Q

Pneumona

A

An acute inflamation of the lungs associated with filling of the alveoli with exudates (consolidation)
-Common complication of morbidity and mortality

Pathophysiology
-Infectious agent (bacteria or virus) or irritant reaches the lungs triggering an inflammatory reaction

Etiology:

  • Aspiration
  • Contact (trauma or chest tube)
  • inhalation (droplet)
  • hematogenous (circulation)

Inspection

  • Dyspnea
  • Increase RR (tachypneic breathing)
  • Cyanosis
  • Cough (productive=bacterial, non-productive=viral)

Phases of cardiac rehab

Phase I: Acute/inpatient phase

  • Prepare for discharge, monitor activity tolerance, support risk factor modification technique, provide emotional support, build self-efficacy, and educate on recognizing adverse S & S with activity
  • Interventions focus ob hemodynamic response to exercise, independence in functional activities (transfers, mobilization, etc.
  • Vital signs b4 and after exercise
  • low level intensity

Phase 2: Subacute conditioning phase

  • Typically begins after hospital discharge in the outpatient sertting
  • conditioning exercises with close cardiac monitoring

Phase 3: Intensive rehab phase

  • Exercise in large groups
  • Resistance training typically initiated here
  • *Phase 4: Maintence phase**
  • Pt encourage to continue exercise training in a group setting or self monitored

Q

Pulmonary edema

A

-Abnormal accumulation of fluid in the lungs, fluid from pulmonary capilaries into interstitial space and then onto the alveoli

  • Types
  • Cardiogenic: High pressure (increase pulmonary capillary hydrostatic pressure, LHF

Non-cardiogenic pulmonary edema: Low pressure, increase permeability of the pulmonary capillaries, and alveolar endothelium d/t trauma or toxins (ARDS)

Inspections:

  • Increase WOB, dyspnea, cyanosis, pink frothey sputum (cardiogenic), orthopnea, swelling g in lower extremities if severe
  • Increase tactile fremitus and dull percussion, decrease BS or fine inspiratory crackles on ausciultation
  • CXR: Cardiomegaly, white haziness, kerly B lines, enlarged pulmonary vessels

A

Deep diaphragmatic breathing

  • Pursed lip breathing for COPD (exhalation 3x the length of inspiration)

  • Percussion
  • Vibration

47
Q

3 cycles of active cycle of breathing technique

A

1) Breathing control
2) Thoracic expansion exercise (TEE)
3) Forced expiration technique

Advantage that the airways are always open bc the patient is always breathing

48
Q

3 stages of autogenic drainage

A

1) Unstick (Exhaling to low volumes (ERV) will mobilize mucus (5-6 reps, with a 3 second hold)
2) Collect : Mucus will collect when breathing in mid lung volumes (5-6 reps1 with 3 second hold)
3) Evacuatee: Evacuation of mucus occurs when breathing into larger lung volumes (5-6 reps, 3 second holds). May perform cuff or huff at the end.

At the end of one cycle perform 203 hufss/coughs followed by deep breathing to prevent airway closuree

-Treatment time 30-45 minutes/session once a day

49
Q

4 stages of a cough

A

1) Inspiration
2) Glottic closure
3) Compression
4) Expulsion

Huff is prefered to a cough in patients with obstructive lung disease due to the risk of small airway closure
