Physio Techniques In ICU Flashcards
1
Q
Discuss components of MHI
A
Slow (decreased airway resistance, has to dependent regions)
Deep (stretch on alveoli, increased surfactant production and FRC)
Inspiratory hold (collateral ventilation, increased FRC and SA)
Rapid expiration (simulate two phase liquid gas flow, secretion Mx)
2
Q
List precautions and CI to MHI
A
Untrained pneumothorax Nitric oxide Rx Haemodynamic instability Unstable or high ICP Makes pulmonary oedema worse Already hyperinflated PEEP >10cmH2O FiO2 >0.6
3
Q
Discuss detrimental effect of hyperinflation techniques on cardiorespiratory system
A
Risk of volutrauma or barotrauma Increased ICP Decreased venous return and SV Absorption atelectasis Decreased respiratory drive
4
Q
List precautions and indications to naso and pro pharyngeal Suctioning
A
# base of skull or sphenoid Pulmonary resection Severe hypoxaemia Haemodynamically unstable Low platelets CSF leak Pro pharyngeal or oseoohageal surgery
5
Q
List detrimental effects of Suctioning
A
Hypoxaemia Arrythmias Increased ICP Mucosal trauma Bronchospasm
6
Q
Discuss the role of positioning in ICU
A
Altered gas distribution
Increased lung compliance
Decrease complications eg pressure wounds
