulation of fluid in the pleural space. 
• Detected clinically, when ≥ 500 mL is present.
• Produced and absorbed at a rate of 15mL per day
• Each pleural space contains 10mL of fluid

Causes of pleural effusion:

Pathophysiology of pleural effusion:

Fluid enters the pleural space:

• from the capillaries in the parietal pleura
• from the peritoneal cavity via small holes in the diaphragm
• Fluid removed via the lymphatics situated in the parietal pleura. 

lymphatics have capacity to absorb 20 times more fluid than is normally formed.

Pleural fluid accumulates when:

pleural fluid formation >pleural fluid absorption. 

Exudative or Transudative

Alteration of hydrostatic and/or oncotic factors Increases the formation or decreases the reabsorption Transudate

Direct or cytokine induced pleural membrane and/or vascular damage Increased capillary permeability Exudate

Types of pleural effusion:

Transudative effusion

1. Congestive Heart failure
2. Cirrhosis 
3. Pulmonary embolization 
4. Neoplastic syndrome
5. Constrictive pericarditis
6. Hypothyroidism

Exudative effusion:

1. Bacterial pneumonia (common)
2. Tuberculosis
3. Carcinoma of the bronchus
4. Pulmonary infarction
5. Autoimmune 
6. -Rheumatic diseases
7. – SLE 

Clinical features of pleural effuion:

• Shortness of breath
• Chest pain, especially on breathing in deeply (pleurisy, or pleuritic pain)
• Fever
• Cough

How Patient Presents in pleural effusion?

History in pleural effusion

• Pain on inspiration and coughing
• Often  asymptomatic
• Pleurisy 

Examination finding in pleural effusion:

1. Chest wall movement : Reduced in affected side 
2. trachea and mediastinum shift away from affected side
3.  With massive effusion (>1000ml)]
4. Percussion note: Stony dull 
5. Breath sounds: Vesicular
6. (Reduced or absent)
7. Vocal resonance: Reduced or absent

On Chest Examination of pleural effusion following findings  can be found:

• Bronchial breathing may be present
• Expansion ↓
• Percussion stony dull
• Air entry ↓
• Vocal resonance ↓
• With massive effusion (>1000ml) trachea and mediastinum shift away from affected side

Diagnostic Approach in pleural effusion

Light’s criteria for Exudative Effusion

• Pleural fluid protein: serum protein >0.5
• Pleural fluid LDH: serum LDH >0.6
• Pleural fluid LDH > 2/3 upper limit of normal for serum
• Investigations 
• Serum
• CBC
• LDH
• protein
• Coagulation studies (PT, PTT, INR )

Pleural fluid analysis for pleural effusion:

• Note color and consistency
• Chemistries: Protein, albumin, LDH, glucose, pH
• Cell count with differential
• Microbiological stains and culture 
• Cytology

Pleural fluid finding in effusion

Lateral decubitus x ray in pleural effusion:

• Demonstrates fluidity
• Suggest for thoracentesis if fluid layer > 1cm. 
• Transudates
• Usually resolve with treatment of underlying cause
• Therapeutic thoracentesis in persistent larger effusion
• Pleurodesis, shunts, or placement of a indwelling pleural catheter for palliation

Treatment of pleural effuusion:

• Simple Parapneumonic Effusion

• Antiobiotics
• Selected base on causing organism
• Generally anaerobic coverage
•   ( clindamycine, imipenem, extended spectrum penicillin )
• Close observation

• Complicated Parapneumonic Effusion
• Antiobiotics

• Early thoracostomy tube drainage
• Surgical decortication if extensive pleural thickening, fibrous organization, and /or multiple loculations.
• Malignant Pleural Effusion
• 2nd most common type of exudative pleural effusion (lung carcinoma, breast carcinoma, & lymphoma)
• Diagnosis: cytology of the pleural fluid
• If cytology is negative, thoracoscopy is done if malignancy is suspected

Management  of pleural effusion

• Symptomatic treatment 
• Tube thoracostomy ( sclerosing agents : doxycycline )
• Plurodesis when there is rapid reaccumulation of fluid
• Insertion of indwelling pleural catheter

Complications of pleural effsuion if untreated

1. empyema
2. constrictive fibrosis
3. Sepsis
4.  lung cancer

Nursing care for pleural effusion and chest tube inserted patient

• Observe for infection, local inflammation
• Check dressing
• Check if tube is blocked
• Mobilization care
• Check for amount and color of drainage
• Pain management
• Ensure breathing and lung reexpansion in case of collapse
• Prevent clamping
• Ensure positioning

What is Comprehensive Abortion Care?

