Pnf respiratory

Neurophysiological Facilitation of Respiration is a treatment technique used for respiratory care of patients with unconscious or non-alert, and ventilated, and also with a neurological condition

NPF is the use of external proprioceptive and tactile stimuli that produce reflex respiratory movement responses and that increase the rate and depth of breathing

3. Introduction
Respiration:Essential part lung
Breathing: Under control of CNS
Respiratory rhythmicity: central pattern

5. Definition
Neurophysiological facilitation of respiration
is the use of selective external
proprioceptive and tactile stimuli that
produce reflexive movement response in the
ventilatory apparatus to assist respiration.

6. Principal of Respiratory PNF
Use the stretch reflexto facilitate the initiation of
inhalation continue with repeated stretch through
range (repeated contraction) to facilitate an increase
Inspiratory volume.
Appropriate résistance strengthen the muscle and
guide to the chest motion.

8. Aims of PNF
To facilitate normal mechanical
respiratory movement pattern
To decrease muscle spasm
To maintain thoracic mobility
To produce reflex involuntary
respiratory movement reaction

9. Aims of PNF
To activate the diaphragm
To facilitate Inspiratory motor neuron
activity
To facilitate deeper breathing
swallowing and mouth closure

10. Indications
Direct Indications
Inadequate ventilation
Retention of secretions
Need of frequent suctioning

11. Indications
Indirect Indications
Chest mobilization
Trunk and shoulder mobility
Relief of pain
Relaxation
Decrease Spasticity

12. Contraindications
Fracture of Ribs
Active Tuberculosis

13. Effects of PNF
Visibly deeper respiration –larger expansion
of the ribs and increased epigastric excursion
Increased visible tone in abdominal muscles
Change in respiratory rate
Involuntary coughing

14. Effects of PNF
More normal respiratory pattern
Rapid return of mechanical stability
Change in breath sound on auscultation
Retention of improved respiratory pattern after
treatment period
Apparent increase in the level of consciousness

15. Clinical Application
Co-contraction of the abdomen
Vertebral pressure on upper and lower thoracic
vertebrae
Intercostal stretch
Manual pressure(moderate)
Anterior stretch –lifting the posterior basal area
Perioral stimulation

16. Co-contraction of the abdomen
Method: Pressure laterally over lower ribs
and pelvis, Alternate right and left sides
Observation:
Increase epigastric movement
Increase muscle contraction
(rectus abdomens
Decrease girth in obese
Depression of umbilicus
Suggested mechanism:Stretch receptors in abdominal
muscle ,intercostals to phrenic reflex

17. Vertebral Pressure on Upper and
Lower Thoracic Vertebrae
Method: Manual
pressure to thoracic
vertebrae in Region of
T2-T5(Upper) and T7-
T10 (lower)
Observation:Pressure on upper vertebrae –increase
epigastric excursions ,deep breathing. Pressure on lower
vertebrae. Increase respiratory movement of Apical thorax
Suggested mechanism: dorsal root –mediated
intersegmental reflex

18. Intercostals Stretch
Suggested mechanism: Intercostals Stretch
Receptors
Method: Stretch on expiratory
phase maintained
Observation: Increase
movement of area being
stretched

19. Manual Pressure (Moderate)
Method:moderate pressure over thorax
Observation:gradually increased excursion
Over applied pressure area
Suggested Mechanism:Cuteneous afferents

20. Anterior Stretch
Lifting the Posterior Basal Area
Suggested mechanism: stretch receptor in
intercostals ,back muscles. Dorsal root mediated
intersegmental reflex
Method:Hands under lower
ribs, Ribs lifted upwards
Observation:expansion of
Posterior and lateral basal
area
Increase epigastic excursion

21. Peri-oral Stimulation
Suggested mechanism: primitive reflex related to
sucking
Method: Pressure applied to top lip
By therapist finger and maintain
Observation:increase epigastic
excursion deep breathing,mouth
closure, swallowing ,Snout
phenomena