Introduction

Comprehensive Abortion Care (CAC) is a patient-centered, comprehensive approach to abortion that includes services ranging from counseling and medical procedures to post-abortion care and support. It prioritizes women’s health, safety, and well-being while protecting their reproductive rights. CAC addresses not only the medical elements of abortion, but also the social, emotional, and psychological issues that influence a woman’s decision-making process. This article discusses the significance of comprehensive abortion treatment and its components.

Understanding Comprehensive Abortion Care

Abortion Care that is Comprehensive goes beyond the typical focus on medical procedures. It recognizes that women’s needs and experiences vary, and that these must be taken into account while providing abortion services. CAC’s basic components are as follows:

Safe and Legal Abortion Services:

CAC guarantees that women have safe and legal abortion methods available to them. Abortions are performed in a clinical setting by qualified healthcare professionals in accordance with medical standards and guidelines. Legal frameworks must protect women’s right to choose abortion without fear of legal prosecution.

Pre-Abortion Counseling:

Proper counseling is crucial to ensure that women make informed decisions about their reproductive health. It involves providing accurate information about abortion methods, potential risks, and available support services. Counseling also addresses emotional and psychological concerns, helping women feel confident in their choices.

Medical Procedures:

Proper counseling is essential to ensuring that women make educated reproductive health decisions. It entails disseminating correct information regarding abortion methods, dangers, and available support services. Counseling also tackles emotional and psychological issues, allowing women to feel more confidence in their decisions.

Post-Abortion Care:

Comprehensive care goes beyond the actual abortion. Follow-up consultations to check on physical healing and treat any issues are part of post-abortion care. To assist women in overcoming any potential emotional difficulties, counseling and emotional support are also available.

Contraceptive Services:

Access to contraceptive advice and services is a component of CAC in order to avoid future unwanted pregnancies. Based on their health, lifestyle, and reproductive objectives, this assists women in selecting an effective contraceptive technique.

Respect for Women’s Autonomy and Rights:

Women’s right to make their own decisions about their reproductive health is upheld by CAC. It acknowledges that every woman has a special situation, and that her decisions should be respected without bias or pressure.

Importance of Comprehensive Abortion Care

Here is teh importance of CAC explained in detail.

Promoting Women’s Health and Well-being:

Women’s health and safety are given top priority by CAC, lowering the likelihood of unsafe and unauthorized abortions. Abortion is a safe medical procedure with few risks when done by qualified specialists.

Reducing Maternal Mortality and Morbidity:

Abortions performed unsafely play a substantial role in maternal mortality and morbidity rates around the world. By guaranteeing that women have access to secure abortion services, CAC plays a crucial part in lowering these dangers.

(ads1)

Supporting Reproductive Rights:

An essential reproductive right is the availability of comprehensive abortion care. Women are given more control over their bodies and destinies thanks to CAC, which promotes gender equality and women’s empowerment.

Addressing Stigma and Emotional Well-being:

The emotional and psychological effects of abortion are acknowledged by CAC. It aids women in overcoming any stigma or emotional difficulties they may experience by offering counseling and support.

Preventing Unintended Pregnancies:

Contraceptive services are a part of CAC, which supports family planning and reproductive health by assisting women in preventing future unplanned pregnancies.

Happy family

Conclusion

Comprehensive abortion care includes counseling, support, and empowerment in addition to medical treatments. It is a comprehensive strategy that defends women’s rights, respects their autonomy, and advances their health. To protect women’s health, lower maternal mortality, and advance reproductive justice, access to CAC must be ensured. In order to guarantee that women have the support and tools they need to make educated decisions about their reproductive health, it is critical to promote and emphasize comprehensive abortion care as societies change.
